Bosch cranks and chainring question

[AssegaiRear]

Hi, everyone. I'm new here, thanks very much for having me, and looking forward to any insights anyone can provide with this problem I'm confronting. I own this bike:

Rail 9.9 XTR - Trek Bikes

www.trekbikes.com

Or rather that frame, with a Bosch Gen 4 motor. The components were/are much lower spec. I have about 5000 miles on it, and I'm really tired of snapping chains and so on. Right now, it has a full SRAM X01 mechanical drivetrain on it, and I'd really rather keep it that way to maintain compatibility of my wheels across my fleet of bikes.



Just yesterday, I snapped a new XX1 chain, loosened, and damaged my brand new Hope e-bike chainring. I had concerns about using an alloy chainring due to the nature of e-bikes, and this kind of confirmed the problem. So here is what I want to do, and I'd love all of your thoughts on whether its feasible or not:

• If I upgrade to an absolute black super steel chainring, can I keep using my Hope e-bike cranks? Everything I've seen indicates I should be able to, and indeed that any Bosch compatible crank arms should work on any Bosch compatible chainring.
• If I upgrade to a Shimano HG+ chainring, can I run an XTR chain on my otherwise SRAM 'train? XTR chains are, according to Zero Friction Cycling, the only decent e-bike rated mechanical chains. I have unfortunately also snapped at least two KMC E12 chains.
• If I upgrade to an absolute black ring, could I squeeze a 38t on there? My understanding is that larger chainrings place less mechanical/motor stress on the rest of the drivetrain. The Trek site says max chainring is 34, but I'm pretty sure I could slap a 36 on there without trouble. A 38 is much iffier.

Any insights would be very much appreciated. Thanks again.
