Use a KICKR Core without a subscription

The trainer is yours. The subscription is to an app, and the app is a choice.

Monsoon Cycles, Colorado Springs · Updated November 4, 2026

The KICKR Core works without a subscription to anything. It is a Bluetooth FTMS trainer; the subscription is to the app, and the app is a choice. Zwift's free tier ended in December 2025. MyWhoosh is free but is an install of several gigabytes. Gumwall Grand Prix is free in a browser tab and drives the Core's resistance with real circuit gradients.

OPEN THE GAME HOW TO PAIR

Set up in two minutes

Update once, then forget the app. Open the Wahoo app, let it update the Core's firmware and do a spindown. Then quit it. A trainer talks to one app at a time.
Open the game in Chrome or Edge and click PAIR SENSORS, then Smart trainer. The Core shows as KICKR CORE with a number. Pick it.
Pedal. POWER and CADENCE fill in. Pick a course and ride. The trainer difficulty slider in the BIKE tab scales the gradient.

KICKR Core questions

Can I use a Wahoo KICKR Core without a subscription?

Yes. The KICKR Core is a Bluetooth FTMS trainer. It needs no app to work and no subscription to any app. Gumwall Grand Prix pairs it free in Chrome or Edge and drives the resistance with the course.

Does Wahoo charge for anything?

No. The Wahoo app is free and is only needed for firmware updates and spindown calibration. Wahoo's own training app, SYSTM, has a paid tier, but you do not need it to ride the trainer.

Is the power accurate without Zwift?

The power comes from the trainer, not the app, so it is the same number in every app. The Core is rated within two percent.

What about the KICKR Core Zwift One?

The Zwift One with the Cog pairs the same way over FTMS. You ride one gear and the trainer resistance follows the road.
