Our local TV news had a story last week about "you can't buy a bike because there are no parts to build them." I figure that's enough for the hoarders to hang onto the bikes they bought last year for another summer. And then there's no sense selling them in the winter, because who rides bikes in the winter?
There'll be a spread, as there always is. Fastidious housewives will force the sale of a few bikes next summer. Peak CL sales are probably 5-10 years away, tailing off for the next 30-50 years as people die or move into assisted living homes.
