Shipping fully assembled bikes is expensive. So the people behind the Sandwichbike ($TBA) decided to ship their bike in pieces. The result is a new take on the bike, built from a "sandwich" of two weather-coated frames of plywood, bonded together with "smart cylinders" and designed to be both rugged and good looking. Thanks to this unique design, the bike comes flat packed with everything you need in the box, including all the tools and the less-than-50 parts. The only downside? You can't get one just yet — but they will be available later this year.
