Schematic diagram pedal kickback
The aim of our optimization is to reduce the fundamental pedal kickback of all multi-link rear suspension systems by keeping the horizontal change in length of the rear suspension over the compression travel as low as possible. The pedal kickback describes the change in length of the chainstay over the spring extension phase and is determined by the direct distance between bottom bracket and rear wheel axle. During extension, the distance between bottom bracket and rear wheel axle increases, which results in the change in chain length pulling the crank backwards against the pedalling movement. This may result in a loss of ride stability if the crank kicks back in the top dead centre and accidentally “hits a void” in the direction opposite to pedalling.
