No smart trainer. No subscription. Just your webcam.
CycleRun transforms every home trainer workout into an immersive experience. Your webcam detects your movement — no smart trainer, no sensors, no subscription. Perfect for spinning bikes, ergometers, old home trainers and soon treadmills too.
AI-powered motion detection measures your cadence in real-time — right in your browser.
Realistic acceleration, inertia and gear shifting. Feels like riding outdoors.
Use your own POV videos or browse featured routes. Your pace controls the speed.
Yes, CycleRun is a community project and completely free. No subscription, no premium version, no hidden costs. You just need a webcam and a browser.
CycleRun works with any home trainer where legs move visibly: spinning bikes, ergometers, old home trainers, indoor bikes — even devices without Bluetooth or smart features. Running mode for treadmills is in development.
Your webcam detects your leg movement using AI-powered image analysis. You place detection zones over your knees or pedals — the software automatically recognizes your cadence. All processing runs locally in your browser.
Zwift requires a smart trainer (from €300) and costs €17.99/month. Rouvy is similar. CycleRun is free and only uses your webcam — ideal if you want to upgrade your existing home trainer without investing in expensive hardware.
No. All image processing happens exclusively locally in your browser. No images or videos are transmitted to our servers. Your privacy matters to us.
Yes! Whether your ergometer is 5 or 25 years old — as long as your legs move, CycleRun detects the motion. No smart trainer or sensors needed.
We need access to your camera and some info for the physics calculation.
For motion detection
Choose the perspective of your webcam.
Side view recommended — knee movement is more clearly visible.
Position the zones over your knees or pedals. They flash when motion is detected.
Test your setup with a few pedal strokes. The display should respond to your movement.
