Presented herein is a bottom bracket gearshift (1) of an electric bicycle (64) with an auxiliary drive (22), in particular in the form of a central motor. The bottom bracket gearshift (1) has a shift gearbox (4). In order to make the shift gearbox as small and light as possible, an input stage (14) is arranged at the transmission input (10) of the shift gearbox (4). The input stage (14) may be arranged between a bottom bracket shaft (6) and/or the auxiliary drive (22) and is configured as a transmission into high-speed.

A vehicle is powered and steered by a rider's arm. The vehicle may be a cycle or a tricycle Propulsion occurs in response to the rider pushing and pulling on the handlebar along a fore-and-aft direction. The propulsion mechanism resists or prevents the cycle from unintentionally rolling in reverse. Steering occurs in response to the rider pushing the handlebar to the right or left. The steering mechanism responds the same no matter where the propulsion system is in its range of motion and can provide approximately a 5-foot turning radius for a rider steering input, by moving the handlebar approximately 1 foot right or left of center steer, while maintaining front wheel alignment. A shifting mechanism provides multiple settings between lower gears for hills and higher gears for speed.

Gear arrangement for a vehicle, having an input shaft, a layshaft, an output shaft connected to a drive wheel of the vehicle, a plurality of shiftable first gear wheel sets which connect the input shaft and the layshaft and which are each associated with at least one gear stage, and a machine gear connected to one of the shafts and into which the drive torque of an electric machine can be introduced. The first gear wheel sets form a first part-gear mechanism, wherein at least one second shiftable gear wheel set connects the layshaft and the output shaft and forms a second part-gear mechanism, wherein the at least one second gear wheel set is associated with at least one gear stage and wherein the machine gear is arranged in an axial direction between the first part-gear mechanism and the second part-gear mechanism.
