Is ‘cavalcade’ the plural for cyclist?

Michael Alexander sees something curious from his balcony:

I’m not certain what set off this cavalcade of cyclists rolling for over 15 minutes past the Roundhouse. I expect it was associated with the celebratory takeover of David Lam Park a block away, where a few hundred cyclists ended their ride from Seattle. Food, music, (heavily filtered) sun, and a parade.

What’s not to like? I bet mayoral candidate Wai Young can think of something, like having the event but banning the bikes.
