Vehicle Specifications

A Schlumpf Drive is a two-speed planetary gear assembly for use on bicycles. It is distinct from other bicycle planetary gear assemblies in that it is located behind the chainring rather than in the rear hub. A push-button on each side of the axle allows the rider to switch between high and low ratios. These are operated by the rider's heel.
