Electrical Engineers build a wide variety of products and work in almost all industries. They design control and communication systems, sensors, displays, learning machines, robots, instruments, voice recognition, computer vision, electronics, motors, power systems, the internet of things—the list goes on and on. Required study includes electronics, microprocessors, digital circuit design, control systems, communication systems, power systems, signal processing, and software. Electives can then be chosen to learn more about any of the above fields or even bioengineering. It allows more freedom in choosing electives than Computer Engineering, and thus is a very flexible degree that allows the holder to work on a wide variety of applications utilizing vastly different skills. This allows our graduates to choose careers best fitting their exact interests. For instance, some of our graduates develop complex new mathematical algorithms to achieve the highest possible system performance; others work with basic physics to develop better circuits and devices; others work outside in the field to Improve the generation and transmission of electric power; some become high-level executives at companies like Google; others complete law or medical degrees. The Bioengineering option of Electrical Engineering provides the right training to design medical instruments and with a few additional courses becomes a full Pre-Med or Pre-Dental major. After graduating, our students have gone on to the world’s best graduate programs: Stanford, MIT, Johns Hopkins, etc.
Computer Engineering is a blend of Computer Science and Electrical Engineering. In fact, a Computer Engineering student can change majors to Computer Science within the first three semesters without losing any credits. More careful planning is required to switch from Computer Science to Computer Engineering. Computer Engineering students receive training that allows them to design complex computer systems and embed them in custom applications such as robots, spacecraft, automobiles, etc. A typical system may interface with a sensor to measure the world, then decide how to best use the information to achieve goals and eventually turn on actuators which perform the needed task. They also develop computer vision systems, high-performance computers and software, and the internet of things. They take many of the same required courses as Electrical Engineers, but fill in their electives with computer-specific courses. Graduates have the ability to design electric circuits, understand network hardware, design computer systems, and write the software inside those systems. Compared to Electrical Engineers, Computer Engineers have less breadth of knowledge in Electrical Engineering but more depth in software and computer hardware. Compared to Computer Scientists, Computer Engineers know much more about hardware and signal/system theory. Computer Engineers sometimes also major in either Electrical Engineering or Computer Science to get two degrees. Our students have gone on to the world’s best graduate programs and top companies.
Thu, 12 Jan 2023 17:23:00 -0600entext/htmlhttps://www.uwyo.edu/electrical/index.htmlKillexams : Hot, New Electric Cars That Are Coming Soon
There’s a new electric vehicle company in town: VinFast. Its home base is in Vietnam, and it plans to invest $4 billion in a manufacturing plant in North Carolina. The automaker showed two SUVs at the 2022 New York auto show, the VF 8 and VF 9.
Both the VF 8 and the VF 9 feature a dual-motor all-wheel-drive system. The Eco version has 348 hp, and the Plus trim has 402 hp. Standard and long-range batteries are available in either model. VinFast says the VF 8 Eco with the standard battery has a 260-mile estimated driving range and a 5.8-second 0-to-60-mph time, while models equipped with the extended-range battery have an estimated 292-mile range and a 5.3-second 0-to-60 time.
VinFast has a unique twist on pricing, with a battery subscription on top of the vehicle’s purchase prices, tailored to the buyer’s expected usage. The company explains it this way: “By separating the price of the battery from the acquisition value of the automobile, VinFast takes on all the risks related to the vehicle’s battery and ensures a reasonable price for its products, while providing customers with peace of mind about the battery’s quality during use.”
A key upside to their battery approach is that VinFast provides a lifetime battery warranty covering all maintenance and repair costs, and will replace the battery free when charging capacity dips below 70 percent. This should reduce some concerns among shoppers.
Prices: VF 8: $40,700 to $48,000. VF 9: $55,500 to $61,000 On sale: Winter 2023

An electric pressure washer is an excellent piece of equipment because it produces dramatic cleaning results. It can quickly and safely wash a muddy vehicle or strip grime and goo from patio furniture, decks, or the siding on a house. Cleanup jobs that take a lot of time and elbow grease with a scrub brush and a garden hose are achievable within minutes using a pressure washer.
Pressure washers use pumps and engines to amplify water pressure, turning your garden hose into a high-powered cleaning machine. There are two general types of pressure washers: electric-powered and gasoline-powered. While gas-powered pressure washers typically offer more power, electric pressure washers are growing in popularity for their combination of cleaning power, portability, and overall versatility. Plus, the best electric pressure washer models can tackle many of the same jobs as gasoline-powered washers used by professionals, and they are more affordable, lighter, quieter, and easier to store and maintain.
There are many electric pressure washers on the market with a wide range of features, so it can be tough to choose the best electric pressure washer for your cleaning projects. In order to figure out which models are right for different jobs, we chose some of the most popular models and tested them for cleaning power, portability, and versatility.
Keep reading to learn more about shopping considerations, and take a look at our detailed hands-on product reviews of some of the best electric pressure washers on the market.
Electric pressure washers can clean the same surfaces as larger gas-powered ones. Choosing an electric option means sacrificing a bit of pounds per square inch (psi) and gallons per minute (GPM), which translates to cleaning speed—but electric versions have upsides, too. They eliminate the need to purchase and store gasoline; do away with exhaust fumes; and cut the machine’s noise, size, and weight in about half. Electric pressure washers offer aggressive cleaning power without the hassle of gasoline. We used these considerations to develop our criteria for our hands-on tests.
