Bike brand Pedalfactory has just released the “Sandwichbike” – a do-it-yourself flat-pack wooden bicycle you can make at home. Developed in Germany, “Sandwichbike” comes as a kit in a compact cardboard box, and can be assembled with a few basic tools in less than 30 minutes. Comprised of 19 components including two beech plywood plates that make up the frame, each piece is securely held together by a series of carefully-milled aluminum parts. Extensive tests were carried out by compressing the seat, structure and wheels, and bottom bracket up to 100,000 times, simulating everyday wear and tear.
