Recumbent cycle

摘要

Recumbent cycle (12) is supported by a pair of forward steerable wheels (16) and a single rear drivewheel (18) mounted on rear end portion of a frame structure (14) by a hub assembly (50) having an integral transmission and brake. A pair of side-mounted gimbal assemblies (170L, 170R) may be conveniently tilted laterally to steer wheels (16) in the same corresponding direction. The gimbal assemblies (170L, 170R) may be individually or in unison tilted in the forward direction to actuate the brake of hub assembly (50). Frame structure (14) includes a forward beam (34) telescopically engaged within a main beam (32) to vary the distance between a crank assembly (28) and a seat (20) to accommodate riders of different sizes.
