I rode my old ('88) Trek 820 Mountain Bike to work last night instead of the Volae Tour.
It was kinda fun. The center of gravity seemed a bit higher and it sure feels kinda funny sitting a waaaay up there on top of the bike like that.
But ya know, it was kinda fun. These "Uprights" may be quaint and silly looking....but they might just catch on some day (of course not for any serious cycling).
