Abstract

An electric-motor-assisted bicycle includes a vehicle-body frame and a drive unit including two couplers. The vehicle-body frame includes a bracket and a pair of chain stays. The drive unit is attached to the bracket. Each of the chain stays is attached to a position on the bracket rearward of a crank axle in the front/rear direction of the bicycle. One coupler is forward of the crank axle in the front/rear direction of the bicycle. The other coupler is rearward of the crank axle in the front/rear direction of the bicycle. At least one of a region of the bracket to which the chain stay is attached and a region of the bracket to which the other coupler is attached does not overlap a line segment connecting a shaft center of the axle of the rear wheel to a shaft center of the crank axle.
