I saw a guy riding one of these on the road today. I had to play around with google searching until I found out what it was.

Getting that low-impact elliptical workout and being able to go outside to do it seems great, but I think I'd be terrified to ride that down a hill!

Anyone else seen one out on the road or know anyone who has used one?

I'm just curious...I'm not planning on buying one!
