Zusammenfassung:	Bicycle (10) comprises a foot drive on the rear wheel (14) and an additional hand drive on the front wheel (38) fixed to the rotating front fork (32) and the fork tube. A forward-facing horizontal operating lever (44) with a horizontally rotating axle is mounted on the fork tube and/or the steering bar (34). The length of the operating lever controlling the front wheel is individually adjusted with two handles (48). A connecting rod (60) is hinged to the operating lever via an upper floating axle (58) at a distance from the free lever end. The connecting rod is connected to a front drive wheel (64) held on the front wheel fork. This front drive wheel is connected in a torque-resistant manner to a free-wheeling hub of the front wheel via a continuous flexible drive organ.
