The League of American Cyclists is once again promoting May as National Bike Month.
They have lots of information on events and how to promote them in your area.
Some of my favorites are:
(1) refresh stations
(2) ride with the Mayor
(3) guided rides on local routes
Where I work in Cary, NC there are various signed bike routes and a system of greenway trails. I think it would be great to have ride leaders to take small groups on the routes. This would show people some nice places to ride and let them discover some routes that could work for running errands.
What kind of Bike Month events are being considered in your area?
