What is all that gunk in there? Just part of the belt that gets chewed up or does dirt/debris somehow work its way in there?
E-bikes are a thing
- Thread starter jdog
- Start date
kinda looks like the belt teeth that have sheared off
But what percent of them have destroyed sprag clutch bearings? Over on the EMTBforums that's mostly what you see. Going to pull mine apart this weekend to check to see what's up inside. My guess is it's the sprag bearings.
There are better quality belts available than what Specialized uses.
Here's a good video of what's going on inside Specialized's Brose motor and it's issues.
Off topic here a bit but I made a Smoothie yesterday and the rubber gasket seal popped off during the blending. Looked just like that.
Wasted a good Smoothie. :*(
Seems about right for my motors, but my customer's seem to fair much better than I do. 2 emtb's and I'll be installing my sixth motor today. Out of all the other e-bikes I've sold I haven't had to replace more than 2 motors total. The one's I have replaced have had some kind of issue right out of the box and they were replaced before they left the shop.
We really need to start working on the POS e-bikes out there. My phone doesn't stop with people who have some Amazon e-bike that won't go anymore.

at that point maybe just get a new bike every year or 2 and sell the old one.

Got 14,000 miles & 5 years on my Powerfly Bosch motor, no problems. 😀
just to avoid doing the service, or does it take you over a year to put 100 hours on a bike?

Now that Sram is using a Brose based system it’ll be super interesting to see what the next generation of bikes will look like. If a Manufacturer can build a bike from a single source that’s a huge benefit for them over using multiple suppliers. We could see Bosch-based bikes switch over because it’s cheaper and everyone loves a healthy bottom line. Especially when the Industry is taking a face first swan dive into the ground.
Problem is bosch is the most reliable motor out of the bunch which is why so many brands dumped ep8 in favor this past year. Im sure we are gonna see Sram appear on more brands but they all need to be able fixable. Brose is the only one besides bafang that people can actually have repaired, the others are throw aways, though me thinks the manufacturer is probably rebuilding those.

I’m hoping Sram opens up service parts availability for current product. They’re usually good for that stuff. That would open up options for dudes like Gary that blow up 3 motors a year. A $30 belt kit is so much easier to swallow that $1,000 for a new motor.

What shows up when you Google the motor your bike has? Brose belt kits pop up from a couple of sources at around $160.
I would probably do it... considering how little fear I have tearing into any of my cars that cost multiple times more than any e-bike.

Today I found out some interesting stuff about my Cdale.
First I got a battery cold alert on the app on my phone. So I took the battery out to charge inside for the first time…..gotta say, cool setup.
Second was a vine pulled my rear wheel sensor out of its holder, boy did the bike miss that sensor. But once I got out of the woods, it was an easy fix….happy about that!!!
