Abstract
A shock absorber for use with a cycle comprises elongated first and second tubular members and a biasing assembly. The first tubular member is associated with the cycle's frame and has a longitudinal axis. The second tubular member has a lower end portion adapted for connection to foot supports and an opposite upper end portion for connection to the cycle's seat assembly such that the foot supports and the seat assembly are interconnected for common movement. The second tubular member is slidably disposed with respect to the first tubular member for movement along the longitudinal axis away from an initial position as determined by a pre-impact condition. The biasing assembly is coupled between the tubular members so that movement of the second tubular member in a first direction away from the initial position is resisted by the biasing assembly, which responds with a restorative force to urge the second tubular member in a second direction toward the initial position thereby cushioning the seat and drive assemblies relative to impacts during operation. A methodology for cushioning impacts during operation is also disclosed.
