The invention relates to a drive device for a two-wheeled or a three-wheeled vehicle. The inventive device comprises a rotary drive which drives a hydraulic piston pump that drives a hydraulic piston engine by means of a hydraulic line connection. Said engine is provided with a main drive pinion for driving a wheel. The inventive device is characterised by a transmission (10, 12, 74) having a speed increasing ratio between the rotary drive (4) and the piston pump (14, 76). |
