A free trainer game for kids

No account, no subscription, no chat unless you sign in. Short circuits, bots to race, any bike on any trainer.

Monsoon Cycles, Colorado Springs · Updated November 4, 2026

Zwift ended its child accounts, and a ten-year-old does not need a $19.99 subscription to ride a trainer in the garage. Gumwall Grand Prix is free, runs in a browser tab, needs no account, and works with a kid's bike on a dumb trainer with a speed sensor as well as with a smart trainer. There are bots to race and real circuits to ride. The shooter mode is behind a button and off by default.

Why it suits kids

• No account, no sign-up, no email. Open the tab and ride.
• No chat unless signed in. A kid riding without an account cannot be messaged.
• Short courses. Monaco is 3.3 km, Laguna Seca 3.6 km, the velodrome 333 m. A lap is ten minutes, not an hour.
• Bots to race. The bots ride at a range of speeds, so there is always someone to catch.
• Any bike, any trainer. A 24-inch wheel kid's bike on a basic trainer with a Bluetooth speed sensor works; pick the wheel size from the 23-size list.
• Free, forever, with no premium tier to nag about.

About the shooter

Freedom Mode turns the lap into a cartoon shooter against delivery drones and licence plate cameras, with an arena-shooter announcer. It is a pink button at the bottom left of the ride, off by default, and it never shows on a phone or tablet. Shooting a rider or a car costs points, not the other way around. If you want to be sure it stays off, ride on a touch screen, or just tell your kid the pink button is yours. What Freedom Mode is.

A setup that works

1. Family laptop or Chromebook with Chrome, plugged in, on a stool in front of the trainer.
2. Kid's bike on a dumb trainer, speed sensor on the rear wheel, or a smart trainer if you have one.
3. Open the game, PAIR SENSORS, pick the sensor, choose the wheel size and the trainer curve.
4. Pick Gumwall Speedway or Monaco, turn the bots on, and go.

Questions parents ask

Does my child need an account?

No. The game runs without one. Sign-in is an email link, optional, and only unlocks leaderboards, multiplayer names and chat.

Is there chat?

Only for signed-in riders. Without an account there is no chat and no way for anyone to message your child.

What about the shooter mode?

Freedom Mode is behind a pink button, off by default, and hidden on touch screens. It is a cartoon shooter against drones and cameras with an announcer. If you would rather it never appeared, the game can be ridden in demo mode on a phone or tablet, where the switch does not show.

Does it collect data?

No ads, no third-party trackers. The site keeps first-party page counts. Without an account nothing identifies the rider.

Will it work on the family Chromebook?

Yes, in Chrome. The Chromebook guide has the three steps.

Why did Zwift stop child accounts?

Zwift closed its free child accounts and now requires every rider to be an adult subscriber or on a family plan. A free game with no account is the simpler answer for a kid who wants to ride a trainer in winter.
