Indoor cycling, real physics
Ride a branching neon lattice, defend a power grid with your legs, or spin an honest Zone 2 — every mode on the same physics you can check yourself.
Pixel Watts turns your smart trainer into an arcade. You pedal, the bike moves — and every metre of it is computed from real cycling physics you can inspect for yourself.
RIDE WHATEVER YOU'RE IN THE MOOD FOR
OutRide Arcade — a branching neon track network. Pick your line at every fork; shorter and brutal, or longer and tactical. Every line is colour-coded by difficulty, so you know what you're in for before you commit. Bronze, Silver and Gold on every stage, scaled to your FTP.
Watt Defense — your legs are the power grid. Every watt you pedal charges and fires the towers; ease off and the defence weakens with you. Push too hard for too long and the towers overheat. Thirteen worlds, a weekly boss, and no cheat button anywhere.
Story Rides — a narrative gives training a reason from the inside. The story is fiction; the watt targets underneath it are not. A new curated story every week.
Zone 2 Autopilot — ride your target watts while the trainer also regulates by heart rate, so you stay inside the optimal aerobic window instead of drifting out of it.
Pulse Lock — name a heart-rate zone and the trainer steers the power to hold you there, whatever your form is that day.
And more: Time Trial, Free Ride, Sprint, Overtake Mission, Interval Quiz, the Track Builder, Ghost Duel, and a daily Discover mix that hands you one ready-made ride from every mode.
PHYSICS YOU CAN CHECK
The model is public. Open the physics page and you get a PASS/FAIL table comparing our numbers against independent calculators — 200 W on the flat, 300 W up an 8% grade, coasting down a 5% descent. Nothing is tuned to flatter you.
LEADERBOARDS A BEGINNER CAN WIN
Boards are scored by watts per kilogram in classes A to D, and by an FTP-normalised "vs par" axis that does not depend on how long the stage is. A newcomer with a good ride can top the board. FTP plausibility and repeat-ride checks run behind it, with a VERIFIED badge and a verified-only filter.
TRAINERS AND SENSORS
Bluetooth FTMS smart trainers with resistance control, heart-rate straps, cadence and power meters. Every mode is fully playable without any hardware at all.
YOUR DATA GOES WITH YOU
One-tap sync to Intervals.icu, a manual Strava connection, and a FIT or TCX file for every single ride.
