We spent 45 hours on research, videography, and editing, to review the top choices for this wiki. With rechargeable battery-powered pedaling assistance, electric bicycles offer an increasingly viable alternative to fossil-fueled commuting, and e-bikes enable riders of various abilities to extend their range. But the street-legality of these hybrid machines remains a contentious issue, so be sure to check current state and local laws governing their operation before you hit the road. When users buy our independently chosen editorial picks, we may earn commissions to support our work. Skip to the best electric bike on Amazon.
The two most common types of hub motors used in electric bicycles are brushed and brushless. Many configurations are available, varying in cost and complexity; direct-drive and geared motor units are both used. An electric power-assist system may be added to almost any pedal cycle using chain drive, belt drive, hub motors or friction drive. BLDC hub motors are a common modern design. The motor is built into the wheel hub itself, and the stator fixed solidly to the axle, and the magnets attached to and rotating with the wheel. The bicycle wheel hub is the motor. The power levels of motors used are influenced by available legal categories and are often, but not always limited to under 750 watts.
Featuring Bosch’s newest CX Drive motor, the Trekking has enormous torque (that equals acceleration) compared with the rest of the bikes on test. From a standing start the Haibike reaches the 15.5mph European speed limit in seconds. Pair this with mid-sized 27.5in wheels and laid-back mountain-bike geometry, and you have a grin-inducing almost motorbike-like riding experience. This is accentuated off-road, where a rider’s lower average speed is under the motor cut-off point for more of the time, so suddenly the hefty Trekking makes complete sense.
A letter from Casey Evans to Electric Bike Technologies, makers of the E-BikeKit™ electric bike conversion kit system. This one of kind adaptive electric stroller was designed by students from California State University-Sacramento using two 500w direct-drive hub motors controlled by a single E-BikeKit system. Thank you for enabling me to take my daughter hiking! My name is Casey Evans and my daughter, Montel, was born with a very rare...

There are individuals who claim to have lost considerable amounts of weight by using an electric bike.[62] A recent prospective cohort study however found that people using e-bikes have a higher BMI.[63] By making the biking terrain less of an issue, people who wouldn't otherwise consider biking can use the electric assistance when needed and otherwise pedal as they are able.[64] This means people of lower fitness levels or who haven't cycled in many years can start enjoying the many health benefits E-bikes have to offer.

One reason for doing so is the way it is powered, which works in a manner that would be familiar to someone accustomed to a manual transmission car. Like a car, you start in a low gear and work your way up as you gain speed. Since the motor runs through your transmission as opposed to applying power directly to the axle, the gear you’re in really matters. The importance of gearing connects you much more to the road and the terrain, which means you are a more active rider than when using throttle-controlled electric bikes.
What a treat to do business with the folks at Hill Topper. I now have two commuter units one in Idaho and one in Denver my average ride is 25 to 35 miles. I have been riding for about 15 years but being the age of 80 I needed a little help the past few years. I researched electric bikes a few years ago even rode a couple here in Denver but I wanted my own personal look and feel. So about five years ago I found Hill Toppers. What a treat first the units are the best but that is part of the good part the people at Hill Toppers are the very best to work with and enjoy. I had to have a knee replacement last July well thank god for my bike it was the best therapy I could ask for. When in Idaho I get to ride along the Snake river what a treat knowing that I have this unit to help if the wind or rain shows up. When in Denver I cover a lot of area as they have wonderful bike trails all over the area. I ride all of the downtown area and the Cherry Creek dam up and over it takes some effort to get that done but with the help of Hill topper it is a beautiful ride up and overlooking the whole of Colorado. Thank you Andrew,Charles,Sam,Mark.

It's what's inside your motor that sets it apart from the rest. Quality parts and assembly We've written here before about how to choose a motor, the different types of motors, the performance differences between motors, etc. But today I want to show you what makes our motors different from other hub motors. Today, harry is replacing the axle on a customer's direct-drive motor. The bike was crashed and the...
Motor: We have a blog post showing some motor differences: https://www.ebikekit.com/blogs/news/its-whats-inside-your-motor-that-counts Cabling is probably the #1 issue when something goes wrong. Good connectors, good cables, and good assembly (bike shop!) are crucial Strain reliefs on all cable joints! Where you have a junction box or a connector, the stress is concentrated over a small area near this stiff spot on the cable. This can cause small breaks on the internal...

The first functioning electric motor was displayed in the early 19th century, though the device constructed by British scientist Michael Faraday did little more than swirl a wire around a magnet when an electric charge was introduced. Still, the concept proved that electricity could do work. Functional electric motors would follow in many forms after that achievement in 1821. Soon scientists and tinkerers around the world, including visionaries such as Nikola Tesla, were experimenting with all manner of electric motors -- some worked with DC power, others with AC. By the end of the century, myriad electric motors had been produced, capable of exerting enough force with enough reliable control that they were practical for use in myriad applications.

“Our first-generation bike used the same type of 36-volt, 10-amp-hour battery,” he says. “It got between 20 and 30 miles of range, and that’s riding with pedal assist. Using just the throttle you might get 20, less if you’re running on sand or up hills. The charge time is also problematic; with that kind of battery you’re looking at four to six hours, not 90 minutes.”
Installing an electric bike kit is easy to do, can be done in just an hour or so and can last for many years if done right initially. Deciding on the right electric bike conversion kit, the one that suits your riding style and your bike best, is the most important decision you’ll make during this process. Good news... you’ve come to the right place!

Unlike most e-bikes, the Brompton's battery is integrated into a bag that sits on the front of the bike. While that detracts slightly from the classic, streamlined design, it's handy as it can be unclipped for charging or riding as a regular bike – it's probably one of the easiest to ride without battery assistance thanks to its weight. The battery also powers two lights for safe commuting. 


The Liv Amiti-E+2 is a low-priced but highly versatile e-bike. It’s just as much at home on the pavement as it is on bike paths and rail trails. But don't feel constrained to groomed paths. Front suspension and 42mm-wide tires mean you can take on off-road detour on your way home from work. Speaking of work, this e-bike makes a great commuter thanks to rack and fender mounts and integrated lights for riding after dark. Internal cable routing and a nicely integrated battery make for clean lines and 9-speed shifters give you plenty of gearing options for whichever type of terrain you decide to tackle. This do-everything bike is great option if you’re riding includes a little bit of this and a little bit of that.
