Bikes with suspended seats already exist, but none as pretty as these. Sure, it might be more for the laydeeez in the house, but it'd certainly be a talking-point for whoever rides the thing.
Created by the Dutch Vanhulsteijn, the two or three-speed bikes start at 1,495 Euros ($2,110), and look to be pretty customizable in terms of what you can request it to look and ride like. I'll take the blue one, alstublieft. [Vanhulsteijn via NotCot]
