Thanks! It would be great to know if we could at least order it!
I don't think it exists. You can't bolt it to the frame with only the two mounting points. It'd have to be something like the
wolftooth bash ring. But I think that would mean you'd lose the chain guide, so pick your poison. If you have the two-piece spider and ring that comes on the nicer builds, I think you can just order one of the bash rings and it will work.
If not, FSA (which is out of left field) makes the spider. I couldn't find as a consumer, but my LBS was able to backorder one. I traded all the parts back to my LBS for credit and the cranks and ring are the only thing left. Planning to keep the cranks, but go to a SS wolftooth ring as soon as I can get my hands on the spider.
Not sure how other ebikes handle this as I'd never consider a full-powered ebike and wasn't willing to listen to the EP8 rattle, so haven't looked hard at other ebikes. I would never buy a real bike without ISG tabs, but I was really buying the TQ motor with the frame it happened to be attached to (not that I don't love the bike; there just weren't any other competitors to choose from).
As an aside, the BB is low as f*ck. The BB height numbers in the geo chart are either errors or weird CAD numbers. Compare them to those for the new EX and the EX drop. Makes absolutely no sense.
What matters is the BB drop, and 41mm in low is way lower than most comparable bikes. I'd caution against throwing it in low and never considering high, especially if you're doing "trail rides" as opposed to pedaling up fire roads and plummeting down with little pedaling. Took me a minute to figure out why I was struggling with pedal strikes because I was being lazy and looking at the quoted BB height and not thinking.
Hope this helps.
