A control system is operable to selectably activate shock damping devices associated
with a bicycle so as to eliminate bobbing encountered under extreme pedaling conditions.
The system includes a crank axle torque detector which operates to detect a level
of torque applied to a crank axle and provide a control signal corresponding to
the level of torque. A shock damping device is coupled to the frame of the cycle,
and functions to absorb and dampen mechanical shocks communicated to the frame.
The shock damping device includes an activator for controlling its damping function.
The activator is operable to receive the control signal from the crank axle torque
detector and control the shock damping device in response thereto. The control
signal may be an electrical or a mechanical signal.
