If you like fixed wheeled cycles, great! But this piece uses statements that depend on a survivor bias. Eg, those who stick with a fixed wheeled cycle will be stronger than those who do not. Perhaps it's true - it gives no real evidence - but what of all those who would give up cycling if not for gears?<p>It makes the the unsubstantiated claim made that "Keeping your legs in motion keeps the muscles supple, and promotes good circulation." On my long trips I'll often stop to read roadside sign or historical marker, or look at something interesting. Are my frequent stops also unhealthy?<p>If taking a break from pedaling is so unhealthy and leads to unsupple legs and bad circulation, then maybe I shouldn't bike at all, and stay home?<p>Because fixed wheel or not, the fun for me is to see what's out on the road, not "feel a closer communion with [my] bike and with the road".
