A.1.2. How to shift?

To activate a Schlumpf drive, there is no need for cables, derailleurs and the like.
Gears are changed by a simple push on a button, located at the end of the axle.

Push on the right side to shift up or down (depending which drive you use), push on the left side to shift back into direct drive.

If you use clic-in pedal systems or very small shoe size, use the kickplates (easy-shift levers), that allow to shift on the whole surface of the crankarm.

Every Schlumpf drive is available with two different activating forces: higher resistance for foot activation (standard bicycles), lower resistance for hand activation (hand bikes).
