Stutterbump PeeWee Training Wheels feature 40mm of adjustment. So as the beginner advances you only need to raise the wheel off the ground to observe if the rider is able to ride unassisted. If so the training wheels can be removed, if not they can be lowered back down again.
Stutterbump recommend no more than 30kg of weight be placed on the motorcycle once the Training Wheels are fitted. They are a training device, unsuitable for dinking. When starting the mini motorcycle we recommend using the centre stand to refrain from applying undue stress on the Training Wheel by leaning the motorcycle over.
