Re: bicycles non electric

Airless bicycle tires? I hope they're better than the things I remember as a kid...

  I remember these hard yellow & orange 'rubber bands' (as we called 'em) that we used to stretch over the skinniest of rims back when I worked at the bicycle shop.

  This dude (with the skinniest legs I had ever seen on a man) would go through a set every few weeks/months.  I remember trying to ride that bike one time, and it was the most painful, teeth jarring experience I think I ever had.

  The owner explained that the solid front tire was more efficient because it didn't deform and waste energy. ( I was 11-12 yet he explained stuff as though I was an adult... fond memories) (and yes I 'worked' the shop at 11-12, I suppose you'd have to call it apprenticing, but we weren't being explioted, and it was a great experience!)
