Lego Technic 4x4

LEGO’s Technic differentials are as beautifully simple and effective as the real-world versions fitted to every vehicle’s driven axel/s. But they’re rubbish off road.

This means you can go around corners when on the road, then lock the diffs for off-road and keep all your wheels turning when things get slippery. Want to see how it works?
