I've yet to notice any difference - no change in the cycling behavior of the general public or police actively trying to catch offending cyclists.

I think most of the 113 cycling infractions were already technically illegal, but now police can issue fines under the "blue ticket" system.

Fines are not paid on the spot though, so be warned. There have already been instances of scams where fake police have caught an unknowing cyclist breaking one of the now ticketable laws and demanding a fine be paid on the spot.
