ABSTRACT:
A pedaling assistance device for a light vehicle, in particular a bicycle, equipped with pedals and a ratio-changing transmission, this device comprising a heat engine (1; 101; 201) equipped with a reducing gear mechanically coupled with an element receiving muscular pedaling power from a user of the light vehicle, the mechanical coupling being effected upstream of said ratio-changing transmission so that the heat engine benefits from said changes of ratio, wherein the assistance device comprises a torque limiter (6; 106; 206), placed on the kinematics of the reducing gear of the heat engine between said heat engine and the mechanical coupling.
