I currently have a 1500watt bbshd on a hybrid bike and I want to sell the entire package and make a new ebike. This time around I'm thinking about using a 3000 watt hub motor that will take me to the mid 40 mph range. I know I'll need a 72v battery pack and will see if a custom pack could be made to fit the bike I want. What kind of controller do you recommend that will allow me to use a display that I can use at night?
