i am thinking of doing a 48v 1000w that im looking at on ebay, front wheel. I have a bike that ive been using as my towing bike, carting laundry and whatnot and i want to fit the battery pack on the rack. Right now im in the process of moving into a new apartment and trying to generate interest in my old bike so i can sell it for more money to start an ebike build. I didnt realized i had been getting lots of replies... the bike candidate i have now is a girls bike with a rack on the back 26 inch.
