An odd article today in the newspaper:
It talks about 50 year olds who are too confused by gearing on bicycles and intimidated by the spandex crowd. The bicycle companies have detected these people want to have simple bicycles for playtime, and have come up with a bicycle that detects how fast you're riding (with a computer in the front wheel) and it automatically shifts the gearing for the rider.
Seems the next step for such people is to add a small motor and battery pack. One can only hope the bicycle companies will detect that logical conclusion.
