I hope to have this finished in the next few weeks, just waiting on parts I bought off of ebay. If you live in the Colorado Springs area and are interested in building an EV motorcycle, or currently have one, feel free to contact me at We can share information. Thanks.

I'm gonna sell the project. I need to simplify and have too many projects going on. I tested it and it ran. Enjoy finishing it up. Make offer.
