My wife took my new BBSHD build for a ride the other day and came back with a big smile on her face. Now I'm trying to figure out how to convert her bike to an eBike. Her bike has a Nuvinci N360 transmission on it, so that leaves out rear hub motors. I'm also hesitant to go with a mid-drive for fear of destroying the transmission. Hence my only option is a front hub motor. I know nothing about them however. What are your recommendations? I'd like it to have a reasonable amount of power 750+ watts, but don't want to add 20 pounds to the front of the bike. Are there any good options?
