Bicycle equipped with drive assist |
摘要 |
<p>The bicycle comprises a drive assist attached to a driving wheel, a driving power transmission means (20) attached between a sprocket (26) and a rear wheel, a pair of pedal levers (22R), a crank lever (30R) for transmitting a rotation force of the pedal lever to the sprocket and a sliding portion (40R) serving as a swing fulcrum of the pedal lever. A slide pin (42R) at one end of the pedal lever slides within the slide portion in accordance with the rotation of the pedal lever to transmit a rotation force generated by the rotation of the pedal lever to the rear wheel through the sprocket. A pedaling force sensor (52) is attached to a part of the pedal lever which makes nearly reciprocating motion, and the output from the sensor is supplied through a signal wire (54) or the like to a controller which controls the drive-assist. <IMAGE></p> |
