    Turbo Levo Brose 1.3 Grinding Noise

    What do you guys think could be the cause of this grinding noise on my Turbo Levo 2018 bike ? It's coming from inside the motor, only when using pedal assist. No noise when backpedaling, and when the assist is turned off there is zero noise. It starts about 20 minutes into the ride, and from...

    "toc toc" sound coming from new PW-X3

    Hi all, I am riding a brand new Raymon Hardray E 7.0 with the Yamaha PW-X3, just bought it last week. I want to understand if a noise I hear is normal or not. The concern is due to the fact that for the first 20-30km it did not make this noise (maybe I didn't notice it?). The noise is coming...

    Other SOLVED: Specialized Levo (2018) Brose 1.2 Motor - Clunk Noise

    I own a 2018 Specialized Levo Hardtail and has been a joy with zero problems until now. Unfortunately it has developed a ‘clunk’ when pedaling under load in the highest gear (small cog). Please take a look at the movie, as I need advice… https://youtube.com/shorts/mk8VYzW8zZw Thanks for...

    Comparing noise from 8 emtb motors

    We’ve taken a closer look, or rather listen, at 8 of the motors we’ve ridden lately. This is a comparison of full power emtb motors, yet one of the contenders is the small and mild TQ HPR50 motor. This is the most silent motor we’ve ever ridden, so we included it as a benchmark. Sure, it’s a tad...

    Why do my disc brakes keep becoming contaminated?

    Since I've had the bike, I've repeatedly had problems with screaming brakes. I've come to the conclusion that it's simply contamination. On the rear brake, I put this down to careless washing on my part transferring crap from the drive train. Both front and back brakes have similar problems...

    Shimano e8000 knocking noise

    Afternoon all, On a ride this morning and about 10 miles into the 30 mile ride after some shredding on local trails I noticed this knocking noise. Lifted the rear wheel (motor still on) and just span it using my hand not turning the pedal and on every revolution it made a knock. Did the same...

    2017 Levo FSR jangling noise from back of bike at speed

    I have a 2017 Levo FSR purchased 4 months ago, which has had an irritating noise since new. Above about 15mph, a jangling noise is evident from the rear of the bike. At first I thought it was from the motor, but am now reasonably certain it is from something striking the brake rotor. The black...
