Too bad it actually makes your tricycle sound like the gears of hell grinding souls into oblivion. Is that what bikes used to sound like??
I'm not gonna lie, when I was a kid I had two crushed can's on each wheel of my bike and a full deck worth of cards hitting the spokes and I would've probably bought one of these things also. I was a squid even when on a bicycle
btw, I got this video from a motorcycle blog. There's TONS of them, here's a site that shows you the latest posts on a couple dozen different motorcycle blogs so you don't have to search through all of them, I've found tons of cool stuff on there
