There should be a recording of the telephone exchange between the officer and the station, I would think.

A visit to the patrolman's commander, armed with a written account of the incident, citations of relevant law, and the exact date and time of the incident so that the recordings can be tracked down, might be productive. You could end up with the citation tossed out, an apology from the commander, and a promise to set the patrolman (and the rest of the unit) straight about the law regarding cyclists.

That might be more worthwhile than a trip to court, especially since I'll lay you 10-1 odds that if you choose to fight the citation your hearing will be dalayed (at the officer's request) multiple times, in hopes that you'll give up and go away.
