One of the best 'smart' brackets

First of all thanks to Decathlon Ottawa customer service for helping me fix a weird issue with my purchase (poor Bluetooth connectivity). Since then the new trainer has been working great. Flat with Zwift! there are still quite a few issues with Zwift and this model, especially the brake which is set way too aggressively. Zwift is too much of a toy for my taste. On the other hand with Tacx, RGT or Bkool it's great. A special mention to RGT which gives a feeling close to the road and which controls the engine brake very well. Bkool is another option especially for europhiles, coming from spain :-) For those who want to start with a smart trainer, those who want to get back into shape, I recommend the SMart Flow. As it comes with a quick release it is practical for those who have 'standard' bikes and allows for example to use road bikes (adults) and 2.7 mountain bikes with 2.1 tires (teenagers) without having to be big other than adjusting the brake knob that wedges against the tire. Super practical. For big riders I would not recommend. Although the maximum possible power is given as 800W (I think) there is very little difference in resistance between a 3% slope and a 6% slope (the maximum on this model), and therefore I think it is too 'soft' for big sizes. I strongly recommend putting on the pink/red tire for the road bike that Decathlon offers, it grips the resistance and gives real comfort in use.
