The helmet problem for city riders has never really been the helmet — it is having somewhere to put it once you arrive. FEND's patented Smart-Fold design collapses by half, so it goes in a bag or backpack instead of hanging off a handlebar. It is designed and engineered in New York, which shows in what it prioritizes. Features Patented Smart-Fold technology folds the helmet by 50% Removable front and tail lights, 30 lumens, visible from up to 800 meters Three light modes — steady, pulse and flash — with up to 5 hours of runtime USB-C rechargeable IPX6 water resistance rating Dial fit system Specifications Sizes Small, Medium, Large Colors Ultra White, Carbon Black Certification US CPSC and European EN1078 Light output 30 lumens, front and rear Runtime Up to 5 hours The EN1078 certification covers bicycles, skateboards and e-bikes or scooters ridden under 20 mph. For faster vehicles, a full-face helmet is the better choice.
