From SFBC:
Join the SF Bicycle Coalition, YBIKE and Sports Basement for an English and Spanish bilingual Bicycle Festival! We'll be teaching people of all ages to ride, setting up a bicycle skill building course, opening up our "Safetyville" city for bikes and walkers, and Sports Basement Bicycle Doctors will provide free bicycle check-ups and minor adjustments. YBIKE bicycles are available for loan at the event.
Is your child's bike too small or do you have a bike that's not getting the use and love it deserves? Come for the Community Bike Swap Event from 10am-12pm and exchange or donate it (please bring complete bikes only.) The SF Bicycle Coalition will also be running the popular "On Road with Your Child" Family Biking Course. RSVP here for On Road with Your Family class, Bike Swap or Learn to Ride.
