Hi all. I literally just got into this maybe a couple weeks ago and want to build by own motorized bike. I've heard that a weed whacker engine would work best, is this true? If so, is there a resource to show me how to install it? If not, what's the best option?
Welcome to the forum, a Do It Yourself would not be the easiest build, buying a kit would be. Depending on where you buy the kit the cost would be between $100-$200 for everything needed except the bike. All the instructions for a kit can be found here on the forum.
By the time you buy sprocket, chain and hardware to build it you will be half way to the price of a eBay kit. Here's a example.

Here's a 50cc kit. Actually 48cc but is advertised as 50cc.
