@Stredda what is your local ride like?
I have heard some stories about people needing multiple motor replacements where they ride some steep stuff.
I ordered a Jam2 with a Bosch motor based on most people’s advice. Sounds like yours has been bullet proof.
I do ride it to work a lot, so there's a lot of those Km that are just road and shared Pathway, but when I do go off road, I like to do a fair bit of exploring up old fire trails and some of them are bloody steep, like impossible on a normal bike and a real challenge on the Ebike. Then there's just normal mountain bike riding on single track.
All motor brands have issues, just some more than others. The Mahle motor in the Levo SL has proven pretty reliable from what I have seen of a few forums. The full powered Levo on the other hand had heaps of belt breakage issues for a long time but I think they may have it sorted now. I haven't seen one brand or model that someone didn't have a problem, it's just the percentage of issues that change.
I plan to hang on to this bike for a long time, so I'm glad it can be rebuilt either by yourself or shoot it up to the
Ebike Motor Centre. They also support Bosch, Brose (Specialized), Yamaha (Giant), TQ, and Mahel motors, but only sell bearing kits for Shimano motors as Shimano won't share the fault codes and opening up the motor can cause a fault code that cannot be removed. All fine under warranty, but when the warranty runs out, you are on your own.
I did replace the sprag bearing and put new crank bearings and seals in my motor a while back. I think next time I will shoot it up to the Motor Centre for a full refurb.
Bosch do seem to be pretty good when it comes to after sales service.
