From Provo.org:

"May is National Bike Month and Provo is celebrating the many benefits of bicycling! Whether you bike to work or school, ride to save money or time, pump those pedals to preserve your health or the environment, or simply to explore your community – you’re going to love the events and activities we’ve got planned. We’ve put together a month full of events and activities to celebrate the unique power of the bicycle and the many reasons we ride!"

See this website for a list of all the events happening this month.
