How it works

  1. 01

    Tell us about you

    A nickname plus height and weight — used only to model your speed from your power.

  2. 02

    Connect over Bluetooth

    Pair your smart trainer or power meter — heart-rate and cadence too, if you have them.

  3. 03

    Pick a race

    Choose a mode and pace tier, or jump into a live multiplayer room.

  4. 04

    Steer with ← →

    Pedal to set your speed; use the left and right arrow keys to move up and down the track.

Before you start

The web ride pairs sensors over Web Bluetooth, which runs in Chrome, Edge, Opera, or Brave on a desktop or laptop with Bluetooth switched on. Safari, Firefox, and mobile browsers can’t pair smart-trainer sensors — open this page on a computer to ride.
