Zusammenfassung:	The bicycle has a frame 1, a steerable front wheel 7 and the driven rear wheel 70 mounted by a suspension assembly 30 for articulation with respect to the frame 1. Drive to rear wheel sprockets 71 is performed by chain wheels 14 - 16 through the intermediary of an endless chain 75 having a lower path length 91 and an upper path length 92; to provide a substantially constant upper path length 92, an idler wheel 100 is located above an outer periphery of the chain wheels 14 - 16 and a pivot point 45 of the suspension is, preferably, substantially in a horizontal plane of the upper path length 92. The idler wheel 100 is moved on a support axle to move the chain 75 between the wheels 14-16.
