摘要

The assembly has a crank (2) of 24 centimeter whose front end supports a pedal (3) and the rear end slides horizontally in a horizontal slider shoe (5) fixed to the frame (6) of a bicycle. The crank is fixed at approximately one third of its length on a crank (1) of the pedal. The rotation of fixing point of the crank and horizontal sliding of the rear end are combined mechanically to give a nonsymmetrical trajectory to the pedal.
