I had never heard of a Trailmate Joyrider until the other day when one popped up on the local Craigslist. It was cheap and I didn't have one - so now I do. I aired up the tires and rode it today. It rides well except I can tell the rusty chains, (there are two), create some extra resistance. I plan to restore it. Anybody else got one? I believe this one is a '93 model.
