I’m stoked to hear this project is working out long term! Please keep updates coming, if you spent $400 on this I’d be looking to go a little higher for better brakes . I have an e-bike I use for work so I already have a battery and charger, it’s the hub motor that’s the next stop. The lights is interesting too, trac has a battery 6v system but it’s super dim at a stoplight, I augment with bike lights. What is the tire size on your set up? 16 or 17?
