Designed for young riders, the Wald 1216 Bicycle Training Wheels mounts to most bicycles with wheels measuring 12 to 16 inches in diameter. These training wheels provide safety during wobbly rides thanks to their all-steel construction. For added stability and safety, the tire is mounted directly to the wheel. The included steel brackets provide multiple height options for mounting the wheels while brace arms provide additional stability. With new frame adapters for improved installation, these training wheels support riders up to 75 pounds.