In our tests, we evaluated cleaning power, range, and mobility along with ease of transport and storage. Our driveway test area included multiple surfaces for cleaning, such as a lawn mower, car tires, vinyl house siding, and the concrete driveway. Scoring favored practical strengths that affect the user’s experience, like hose length and flexibility, spray gun trigger stiffness and kickback, spray nozzle and accessory options, ease of mobility during cleaning, noise, and perceived durability.
Our Top Picks
Portability, size, power, cord length, and accessories are some of the top features that set some electrical pressure washers ahead of others. Check out the individual product reviews ahead to learn how each pressure washer performed in our hands-on driveway tests.
Those needing more cleaning power for more significant projects like siding, fences, and driveways may want to consider the Greenworks 2,300 psi electric pressure washer. The higher pressure and flow rates of 2,300 psi and 2.3 GPM help get the work done faster. A bulky frame and large 10-inch wheels allow easier access to projects located away from paved surfaces. The kit includes a turbo nozzle and four spray tips: soap and 15, 25, and 40 degrees. It also includes an onboard injection system for dispensing cleaning solutions.
We found the spray wand grip and trigger comfortable to work with. The 25-foot flexible hose was easy to maneuver while cleaning all sides and under the hood of a riding mower. Combined with its 35-foot power cord, this washer has lots of reach. Its biggest downside will mostly impact those short on storage room, as they might find this pressure washer a bit of a space hog.
Hose length: 25 feet
Large 10-inch wheels move well on all terrain types
Upright configuration with tall transport handle and comfort grip make it easy to move
Flexible 25-foot pressure hose maneuvers easily and provides a long reach
Onboard soap tank and 5 nozzles for a variety of cleaning projects
Bulky frame takes up more storage space
There’s a bit of a lag between triggering and pressurizing that takes some getting used to
Whether you’re washing the deck or detailing the car, a rugged mobile pressure washer makes the job simpler. The DeWalt 2,400 psi electric pressure washer comes equipped with the power and accessories necessary to make cleanup quick and easy. DeWalt’s 13-amp axial pump motor creates 2,400 psi of water pressure at a flow rate of 1.1 GPM. The onboard soap tank and five assorted quick-connect spray nozzles ensure no cleaning project is too demanding.
The upright frame and inflatable rubber tires on this DeWalt pressure washer made it easy for us to maneuver around the yard. All its hose connectors and other hardware components felt durable and assembled securely. The 25-foot pressure hose and 35-foot power cord offered a long reach for easy access to water, electrical outlets, and our cleaning projects. Its flow rate of 1.1 GPM was lower than most of the tools we tested, and while it was still effective for most projects, it didn’t clean as quickly as our top pick.
Hose length: 25 feet
Upright configuration and air-filled rubber tires make it easy to maneuver on uneven ground
Built to last with sturdy hoses, connectors, and other hardware
Includes a built-in soap tank and 5 assorted nozzles for tackling an array of cleaning projects
1.1 GPM flow rate conserves water but cleans more slowly than competitors with higher flow rates
Spray gun does not fit securely in the tool rest, making it more cumbersome to transport
If you’re looking for a quality pressure washer on the cheap, look no further than the Sun Joe 2,030 psi 1.76 GPM electric pressure washer. Anyone willing to do a bit of assembly will be rewarded with a unit that boasts midrange cleaning power and better-than-average hardware.
Although assembly was necessary to get this unit up and running, the whole process only involved installing four parts with four screws and took less than 5 minutes. The housing and handle were plastic and felt a bit cheap, but everything lined up properly, and once assembled, it was sturdy. We had no other complaints—the pressure hose, spray gun, and connectors were of good quality, and the quick-connect spray nozzles worked comparably to the more expensive models.
In action, the Sun Joe electric pressure washer performed well on all our projects. Both the pressure and flow rate felt moderate. While performing the annual deep cleaning of a riding mower, it only left behind some of the hard-to-remove deeply embedded dirt and grass clippings around the discharge chute.
Hose length: 20 feet
Bargain price for a well-equipped pressure washer with good cleaning power
Includes dual soap tanks and 5 assorted nozzles for a range of cleaning tasks
Lightweight construction makes it easy to maneuver, transport, and store
High-quality pressure hose and hardware

Plastic body, wheels, and handle feel less durable than the competition
This Wen pressure washer produces up to 2,000 psi with a water flow of 1.6 GPM, which is enough power to clean a deck or lawn equipment. It’s just under 14 inches tall and wide and weighs just 20 pounds—about the size and weight of a small cooler full of ice—so it’s easy to move around. The Wen washer has a 36-foot power cord and a 16.5-foot hose, so it can clean objects relatively far from an electrical outlet and water source. This model includes a detachable soap tank plus a built-in nozzle adjustment to change the angle and pressure of its spray.
At first glance, the Wen looks more like a portable tire inflator than a pressure washer. It is very lightweight and has no wheels or place to store the power cord or pressure hose when not in use. But it proves itself admirably in operation, with enough water pressure and flow to wash a car, clean patio furniture, or eliminate a driveway stain. Although very portable in the sense that it is small and lightweight, making it easy to load up in the car, this pressure washer lacks maneuverability while cleaning. It’s best, and surprisingly effective, for small tasks.
Hose length: 16.5 feet
Compact unit is easy to load in a car or store in smaller spaces
At about 20 pounds, it is lightweight and easy to carry
Plenty of power for basic chores like washing automobiles, lawn equipment, etc.
