The invention relates to a bicycle having a bicycle seat arrangement (11) which is rotatable with respect to the bicycle and connected to same, a bicycle drive which drives a rear wheel (3) and has a bottom bracket (5) and two pedals (4) which are alternately moved downwards, and a steering column (9) which is connected at the top to a handlebar (10) and at the bottom to a front wheel fork (8). The invention is characterised in that the rotational movement of the bicycle seat arrangement (11), viewed in direction of travel, is possible to the left and right side and is independent of the steering movement of the bicycle, wherein the axis of rotation (IIa) of the bicycle seat arrangement (11), viewed in direction of travel, is arranged in front of the axle of the bottom bracket (5) and wherein the sitting surface of the bicycle seat (14) is arranged, viewed in direction of travel, behind the axle of the bottom bracket (5). The rotatable bicycle seat arrangement makes an upright riding position possible by diverting the downward-moving leg of the rider through a rotational movement. Simultaneously it supports the hip side of the other leg. The rider is also supported by the bicycle seat, even in an upright riding position. |
