Abstract
An electronically controlled bicycle suspension apparatus includes a suspension system, a sensor such as a biaxial accelerometer, an electronics module, at least one actuator and at least one battery for powering the sensor, electronics module and actuator. The suspension system mounted to and between first and second parts of a bicycle movable relative to one another in response to a shock applied to the bicycle, includes a cylinder having telescoping members defining an interior cavity and respectively connected to the first and second relative movable bicycle parts and movable toward and away from one another between predetermined limits, an extendable and contractible spring disposed within the interior cavity being biased to force the telescoping members away from one another, a fluid contained in the interior cavity and a partition fixed across the interior cavity inside of a telescoping members to divide the interior cavity into separate chambers. The partition defines at least one orifice having a predetermined size for controlling a rate of flow of the fluid between the chambers so as to control contraction of the spring and thereby control movement of the telescoping memb…
