Abstract: A chainless hybrid electric bicycle includes a bicycle body. A generator, a battery pack, a driving motor and a manual switch are mounted on the bicycle body. The generator is coaxially mounted with the pedal transmission unit, so that the generator generates an electric power when the rider works the pedals. The battery pack is electrically connected to the generator for storing the electric power generated by the generator. The driving motor drives the wheels of the bicycle body to run. The rider selects the electric power from the generator or the battery pack through the manual switch to drive the driving motor to run, which in turn drives the bicycle body to move forward. The chainless hybrid electric bicycle has the advantage of a hybrid power drive system, without using traditional mechanical transmission components such as chains and chainrings.

Abstract: A human-powered vehicle includes a crank axle, a first rotational body, a wheel, a second rotational body, a transmission body that transmits a driving force between the first rotational body and the second rotational body, a derailleur configured to operate the transmission body to change a transmission ratio, and a motor configured to drive the transmission body. A control device has an electronic controller configured to control the motor and drive the transmission body with the motor so as to change a rotational speed of the motor as the acceleration of the human-powered vehicle increases in a case where the derailleur has been actuated to change the transmission ratio and a predetermined condition related to pedaling is satisfied.
