In reply to S.Foi. Well better a cardboard bike than one made from metal.

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.

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

Looking for further reinforcement, durability and mass reduction with very little marginal environmental impact, Gafni? I am sure we could help.

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.
