chainsaw bike

[turbofiat124]

Im going to find an old bicycle and slap a chainsaw powerhead on it....have not figured out my drive system yet though .....suggestions?? This is going to be my first attempt at this

I know this takes all the fun out of building a custom made from scratch setup but why not use one of these kits? I have seen them for as low as $50 from one supplier (not Ebay).
