The name tuk-tuk stems from the rather rough sound of the early models. The single stroke motor powering of the first three-wheelers had a distinctive hum when the engine ran, and this "tuk-tuk-tuk" became a familiar sound to many in need of quick and convenient transportation around bangkok. Since its first appearance on bangkok'city streets, the tuk-tuk' technology has improved dramatically. Its small size makes it suitable for driving down alleys. It has a great ability for tight turns. And much more than simply a convenient mode of transport, the tuk-tuk has become one of bangkok's most recognisable symbols, and is a great way to explore the city.
