yep some tips: i cant find the BB spec for your bike, likely its the common 68-73mm threaded, if 73mm, you want a lekkie one nut with some red lock tite to secure the motor, maybe offset pedals as well (your left pedal ideally should stick out about 1-2 cm more than the right to even the difference the motor housing protrudes). get at least four 2.5mm motor spacers, and one lekkie spacer, in case you need to space the chainring off the chainstay. what terrain are you riding mostly? dialing in your drive train for what you ride is smart. your cassette looks to have a 42t rear, just so happens that you usually CANT use front chainrings less than 40T/42T with bafang motors on MTBs due to the chainring offset, but you can on fat bikes with 100/120mm BBs. 42T lekkie chainring tends to be the sweet spot for all terrain climbing, with decent top speed as well, you have a nice 1:1 ratio for climbing that way. 52T the other extreme would be for top speed pedaling on flat terrain. do the conversion carefully, make sure your main cables have a gap either safely tucked between the motor and the mount or route them so they cant get pinched or damaged if the motor shifts. sandpaper and epoxy the magnetic sensors onto your brake levers once you set the magnets just right, do one at a time and test till its flashing the motor brake symbol when you pull your brake lever. 500c is the best display in my view. the BBSHD is a beast of a motor, bit heavier, only if you need the extra power. BBSO2 is good for being slightly lighter, less powerful at 750w but legal most places in the US
