Several years ago for fathers day I bought myself a kit to convert a bike to be electric powered. The problem is that I cheaped out and didn't get a battery to go with it. I figured since I was the battery guy at Kyocera I could make my own battery. It was actually a good idea but to make a battery that was the right capacity using cell phone batteries would take a hundred or so cells which would include a lot of welding (which we weren't really set up to do) and then I would have to build a custom protection circuit for it so it wouldn't blow up. This meant that my electric motor and motor controller just sat there for a very long time.
Finally I got tired of looking at it in the corner of my bedroom and last spring I sat down and ordered some gel cells on-line. When the gel cells came in one had a big crack in it but it took another three months before I actually got a box suitable to hold the batteries in. When I finally tried it all out it worked but the motor kept cutting out. I finally figured out that the damaged battery had a high self discharge rate and was causing a low voltage. I called up the people I bought the battery from and they wouldn't take it back so I negotiated a discount on a replacement battery.
Unfortunately they didn't have any batteries in stock. I think they were lying to me and just didn't want to give me a new battery. I asked them to let me know when the batteries came in but of course I've heard nothing from them. I finally got tired of waiting for them so a couple of weeks ago I just bought myself a battery here in town so now I was ready to go. Well as I was pumping up my tire I noticed that I had two broken spokes. Since the motor and the batteries are both very heavy I decided that I shouldn't ride on broken spokes so I stopped at the local bike shop and bought me some spokes and a new tire.
When I sat down to replace my spokes I realized that I had to take my sprocket off to replace the spokes but I didn't have the right tool. I finally broke down and took the whole wheel in to the bike shop and had them do it for me. A few hours later I got a call from the bike shop telling me that he broke two more spokes trying to fix up my wheel and that I just needed a complete new wheel.
Well it's cost a lot more than I was planning but yesterday I rode my newly converted electric bike to work. I run's like a charm and I rode it again today. The amazing thing is that I can ride this bike in about the same time it takes me to drive in traffic. I'm actually faster than traffic if it is bad. Without the motor I can ride in an hour but with the motor I can be there in half an hour. I love it. The best part is, if I drive it costs me about $5.00 in gas ($7.50 if you include taxes, insurance and depreciation on the car). If I ride my bike it takes about $0.03 of electricity. How do you like that?
