Ebikes wear out components faster than regular bikes. Especially chains and cassettes.
Don’t get in your head that a more expensive cassette or chain will be more durable. In my experience at my shop this is often not the case.
The Formula hub they use on the base Roval wheels are used on Bulls, Haibikes and several others. Sram uses this hub as well.
In my experience I have seen more failures on Kenevos ridden at bikeparks than Levo base and comp models. But I have seen the same failures on other brands I sell as well, so it’s hardly isolated to Specialized. The only reason I see more Specialized failures is because we sell Levos at a 20 to 1 ratio against all of the other bikes we sell combined.
I don’t think the Formula hub was designed as a purpose built Ebike hub and while there are failures more of them have not failed.
We sell a lot of DT Swiss Hybrid hubs as an upgrade. It’s certainly not the lightest hub, but it has proven bulletproof in my experience.
