Abstract
Abstract A side warning device for cycles, such as bicycles and motorcycles, is attached to the axle of the cycle, so that the warning device is visible from the side of the cycle. Warning devices can be coupled on both sides of the front axle and on both sides of the rear axle, in the case of bicycles, to provide for maximum side visibility. In the case of motorcycles having obstructed rear axles, the warning device can be coupled on both sides of the front axle. The warning device can be a light reflecting medium.
