In a friction drive motor, a small, solid wheel rotates against the side of the tire in order to drive it. The first motorcycles used the same concept, with a motor mounted above the front wheel. The problem is that the drive rubs at the side of the tire. It's inefficient, and it quickly wears the sidewall away. Tires need to be replaced every couple hundred miles. For this reason, you'll seldom see electric bikes with this type of drive anymore.

Azalea Festival. For the past year, students in CFCC’s mechanical engineering program have been hard...
Because they’re electrically powered, e-bikes sit in a bit of a gray area between bicycles and motorcycles. While some states have enacted specific legislation to state where electric bikes can and can’t be ridden, in other states outdated laws mean they’re regulated as a moped or motor vehicle which can cause confusion over registration requirements, access to cycling infrastructure and how old you have to be before you can ride one.
An electric bicycle, also known as an e-bike, powerbike or booster bike, is a bicycle with an integrated electric motor which can be used for propulsion. Many kinds of e-bikes are available worldwide, from e-bikes that only have a small motor to assist the rider's pedal-power (i.e., pedelecs) to somewhat more powerful e-bikes which tend closer to moped-style functionality: all, however, retain the ability to be pedalled by the rider and are therefore not electric motorcycles.
I have cerebral palsy and have used a powerchair since I was three.... About a year and a half ago I applied for a grant from the Challenged Athlete Foundation for a handcycle. While I was waiting for letters to go out I worked out at the gym. I was talking to my trainer about handcycles. I explained that because all of the weight was behind the drive wheel in...

On the road, it takes only a few turns of the pedals to activate the Vado’s motor and get it up to speed. In Turbo mode — the bike’s highest level of pedal-assist — the Vado reaches speeds of up to 28 miles per hour, after which the electric drive system automatically shuts off to conserve power (and abide by local law). A built-in LED readout on the handlebars allows riders to monitor battery life, check current speed, and track calories burned while also being able to glance at distance traveled. The Turbo Vado Mission Control app (iOS/Android) also connects to the bike via Bluetooth and allows riders to further tune their ride and adjust the bike’s settings.

Built by a company that’s made cycling equipment for more than four decades, the Vado feels more like a traditional bicycle than almost any other ebike. Its frame and components have been tuned to provide a familiar experience, making it easy for new and long-time cyclists to jump on and start pedaling. Specialized’s heritage shines through nicely, helping separate itself from the competition in an increasingly crowded ebike market.

This is the Freway Buffalo. It’s an ebike. I couldn’t say no to a free ebike to play around on, so we’re gonna have some fun with this thing for sure. It’s not a high end ebike like the Specialized Turbo Levo, but it only costs 1700 bucks whereas the Turbo Levo costs as much as a car. Although it’s marketed as a mountain bike, I’d put it in the commuter category. It’s got a big cushy seat, a really long stem, and those antler things on the handlebars. I’m not obligated to give you guys anything but the truth, so let’s put this thing together and take an objective look at it. First, let’s cruise on over to Freway’s website.

Because they’re electrically powered, e-bikes sit in a bit of a gray area between bicycles and motorcycles. While some states have enacted specific legislation to state where electric bikes can and can’t be ridden, in other states outdated laws mean they’re regulated as a moped or motor vehicle which can cause confusion over registration requirements, access to cycling infrastructure and how old you have to be before you can ride one.
In 2012, two e-bike advocates completed the first 4,000-mile (6,400 km) transcontinental e-bike tour from New York to San Francisco to advocate for e-bikes in major cities across the U.S.[81] Pedego Electric Bikes is the best selling brand in the U.S. Many e-bikes in the United States are standard bicycles converted using a kit. In general, the kits include the motor (the majority of which are hub motors built into the front or rear wheel), a speed controller, throttle (usually twist-grip or thumb throttle), necessary wiring and connectors, and a battery. Several U.S. companies offer conversion kits which also offer advanced lithium battery packs. Major manufacturers also offer complete e-bikes. Trek offers a line of e-bikes using the Bionx system in which the rider programs the controller to determine how much effort the motor will give in response to rider effort, from 25% up to 200% of the rider's power. This system ensures a minimum level of rider participation and is also used to comply with many European laws mandating partial human effort before the motor engages.
The Dail-E Grinder is perfectly designed to accompany you on your long commute. It's a top-of-the-line road bike in and of itself. BULLS has taken its premium frame and integrated it with the most advanced components from best names in the business.  It delivers an unbelievable 118 miles range under ideal conditions. This step-over speed-pedelec is a wonder of German engineering.
Best Buys are selected in the table below because they work well, come from solid companies and get high marks from users. Generally, buyers can opt to assemble the bike themselves, or pay an assembly fee to their local dealer or bike shop. (Assembly usually includes installing handlebar, pedals, seat and front wheel along with tuning and adjusting.)
A representative for Ancheer, a California-based e-bike company that sells some of the most affordable e-bikes in the US, expressed dismay over the tariffs in an interview with Electrek. Ancheer will regrettably be raising prices on their electric bicycles, but intends to try to absorb some of the cost to avoid passing on the entire 25% tariff to their customers.
Duke Eco-Marathon Team using an Electric Bike Technologies hub motor for the 2014 Shell Eco-marathon. The E-BikeKit motor provides optimal space saving because it does not require a chain (this makes it great for converting road bicycles to electric bicycles, which is what it is designed to do) but we hope to determine if it provides us with a better overall vehicle efficiency than our outboard motor.