Lacks onboard storage for the hose, wand, and power cord
Needs a carrying case or a tote to store everything together
Lacks wheels; needs to be carried from place to place
Some cleaning jobs must happen without a convenient electrical outlet or water spigot nearby. With the Ryobi 40-volt cordless pressure washer, there is no need to resort to a scrub brush. It runs on rechargeable batteries and has the ability to siphon water from a bucket.
With up to 45 minutes of runtime per charge, this is a great option for small to midsize chores. In normal mode, it produces 1,000 psi at 1.2 GPH, and with the press of the boost button, it bumps up to 1,500 psi at 1.2 GPH. The motor and soap tank feature a compact cube-shaped design with a telescoping handle and rear wheels that stores easily and maneuvers well on hard surfaces.
The Ryobi 40-volt cordless pressure washer comes equipped with a soap nozzle, a 15-degree nozzle, and a turbo nozzle that rotates the pressurized stream to increase cleaning power. Two 40-volt 6-amp-hour batteries and a rapid 2-hour charger come with the kit.
In our tests, this cordless pressure washer impressed more with its versatility than its cleaning ability. For remote cleaning needs, it could be a handy helper. The compact build and ability to use water from either a spigot or a nonpressurized source make it a nice option for RVers, boaters, and others who may have to clean where electricity and running water are unavailable. On the other hand, its top cleaning power (in boost mode with the turbo nozzle attached) ranked at the bottom of all the models we tested. It worked well to remove dirt and debris from smooth surfaces, but it was not very effective for cleaning concrete.
Hose length: 25 feet
Two 40-volt 6-amp-hour batteries offer up to 45 minutes of runtime per charge
No water spigot required; capable of siphoning water from a bucket
Power-boost mode increases pressure by 500 psi
Lowest total cleaning power of all the models we tested
Only 20 minutes of runtime on power-boost mode
More expensive than the top-performing plug-in electric models
The Greenworks 1,800 psi electric pressure washer is a good choice for tackling lighter projects around the house. This machine produces up to 1,800 psi and has a water flow rate of 1.1 GPM, which is enough power for cleaning boats, patios, or siding. It comes with three quick-connect tips in varying angles, a soap nozzle, an onboard soap tank, a 35-foot power cord, and a 20-foot hose. The long hose and cord let you reach jobs far from an electrical outlet, and it has a rack that holds the nozzles—a nice feature that keeps them organized and close at hand.
We like that this light-duty pressure washer is built with large 8-inch wheels and a sturdy frame, which are conveniences not typically found on light-duty machines. The upright hand-truck-style frame made it easy to roll across the grass to wherever we needed it. The 20-foot pressure hose was good for cleaning all the crevices of a rototiller, but it was a bit stiff as we moved from side to side.
Hose length: 20 feet
Large 8-inch wheels roll easily over grass and uneven surfaces
Comfortable grip and trigger operation is ideal for extended use
Good reach with a 35-foot power cord and a 20-foot pressure hose
Tough jobs like cleaning the driveway, deck, or patio call for a heavy-duty tool like the Greenworks Pro. It delivers 3,000 psi at 2.0 GPM for powerful cleaning action. Included in the kit are 15-, 25-, and 40-degree spray tips; a soap applicator tip; and a turbo nozzle. A 1-gallon detergent tank holds a full bottle of cleaning solution for direct injection into the spray stream, and the pressure hose is 25 feet long for ample range. Built on a tubular steel wheelbarrow-style frame, this unit has a low center of gravity and large 10-inch wheels for stability on uneven ground.
Outstanding cleaning capability combined with an excellent working range and a highly flexible hose made it a pleasure to work with. This pressure washer was the most capable when it came to washing concrete, cleaning nearly twice as fast as the next closest performer. Although some storage space can be saved by standing the unit vertically on the front of its frame, storage could remain a problem for those who are spatially challenged.
Hose length: 25 feet
Horizontal wheelbarrow-style build with a stable low center of gravity
Pliable 25-foot pressure hose was easy to maneuver
Good pressure and water volume for larger cleaning projects
Bulky frame takes up more storage space
Transport handle is only 23 inches high, which will likely be uncomfortable for taller users
No lower spray gun support makes travel somewhat awkward
The Westinghouse packs 2,050 psi and has a water flow rate of 1.76 GPM. It can handle cleanup jobs ranging from light tasks like cleaning cars to heavier tasks such as desliming sidewalks. The washer has four 3-inch casters that rotate 360 degrees, so it can turn on a dime and is easy to maneuver as you work. At just under 17 inches tall, it has a low center of gravity that makes it hard to tip over. The Westinghouse comes with four nozzles, a 25-foot hose, a soap applicator, and an onboard soap tank to pump up the cleaning power on your tasks.
Working with the Westinghouse feels somewhat like using a wet/dry vac, in a good way. A feature unique to this four-wheeled pressure washer is that if the casters are unlocked, it can follow the operator with just a slight tug. The pressure hose had a high degree of flexibility for excellent maneuverability. While it may not be the best choice for big projects out in the yard, it’s a great choice for most cleanup jobs taking place in the driveway.
Hose length: 25 feet
Four 3-inch locking casters roll easily on hard surfaces
Compact size is easy to store in tight spaces
Surprisingly strong cleaning power in a small package
Locking/unlocking the casters may not be convenient for some
The transport handle is best for carrying, not rolling
A pressure washer is essential for driveway cleanup. This Ryobi is built for all-purpose cleaning, easy transport, and convenient storage. With a water pressure of 2,300 psi and a flow rate of 1.2 GPM, it is capable of cleaning up the driveway, washing the car, and performing many other everyday tasks. The 25-foot pressure hose and 35-foot extension cord deliver it plenty of range for washing large areas. Its upright, hand-truck-style build and large 12-inch wheels make it easy to move this pressure washer around the yard while minimizing its footprint in storage. The kit comes with a turbo nozzle, two spray tips, and an onboard detergent tank.
