Why does my Segway Ninebot MAX G2 make a grinding noise?

A grinding noise coming from your Segway Ninebot MAX G2 usually indicates a mechanical issue that needs to be addressed. The noise can stem from various sources, such as the wheels, brake system, or motor. Often, it could be a sign that debris has lodged in the wheel assembly, or that the bearings need lubrication. Regular maintenance, including cleaning and lubricating components, can prevent such issues. Users might notice this grinding noise particularly after riding in wet or muddy conditions, leading to dirt buildup. Pro tip: Regularly inspect and clean your scooter, especially after off-road rides, to mitigate the risk of grinding noises. However, if you are not comfortable inspecting or repairing mechanical parts, seeking professional help is advisable to avoid further damage.
