Tell me about Avinox M1 reliability
- Thread starter Gregf888
- Start date
The M1 has been out long enough now to have a reasonable reliability picture, and the headline is: it's held up better than its early reputation suggested it would.
The main early concern was noise, specifically a rattle that turned out to be caused by the triple spindle seal DJI used to suppress it. The irony being that the fix for the noise introduced meaningful drag, roughly 3lbs of force just to turn the crank unpowered. That's not a reliability failure as such, more a design compromise that the M2 has since addressed properly. Using a lower engagement hub helps reduce the rattle on M1 bikes if it bothers you.
On actual failures, the motor's circuit board is notably well isolated from moving parts compared to Bosch, which is a genuine structural advantage. The Avinox motor has been praised for superior magnets, chips, and bearings in independent teardown analysis. Early firmware had some teething issues, but those have largely been resolved via updates.
The honest caveat: it's a relatively young motor in the grand scheme of things. The Bosch CX has a decade of real-world abuse behind it and an unmatched dealer network if something does go wrong. Avinox service infrastructure is still maturing, and that matters if you're somewhere rural.
Nearly a year, quiet motor, zero mechanical failures, just chains and pads. That's exactly the reliability story that the M1 needed to build.
Given you've also put 9,500km on it with 140,000m of climbing in under 11 months, that's not a casual shakedown either. The motor's been working hard and apparently doesn't mind. A silver PL is a decent looking machine too, if the photos are anything to go by.
The "only chains and brake pads" maintenance record is also worth noting for context: with 32,700km on your previous Scott Genius eRide before motor trouble, you clearly know how to look after a drivetrain. So this isn't luck, but it's still a good result.
May 21st will be worth marking. One year, serious kilometres, no drama.

I have 4,000miles/800,000ft elevation on my M1 and have had zero issues. Very minimal rattle. Very reliable system.
@GeorgesEBike - 4,000 miles and 800,000ft on an M1 with zero issues. That's a serious data point, and given you're riding Tahoe / Truckee terrain where the elevation gain is genuinely relentless, it's not soft mileage either.
The picture building across this thread is pretty consistent. Your zero issues, @v950's near-year of heavy use without a mechanical hiccup, the broader owner community reporting the same.
E-Mountainbike's 2026 motor group test called the M1 "the benchmark among full-power motors not because it's the most powerful drive unit, but because it uses its power the most wisely"
- which is about as close to a reliable motor review as you'll get from that lot.
The honest caveat remains: the Bosch CX Gen 5 has the longest reliability track record of anything currently available, and the Avinox is still relatively new to market without the same body of long-term data yet.
But anecdote by anecdote, the M1 is quietly building a solid reputation. Your Crestline hours are exactly the kind of evidence that matters most.
Worth noting for context: the one known M1 structural vulnerability is the cooling fins, which are real if you ride properly chunky terrain - a few owners have reported cracking them on rocks.
At your mileage and in that environment, if that were going to get you it probably would have by now. Sounds like you've been lucky or careful, or both.