The hose connections on the Ryobi are some of the most easily accessible of all we tested. The pressure is adequate for most cleaning jobs, but the flow rate feels somewhat low for bigger projects. That said, it thoroughly cleaned 20 square feet of filthy concrete in about 5 minutes.
Hose length: 25 feet
Large 12-inch wheels roll easily over all surfaces
35-foot power cord and 25-foot pressure hose offer excellent reach
Includes turbo (spinning) nozzle and 2 fan nozzles
High-pressure unit can deep clean tough stains
Hose is stiff and cumbersome during setup and pack up
Flow rate of 1.2 GPM may be too low for larger projects
Detailing a vehicle requires more than just a strong jet of water. The Earthwise offers plenty of water power at 2,050 psi and 1.4 GPM, along with a host of extra tools. The kit includes 0-, 25-, and 40-degree spray tips, a soap applicator tip, a turbo nozzle, a hub brush, a fixed brush, and a foam cannon. A 36-foot power cord and 20-foot pressure hose offer good range and mobility.
In testing, this was our top choice for cleaning power equipment. Using just the spray tips and turbo nozzle, standard equipment among all the pressure washers we tested, we removed heavy caked-on dirt. The foam cannon and brushes made quick work of surface residues and embedded grime on tires and rims. Pressure and flow rate were effective without risking damage to painted surfaces. Our only negative comment is about the pressure hose, which is stiff and could be a few feet longer for better reach and maneuverability.
Hose length: 20 feet
Includes a wide assortment of cleaning tools to handle a range of jobs
Pressure and flow rate clean well without the risk of damaging paint
Slim upright design is ideal for easy storage
Brushes and foam cannon cannot be stored on the washer housing
Pressure hose is stiff and cumbersome when not pressurized
Although this electric pressure washer from Wholesun is offered up as a compact, powerful tool with numerous conveniences, unfortunately it did not prove to be so in our tests. It didn’t seem to produce its advertised pressure or flow rate, and the motor sounded as though it was struggling. In order to clean concrete, the spray tip had to be within very close range, and even then, it only cleaned a 2-inch strip per pass. The hose reel actually impeded setup and storage—pulling out the hose caused the unit to fall over. The small reel size and collapsible crank felt extremely awkward and flimsy. In terms of cleaning power, portability, effectiveness of accessories, and overall quality, it did not meet our standards.
What to Consider When Choosing an Electric Pressure Washer
Keep the following factors in mind while shopping for a pressure washer so you can find one to use for years to come.
The amount of power a pressure washer has is measured in a combination of psi and flow, measured in GPM.
Psi indicates the water pressure delivered by the machine. The higher the psi, the more powerful the pressure washer and the more effective it will be at cleaning deep stains. Electric pressure washers typically range between 1,500 and 2,500 psi. A machine with a lower psi rating can do almost all the jobs a more powerful machine can do, but a machine with higher psi can do it faster.
GPM measures the volume of water delivered by the pressure washer, which in tandem with psi, measures how fast the electric pressure washer will clean. Higher GPM electric pressure washers are more powerful and clean faster than models with lower GPM.
Cleaning units assign a relative value to the pressure washer’s total cleaning ability. It’s a helpful measurement for comparing different models with varying psi and GPM values. Calculate cleaning units by multiplying the psi by GPM.
Determining the proper hose length has a lot to do with the task at hand. Washing a full-size pickup truck might require a 25-foot hose so you can walk around the truck without dragging the pressure washer or pulling it over. On the other hand, pressure-washing a deck might not require all that length and could actually be a hassle to drag as well as a tripping hazard.
There are two main types of pumps used in pressure washers: axial and triplex. Most electric pressure washers have an axial pump. Axial pumps are maintenance-free, meaning the oil doesn’t have to be changed. However, an axial pump can’t be rebuilt, and its seals or valves can’t be changed like those of a triplex. Once an axial pump fails, a new pump will need to be purchased, or the entire pressure washer will need to be replaced.
Most pressure washers come with replaceable nozzles that fit onto the tip of the pressure-washer wand so you can customize the water stream’s angle or intensity. Nozzles are measured in angles ranging from 0 to 40 degrees. The higher the angle, the lower the water pressure.
A 40-degree nozzle might be used to wash a car or the siding on a house; a 25-degree nozzle might be used for general tasks; and a 0-degree nozzle may be used for the toughest cleaning jobs, like getting an oil stain out of a driveway.
Ease of Use
An electric pressure washer is easier to use than a gasoline pressure washer. It doesn’t need oil changes, spark plugs, or throttle adjustments. It doesn’t require a tricky pull start, either. The user just hooks up the hose and throws a switch to turn the machine on. Electric pressure washers are also a lot quieter than gasoline-powered pressure washers.
Another ease-of-use feature to look for is quick-connect fittings for nozzles and hoses. These spring-loaded fittings snap on and off quickly and easily—no wrench is needed.
Electric pressure washers are smaller and lighter than gasoline-powered models. Some electric pressure washers aren’t much larger than a cooler and are easier to store.
It’s a good idea to pick an electric power washer that balances power with portability. Generally, the more powerful the pressure washer, the heavier it is. The ideal model is light enough to move around the yard or house without straining the user, yet it still contains the power needed to get the job done.
