FIELD: machine building.
SUBSTANCE: group of inventions relates to the field of machine building, in particular to the motorized bicycles transmissions. Motorized bicycle transmission comprises gearbox configured to transmit the torque from the input shaft to the output shaft with one gear ratio, as well as to transmit the torque from the first output shaft to the input shaft with another gear ratio. Output shafts are connected by the stepping down mechanical transmission. Motorized bicycle transmission contains a reduction gear. Reduction gear contains the intermediate shaft connected to the output shaft by the stepping down mechanical transmission. Intermediate and output shafts are connected by the additional mechanical transmission. First or second disk member is mounted on its shaft on the first overrunning clutch, transmitting the torque only in the from the output shaft to the intermediate shaft direction. Third or fourth disk member is mounted on its shaft on the second overrunning clutch, transmitting the torque only in the from the intermediate shaft to the output shaft direction.
EFFECT: enabling the transmission installation simplification during the bicycle is motorization.
