We always recommend that you wear a helmet. Some cities require it by law. Hard-shelled helmets provide much more protection than styrofoam helmets, especially in high-speed impacts. If you get into a collision, the helmet's integrity is compromised and cannot be reused.
Some Social Bicycles systems provide helmets. You can find out more information on your local bike share website. If you'd like to purchase your own helmet, we offer a discount on all Bern helmets to our users.
