A bicycle in which a drive wheel is driven through a pedal-operated drive. A clutch is provided for transmitting the drive to the bicycle drive wheel, and this clutch is constructed so that it will respond only to operation of the drive in the direction which will propel the bicycle forwardly for assuming an engaged position to transmit motion to the drive wheel. Under any other conditions such as when the drive is operated in a reverse direction or when the drive is stationary the drive wheel is free to turn either in a forward or in reverse direction so that, for example, it is possible to freely roll the bicycle rearwardly when the drive is not operating or is operated in a reverse direction. This reverse direction can occur when the pedals are turned rearwardly, and a brake structure brakes the movement of the bicycle in response to such rearward turning of the bicycle pedals.
