The Spotter™ 600 from Bell® is a set of sturdy training wheels for children as they learn to balance and ride for the first time. Reinforced steel provides robust support for riders up to 80lbs. The training wheels have two modes - training mode and tricycle mode. In training mode, the wheels are designed to hover slightly above the ground and encourage rider balance by accommodating for tilt. In tricycle mode, the wheels remain planted on the ground to enhance rider stability. The training wheel brackets fit on wheels 20” and under. The Spotter™ 600 is a must-have for children learning to ride.
