We manufacture one of the best electric motors for fans and electric machines.
Its about availability of raw material and skills. We dont have special steel required for internal combustion engine but we have plenty of copper and it is cheaper in Pakistan. Furthermore, we do have semi skilled worker in the field as well.
Need of the day is to form a proper company and do some R&D and designing. We already have lots of experience in amking chasis of Chinese bikes. Now we need to work on designing the power system. The key challenge with the electric vehicle is the range, heating of electric storage device and charging. If you can come up with these issues or buy the tech, you can easily mass produce them as they dont require specially alloys for engines.
