Abstract: The present invention provides a scooter with driving mechanism comprising a scooter assembly and at least a driving mechanism, wherein the scooter assembly has a treadle and a rear wheel; the driving mechanism comprises a reset device and a transmission device, which has an irreversible transmission unit and a passively driven gear, wherein the passively driven gear is driven by the driving gear in meshed manner to drive the irreversible transmission unit in relay way, the irreversible transmission unit, which is connected to the rear wheel, is served to drive the rear wheel to rotate in single direction. Thus, by means of the treading and releasing actions with the treadle, the scooter can be driven smoothly with benefits in not only the risk of tumbling down accident being avoided but also the effects in energy-saving and environmental protection being achieved.

Abstract: A bicycle seat post assembly includes an outer tube with an inner tube movably inserted thereto, the top end of the inner tube is connected with a seat. The inner tube has a passage defined longitudinally therethrough and a valve is connected to the lower end of the inner tube. A connection member is connected to the lower end of the outer tube and a seal member or an output tube is selectably connected to the connection member. The seal member seals the lower end of the outer tube to form a interior space in the outer tube filled with pressurized air when the bicycle seat assembly is a shock absorbing seat post assembly. The output tube is connected to the connection member to communicate with the longitudinal passage of the outer tube when the seat post assembly is used as a tire pump by reciprocating the inner tube.
