wesnewell and markz, thanks for the wheel building tips.
The 500w bike weighs 72 pounds but that is with: the lock, tools, extra tube, 1/2 full water bottle, first aide kit, 15 x 8 Mj1 battery, bathing suit/goggles/small towel. I keep this bike outside on my balcony year round. It cost $35 and still has all the original parts except tires, brake pads and seat. I weigh in at about 140 or so.
Today, the 1000w bike weighs 81 pounds. That is with all the same items: tools, lock, extra tube, 15 x 12 p22 battery, suit, first aide stuff, water... When commuting, I usually have lunch and a clean shirt in the back bag. I carry it up and down the stairs. Here is a picture:
I start work on Monday and have made some changes to the 1000w bike. First, I had a bad wobble, at the end of the school year, even though the wheel was true. After cleaning the rim, I noticed several large cracks so I ordered the wheel stand. I also ordered and extra 1000w kit from ebay (the $155.00 ebay kit that wesnewell posted earlier) just incase I did not have time to build a new rim into the hub. The kit came without a cassette/sprocket but I had an extra one. It is similar to the yescomusa.com kit except the wires to the motor go in from the left/non cassette side.
Last week I pulled out the new hub motor, added a rear cassette, and put it in the 1000w bike. I hooked it up the 4 year old yescom controller and went for a test ride and it seems to have the same speed as the yescom 1000w motor. I also got a new front wheel from the local bike store and new brake pads from amazon. I have new tires, straight wheels and am ready to start the school year.
Just about everything is broken on my 2001 Hyundai. Last winter the hood flew off while driving on the freeway. The welds broke, so now it is held together with bungee cords and a strap. The lights go on an off while driving at night, and the check engine light is always on (so it will not pass smog). So, I decided to go without a car and donate it to charity when the registration expires in 5 days. My wife and daughter both have cars and I have a tandem bike If I need to pick-up one of my kids or go somewhere. Hopefully it does not rain much this year.
Here is a video of me picking up my son from school last year.
My oldest daughter has seizures (epilepsy) so I had to build her a special seat. Here is video of me goofing around this summer with my daughter:
I will report later on the wheel building and the 25R battery build.
