I have had a couple of different ebikes (Scott eSilence and now a Hybrid Speedmaster) and on both I found that the cassette wore very quickly – I started experiencing issues with gear changes at around 2000kms and had to replace both chain and cassette. Googling indicates this can be a common issue, and I want to find out if it is the way I use the bike that is an issue, or just something to be expected based on the torque applied by the motor.
Hi Michelle, how are you? From what I’ve heard that seems to be about normal. Do you have a chain wear measuring thingy? That is useful to determine when to replace the chain, and you should be able to get 2-3 chains per cassette. OTOH my rear hub Specialized goes through about 1 cassette in 15,000kms.
