From LA Metro:
Bike Month is a national month-long celebration of the bicycle. For the entire month of May, we celebrate the two wheeler all around Los Angeles County. From group rides, workshops and community-hosted events; there is no shortage of bike related events. Bike Month is for everyone. Whether you ride for fitness, transportation or for fun, you can find an event for you and maybe try something new.
Metro helps produce two major Bike Month events: the annual Bike to Work Day and Bike Night. On Bike to Work Day leave your car at home and try commuting by bike with thousands of other Angelenos. There will be pit stops across the county to stop for a snack, coffee, and encouragement on May 17th, 2018. Join us at beautiful Union Station on May 18th for Bike Night, filled with food, fun, and bikes.
Many other organizations have events throughout May and we host a calendar and map of all events across the county. The calendar and map are updated at least weekly.
