MOTOR-ASSISTED BICYCLE

Abstract [Object] To provided a motor-assisted bicycle which allows use a bicycle frame used popularly and effectively utilizes the space rearwardly of a seat post. [Solving Means] A motor-assisted bicycle 1 includes a body frame 2, a front wheel WF, a rear fork 9, a rear wheel WR, a crankshaft 17, a chain 22 and an assisting power unit 16. The front wheel WF is rotatably supported on a front fork 7 at a front wheel WF is rotatably supported on a front fork 7 at a front potion of the body frame 2 for steering operation by a steering handle bar 8. The rear fork 9 includes a pair of left and right support rear fork 9 includes pair of left and right support members 9L and 9R extending rearwardly from wheel WR is rotatably supported on the rear fork 9 between rear ends of the support members 9L and 9R. The crankshaft 17 is rotatably mounted on the body frame 2. The chain 22 transmits pedaling torque applied to the crankshaft 17 to the rear wheel WR. The assisting power unit 16 assists the pedaling torque to apply assisting torque to the chain 22. In the motor-assisted bicycle 1, the assisting power unit 16 is disposed below the rear frame 9. Further, a projection 54 of an accommodation mamber 50 which covers a secondary speed reducing driven gear 63 which composes a speed reducing gear train 56 of the assisting power unit 16 is inserted below to and disposed at a position between the pair of left and right support members 9L and 9R.
