Wheels. Riding with an improperly secured wheel can allow the wheel to wobble or fall off the vehicle, which can cause serious injury or death. It is very important that an operator know how to secure the wheels correctly, and how to apply the correct clamping force that safely secures the wheel. Ask an expert mechanic to advise you on correct wheel removal and installation in accordance with the wheel manufacturer’s specifications.
