Wahoo’s KICKR is the most popular smart trainer in the world, and for good reason – it was one of the first, it’s built like a tank, and it’s backed by Wahoo’s solid support and distribution network.
Now in its 6th generation, things can get a little confusing if you’re looking to buy a used KICKR or pick up some new/old stock at a bargain price.

Great and useful info, Eric. Looks like it’s come about since your last update of this article, but for the next update you might want to consider adding “Race Mode” capability to the “hardware differences” table for the gen 5 & 6 models. Cheers!
It’s already listed in the Compatibility/Feel Differences table!
Please, the Kickr Core WFBKTR4, exactly what model is it? V5 or V4 What are its characteristics?
That’s a lower-spec trainer than the standard Wahoo KICKR. See details at https://zwiftinsider.com/smart-trainer/wahoo-kickr-core/
Do you have any more info on the TA adapter for the V1 kickr? I thought it wasn’t TA or disc brake compatible period!
Is the wahoo kickr v2 (wf113)( straight handlebar top) possible to make it usable for insert axle, a bike with disc brakes?
Yes, there was (is?) an adapter kit available for thru axles. Not sure that if it’s still available, but you could reach out to Wahoo support and ask.
What cassette was included on the various models? Someone is trying to sell an Ultegra 11-speed 11/23, saying that it’s a take-off from a Kickr, and I want to call BS on them because I’m pretty sure that all the Kickrs (except maybe the Core, with its multiple cassette options at time of purchase) came with 105 cassettes and 11/28 gearing.
My V1 KICKR came with a 11 speed SRAM cassette.
Do you know belt part number? For kickr v6 … I know it is the same as v4 … I got a “weck … Weck” noise. Looking for good price budget.. I don’t know if it will fix the noise problem.
Great reference for someone like me looking for a good used wahoo. Now I know it must be. V4 or newer!!
So much for the “it’s built like a tank, and it’s backed by Wahoo’s solid support and distribution network” unless you are in South Africa and get told that “We unfortunately no longer have new units, since Wahoo Fitness HQ has discontinued support for this trainer. No new units can be made available”. And you need a new drive belt, so you sit with ur finger in ur ear so a Kicker V1-V2 can’t be repaired, go figure
I am selling a V1 for parts as the power is fluctuating a bit and Zwift can’t support it with parts (too old), the belt is fine though.
