Cardboard bicycle

A cardboard bicycle is a bicycle composed mostly or entirely of cardboard. Only prototypes have been made as of 2012.[1][2][3] Reported benefits include low cost,[1] and construction from recyclable[3] and renewable materials.[4] The low cost is also expected to act as a theft deterrent.[5][6]

A cardboard bicycle by Phil Bridges

Phil Bridge's prototype

In 2008, Phil Bridge created a cardboard bicycle as part of a three-year degree course in Product Design at Sheffield Hallam University.[5][7][8][9] It was intended to discourage theft,[8] supports a rider up to 169 pounds (77 kg),[7] and is constructed from a structural cardboard called Hexacomb.[5] It is waterproof, but is only expected to survive six months of constant use.[5] The drivetrain and brakes are metal, as on a conventional bike, and it rolls on standard pneumatic tires.

Izhar Gafni's prototype
I.G. Cardboard Technologies cardboard bicycle.

In 2012, Izhar Gafni, an Israeli mechanical engineer and cycling enthusiast,[10] unveiled a prototype bicycle made almost entirely out of cardboard in his workshop in Moshav Ahituv.[2] The components, including bike’s frame, wheels, handlebars and saddle,[3] consist of sheets of cardboard folded and glued together.[1] The complete bike weighs 20 pounds (9.1 kg),[2] and is treated to be fireproof and waterproof.[1] Gafni reports that it can support riders up to 220 kilograms (490 lb).[10] It has solid rubber tires made from recycled car tires.[1] Power is transferred from the pedals to the rear wheel with a belt, also made from recycled rubber.[3] Gafni and a business partner plan to mass-produce a bike based on the prototype and retail it for 20 USD,[2] with a unit cost of 9 to 12 USD.[3] The target market is low-income countries.[3] The prototype was featured at the November 2012 Microsoft ThinkNext event in Tel Aviv.[11] Gafni has been trying to raise $2 million on Indiegogo to fund the project.[12] As of 25 June 2013, he had raised $10 thousand.[13] The campaign has ended with a total of $40,107 raised.[12]

gollark: Er, molten salt FISSION.
gollark: Why bother with molten salt fusion if you can just stick down a ridiculously expensive WHY-10000 fusion battery everywhere which needs power?
gollark: Doubt it.
gollark: There should be another really useful machine which processes in increments of exactly 117mB.
gollark: How odd.
