Gear Ratio Bicycle
A mobile drivetrain game where gear ratios are real: drag the chain between front and rear sprockets to keep cadence in a healthy band as the road gradient changes across twelve routes. Ratio, development in metres and speed update live, an honest gear chart marks unusable cross-chain combos, and fatigue rises when cadence strays. Finish with a route profile you can share.
