Chained Bike Racing 3D

The chain is the whole game. Two bikes move as one unstable object, and the moment one falls behind or drifts wide, the other is pulled off its line. Riding well means keeping both machines at the same speed rather than making one of them fast.

Stunt sections turn this into a genuine puzzle: a ramp that is trivial for a single bike becomes a question of whether the second one will land at the same moment.

It is unusual, awkward in a good way, and short enough not to outstay the joke.

1. Keep both bikes at a matched speed.
2. Take ramps square so the chain does not twist.
3. Slow down before the trailing bike catches up.
4. Reach the finish with both machines upright.
