I didn't realise the cassette wore down quicker on E-bikes. Luckily it's still under warranty. It's annoying that going at a good pace, changing to top gear and then slipping chain rears it's head. I'll see what bike shop says on replacement (via specialized) or me buying one and keeping one as...
After 9months I've had motor replaced. Now I can't use top gear as chain slips. (surely it should be years not months) All other gears are fine to use. Have I a duff bike? I'm tempted to stray from Specialized for the cassette/chain. Any advice?
I totally agree. I'd imagined they removed all cables/connectors correctly. Put new motor in and replaced cables correctly. Not sure why Specialized said its a common thing. The speed sensor is only a magnet attach via a wire and then connected to the motor. Has to be the motor, maybe...
Specialized said it was the clutch in the motor. It just crunched now again sounding like a slipping chain. So got new one. Fitted it and just cuts out after 10 secs. Now they're sending new speed sensor cable. Luckily it's a common fault so didn't quibble about me paying. Just hope it works.
Just a bit of advice. Bike being looked at tomorrow. But this gives me a heads up. Bike is 9mnths old. Been smooth until last week. Gears and teeth all fine. Its just started almost like chain slipping and crunching. I think it's definitely inside motor as chain/gears are fine. Any idea?
