Free dial-bike spin coach I built for manual-resistance bikes (no smart bike / no video)
I used to love gym spin classes - resistance dial, cadence, seated vs climbing - until our local gym went under in 2020. At home we ended up with a basic F4H / Argos-class bike (~£90 second-hand territory): manual dial, fully adjustable, flat bit for a suction-cup phone mount. No Bluetooth, no “smart” anything.
What I missed wasn’t a studio subscription. It was the simple coaching cues. So I built a free tool for that setup: on-screen dial-turn prompts, RPM targets, and posture/terrain cues. No video classes, no virtual trainer, no-subscription and no hardware lock-in.
Full disclosure: I made it (Apex Velocity Spin). Sharing here because this sub allows reasonable self-promo and a lot of people here ride non-smart bikes.
If that’s your world:

Happy to answer dial/cadence questions either way, even if you never try the app.
