Re: Is this Cool or what
The ebay listing you popped up there would only look like a ring of light if you go very fast, I tried strapping a glowstick to my wheel to see if it would spin fast enough to look like a circle, but it didn't. You need a few around your rim to look like that.
As for igniting the gas coming out of your muffler, it will work. My muffler broke once, and the end got hot enough to glow after about 60-90 seconds of riding, then it would spit fire. Needless to say, I got a new muffler quick.
