On the flat I would normally ride gearing 10 to 13. Last few rides I have had to ride 21 or 22. This is on a Wattbike Atom. I have checked firmware and OK, wattbike atom also rides OK on wattbike app.
I’m on atom version 2. I also tried on version 1 wattbike, similar problems apart from Zwift gear not showing a change but the bike did.
Any ideas?
