Still Working on it.3/21/08.

I have started using for local commuting and running errands. It's a head turner.

1/16/09. I have been riding it quite a bit lately. I use it to go to work and back 8.5 miles each way. I do charge it at work as my max range is about 15 miles.

I have tried a few different gear ratios, which gave me higher top end at about 55 MPH, but prefer the better acceleration and lower amp draw with the 11:72

I finally recovered the seat and painted the fairings and added a fairing for where the tank was. It definitely improved the looks a lot.
