A VéloSoleX motorized bicycle. A motorized bicycle is a bicycle with an motor or engine and transmission used either to power the vehicle unassisted, or to assist with pedalling. Since it sometimes retains both pedals and a discrete connected drive for rider-powered propulsion, the motorized bicycle is in technical terms a true bicycle, albeit ...
A chain drive and rear derailleur gear change, the most popular system in use today A shaft-drive with crankset and rear gear hub. 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.
In 1948, Whizzer sold its first pre-assembled motorized bicycle, the "Pacemaker", for US$199.50 (equivalent to $2,500 in 2023).

Ixion engine on a Komet motorised bicycle, ca. 1902. This system is used, for example, to drive the spools in some tape recorders.In a typical configuration, one of the cylinders is the axle of an electric motor, say 1 mm in diameter, while the other is a disk with a hard rubber rim, say 50 mm in diameter, yielding a 1:50 mechanical advantage.

On traditional bikes, the front derailleur is problematic because the chain can be under tension and has to make a large vertical jump between chainrings. The electronic system's controlled motion overcomes these problems. The Di2 can also trim the front derailleur to eliminate chain rub and calibrate itself to adjust for wear and tear. [16]
A motorized bicycle provides motor assistance. (Not to be confused with motorcycles or electric motorcycles and scooters.) An electric bicycle, also called an e-bike, is primarily propelled by the rider, but with assistance provided by an electric motor; usually located in the hub of the front or rear wheel. The electric motor is powered by a ...
