Starting aid for vehicles e.g. bicycles, wheelchairs has multilevel gear, electric servomotor for transmission change, accumulator as energy storage and energy supplier for servomotor and a switch is provided to activate starting aid
Starting aid has multilevel gear (1), electric servomotor (6) for changing gear transmission ratio and accumulator (3) as energy storage and energy supplier for servomotor. The available active tread force is recorded by sensors e.g. in area of pedal axle. A control unit (4) steplessly changes gear transmission ratio using servomotor depending on active tread force and desired tread output. The switch (7) is provided through which the gear transmission ratio is brought into a definite starting position. A switch (8) is provided through which the starting aid is activated.
