We just returned from a week in Aspen, Colorado. Like Miami's South Beach, Aspen is a bike town. Unlike South Beach, those vintage "beach cruisers" have been pimped to extremes. I'm glad I don't live there, because I don't have room for all of the vintage bicycles I would buy just for their awesome-ness.
We also saw a few of these wild and crazy outdoor elliptical bikes or ElliptiGO. You can buy one for $2199.