Deciding on an electric pressure washer can take measured research and assessment of needs. If you still have questions about using an electric pressure washer or caring for one, read on.
Q. How do you use an electric pressure washer?
Pressure washers are powerful enough to cut or hurt a person or an animal. When using a pressure washer, wear safety glasses and closed-toe shoes. Also, keep your hands away from the end of the wand, and don’t point the nozzle at anyone.
Using an electric pressure washer is straightforward:
Choose the least aggressive nozzle that will get the job done and install it in your wand.
Attach your garden hose to your outside faucet and the inlet on your pressure washer.
Plug the pressure washer into an outlet (skip this step for cordless models).
Turn the machine on.
Squeeze the trigger to spray the surface.
Q. How do you winterize an electric pressure washer?
Many electric pressure washers are small enough to be stored indoors and won’t need winterizing. If storing one outdoors at the end of the season, drain all remaining water from the pump and hose of the pressure washer, and pump a mixture of antifreeze and lubricant through the system. Consider using a premixed pump-specific solution for the job.
Q. Why does my electric pressure washer keep shutting off?
When you turn on the pressure washer for the first time, it will run to prime the pump and pressurize the system. It will stop running when it’s pressurized. It will begin running again when you pull the trigger. If it won’t start in the first place, there may be a different issue.

They’re affordable, safe, and efficient, with versatile cooktops and consistent ...Mon, 18 Apr 2016 03:23:00 -0500entext/htmlhttps://www.nytimes.com/wirecutter/reviews/best-electric-and-gas-ranges/Killexams : The Best Electric Stoves Of August 2023
The size of the electric stove you’re interested in should be one of the most important factors when making a purchase. You likely don’t want to rearrange your whole kitchen to fit a new stove, so it’s important to have accurate measurements of the space where the new stove will sit.
In addition to the dimensions, buyers need to consider the size of the stove in terms of how many burners and ovens it will have. Stoves can have more than four burners and one oven. Plus, buyers need to consider the size of the oven to know how much it can fit.
There’s the style of stove you want, like a four-burner vs. a six-burner, a coil range or a smoothtop range, but there’s also the style your stove can bring to your kitchen. Stoves can come in a variety of colors outside of the usual black, white and stainless steel models. Stoves are nearly available in every color.
As the name implies, electric ranges are powered by corded electricity, drawing around 2,000 to 5,000 watts. Electric ranges are available in six to nine-burner configurations, and each element on the range will have a different wattage, with the largest typically using the most power. The burners can be set at different heat levels for small and large pots.
The more powerful your element is, the quicker it can cook food. But don’t be fooled into thinking that power means bigger is better—these high-power elements use more electricity and require more maintenance. Lower wattage elements are better for slow cooking, warming food and bringing water to a slower boil.
If you are shopping for an electric range, you will want to ensure that your new range’s wattage is no higher than what you currently have in your home. Using a range with too much power can damage some cookware and cause damage to your home wiring.
These days, stoves come with all sorts of bells and whistles. Want an air fryer? Your stove can do that. You can also choose induction cooking ranges that will help cook food more evenly.
Be sure to take a look at the cubic foot capacity so you know how much you can fit into the oven at one time. Ovens can also have two or three racks, which could be an important factor, depending upon how much you cook in the oven.
Some of the more advanced and new electric stoves have an array of settings available, so it’s best to consider what you will use your range for.
For instance, electric ranges offer unparalleled cooking flexibility with features like convection cooking, a broiler, an induction cooktop and even Wi-Fi compatibility, allowing you to operate and monitor your range remotely via an app on your phone or tablet. Not to mention, some electric stoves come equipped with self-cleaning functionality so that you can knock another chore off your to-do list.
Remember, a more expensive range with more features will cost an extra amount in repairs should they ever need it. So buying one with only the settings you need is a better option as they are less expensive and will last longer.

The best electric bikes are rapidly becoming one of the best alternatives to using your car. Electric bikes come in all shapes and sizes — from folding models that you can carry around, to large cargo bikes that can haul all your groceries and kids around town. They're great from getting back and forth to work, or if you simply want to take a nice long ride.
Electric bikes have small motors that deliver you an extra boost when you need it, making it easier to travel up hills and longer distances. What's more, the best electric bikes are simply fun to ride. They'll make you feel like a kid again, even if it's just for commuting.
Because electric bikes are so hot, there are hundreds of models available — but that also means that there are a lot of duds out there, too. We've tested a number of the top models to deliver you the best recommendations for all kinds of electric bikes.
While many of the best electric bikes are expensive — upwards of $2,000 — they're coming down in price; in fact, we also have a list of the best budget electric bikes under $1,500. And before you do any riding, be sure to pick up one of the best bike helmets to keep your head safe, and one of the best bike locks to keep your ride secure.
This futuristic-looking ebike is made from carbon fiber, which keeps its weight to just 36 pounds. It has a speedy electronic shifter, responsive and powerful motor, and a great range for something this small. It ain't cheap, though.
For the vast majority of riders, the Rad Power RadCity 5 Plus will be the best electric bike. It has a comfortable design, plenty of power, and a multitude of mounting points for things such as baskets and child seats. Plus, it comes with a rear rack and mudguards. Its 7-speed shifter, combined with three levels of pedal assistance and a twist throttle is more than enough to get you up even the steepest of hills.
We really enjoyed pedaling around on this bike, which is offered in both step-through and step-over models. Its battery, while not fully integrated into the downtube, provides plenty of range, and can also be used to charge your phone (with the right adapter). At a starting price of $1,999, it's reasonably affordable, too.
