2022 Pivot Shuttle SL mode controller only changes power modes when not pedaling?

Your 2022 Shuttle SL runs the Fazua Ride 60 motor, and what you're describing is almost certainly the Ring Control (the LED ring/remote on the top tube), not a fault.

Here's the thing: on the Fazua system the mode change is designed to register cleanly, and under load the controller can be deliberately fussy about when it switches. A few likely culprits:

1. It's the LED Hub / Ring Control behaviour, not a broken part.
The Fazua remote cycles through modes (Breeze/River/Rocket on the older naming, or the colour-coded Eco/Trail/Rocket levels). If it only responds when you're freewheeling, the most common cause is that the button press isn't being detected as a clean single press while you're putting torque through the cranks — vibration and grip change how firmly you hit it.

2. Check the firmware via the Fazua app.
This is where I'd start. Connect the bike in the Fazua Toolbox / app and confirm you're on the latest firmware. Early Ride 60 firmware had some genuinely odd mode-switch quirks that updates ironed out. If yours is a 2022 bike that hasn't been updated in a while, this is the single most likely fix.

3. Is it actually changing, or just not showing the change?
Worth confirming whether the assistance doesn't change under power, or just the display doesn't update until you stop pedalling. Those are two different problems — the first points to firmware/controller, the second is often just display refresh.

I'll be honest: I can't confirm from here exactly which remote variant your specific 2022 build shipped with (Pivot offered the SL across a couple of control setups), so before you spend money — tell me exactly what's printed on the controller, or grab a photo of it. "New mode controller" suggests you've recently fitted or swapped one, and if it's an aftermarket or replacement unit, a pairing/firmware mismatch with the drive unit would explain this behaviour precisely.

If you've genuinely just installed a new controller, that's the prime suspect — re-pair it through the app and update firmware on both ends before assuming anything's faulty.

What's the controller you've got on there, and did this start right after fitting it? That'll narrow it down fast.
 
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 result. I spoke with Fazua, they remote logged into my bike a number of times and couldn't find anything wrong. They sent me a new LED HUB, a New "Mode Controller" AND and a new motor, all were replaced, firmware updated and the problem persisted. so I got a replacement "Ring controller" and went back to the original setup and that worked fine. Now 8 months later I assumed they had finally fixed this "Bug" with the Mode controller, I updated all firmware, installed the "mode controller" again and called fazua they remote logged in and updated the bike to be compatible, tested it and said I was good to go. I got off the phone and as soon as I turned the bike on and started pedaling it would not change motor speeds, it's not an issue of the led not updating, you do not feel any change in power assist. it's only if you stop the bike or roll for 5 seconds and move the mode controller that it will actually change the motor speed mode it is a know problem that has been repeatable. I wonder if a battery replacement would fix this?

@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.
