The wonder rickshaw is slightly different from the normal conventional rickshaws. While the present rickshaws have a chassis that is horizontal, and acts as a load to the puller, the wonder rickshaw chassis is 10 degrees to the ground leaning to the front. Thus any load would actually act as the propulsion and all the forces combined would require less power from the puller when the vehicle starts moving. The current chassis is fixed in all the three points with a triangular fame but with the new vehicle, the chassis is hinged at the pedal hub and the two other points are fixed with the frame. Explaining, Ghosh said, “Since the hinged point acts as pivot, the shock generated by the road is transmitted as a force to the frame and makes the hostile road favorable to the puller.”
The weight of the passenger in the current rickshaw falls directly on the axle but in the wonder vehicle the seat frame will be tubular and the rear two legs will not swing and remain pressed to the bearing box horizontally, converting the downward passenger load to horizontal forward propulsive force, as reported by NDTV. This means, more the passenger weight, more is the push.
Ghosh, who currently works as an assistant general manager with Shriram EPC Ltd, said that he is an innovator and not an entrepreneur. He has invented a good machine but he cannot replace the existing million rickshaws or manufacture any, and would require the help of a good cycle and rickshaw manufacturer to do the honours. He is hoping that his design would be looked into by the state government so as to decrease the plight of the rickshaw pullers of our country.
