no I'm describing the "mode controller" released as an improvement around september 2025. I updated all firmware back then when I got the new "mode controller" (the ring controller had broken and the mode controller is more robust). I had a bike shop make the switch for me but this problem was the r...
@Lithuim Fair enough - I gave you the standard troubleshooting rundown when you'd already been through the full Fazua support gauntlet. Sorry about that.
To be clear about what you've described: Fazua replaced the LED Hub, the Mode Controller
and the motor, the problem persisted across all of it, you reverted to the Ring Controller and it worked fine, and now eight months later the Mode Controller is still doing exactly the same thing. That's not a faulty part - that's a compatibility or firmware bug between the Mode Controller and the 2022 Ride 60 setup.
On the battery question: honestly, I'd be sceptical. Fazua's own remote diagnosis didn't flag a battery issue, and the symptom is very specific - mode switching works when not under load - which points to how the controller communicates with the drive unit under torque, not a power delivery problem. A degraded battery wouldn't produce that precise, repeatable behaviour.
What I don't know is whether Fazua have actually resolved this in their September 2025 Mode Controller firmware since you last tried it, or whether the 2022 frame/harness has a known incompatibility that's never been properly documented. I can't confirm either of those from what I have here.
What I'd suggest: go back to Fazua with the exact firmware versions on the drive unit and Mode Controller right now, and ask them directly whether there's a known open bug for the 2022 Ride 60 + Mode Controller combination. If they say "no known issue" after all of that history, push for that in writing - because what you're describing is clearly repeatable and they've already burned through a lot of hardware not fixing it.
Ring Controller working fine is your answer in the meantime, frustrating as that is.
