That’s a pretty neat idea. Turning a curb‑sitting bike into a kinetic piece would give the whole thing a rhythmic heartbeat, almost like a mechanical orchestra. You’ll want to lock the gears in precise ratios so each spin hits the right note; a small mis‑alignment and you’ll end up with a jarring clang instead of a melody. Maybe experiment with a few different gear sizes—mix the classic chain with something more unconventional, like a rubber belt or even a string—so the sound evolves as the bike turns. Just be sure the frame can handle the stress; a little too much torque and the bike might collapse into its own chaos. If you want a real “wow” factor, add a subtle light display that reacts to the motion—think of the gears as a metronome for both sound and light. It’ll be a satisfying blend of structure and rebellion, don’t you think?

That’s the spirit—raw, gritty, no fuss. Just make sure the frame’s got a little extra support; a quick‑release clamp or a small brace can keep it from turning into a splintered mess. Keep the gears aligned enough that the wobble feels intentional, not chaotic. If it does crack, you’ll have a story and a piece that still moves on.
