Great small 12v gear motor with face mount. I accidentally hit it with a hammer when equipped it, and put it under heavy load countless times. It worked well still, and really low noise!!

Lots of power and torque, powerful micro dc gear motor that upgraded my kids power wheels. At 12v they hit 344rpm. These are low noise. They work fine and don’t overheat, sturdy construction😀
