The bicycle (10) has a chain deflector positioned between the driving pinion (34) and the driven pinion (42) such that the distance between the point at which the upper chain segment is currently engaged with the driven pinion of the rear wheel and the point of the chain deflector about which the chain (40) is substantially pivoted when the rear wheel is deflected changes slightly. The crank arms (38) of the bottom bracket (36) rotate by a maximum permissible angle relative to the non-deflected position of the rear wheel when the spring is deflected in and out.
