A drive system (3) for a human powered vehicle. The drive system (3) includes at least one input member (31), a transmission system (21) arranged to convert movement of the input member (31) to rotation of an output member (83), and a lock mechanism (123) including at least one drive member (133) for selectively locking a drive wheel (11,13) to rotation of the output member (83) for rotation therewith. The drive member is arranged for movement from a first operational position in which the drive wheel is not locked to the output member to a second operational position in which the drive wheel is locked to the output member, and back to the first operational position, under the control of a user of the vehicle. The drive system allows the user to choose between propelling the vehicle using the drive system or disengaging the drive system from the drive wheel and propelling the vehicle by some other means, for example by wheel rims.
A drive system for a human powered vehicle including at least one input member, a transmission system arranged to convert movement of the input member to rotation of an output member, and a lock mechanism including at least one drive member for selectively locking a drive wheel to the output member for rotation therewith.
A transmission system for a human powered vehicle including an input member, first and second gearing elements, a clutch and a flexible drive member for transmitting drive between the first and second gearing elements, wherein the input member is arranged to drive the first gearing element, the output member is arranged to be driven by the second gearing element via the clutch, and the clutch includes a plurality of roller elements arranged to drive the output member when the input member is drivingly actuated by a user and to allow the output member to rotate relative to the roller elements when the input member is not drivingly actuated.
A human powered vehicle including a frame and a backrest pivotally attached thereto and lock means for locking the angular position of the backrest relative to the frame, wherein the angle of the backrest relative to the frame is continuously adjustable through a range of values.
