I stumbled upon your forum after doing a google search for DIY mopeds. I must say, this is cool! I didn't know what these bikes were called, but I knew they existed because I see them all the time. There's a big motorized and manual cycling scene up in the Twin Cities. Anyway, I was wondering about a certain bike. Would you be able to turn this bike right here into a 50cc moped that travels at around 30 MPH with working headlights, tail lights and signal turners? That's all what it would take to make it street legal. http://www.americanlisted.com/kansa...4-3229_www_edrop_tv_myedrop_com_12842615.html I picked out this bike because it works out for me very well. I kind of have a small body frame (5'10" 160) and I barely bottom out the suspension on that bike. I prefer smaller bikes because I prefer the agility of a BMX over the visibility a 26" MTB would offer me. Furthermore, if I do bottom out my suspension, I have a spare suspension coil from one of my other bikes in my house. Take care!
