Urban growth leads to new alternative mobility systems such as bicycles, scooters and motorcycles among others.Their regulation is ambiguous and access to these means of transport is free for anyone with a smart phone. However, these companies do not provide any security system for users.Thinking about how to solve this problem, we devised a helmet that was accessible, of temporary use and could be disposed of without guilt.To develop this idea, we partnered with Polybion, a company that developed Fungicel, a patent that uses Mycelium. A fungus that develops as a foam. Providing cushioning at the time of an impact.