In the 1890s, electric bicycles were documented within various U.S. patents. For example, on 31 December 1895, Ogden Bolton Jr. was granted U.S. Patent 552,271 for a battery-powered bicycle with "6-pole brush-and-commutator direct current (DC) hub motor mounted in the rear wheel". There were no gears and the motor could draw up to 100 amperes (A) from a 10-volt battery.[5]
Range is a key consideration with e-bikes, and is affected by factors such as motor efficiency, battery capacity, efficiency of the driving electronics, aerodynamics, hills and weight of the bike and rider.[36][37] Some manufacturers, such as the Canadian BionX or American Vintage Electric Bikes,[38] have the option of using regenerative braking, the motor acts as a generator to slow the bike down prior to the brake pads engaging.[39] This is useful for extending the range and the life of brake pads and wheel rims. There are also experiments using fuel cells. e.g. the PHB. Some experiments have also been undertaken with super capacitors to supplement or replace batteries for cars and some SUVS. E-bikes developed in Switzerland in the late 1980s for the Tour de Sol solar vehicle race came with solar charging stations but these were later fixed on roofs and connected so as to feed into the electric mains.[40] The bicycles were then charged from the mains, as is common today. While ebike batteries were produced mainly by bigger companies in past, many small to medium companies have started using innovative new methods for creating more durable batteries. State of the art, custom built automated precision CNC spot welding machines[41] created 18650 battery packs[42] are commonly used among Do-it-yourself ebike makers.

The new Electric Bike Kit Owners group on Facebook has taken off within the first week of its creation. Around 400 people have joined the online group with new members being added every day. E-bike riders are sharing the various ways that they have converted their bikes using the E-BikeKit Complete Electric Bike Conversion System. Each one of the electric bike conversions is more unique than the next. Some e-bike...
The time or distance an electric bike battery will run between chargings is impossible to judge with much accuracy. There are too many variables: terrain, speed, rider weight, bike load (shopping, kids, luggage), and more. However, we can make a few generalizations about an e-bike’s recharge time and overall working life. These generalizations should be used for comparison purposes only.

A representative for another large international bicycle company informed me that his company is now shifting its production of their 2019 electric bicycle models to two other Southeast Asian countries to avoid the import tariffs on Chinese e-bikes. The source spoke on condition of anonymity as he was not authorized to speak publicly on the matter.
You can also save money and make your own Day6 Patriot ebike as below only with one of several conversion kits such as Enduro Hub or Kinetic 8Fun MidDrive. You can start with your favotive comfy Day6 Bike Frame and save money by converting to electric yourself, or you can order a complete Day6 Patriot Electric bike of your choosing sent fully assembled.
If you are a regular bicyclist who wants to add some excitement to your rides or wants some help with those hills, a full sized electric bike is the way to go. If you are considering a bike as a means of transportation more than an outlet for amusement, then a smaller, folding electric bike is the convenient choice. In each category, consider the speed and range you want, as these factors impact price.

E-bikes use rechargeable batteries, electric motors and some form of control. Battery systems in use include sealed lead-acid (SLA), nickel-cadmium (NiCad), nickel-metal hydride (NiMH) or lithium-ion polymer (Li-ion). Batteries vary according to the voltage, total charge capacity (amp hours), weight, the number of charging cycles before performance degrades, and ability to handle over-voltage charging conditions. The energy costs of operating e-bikes are small, but there can be considerable battery replacement costs. The lifespan of a battery pack varies depending on the type of usage. Shallow discharge/recharge cycles will help extend the overall battery life.

Whether the terrain is flat or hilly impacts the distance you can travel, as does the weight of the bike, your own weight, the gearing available on the bike, and how much juice you give it. We suggest that a distance of 10 to 20 miles is a realistic expectation. Of course, if you're prepared to do at least some pedaling, you can extend that dramatically.


The Dew-E packs functionality and fun into a rather traditional and conservative package. Front and rear fenders, integrated Busch & Müller front and rear lights, and a built-in Abus wheel lock make this a very practical commuter bike. An 11-34t 9-speed cassette and 1.75-inch tires provide versatility: You’ll stay smooth over rough city streets and zip down gravel bike paths with confidence. Front and rear rack mounts also give you the chance to outfit this bike for carrying more cargo or supplies for a longer day on the bike. Whichever way you think you’ll be riding an e-bike, this bike deserves a second look.
