It's not quite that simple. This has been discussed at length on the bikeqld mailing list. If you want more info the thread starts here.

Basically, the root of the problem is an inadequate detour around a construction on the path, and some cyclists are choosing to ignore the advisory 'cyclists must dismount' signs. All a storm in a teacup imo, but of course a couple of vocal local yokels pipe up, and some newsertainment host decides it's time for another 'cyclist rage epidemic' story.

I registered my opinion by neither watching the show nor responding to their rather clumsy and clichéd troll.
