I'm a classic vespa builder/racer, a cyclist and rat-look patina'ed splitwindow kombi owner.
I'd long thought about building a vintage bike with a cut down smallframe vespa motor in it thinking it would be fairly original then when searching for bike frames discovered this whole world of people already doing just that and better and more, and with so many cool parts and frames and tires and vintage board-track rat-look badness..... so it's all right up my nostalgic alley ways... hmm that sounds a little dodgy. Anyways mighty impressed!
I'm amazed at the stuff you guys build and if/when I do get into building a motorized bike will be sure to show and tell. and proabably ask stupid questions too.
