“Made of plastic” is not the only characteristic of the Izzy Plastic Urban Bike, a collaborative project between Omer Sagiv and Uri Sadeh. One would expect a fragile vehicle but the bike is actually quite firm to bear the weight of two adults (quite impressive huh?). Best of all, its frame is recyclable, which means that you can have the damaged frame replaced at the store. To top off the cool concept, the bike also incorporates 2 free standing locking systems, three-dimensional illumination, and the integrated rear suspension.

But does the “completely plastic design” also means the bikes could be easily burned to ashes? Hopefully not.

Anyway, the bike looks great and the recyclable plastic is a meaningful nice design. Let’s just wait to see this bike hit the market soon, and looking for some more details.

This is one wisely designed gorgeous bicycle! If you need an electrical bicycle, or a lightweight bicycle and you might still need it to be eco-friendly? Well, what you want is rightly the Carbon Fiber Electric Bike by Ralf Kittmann. The concept bike adopts the carbon fiber—which is highly conductive—to take the place of wires as a power distribution network. So when the electricity is generated from the special electric installation built inside the frame, it will be transferred to power the motors between the rims and the lights. That energy will also be used to drive the system to turn the wheel, by using a counter-turning axel in lieu of gears and chains.

OK, this is it. Do you love it? It’s beautiful and elegant, and also eco-friendly, the only flaw I can find is that this can’t work manually, so if the electricity went out we’ll be stuck, and we’ll lose a lot of exercise while using this instead of a traditional bicycle. Nonetheless, sitting on a bicycle seat is already more exercise than sitting in your comfortable little car, and in addition, we can got much more fresh air on the way!
