CCTV now has the Festival of Lights video up! There was a great turn-out. You can relive the bike float here. To view it on the CCTV site, go here, and from the 2009 listbox, select the "Festival of Lights Parade." You can see the bikes at about the 43:00 mark.
(Sorry for the crappy image - couldn't get the screen capture to work on the streaming video.)
