摘要： The invention relates to a device (30) for the propulsion and eccentric braking of a vehicle having a pedal drive, in particular a bicycle (20), comprising: A) a first shaft (4) having a longitudinal axis (31) and drive means (28) comprising one or a plurality of chain wheels (32), belt pulleys or elements of a cardan drive; B) a second shaft (11) which is designed as a hollow shaft arranged concentrically about the first shaft (4) and can be mounted into a rear wheel (33) of a vehicle having a pedal drive, in particular a bicycle (20); C) a freewheel clutch (3) which is mounted between the first shaft (4) and the drive means (28); D) an optionally engageable and disengageable reverse gear mechanism (23) which is mounted between the first and the second shaft (4, 11), wherein an opposite rotational direction is generated between the first and the second shaft (4, 11) when the reverse gear mechanism (23) is in the engaged state and a rotation in the same direction is generated between the first and the second shaft (4, 11) when the reverse gear mechanism (23) is in the disengaged state; and E) a shifting device (14) for engaging and disengaging the reverse gear mechanism (23), wherein F) the first and the second shaft (4, 11) are connected to each other in a torsionally rigid manner when the reverse gear mechanism (23) is in the engaged and disengaged state; and G) the freewheel clutch (3) which, as viewed from the drive means (28), prevents a rotation of the drive means (28) relative to the first shaft (4) in the clockwise direction and is in the freewheeling state when the drive means (28) rotate in the counter-clockwise direction relative to the first shaft (4).
