Oh, so the chain is totally enclosed? That's making it more like my shaft-drive bike, then. And you shift gears by twisting the handlegrips? Does that make it less likely that you'll throw a chain?

What is a free radical?

Thanks for the pricing info, Mimosa! My husband's family is from The Netherlands and he's been wanting to go there. (Well, the first one over with his surname (though it has changed drastically) came to New Amsterdam in the early 1600s!) If they'd kept the surname it would be Lubberdink. I'm kind of glad they didn't!
