A small motor with a plastic gear 120:1 and an offset shaft with a diameter of 2 mm. The recommended operating voltage of the motor is 4.5 V and at this voltage it reaches a speed of 120 RPM and a maximum torque of 1.4 kg*cm, consuming a current from 0.08 A to 0.8 A. The motor uses a shaft with grooves compatible with adapters for LEGO wheels.
Suitable mounting brackets in low and high versions are available for the motors.

Our offer includes a number of controllers that perfectly cooperate with the presented engines.
