There is a high level of air pollution nowadays in Hong Kong. The pollutants are given off from motor vehicle exhausts which are known to damage health. These pollutants are often produced when the car engine is not working efficiently and Carbon Monoxide is producd as a result.

We therefore design an Electric Tricycle, which uses less energy and limited resources and does not pollute the environment, for people to enjoy their leisure lifestyle in the 21st century.
