The GOBIKE helmet with the safety warning light is a vital, strong, comfortable, and necessary accessory for anyone that rides an e-bike. Our helmet is manufactured with a strong Polycarbonate exterior shell (PC) and Expanded Polystyrene (EPS) interior shock absorbing material. The EPS foam is the choice for most bike helmets because it is lightweight, durable, and provides ample ventilation. Upon impact, the EPS is intended to compress and spread to reduce the force passed onto the skull, thus reducing the linear acceleration of the brain. The GOBIKE helmet consists of multiple air ventilation airways, front and rear LED lamps with various flashing warning choices, a USB connection to charge the warning lights on the GOBIKE helmet, and a head circumference adjuster to get the perfect fit!
