There is more to it than throwing on a pair of shorts & helmet and hopping on a bike for a spin.
As already mentioned, elicit assistance from your local businesses. Check with the majoy bike manufacturers, but I think you will have better luck with the local route, as it is THEM who will benefit from the presence and it is with THEM that your department has a rapport.
Also, get verified or you will have to change the name. We don't just take people at their word around here when they say they are the police. FWIW, it is also often regarded as poor ettiquette, making yoru first post to ask for something. Try the rapsheet section... introduce yourself.
