Phil Bridge built the prototype of a cardboard bicycle in 2008 as part of a three-year product design degree at Sheffield Hallam University . The cardboard bike was made of a honeycomb-shaped reinforced cardboard with the trade name Hexacomb and could carry a rider weighing 77 kg. The drivetrain and brakes were made of metal like a conventional bicycle; it was also equipped with conventional bicycle tires.

It was waterproof, but only designed to last 6 months of continuous use. The use of cardboard should prevent theft.

Izhar Gafni, an Israeli mechanical engineer and Bike enthusiast, applied in 2009 for a "bicycle made of recyclable cardboard" a US - patent . In 2012 he presented the prototype, which he had made almost entirely from cardboard in his workshop in Moshav Ahituv. The components such as the bicycle frame, wheels, handlebars and saddle consist of folded and glued cardboard. The complete bike weighs 9.1 kg and is flame retardant and has a water-repellent coating. Gafni reported that it carries riders up to 220 kg. The cardboard bike has solid rubber tires made from recycled car tires . The drive from the pedals to the rear wheel has a rubber toothed belt . Gafni and a business partner are planning to mass-produce cardboard bicycles and sell them for EUR 18 each with material and manufacturing costs of EUR 8 to EUR 11 . The target market are low-income countries.

The prototype was exhibited in November 2012 at the Microsoft ThinkNext event in Tel Aviv . Gafni tried on the Indiegogo crowdfunding platform to find donors worth $ 2 million to finance the project. However, on June 25, 2013, he had only acquired $ 10,000. The campaign ended after raising just $ 40,107 in total.
