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.

“Yamaha’s power assist motors provide the purest, most natural assist feel thanks in part to Yamaha’s Triple Sensor System that has been exclusively optimized for Yamaha’s U.S. power assist bikes. Through the Triple Sensor System, thousands of times per second, frictionless sensors measure the rider’s pedal-torque, bicycle speed, and crank arm cadence with tremendous precision.”
There are two main types of motor to suit different riding styles. The durable, "heavy duty" Direct-Drive motor, and the lightweight, efficient and fast "performance" geared motor. Electric Bike Motors, hub motors in particular, and electric bike batteries are what make electric bicycles go. Using a hand throttle you control the flow of electric current from the battery to the brushless motor. With an intelligent 20 Amp controller regulating the...
Fast and fun on the trail, the SDURO HardNine handles rough terrain with ease, while its large tires roll over most obstacles without missing a beat. The pedal assist makes for quick, energy-saving climbing and the bike descends surprisingly well, too. Its front suspension provides a nice level of cushion on bumpy trails and while we missed having a full-suspension on this model, that would have added additional weight and costs.
Cost: Good e-bikes are not cheap, and unlike most bikes, the costs associated with owning an e-bike don’t end when you hand over your credit card in exchange for a shiny new steed. The average cost of operating an electric bike is around $390 a year, including maintenance and charging. You’re also likely to need to change the batteries every 3-5 years so factor that into your costs.
The final thing I love about this the Riese & Müller Delite GT Touring is the plus size tires. If you’ve ever been on a bike for the majority of the day, you know that any little bit of cushioning can make all the difference. Riese & Müller have provided this extra cushion in their tires. These tires are also excellent for wet weather and some light off-roading if you want to take a shortcut.
The body is made from light and durable aluminum. The handlebar comes with simple controls to let you accelerate, brake, monitor battery life, operate headlights and of course…sound the horn. There’s even an USB point that will let you charge your iPhone or Android on the go. The bike can reach a top speed of 10mph. Feel the wind in your hair as you zoom up and down hills and past all that city traffic…
Known for not only their powerful line of mountain bikes and specialty bikes—cruisers to fat—Bulls also has a versatile line of urban models. The Cross E Wave comes as one of their more affordable options at roughly $2,800, but at 20 mph can still range for up to 134 in optimal conditions with everything you’d expect (fenders, lock, lights and adjustability). The entire family of Bulls e-bikes has specifications built for any scenario.
The complete integration of the Optibike is achieved from the ground up with a disign focused on high performance, safety, and ease of operation. Front and rear long travel suspension with disc brakes gives the rider confidence. The fully integrated package gives the utmost in convenience allowing the rider to ride on road, off road and the up or down the steepest hills. Optibike is in a class of its own. The Monocoque frame has sleek styling and a low center of gravity for stable handling. All electronics and long-running battery are safely housed inside the frame.
Rumour has it, the Gazelle is Europe’s most popular electric bike. We can see why. Right from the off, the bike oozes comfort. Its classic Dutch sit-up-and-beg geometry combined with pedal assist makes it a smooth, comfortable, almost effortless ride. The Bosch mid-mounted motor (in the bottom bracket shell) delivers impressive, even power with four settings selectable via the left-hand handlebar mounted button and displayed on the central Intuvia LCD display.
Electric trikes have also been produced that conform to the e-bike legislation. These have the benefit of additional low speed stability and are often favored by people with disabilities. Cargo carrying tricycles are also gaining acceptance, with a small but growing number of couriers using them for package deliveries in city centres.[51][52] Latest designs of these trikes resemble a cross-between a pedal cycle and a small van.[53][54]
Durability. You’re paying a lot of money and a costly investment that lasts for a short time is not worthwhile. The electric bike has more components than the common bike, adding the electric motor and the battery; more attention should be put in selection of the bike because of this. You don’t want your electric bike to turn into a regular bike in a short period.
You should be extra aware about your local regulations as in many countries an L1e-A certified bike needs to be registered and insured (be sure to consult your local laws and rules) and with registration comes the security that the bike can be tracked if it is stolen or misplaced. This approval that we have received is European Union wide and even those countries that are not part of the EU but rather EEA do adopt similar regulations in order to keep the market common but you will need to consult with your authorities. We will detail more about the registration process in an upcoming blog post but if you have any questions you can email us and we will respond in kind.
As electric bike options continue to expand, more brands are integrating the battery more seamlessly. That makes them look sleeker (and more like a real bike). Batteries are expensive, so make sure there's a good way lock the battery to your bike if you'll be keeping it outside. Overall weight is important. Some battery and motors can add 15 pounds or more to the bike. With assist, you won't feel that much when you're riding, but you will if you have to carry your bike up stairs or lift it onto a bike rack.
