Are solid rubber bike tires ok?There is a reason that the inflatable tire has dominated since it's invention by Dunlop. Materials are getting better but they still don't provide the combination of strength and cushioning of the inflated tire.
...
the pneumatic tire solves LOTs of bike problems
cushioning
traction
light weight
comfort
cheapness
now think about solid tires over rocks and roots
uugghghhhh!!
...
I haven't ridden them but people I know and trust have and they all say that they are terrible. They give a rough ride and they get poorer traction than a pneumatic tire.
...
Solid tires are awful. They weigh a ton and ride like they were made of cast iron. There is a very good reason why 99 .99% of bike tires have air inside
...
You cant beat pneumatic tires.
Can you imagine attaching a pedal to a crank made of this stuff?SeaGypsy wrote:Rattan dressed steel.
Meet the inventor of the world’s first cardboard bike
Nobody believed it would work, but an Israeli cycling enthusiast thought otherwise.
Izhar Gafni is crazy about bikes – he makes them, fixes them and rides them. But three engineer friends thought the chain had really slipped from the gears when Gafni suggested crafting a cheap and environmentally friendly bicycle out of cardboard.
He had been inspired while working in California on a pomegranate project, and one day saw a car outside a bicycle shop sporting a wood-frame boat with a cardboard cover.
Gafni started testing and building, refusing to accept the engineers’ opinion that the project would never work. Israelis, he reminded them, “did impossible things with agriculture, with military, with high-tech and science. I thought, if they can do it, I can do it.”
Gafni has built six prototypes of 100 percent recyclable materials, 95% percent of it strong cardboard. He sees it as a possible urban environmental project or perhaps as a mode of transportation for schoolchildren in Africa. He is hoping the worldwide publicity for his project will win his cardboard bikes corporate or governmental sponsors.
