My bike is so unique, I couldn't not show the pride for our country and what is possible with electricity produced here in the United States.
I emailed the manufacturer, Crystalyte, about the dimensions of the motor to make sure it will fit in my rear drop outs. The motor must be the exact width of the dropouts because the aluminum swing arm can loose a lot of its strength if permanently bent into a new position. This is not good when the motor produces around 80 Nm of torque.

Weighing the motor on a seafood scale to get a good estimate on how heavy the bike will be after it is finished.
After 700 miles of off roading and hill climbing, I decided it was time to check the status of the windings and make sure they were not cooking. If I am riding in a way that is too much for the motor, it will eventually short out or the excess heat produced will demagnetize the magnets. Both are bad. However, after 700 miles of some rough riding, the windings are good and there are no signs of overheating.
This charger has the ability to charge all of the cells in parallel. This charging method is slower then my other charger because all of the packs are paralleled, however it monitors each of the cells during their charging. If the charger notices something wrong, it will shut down charging and help prevent further damage.
This charger allows me to charge my bike at the full pack voltage of 82 volts. This is good for faster charging the my other charger, however it does not tell me how well each of the 20 cells are doing. The individual cell levels are checked every 10 cycles or so with my previous charger.
This is my battery harness. It is comprised of connectors that are permanently connected to the batteries. These connectors don't connect the battery's to each other in anyway. The connectors on the top connect the batteries in series or parallel, for either discharging or charging respectively.

Electric Bike Build

After a year of paying for gas, I decided I would help stop rising gas prices by building my own, green, mode of transportation. After a year of planning and research, I built the perfect anti-gas mode of transportation. The electric bike houses a total of 10 batteries; 2 in parallel and 5 in series. This provides a 82 volt 10 ah battery pack that is good for cursing 7 miles at 35 miles per hour. With a gentler throttle, the bike can see 20 mile cruises.
