Not really. It's corrugated paper. I worked in a corrugated paper factory and if I ever called it cardboard, I was immediately corrected.
I'd like to ride one to see whether it rides like something as cheap as it is. It won't have to be much to deliver more than it costs.
The baby sucking on the pacifier bit really enhanced the Homer Simpson quality of the project.But Homer's do-it-yourself projects always fall apart.Don't know why, but this brings to mind the new South Park episode about Honey Boo Boo. Honey Boo Boo is destroying Cartman in the ratings!
I don't know exactly what the advantages are. A basic bicycle is one of the cheapest, most economical things on the market today. You can by a 10 speed brand new assembled and delivered for $50. Most of the materials are already recyclable, and they can last decades.Overcoming the challenges of this concept is admirable, but I don't know if it has a practical use. It would be great as far as how easy it is to dispose of. On Christmas morning you get a new one, and put the old one in the fireplace.
Isn't it actually a wooden bicycle?
What happens when you hit a bump? Is the wheel ruined?Also, I just don't believe that could be made for $20... not unless it looked way rougher than that and didn't have brakes and gears.
You can by a 10 speed brand new assembled and delivered for $50.Used ones are even cheaper. And plentiful.
Surely the brake lever, caliper, housing, cables, etc. and the tires and tubes would cost far more than $20, even if the rest of the bike cost zero.
EMD said... Used ones are even cheaper.The Supreme Court might soon add "for now" to this observation. I can't imagine how they could be even considering modifying the right of resale on used good but they're about to take up the question.
Actually, if we had a cardboard President, he might do better.

It's why the cardboard box replaced the wooden crate.What the builder has left out of his summary is the fabrication time, which is bound to be considerable, probably much more than would be required to build a bike from welded steel tubing. The cardboard bike is appears to be covered in polyurethane to make it waterproof and to add stiffness. Polyurethane is more costly than enamel, and more labor-intensive to apply. Therefore I question the claim that the cardboard bike is cheaper than a conventional bike.Regarding Ann's point (What happens when you hit a bump? Is the wheel ruined?) mostly likely the wheels cannot withstand the same impact that a conventional wheel with steel spokes can endure. While cardboard is remarkably strong for it weight it is not resilient. A cardboard spring would be a totally failure.
Parts of the cardboard bike that aren't cardboard:1)Handlebar2)Braking system3)Bearings4)CranksThe guy has a thick accent so I didn't catch everything he said but I think he claimed that his transmission was also cardboard, at least the sprockets.
I would never have told him it was impossible. Never. I would have showed him any number of ways to structurally adjust cardboard to support load and stresses. Those engineers that told him that are morons and should kiss his ass daily for being morons and being wrong.
Why does that child still have a pacifier in his mouth?

Rusty, I don't see your $.35 price. I buy tens of thousand of boxes every year and $.35 won't get you a quality box the size of a bread box, whatever that is.

The box you buy goes through a couple of middlemen before it gets to you. Evderybody tacks on their percentage.If he uses an abrasive airjet cutting system he can pump out hundreds of frame blanks an hour for just a few cents. It's an economy of scale. Unless he can automate assembly, labor will be his biggest expense.Economy of scale is how they can sell a Bic pen for .25 and still make a profit.I worked in an industry than ran quatities of metal parts from a minimum order of 5000 up to 250,000At 5000 a part might cost .18, but if the client ordered 250,000 the cost would go down to maybe 3.5 cents for the same part.
