Hello all. New person here. I have been doing a lot of looking into getting or building an electric bike but the costs are overwhelming for my budget. I work full time and walk to work. It takes about 35-45 minutes to walk there and want an easier method to get there and home, as well as going to Tue store and what not in town. I have a family to take care of and rent and all the bills that come with it, so cost is a big thing when I make $10 an hour. I am not looking for anything over the top. Just something in the 10-20 mph range that can go 20-40 miles per charge. I can get my hands on a good bike and what not, but the other parts I am in need of assistance with. I see the kits online and the prices are not bad, but none come with a battery. I do understand a new battery is the expensive part, but what other alternatives are possible, for example a used motorcycle battery or golf cart battery/motor, or other alternatives? My price range is limited though, as you can tell from what I sad earlier. Something in the range of $150-$200 would be best if possible. Any help would be great. Thank you for your time.
