Wald training wheels provide safety during wobbly rides thanks to all-steel construction. The tire is mounted directly to the wheel for a secure fit. The steel brackets provide multiple height options for mounting the wheels, while brace arms provide additional stability. Please note: Wald training wheels are designed to be training aids used for a temporary period of time. If the rider has special needs or exceeds the designated weight limits, we cannot recommend our products for their use. In order for Wald training wheels to fit your bicycle, there must be at least 3/8" of axle outside the axle nut on both sides of the rear wheel. Wald training wheels are designed exclusively for single speed bicycles. They are not designed for multi-speed bicycles