Battery:Removable Lithium-Ion 36V, 9.6Ah (360Wh) with LG cells
Max estimated range:46 miles, depending on assist setting
Max assisted speed:20 mph
Motor:36V, 350W brushless rear hub motor with torque sensor
Reasons to buy
Easy to read head unit
Reasons to avoid
Motor feels underpowered
The Aventon Soltera.2 is the successor to our previous top pick among the best budget electric bikes. This modestly priced model costs less than $1,500, yet sacrifices very little in the name of economy. In our tests, we found it very comfortable to ride, and it looks great, too. We also liked that it has features you won't find on other budget electric bikes — namely, the built-in turn signals, which are a real help when riding in traffic.
However, the Soltera's rear hub motor does feel a little underpowered, especially on hills, but thanks to a torque sensor, it's a lot more responsive than the original Aventon Soltera. If you're looking for a low-cost electric bike to get you around town, this is definitely the model to pick up. Be sure to check out the best budget electric bikes for more picks.
If you plan on commuting to work, Charge Bikes City may well be the best ebike for you. Not only does it come with features like full-fenders to keep the mud off and a rear rack for a pack or bag, but it does everything well for a very reasonable price. The Charge City has a five level power assist, as well as a full-power throttle button, should the need or hill arise. It comes with all the necessary bells and whistles a commuter is going to want, including the bell (actually a superior and very loud electronic horn). The bike is available in both step-over and step through, and in a few color options, too.
The handle bars fold flat, for easy storage in an apartment or cubicle, and the City's electric support is so smooth you'll think you're doing all the work yourself. We were able to do three days plus of typical city commuting before having to re-charge. At night, the bike's lights sufficiently lit up the road and the throttle helped us zip around potential trouble when we felt out of gas. Founded by folks from biking icon Cannondale, Charge's sui generis feature is that even newbies can assemble the bike right out of the box in 10 minutes or less. All you basically have to do is put the front wheel on.
Throttle adds assist over your pedaling assist when needed
Reasons to avoid
Could use a center stand rather than kickstand
While it can't haul as heavy loads as some other larger (and much more expensive) cargo bikes, the RadPower RadRunner 3 Plus is more than capable of carrying you, your kids, and plenty of groceries wherever you need to go. We loved its responsive 750W motor, its comfortable ride, and its low center of gravity, thanks to its 3.3-inch thick, 20-inch tires.
What makes the RadRunner 3 Plus stand out is its versatility: You can outfit the bike with any number of combinations of racks, seats, bags, and other accessories to truly customize it for your needs. And, its relatively low price for a cargo bike makes it a real bargain for those looking to replace their car with an electric bike.
This fat tire ebike will get you anywhere you need to go
Max estimated range:60 miles
Max assisted speed:28 mph
Motor:750 watts, 48V, rear hub motor
Gearing:Shimano Acera 8-speed rear derailleur
Wheel diameter:26 inches
Reasons to buy
Very fun ride with excellent pedaling assist response
Stable and capable in all conditions, including snow
Has both lights and turn signals
Reasons to avoid
Very heavy bike
Suspension fork is unnecessary
If you're looking for a fat-tire electric bike that's less than $2,000, the Aventon Aventure.2 is hard to beat. It's as good off-road as it is on pavement, has a beefy battery and a clear color display, as well as fenders that'll save your clothes from getting too muddy. Other niceties include a brake-activated rear light and turn signals.
The Aventure.2 has both pedal-assist and throttle modes, and the battery and wires are neatly integrated into the frame. What's more, the battery can be removed for charging. While not as capable as a dedicated mountain bike, the Aventure.2 was able to get us up and over hilly terrain, and its torque sensor was quick to translate our pedaling into power. Our only real critiques were the bike's 77-pound weight and its front suspension fork, which felt unnecessary. Otherwise, it's an excellent bike for the price.
The Gocycle G4i+ looks like something a supercar designer would build, which isn't surprising given that it was conceived by former McLaren sports car engineer Richard Thorpe. Not only is this bike's unique wheels-on-one-side and tapered body eye-catching, it is also able to fold up in a couple of minutes into a size small enough to get by security and into the office elevator. At 36 pounds, it's one of the lightest folding electric bikes out there, too.
Despite that, this bike was a real pleasure to ride. Its electric shifter responded near instantly, as did the pedal assist and throttle. However, while the G4i+ has daytime running lights, you'll have to pay extra for a legit headlight, as well as mudguards. Also, the G4i+ has a great smartphone app, but one of the flimsiest methods of holding your phone on the bike itself — a cheap solution for a bike that costs $7,000.
If you're looking for something slightly more affordable, GoCycle also sells the G4i ($5,999) and the G4 ($4,799). A 2022 version of the G4 has an injection molded composite mid-frame.
Gearing:Shimano 7-speed, 11-32 cassette and 44T chainring
Reasons to buy
Good assist power when pedaling
Comfortable to ride
Reasons to avoid
Suspension fork seems unnecessary
The Ride1Up Turris is a solid e-bike that doesn't cost a lot, but delivers plenty. It starts with its powerful 750W motor, which was quick to engage and carried us up hills with ease.
We also liked all the niceties that came with the bike, including a front headlight, front and rear fenders, an easy-to-read display, and nice, wide tires that made it easy for us to get across all kinds of terrain.
However, there's some assembly required: We had to attach the fork, one crank arm, and the fenders, all of which needed some adjustment. If you're unfamiliar with putting bikes together, you may need to make a trip to your local bike shop.
