I'd definitely look for a cheap used MTB to steal the handlebars, shifters, front shock forks, wheels tires off from. Those skinny tires will make for a very harsh ride @ 30 mph.
I'm going to play with the suspension once the engine is installed and move from there. For now, I want to focus on the necessary changes to create a simple motorized bicycle. Thanks though. I'll definitely keep that in mind post-engine installation.
