A bicycle has an auxiliary engine, a wheel, and a clutch mechanism disposed between the auxiliary engine and the wheel for enabling and disabling power transmission between the auxiliary engine and the wheel to select one of a pedal-propelled drive mode and an engine-propelled drive mode of the bicycle. The bicycle includes a clutch lever for connecting and disconnecting the clutch mechanism, a throttle lever for controlling a throttle valve of the engine, a switching mechanism for connecting the clutch mechanism in coaction with the throttle lever when the clutch mechanism is disconnected, and an engine starting circuit closable and openable in response to connection and disconnection of the clutch mechanism. The clutch mechanism can be connected in response to operation of the throttle lever, the engine can be started when the clutch mechanism is connected, and the engine can be rendered inoperative in response to operation of the clutch lever.

Bicycle with an auxiliary engine

A parking locking system for an articulated or swing-type tricycle. A parking lever mounted to the handlebars of the steerable wheel actuates a cable and a rod. The rod engages a spring loaded slideable pin member into a hole in a plate fixed to the front frame of the steerable wheel. If the pin is not aligned with one of the holes in the plate, the spring will deform and the pin will slide relative to the rod. Upon further rotation of the front handlebars to a position where the pin member is aligned with a hole, the compression in the spring will cause the pin to interengage with the fixed plate thus locking the front steering wheel. The actuation of the cable interengages locking arms with a plate attached to the front of the swing shaft and with a parking gear in the drive train, respectively. A spring-loaded lever resisting interengagement of the locking arms is used to create tension in the cable and retract the locking arms when the parking lever is deactivated.
