"Electric Tuk Tuk" Zero Emission Vehicle
The first prototype of Sam Lor (Three Wheels Vehicle) has been invented by Mr. Lern Pongsopon in 2476 B.E. (1833) from modification of bicycle and rickshaw. It is become commercial vehicle to Thai people for long time.

In 2503 B.E.(1960) using of man-powered Sam Lor was prohibited in Bangkok Metropolitan Area (BMA). Since then, the engine powered three wheels vehicles (lorry type) from Japan was modified to Tuk Tuk (passenger vehicle type).

Although, Tuk Tuk is most convenient vehicle in general purpose. But, because of its powered by two stroke gasoline engine type which is more capacity (350-550 cc.) comparing to motorcycle. Tuk Tuk became to be main source of noise and white smoke (including unburn hydrocarbon gas from fuel and lubricants oil). To solve these problem, USAID of USA (including Electric Power Research Institute and Advance Electric Car Technology), USAID (Thailand), Pholasith Tuk Tuk Company Ltd. and Pollution Control Department jointed to issue “Thailand Electric Tuk Tuk Demonstration and development Project”. Its purpose to study, test, develop and demonstrate Electric Tuk Tuk(ETT) in Thailand.

This project started in 2537 B.E.(1994) and continue until now. From the first prototype of ETT which was developed from convention Tuk Tuk and continue improved to reduce weight and increase its performance and safety.
