A computer controlled suspension system is provided for a bicycle, which can effectively absorb shock and provide stability on rough surfaces regardless of the speed of the vehicle. The suspension system has a control unit, a front suspension, a rear suspension, a front wheel terrain sensor, and a rear controller. The rear suspension is selectively adjustable by the control unit to change stiffness of the rear suspension. When the front suspension hits a bump or a depression in the surface of the ground, a signal is sent to the rear controller so that the rear suspension can react appropriately. In one embodiment, a pedaling torque sensor is operatively coupled to the control unit to input a signal that is indicative of pedaling force, and the rear controller adjusts stiffness of the rear suspension in response to the pedaling force via the control unit. In another embodiment, one or more gear position sensors are operatively coupled to the control unit to input a signal that is indicative of gear position, and the rear controller adjusts stiffness of the rear suspension in response to the gear position force via the control unit. A locking mechanism is provided to operatively coupled to selectively lock the rear suspension in a compressed condition. The front and rear suspension preferably uses at least cylinder with a coil spring and a compressible material located between individual turns of the coil spring.
