This motor is a low cost drive system for robots and other robotics applications. The hobby DC motor has a wide operating voltage and the two output shafts allow for wheel and encoder mounting.

These gearboxes fit nicely with our plastic & rubber wheels and we also stock plastic gearmotor brackets to fit.
