Abstract: Brake means for a bicycle having a recessed portion provided on either one of the contact portions between a wheel rim and a brake rubber piece and extending in the direction of the periphery of said rim, the other of the contact portions being provided with at least one projection adapted to be brought into engagement with said recess, the arrangement being such that a wedging action is created when the recess and the projection are pressed with each other to produce a strong braking force. Further, the wheel rim may be provided on its recess or projection with uneveness across the recess or projection so as to facilitate draining of water and prevent the braking effect from being reduced in a rainy weather.
