I have decided to build an e-bike and came across your youtube videos (nice job!). I am very confident I can do this so I found a donor bike to start with. I got a Giant Talon 4 29er ($300!), 7 speed rear drive 14-34 tooth, Shimano derailleurs, shifters, and Tektro hydraulic disc brakes. I think I want to install one of your kits mostly because you have already done the engineering and your prices are good. Probably the Monster Range Commuter w/52v 25 Ah. Not Sure which brake cutoff though, Shimano EF500 Brake levers. Might need to buy a few tools but other than that is there anything I should plan for or recommended? I live in Ohio and it’s fairly hilly, no mountains. Shopping is 6-7 miles away on chip & seal paved roads. I would like to have a bigger gear in the back but I don’t know if there is another option without changing derailleur. Would like to figure all of this out before I buy anything. Would love your suggestions. Thanks!