Motor:Bosch Performance Line 3.0 65 Nm mid-drive motor
Gearing:Enviolo 380 stepless gear system
Wheel diameter:28 inches
Weight:54.6 lbs. (with battery)
Reasons to buy
Frictionless electric power
Top combination of accessories
The Gazelle Ultimate C380 HMB is one of the smoothest-riding electric bikes we've tested. Thanks to a Gates belt drive and seamless Enviolo shifter that allows you to change gears in the middle of a hill, everything about this bike is effortless. Its low-step frame is topped with a Selle Loire Gel seat with an internal compression post to soften the ride. The aluminum frame also has an internal front fork suspension system and removable battery to keep the whole design as svelte as possible.
The Gazelle has full mud guards, a metal belt guard (to keep your pants clean), kickstand, lights front and back, a rear rack with a built-in stretch bracket, and even an Axa Defender lock that immobilizes the rear wheel when you snap it shut and remove the key. But, all of this will cost you: The Gazelle Ultimate is a steep $4,800.
Battery:PowerPack 500 Battery with 250W and 36V of power
Motor:Bosch Cargo Line Cruise Motor+
Gearing:Shimano Deore 10-speed drivetrain
Size:8.5 feet long
Range (est):60 miles
Reasons to buy
Stable, fun ride
Lots of cargo space
Quick, responsive, and powerful motor
Reasons to avoid
Bumps can be a bit jarring
The Yuba Supercargo CL can haul an astounding 500 pounds, making it one of the heftiest electric cargo bikes in its class. Yet, it offers a surprisingly stable ride, thanks to its low center of gravity. Its cargo area is very customizable, letting you convert it from a place to carry groceries to a space to tote your tots to soccer practice.
Magna hydraulic brakes and a Bosch mid-drive motor were very responsive, though the relatively small 20-inch tires and lack of suspension did make bumps feel a bit jarring. The Supercargo CL starts at around $6,000, but is incredibly customizable; you can select from a range of accessories to adapt the cargo area to suit your needs.
The all-weather Biktrix Stunner X is equally at home in the mud and snow as it is on pothole-dotted city streets, keeping the rider comfortable and in control no matter the terrain or conditions. It's got enough of a kick to get you up a gravel hill, and enough padding so that your ride doesn't turn into a torture test.
Its Bafang 750W mid-drive motor is surprisingly powerful, and can be used in pedal-assist as well as throttle mode, for when you want to deliver your legs a break. While not as nimble as purpose-built electric mountain bikes, it performed admirably on mud-slicked roads. Our only real critique is that the Bafang controller was a bit difficult to master.
Backsweep on handlebars puts wrists at awkward angle
Very heavy and long
While a lot of cargo ebikes can carry kids, the Urban Arrow Family is the best electric bike for the job. We really liked its stability and the ease with which we could start this massive bike from a dead stop. This is not a small bike: it's 9 feet long and weighs 110 pounds, which is a good thing that it also has one of the best kickstands we've seen yet from a bike.
The cargo area is made of thick EPP foam, which is designed to absorb impacts. The seats — there are also adjustable seatbelts — are also fairly low, which keeps the center of gravity low. As you might expect from such a large bike, its range is fairly limited — around 31 miles — but the battery is removable. Overall, it offers an incredibly smooth ride for its size.
Motor:1300W (Peak) 750W (Sustained), Rear Hub Motor
Max advertised range:55 miles
Max advertised assist speed:28 mph
Reasons to buy
Powerful pedal assist with a full-throttle mode
Reasons to avoid
The Juiced Ripracer is a lot more fun than it should be, for a lot less than you might think. It's one of the more affordable offroad ebikes we've tested, and it can go just about anywhere. This fat-tire ride has a 40.3-inch wheelbase and 20-inch wheels designed for trails and other unpaved surfaces, though its lack of shock absorbers means a rougher ride than with so-equipped e-bikes.
This bike has some serious pep, and it flew just about everywhere we wanted it to go. We really liked its low-end torque, which made it great for getting up hills. However, it has a cadence, rather than a torque sensor, so it takes a rotation or two of the pedals for the assist to kick in. As it's a BMX-style bike, the Ripracer is a lot smaller than other mountain e-bikes, which also makes it easier to maneuver around tight spaces.
Wheels are too small and narrow for super-rough roads
If you're looking for something more affordable than the GoCycle, the Brompton Electric C Line Explore is the best electric folding bike for those who need something super-portable. It's also very small and compact, weighing just 32 pounds, yet its 250W motor is strong enough to get you around with plenty of zip. Its battery, which comes in a removable bag that's also great for storing other things, provides up to 45 miles of range — a good long way.
We also like that the C Line has a second pair of tiny wheels that make it a lot easier to roll the bike around when it's folded. Just keep in ming that this commuter-focused bike has smallish 16-inch wheels, so it's not meant to handle rougher roads.
More moving parts means more potential for maintenance/repair
If you're looking to replace your car with an electric bike, then the Riese and Mūller Load 60 should be at the top of your list. Despite its large size and weight, the Load 60 was a delight to ride, with a tight turning radius, full suspension, a Gates carbon belt drive, and a strong and responsive motor assist.
We also loved the startlingly loud horn — a must if you want cars to know you're there — as well as the myriad accessories and options available when configuring the bike. However, if you want the Cadillac of cargo bikes, you'll have to pay Cadillac prices: The Load 60 starts at around $10,000, so you'll have to really consider how much you plan to ride it. But if you do spring for this bike, you won't be disappointed.
