Fantastic indoor trainer for serious cyclists
I've been using the Tacx Flux S for several months, and it has transformed my winter training. The power readings are very accurate, and it pairs seamlessly with Zwift. The ride feels natural and smooth, and the noise level is impressively low.

Great value but limited incline simulation
The trainer is solid and reliable, with good app compatibility. However, I wish it could simulate steeper gradients beyond 10%. Still, it's a great option for indoor training without breaking the bank.

Sturdy but a bit heavy
The Flux S feels very stable during intense rides, which is reassuring. The only downside is its weight, making it less portable. Overall, a dependable smart trainer that meets my training needs.
