My first time posting here and have been using the search function extensively to answer most of my research questions (thanks to all of you just for that!) but I'm still coming up short and/or looking for confirmation on my approach to building my first e-bike.
My plan is to use a 2022 trek Farley 7 fat bike as my platform to build a mid-drive BBSHD set up. I am 6 ft 2 in 215 lb so I'm using an XL size frame. My local terrain is steep, rocky, desert sand on one side and mountain dirt Sierra forests on the other. I'd like to be able to ride steep technical rocky/sandy climbs and singletrack in the summer and of course snow packed trails in the winter (I'm in Reno,NV so we get plenty of both)
I've only seen one other Trek Farley e-bike build (Fat Bike Rider) but I'm sure there are more out there. From what I understand the bottom bracket is wider than 120 mm so some modifications will be required to fit the locking ring. Also since the 2022 comes with a 1x12 drivetrain my concern is the chain line for the bigger cogs. I've seen several folks recommend swapping to a 1x8 setup (not sure if this is enough gearing for my size and >20% grade climbs?). Other gearing recommendations? I'm not sure but I'm hoping a 36T lekkie will fit so maybe we can use this as a basis for front gearing??
In any case, I should have the bike on hand in a couple weeks and then plan to start ordering parts. Since the frame is an XL I'm hoping to fit at least a 52V 20Ah battery in the frame.
I'm open to hearing any thoughts or things to consider for this build from you more experienced folks. I plan to start a build thread as well once I get going. Thanks!
