The Scuddy electric scooter weighs around 28 kilograms and when folded up is about as big as a water crate. In just a few steps it can be converted into a swift, emission-free means of transport. Those who want to take a bus or tram back can transform the scooter back into a small cube in a jiffy and take it aboard public transport free of charge. The green electric scooter was developed by two mechanical engineering students in Kiel.
