It’s a gear-driven rolling wonder! Assemble and then let it roll! The entire thing is designed to mimic a steam engine, with an open design so you can see the inner workings. Powered by rubber bands, it’s fascinating to watch!
- Run with wheels locked until the rubber band’s stored energy is depleted (about 7 feet max distance, depending on terrain)
- Unlock the wheels and it chugs ahead, the wheels locking when when the rubber band motor stops. After that, it rolls freely until it meets an obstacle
- Wheel measures about 6.5” in diameter.
UGears models are made from laser cut high quality plywoods. All the gears and mechanisms are designed to snap together without needing additional tools or glue.
Note: It’s helpful to have a craft knife handy in case pieces do not release easily from the surrounding wood.
