This article lists notable electric bicycle brands and manufacturers including electric unicycles. Many bicycle brands do not manufacture their own product, but rather import and re-brand bikes manufactured by others, sometimes designing the bike, specifying the equipment, and providing quality control.
A 48 V system can provide more power, improve energy recuperation, [7] and allow up to an 85% decrease in cable mass. [10]12-volt systems can provide only 3.5 kilowatts, while a 48 V power could achieve 15 to 20 kW or even 50 kW. 48 volts is below the level that is considered safe in dry conditions without special protective measures.

Converting a non-electric bicycle to its electric equivalent can be complicated but numerous 'replace a wheel' solutions are now available on the market. [44] An Electric Pusher Trailer is an e-bike design which incorporates a motor and battery into a trailer that pushes any bicycle. One such trailer is the two-wheeled Ridekick.

Bicycle drivetrain systems are used to transmit power on bicycles, tricycles, quadracycles, unicycles, or other human-powered vehicles from the riders to the drive wheels.
Raleigh SC30 converted to an electric bicycle with an aftermarket electric conversion hub motor kit. A wheel hub motor, hub motor, or in-wheel motor is a motor that is incorporated into the hub of the wheel. Wheel-hub motors are commonly found on electric bicycles.
A development of the motorized bicycle is the moped, which commonly has only a vestigial pedal drive fitted primarily to satisfy legal requirements, and suitable only for starting the engine or for emergency use. The alternate design philosophy to the moped is the so-called motor-assist or pedal-assist bicycle. These machines utilize the pedals ...
The Copenhagen Wheel contained a custom brushless motor, advanced sensors, control systems, and a lithium-ion battery, enclosed within the rear wheel hub. [4] The control system interfaced with a range of sensors measuring torque, power, cadence, pedal position, and acceleration to monitor a rider's effort when pedaling. The Wheel responded to ...
