I don't think today isn't a "bike boom', but more of an expanding market. Also the e-bike thing is becoming more mainstream and will increase general (and therefore c & V) interest along with it. While the e-bike expansion is now focused on off-road and sport riding, the expansion into more general daily use will bring strong growth to all the bike markets and those folks will add a lot of new buyers to "usable collections". And yes, I shamelessly admit to justifying my serious N+1 addiction and the profit motive when I begin selling them off at age 96.

Hey,,it's a solid thirty-year plan....
