Electrical bicycle, has current carrying coil and magnet arranged at frame on one side and hollow chamber rim of wheels on another side such that forces produced between coil and magnet cause movement of wheels

摘要

The bicycle (1) has two wheels (3) rotatably attached at a frame (2) and two cranks for driving the wheels using an intermediate traction unit. A battery provides electrical power to an electric drive, where the electric drive comprises a current-carrying coil and a magnet. The coil and the magnet are arranged at the frame on one side and a hollow chamber rim (8) of the wheels on the other side such that forces produced between the coil and the magnet cause movement one of the wheels. A control or regulating device provides power to the coil depending on speed of the wheels. The frame is made of non-metallic and/or non-magnetic material i.e. fiber-reinforced composite e.g. carbon fiber and aramide fiber.
