Yesterday I posted a Flashback feature pointing to the Gomicycle Honda Rebel 250 electric conversion project from MAKE Volume 14. West Virginia Tech University mechanical engineering student Justin Cole wrote in the comments:
I like the idea of a feasible and cheap electric motorcycle. I liked it so much that I built one as my senior mechanical engineering project last semester. My team and I built an electric motorcycle with the budget and simplicity in mind. A few basics were to keep costs down, get a decent drivable distance, and keep the design of the bike simple so that builders and makers at home could build this if they felt they had the skills needed. The total cost of the bike came out to $2100 and has a range of 25 miles. I set up a website through my school and have submitted it to Make before but I guess its not fit for Make. Our whole project report in available for download on the downloads page along with videos of the bike in action and a few of the drawings. The report has a full 18 page appendix with all the figures and graphs that we used. Our Excel spread sheet is also available. If anyone is interested go to http://sae.wvutech.edu/projects/electricbike/.
Awesome, Justin, thanks for sharing! The project site is comprehensive, offering design, components, research, build photos, videos, and an entire page of downloadable reports, specs, and diagrams. A perfect fit for MAKE, actually, and a great resources for folks working on motorcycle conversions.
