I guess this post is about a week late. I have built a couple gas bikes and I just finished a bike with an electic front hub motor. I joined this group from a link in Spookytooth Cycles' web site. I built a Nirve Switchblade chopper into a gas bike, which required a lot of mods to get it to work. That was probably my biggest motorbike accomplishment. The next thing I am working on is a $25 mod to change a brushless electric motor into a 2-speed motor by installing an extra set of hall sensors with advanced timing, and switching between the two. There is a lot of good info in this forum and I will try to post new stuff when I think of it. Some of the stuff I have figured out might actually be useful to somebody.
