Rocksolid guarantee

Shop with confidence. If it’s not working out, you can return it (consumables, electronics, undergarments and swimwear excluded).
Really. If it's not up to snuff after you use it (a couple times) you can still bring it back. It lasts longer than 30 days, but not forever. We'll be fair about it.


Just like you, the Tacx Flux Trainer is getting stronger over time. It's now upgraded with a heavier flywheel to give it a more realistic road feel. The resistance got a tweak to make sure you never reach its max level. At maximum 2000 Watts and 16% simulated incline, it's a given that you'll tap out long before the trainer does. Design-wise, it also has lowered front legs so it clears long-cage derailleurs.
