In the Saurashtra region of Gujarat, there are many chagdas, which are also known as ‘ta tas’. They consist of the front half and engine of a motorcycle and the rear half can be either a passenger compartment or more often a wagon for carrying goods.
Way over east in Shantiniketan (West Bengal) I spotted two kinds of three wheelers, which resemble, at least superficially, the chagda.
The ‘toto’ has the handlebars and front appearance of a motorcycle and the vehicle has a passenger compartment. The totos are very silent because they are propelled by electrical energy.
The ‘fohfohti’ which is used to transport freight is just like the chagda seen in Saurashtra. It is propelled by a motorcycle engine and its front half, like the chagda, is the front half and engine of a motorbike.
