My dad picked up a cool vintage bicycle and I have dreams of making into a motorcycle .Its got a tank and springer front end .

ebay

 

I've been lusting after these. The 3200 dollar price tag is kinda scaring me off though.

 

It's not a Simplex Servi-Cycle, is it?

 

Thanks guys ,The bike might get restored after all .Im only thinking about this idea ,Right now its sitting outside his house ,Rusting away .
