It only costs Izhar Gafni 9-12 USD to produce this sleek, waterproof and roadworthy cardboard bike. At the behest of his wife (who was tired of Gafni’s talk without action), the Israeli Kibbutznik developed an earth-friendly alternative for urban cyclists that is “so cheap it’s not worth stealing.” Like most innovators, Gafni defied the naysayers who said it’s impossible to make a bicycle out of cardboard in order to realize this creation, though the journey was not without its pitfalls. Check out images taken from Giora Kariv’s six-minute film that demonstrate what a cardboard bike is made of.
Gafni experimented with several prototypes before coming up with the winning design.
Made out of corrugated cardboard sheets, the bicycle can withstand up to 140kg.
In some cases, the cardboard is rolled up to give it strength.
Engineers told Gafni it would be impossible to build a bicycle out of cardboard, but he persevered (at his wife’s behest.)
In Israel, bicycles are regularly stolen. Gafni’s design is so cheap that it’s not worth stealing, he told local media.
Early prototypes looked like delivery boxes on wheels, he said. But the final design, for cardboard, is pretty darn sleek. At least we think so.
This is definitely not a winner!
But this one is.
Although it costs only 9-12 USD in materials, Gafni sells his cardboard bike for USD 60; still, that’s a steal for a simple whip around.

Has a single journalist ridden this prototype bike? No. Wonder why? Because this is a lousy bluff. Just look at that rear brake lever that has no corresponding cable or mechanism. The front brake wont work either. Typical brakes squeeze a wheel rim with a 500N force and over 2MPa pressure. That would crush or tear any cardboard wheel. Look at those conventional pedals that are meant to screw into cardboard: They would just fall off! So the cranks cannot be cardboard. Nor can the wheel dropouts, nor the bottom bracket. Look at that valve that “inflates” one of the the solid tires. Look at the flimsy belt drive! Why don’t other bikes use thin belt drives? Because they aren’t strong enough for any real riding. So when an independent reporter tests this thing, we can look again. For now it’s a cute art project, not an industrial design. Besides, just the front brake costs more than $9. And is cardboard coated with a strong polymer really so easy to recycle?
IN THIS THROWAWAY WORLD, YOU FOOLS WILL USE IT ONCE, THEN THROW IT AWAY……..into the re-CYCLE bin, of course.
Well better a cardboard bike than one made from metal.
Would really like to Contact Izhar Gafni about one day distributing his bikes in my town of Davis, Ca.
We have lots of bike trails and bike commuters including thousands of University students who would love an inexpensive bike.
I cannot imagine regular bike shops trying to sell these cardboard bikes next to their expensive bikes selling for hundreds if not thousands of dollars.
About ready to retire from my thirty five year Chiropractic career.
I would love to start something new. Exciting!
Help me contact Izhar if you have his email address?
Thanks
Man, I want one. How, when and where
where can we go to buy this great invention, is there a market for it…
Looking for further reinforcement, durability and mass reduction with very little marginal environmental impact, Gafni? I am sure we could help.
When and where will these bikes be sold.
Is a great ides.I am interested
Has
Gafni heard of the proposed cardboard Cathedral plan for Christchurch
N.Z.to replace one destroyed in an earthquake ?
He may be interested in supplying a bike to further demonstrate.
Maurice, there is something to your criticism. But in the long run, these bikes are using very little in terms of material for construction. They can’t be compared with a ‘real’ bike – not in price, environmental foot print, nor performance.
Maurice, Gafni’s invention is definitely low-carbon as compared to bikes made of metal and plastic.
How much glue or resins were required to make this thing? These substances are definitely not green; and cardboard isn’t either, for that matter.
The bikes aren’t on the market yet. We’re all waiting for them!
Yes, how do I buy one!?
I live in Tel Aviv and would love to have one. Is Izhar selling them?
Jen, I suggest taking as close a look as possible at the video, to judge the comfort of the seat. And Eli, the same video shows Gafni rolling right through a puddle without a care in the world.
Great idea, just wouldn’t to ride it through a big puddle, or get caught in a rain shower!
amazing!!! any word on how comfortable the seat is?
