This is a kit to convert a 26” wheel bike to a 750W Bafang ebike. It's the same as this one: https://a.co/d/4SB1jlt. It includes a dual battery setup: one 17.5 Ah battery on a rear rack, one 20Ah in a triangle bag (https://a.co/d/4Iv93QN) in the frame and battery balancer (https://a.co/d/585jyud) so you can turn on both batteries without worrying about one back-charging the other. Also has a ton of accessories - two headlamps, two smaller panniers that fit onto the battery rear rack, two different controllers (large C961 that came with the kit, plus a smaller, sleeker DZ40), throttle, brake levers, a small hard case to enclose the controller box, and some rubberized C-clamps to attach the rack to the seat stays.
We built this setup as a backup to a different ebike (also Bafang but mid-drive), but we ended up not using it a ton. You can get a range of around 80 miles if you're in a medium assist level. Bike itself isn't included, but we can also sell you that if you want to re-convert it to an ebike.
