On the thread topic, to me a bike is like a pair of shoes - i have a better chance of a good fit if I try it on first.

On the environmental thing, bandaids. Recycle cans and metals, be green ride a bike, protest coal plants, hug a tree . . . bandaids. The number of human beings on this planet is the problem, period. We are straining the resource, killing the aquatic life and poisoning the planet. Yay people! Rah, rah, rah! We're the best!

The solution to a problem often begins with determing the correct question. I suggest "What number of humans is comfortably sustainable on Earth and how do we achieve that number." I think under a billion would be a good place to start. Mother Earth will probably do it for us. The next hundred years will be ugly. Four horsemen of the apocalypse kind of ugly.

Current population about 7.3 billion. Projected to hit 9.7 billion by 2050.

Back to topic, Origami Crane 8 bikes on ebay for $350, supply limited. Seems like a good price for what it is, but will it fit you? Regards
