Wheels changed how the load was carried
A rickshaw’s wheels supported the passenger’s weight, so the driver did not have to lift the whole load with every step. Instead, the pull on the shafts—the long handles attached to the vehicle—kept it moving while the wheels rolled beneath it. That was a major mechanical advantage over carrying a person, but it did not make the passenger’s weight disappear: the driver still had to supply the force that moved the loaded vehicle.
Every start and slope demanded more
Once rolling, a rickshaw could keep moving with less effort than would be needed to drag the same load across the ground. But the driver had to work harder to get it moving from a stop, because the vehicle and passenger had to be accelerated together. A hill added another burden: gravity pulled the load downhill, so the driver had to exert extra force uphill and control the vehicle on a descent.
Road conditions mattered, too. Firm, smooth ground let the wheels roll more easily; rough or soft ground made them sink, jolt, or meet obstacles. The wheels eased one part of the task, while the driver’s legs and arms absorbed the rest through repeated steps and sustained pulling.
A ride built on human effort
The vehicle’s comfort for its passenger depended on a simple transfer: the frame and wheels carried the body, while the driver provided the motion. A smooth ride therefore did not mean an effortless journey. Each block traveled was the result of human work transmitted through the shafts to the wheels.
