Hello, just joined Zwift, with noted indoor bike. The app and bike easily connected and in my first workout all functions such as cadence, output, work correctly. Merach manual says auto resistance change should work with Zwift (It does with Kinomap), but no joy. I have looked and note the bike i…

Hello @Mark_Goodrich and welcome to the forums. I’m not familiar with this bike or know if it should be changing resistance automatically, but you should be connecting (pairing) it as both power and resistance on the pairing screen when first starting up Zwift.

Yes, Mike, thanks for replying. The app actually did connect with both. I’ll try a hilly route tomorrow and see if I can get it to work.

Some previous discussion of the Merach S09 [image] N00B to Virtual Cycling ?s General Discussion I’m new to virtual cycling. Forgive my ignorance about how things work. I have a Merach MRK-S09-76 with power, cadence and controllable features. When doing a free ride, th…

Thanks, Paul, discouraging thread, that. If I can’t use the auto resistance change feature with Zwift, I’ll likely have Amazon come pick the bike up. So that raises the question, is there a bike in this price range that DOES do all the standard stuff like cadence, power, and auto resistance? The …

There is also a qdomyos-zwift Facebook group where you might find other Merach bike owners using QZ. The Compan…

Thanks for the suggestion, Mike, ill look into it, but I would prefer something like the Merach that’s fully functional with zwift.
