STEM is a lightweight and small vehicle concept aimed for urban use which is ideal for short distance rides like commuter traffic, shopping-tours or the way to work. This three wheeled city-vehicle is a perfect alternative of the traditional cars that are being used in the city area. This vehicle has a modular case located in the front side of the vehicle which can be used as a storage unit for small and light loads, moreover, you can remove this if you want. STEM is envisioned to be publicly used and therefore, an additional rental station infrastructure has also been developed where people will be able to rent this vehicle for short period of time from all over the city. When you will reach your destination, you can return it to another rental station that is nearest from where you are.
