Re: help a noob out.
Im also a noob to the hobby. Youll find that there are several dealers on ebay for kits. If you look to sidebars of this thread you may find a kit. If you are interested in speed thats doable as well.
I want to forewarn you that these modifications to a bicycle will make it as dangerous as a scooter/moped if not more. It only took me 4 days before eating pavement.
You still get the benifits of bike riding though. I was surprised after my first ride to find that my legs had a small burn from peddling. In a way you still get your exercise while having a cheap fun way to get around.
For speed parts look up Andyville and Sick Bike Parts(Pablo). Search the forum well, the info you seek is here.