Pedal-assist or throttle? All electric bikes have what's called pedal-assist; you start pedaling, and the bike's motor kicks in to make your ride a little easier. But you need to put in at least some work: you won't go anywhere unless you pedal. Most electric bikes will also let you set the level of assistance, so you can decide how hard you want to pedal.
However, some electric bikes will also have a throttle. Press a button or push a lever, and the bike will do all the work for you — no pedaling needed! Using a throttle will quickly eat up the battery life on the bike, so you'll get far less of a range if you don't want to pedal at all.
Motor type Less expensive electric bikes traditionally use a rear hub motor. Mid-drive motors located in the center pedal crank shaft tend to be more expensive but offer better overall balance and smoother shifting.
Motors are also rated based on their power, measured in Watts. Typically, the least powerful motor will be 250 Watts, but unless you're a very large person or planning to go up really steep hills, the motor size shouldn’t be a major determining factor for your purchase. More important, there is no industry standard for measuring Watts (is it continuous or peak and if peak, for how long?). So in general, a motor’s Watt rating isn’t a reliable indication of power.
Battery size Consider where you live. If you're in San Francisco you're going to want more help than if you're cruising around Austin. Watt hours (Wh) is the most important figure for comparison—it takes into account battery output and battery life to deliver you a better sense of available power. Higher Wh translates into more range.
Many electric bike makers will also include an estimated range (usually about 40 miles) that you can get off a single charge. You should take this figure with a large grain of salt, as that number is usually determined under ideal circumstances: A fairly lightweight person riding on flat terrain with no wind, and at the perfect ambient temperature for the battery. Range is also dependent on the level of power assist being used, whether full-throttle has been applied and for how long, and your average speed. As they say, your mileage may vary.
Removable or built-in battery? Most bike batteries will handle rides of about 40 miles and need to be plugged in for at least a couple of hours to get to 80 percent of capacity. So if you have a more demanding commute, consider a model that lets you swap out the battery rather than a bike with an integrated battery.
Also, if you live in a place where you can't bring your bike inside or get close to a wall outlet (such as if you live in a walk-up apartment), definitely look for a bike with a removable battery. It will make your life a lot easier.
Step-over or Step-through? Many electric bike makers will offer their bikes in two configurations: Step-over (which has a top bar that runs parallel to the ground) and Step-through (the bar is angled downwards). Once upon a time, step-through models were traditionally thought of as women's bikes, but that perception is changing. It's generally easier to get on and off a step-through bike, as you don't have to lift your leg over a bar.
Safety features If you're planning to ride your electric bike in traffic or in low-light conditions (such as dawn and dusk), it's worth looking for an electric bike with built-in head and taillights. While increasingly common, it's not a standard feature on all models.
Electric bike FAQ
What are the different types of electric bike?
Generally speaking, electric bikes fall into the same categories as non-electric bikes. Here's a quick summary of some of the kinds of electric bikes you'll find.
Road bike: These are meant solely for riding on roads, and are designed for speed. They will have thinner tires and curved handlebars, so that the rider will be crouched forward. Higher-end models may also be made out of carbon fiber, so as to make the bike as light as possible.
Mountain bike: Designed for off-road use, mountain bikes will have thick, knobby tires, full suspension, and a burlier frame to better absorb bumps and jumps.
Fat tire bikes: Similar to mountain bikes, fat tire bikes are meant to be ridden off-road, usually on very soft ground, such as mud, sand, and snow. As their name suggests, these bikes have very wide tires — as much as four inches — which helps keep a grip on unsteadier terrain.
City/Commuter bike: Made for urban dwellers who need to get around town, a commuter bike will have tires that are somewhere in between a road and a mountain bike. Generally, the bikes will be configured so that the rider's back is vertical when seated, which gives them a better view of their surroundings.
Cargo bike: These bikes are made for carrying heavy loads, and will have a cargo area either in the front or rear of the bike. Because of the payload area, these bikes often tend to me much longer and heavier — and more expensive — than a typical bike.
What is a good speed for an electric bike?
In the U.S., electric bikes are limited to 20 miles per hour; that is, they can only provide you with power — either through pedal-assist or with a throttle — until the bike hits 20 MPH. While you can easily go faster than 20 MPH on an electric bike, the rest of that power will have to be provided by you — or gravity.
How much does an electric bike cost?
Electric bikes range widely in price. Some of the best cheap electric bikes start at around $1,000; you can certainly find models for less, but quality will be less.
The bulk of electric bikes cost anywhere from $1,500 to around $2,500, and there are hundreds of models in this price range.
Higher-end and specialized electric bikes — such as cargo bikes — will cost upwards of $3,000, and can easily reach $6,000 to $8,000, which is a sizable investment.
rules and regulations
There has been a lot of confusion about ebikes (pedal assist versus throttle bikes) and where you can legally ride them. Some municipalities have banned ebikes from bicycle paths, for example. Many places classify ebikes depending on whether they can go full throttle and have a maximum speed of 20 or 28 mph. There are three official classifications:
Class 1: Ebikes that only assist while you pedal, with a top speed of 20 mph.
Class 2: Ebikes with a throttle that don't require you to pedal but have a top speed of 20 mph.
Class 3: Ebikes that only assist while you pedal, with a top speed of 28 mph.
So check your local regulations before you buy. And always wear a helmet.
how we test
All the bicycles in this feature were road (and in some cases, off-road) tested by Tom’s Guide reviewers and staff. Day and night rides, where relevant, are also included and bikes are tested for stability, handling, and safety features (including lights, reflectors, and horns). With an increasing number of models available online only, we also take ease of assembly into account.
