Well heres my 25 cents (2cents dont do nothing) I havent been here very long but as fast as people are joining I feel like a veteran, I just built what looked like fun to build,after looking at what I had to build with. I could have used a curved frame for a base, I actually have two, I originally wanted fat tires but being a novice at bike building I didn't even think about the width of the triangle and other things didn't fall into place as planned. But it was a learning experience I think the rules worked well for the build... if I could just get my wife involved in a build to see how much fun she is missing but I shouldn't complain,she works her tail off just keeping the family machine in fine tune she just gets jealous of the time I spend in the garage....the old two wheeled mistress, The next build I will get my son involved thats for sure.
