I had a good bike siting in the backyard so to get my fist eBike going was not very expensive. I did have to change out my forks but that allowed me to repack the front end too. After the fist ride I decided to referb the entire bike. The total weight is 35 lb with the "sprinter" battery. The battery is what tipped the scale for me. It weighs 3 lb and can get me to town and back which includes some serious hill climbing. A road side radar speed limit sign in my neighborhood clocked me at 17 mph on a flat stretch which I think is accurate. The kit got me riding everyday.
