Is your bike ready for summer? Join the Des Moines Bicycle Collective for a tune-up workshop as we celebrate National Bicycle Month. We will cover the ABCs (air, brakes and chains) of basic bicycle maintenance in this fun and interactive workshop. Bring your bike to the South Side Library’s parking lot for a program of instruction and assistance. All ages welcome! Riding to the program is encouraged and there will be a chance to win a tire pump for your bike!
