Document Type and Number:
WIPO Patent Application WO/2019/038463
Kind Code:
A3
Abstract:
The invention relates to an electric motor device for pedal assist bicycles, in which the battery (1) and the electric motor (2) control unit are integrated into the bicycle frame, while the electric motor (2) itself is integrated into the hub of the rear wheel. The invention also comprises: a control unit (5), which can be integrated into the bicycle frame or into the handlebar (34); a battery (1) charging outlet (10); a pedaling sensor (4) which can be integrated into the bicycle frame; and elements for controlling assist levels and the bicycle state. The main feature of the invention is the reduced size of the components thereof, as a result of which the device can be integrated with minimal impact on the design, weight or volume of the bicycle, since it is practically imperceptible. The invention allows the weight of the frame to be reduced, as well as protecting the battery (1) against impact and extending the service life of the battery (1).
