Velocipedes (cycles) had wheels of increasingly disparate size, with the front growing ever larger than the rear. Notable were the high-wheelers, or penny-farthings, a version of which Starley made with William Hillman. Their Ariel vehicle was all-metal and had wire-spoked wheels, much lighter than wooden-spoke ones. Tangent spokes were ...
The vehicle had a wooden carriage that rode on "superior Western wheels" and was a dramatic improvement over earlier modes of transportation. Whereas the earlier sedan chairs required two people, the rickshaw generally only required one. More than one person was required for hilly or mountainous areas.
