As biking becomes increasingly popular thought and design innovation is pushed to a new level. Here of some of the designs around the web that caught our eye.

The Plus Bike designed by Fabio Bortolani and Ermanno Righi. Fixed gear with lights built into the frame. [via Toxel].

2009 SE Bikes not only look good but allow you to change your fixed gear to a mutiple gear quite easily. [via thedigitalx]

The Plug Racer by Charge bikes. Simple design, clean frame and red chain. Love it. [via Charge]

Custome designed bikes from Fast Boy. I love the hadlebars on this one – again clean and simple. [via FastBoy]
