Electric motor device for pedal assist bicycles

An electric motor device for pedal assist bicycles, comprising:

• an electric motor having a hub shape, the electric motor connectable to a rim of a rear wheel of a bicycle, the electric motor including at least one free wheel rigidly connectable to at least one transmission gear wheel of the bicycle;
• a pedaling sensorconnectable to a hanger of a frame of the bicycle, the hanger disposed in an anchoring zone of a rear hub of the frame of the bicycle;
• a charging outlet;
• a control unitconnectable to the frame of the bicycle and operable via a user for actuation and control;
• a block insertable into an oblique main tube ofthe a frame of the bicycle;
• wherein the block includes:
• a battery operatively connected to the charging outlet such that the battery is rechargeable via the charging outlet, the battery configured to actuate the electric motor;
• a motor controller configured to control a plurality of operating parameters of the electric motor;
• a battery manager configured to manage the battery;
• the battery manager, the battery, and the motor controller connected directly togetherin parallel;
• a plurality of first cables connecting the block to the electric motor, the charging outlet, and the pedaling sensor;
