Description

Drive without batteries

Instead of electricity, a spring supplies the energy: you wind up the motor, and it passes the force on to your model through an axle. The 41 pieces come in 22 types, including gears and housing parts for the mechanism. The set belongs to the Technic supplemental sets and is aimed at anyone who wants to power their own vehicles.

Built into your own models

The motor is not meant for one particular model but for your own constructions: a car with a wind-up drive or a small walking mechanism goes together quickly. Black, blue, light grey and white give it a technical look. The parts list on this page shows every component, and the "What can I build?" tool checks which further models your collection allows.
