I like the free wheel ratchet... I'd have thought he'd cut some holes into the wheels?

Hi Del.

If you ever visit the Science museum in Birmingham you will see a bicycicle made completely of wood by an African boy in 1917. The only part that is not made of wood is the chain, this is made of a leather thong in which he has at regular intervals made knots!

Cheers...I remember my Father in Law (sadly dead now) saying he'd seen such a thing in India....

A very interesting project, thank you.

Now all we need is to use re-cycled bamboo for manufacture, and it would be both carbon -neutral and eco-friendly at the same time.

I remember Scientific American magazine, back in the late 1960's, showing energy efficiencies of various transport forms.

The cycle won as most efficient, far more efficient than walking.

Kind Regards....

Hi Sparky.

Near to where I live is the city of Birminham, this is a city of two million souls and very difficult to traverse in rush hour. So last year the council arranged a race to across the city, four people were given this task, one on a bicycle, the second in a car, the third by metro and a fourth by buss.

Needless to say, the train came first with the cyclist second, the motorist came last! Now all of a sudden the rush hour is full of cyclists.
