Stinger is a concept bike which includes nearly every available ecological niche that a traditional bike generally lacks. The main difference between conventional high-emission bicycles and Stinger is, this bike is helping the environment by keeping it pollution-free by using fuel cells. Moreover, renewable resources were used to make the adaptive, versatile and eco-friendly bicycle which would be a true alternative to traditional ones. This bike is very much adaptive and robust just like an insect that can adapt the narrow space situations of metropolitan areas. Considering the functionality, stinger is neither a scooter nor a motorbike – it combines the assets of both.
