What a cool concept bicycle! Look at this thing! In particular the rim drive makes for spokeless wheels for such an unusual look. It's just great to see so much creativity in bicycle design. No center bar so reasonably well dressed people don't have to kick their leg up and over. This is a problem with TPP's BikeE where the chain comes just too close to your pant leg to allow you to wear anything but shorts unless you like dark grease stains.
