Thanks to everyone posting great photos and information on the forums. Without your ideas and information, my first project would not have been possible. My "nashmoto n1" is in R&D phase (started in May of 2009), but still a great ride. Powered by a 49cc Honda motor with Grubee transmission. Custom crossover shaft and NuVinci shifting rear hub. Custom designed and machined aluminum tank mounts and engine mounts. Now working with a new Honda engine and the 4G belt drive transmission from Grubee. Customized again of course. More photos, info and soon a blog of the development on nashmoto dot com.
