[n 1] The original Naismith's rule from 1892 says that one should allow one hour per three miles on the map and an additional hour per 2000 feet of ascent. [1] [4] It is included in the last sentence of his report ...
Air resistance increases greatly as speed increases and is the most significant factor at speeds above 10 to 12 miles (15 to 20 km) per hour (the drag force increases in proportion to the square of the speed, thus the power required to overcome it increases in proportion to the cube of the speed). [18] Human factors can also be significant.
High-performance tires are rated for speeds up to 168 miles per hour (270 km/h) and ultra-high-performance tires are rated for speeds up to 186 miles per hour (299 km/h), but have harsher ride characteristics and durability. [32]

Carrying capacity is also optimal at a width of 3.0 to 3.1 metres (9.8 to 10.2 ft), both for motor traffic and for bicycles. [8] Throughput is maximal at 18 miles per hour (29 km/h); as lane width decreases to 3.0 to 3.1 metres (9.8 to 10.2 ft), traffic speed diminishes, and so does the interval between vehicles. [8] [9]
