The present invention provides a multi-speed transmission including: a driving shaft rotated by an input rotational force; a plurality of driving gears coupled to the driving shaft to be rotated by the rotation of the driving shaft; a plurality of transmission gears engaged with the driving gears; a transmission shaft including a plurality of pawls moved in and out of the outer circumferential surface, and coupled to the transmission gears, specifically, selectively coupled to at least a few of the transmission gears according to the in and out-movement of the pawls; a transmission control means for selectively controlling the in and out-movement of the pawls; a plurality of driven gears engaged with at least a few of the transmission gears; and a driven shaft coupled to the plurality of driven gears and transferring the rotational force to an object to be driven.

A bicycle grip with a tubular inner sleeve and a grip element surrounding the inner sleeve, and a clamping ring element connected to the bicycle grip for clamping the bicycle grip onto a handlebar, wherein a bushing is inserted into the hollow space of the handlebar on its face and which bushing has an internal thread into which an adjustment mechanism connected to the bicycle grip can be screwed for axially adjusting the handlebar width.

An adjustment device for tensioning a bicycle gearshift control cable. The adjustment device has opposed threaded elements and a compressible element, which is retained in position by a locking member and compressed between the threaded elements.

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.
