With growing bike popularity, a number of accidents is increasing too. With this in mind, product designers and engineers put many efforts in developing safety bicycle helmets to protect the brain and neck of urban riders and athletes in the event of a crash. To do this effectively, helmets must be made of a crushable material to absorb the collision forces and a strap system to make sure the protection stays in place. The exact design of a helmet depends on the needs and specifications of the user and may vary from a simple paper structure to a revolutionary high-tech device.
