Trek Marlin do I need adapter
I am planning to put a Bafang system (Probably 1000w) on a new Trek Marlin 5 for my girlfriend. I am wondering if the Bafang system fits the bottom bracket "as is" or if I will need an adapter. Also, from looking at photos, I assume that the battery will not fit in the Marlin 5 woman's frame with the bend in the tube, especially since it will be a size small frame. Can anyone confirm that is true? Thanks

hello looking on treks site from what i can tell it looks like you will be able to convert with few issues. just make sure that battery fits in the triangle space, surely some shark batteries out there should fit.

Bottom Bracket - VP BC73, 73mm, threaded cartridge
so u get the 68mm motor size and that fits easily in your BB, you will want to add a 5 mm shim to make it snug, tho idk where these motor shims are available
