King County and the city of Seattle require that all bicyclists wear helmets. Bicyclists can be fined $80 for not wearing a helmet.
To promote safe (and law-abiding) bicycling in King County and the Puget Sound area, Cascade Bicycle Club sells affordable helmets at community events, including Bicycle Sunday, throughout the summer.
We offer helmets in all sizes from toddler through adult XL. Helmets are $15.
