The high-wheeler lives on in the gear inch units used by cyclists in English-speaking countries to describe gear ratios.

High wheelers were derived from horse-drawn wagons, [3] and often were conversions of these. Similarly to these wagons, they often had wood-spoke wheels , suspensions, and boxy wooden bodies. The large-diameter slender wheels provided ample ground clearance on the primitive roads of the late 19th century, and frequently had solid rubber tires .
At the first Maricopa County Fair in 1884, Lucius Copeland demonstrated his steam bicycle, one of the first motorcycles, a steam-powered Star high-wheeler. It was claimed to have traveled 1 mile (1.6 km) in 4 minutes, at a steam pressure of 80 pounds per square inch (5.5 bar), and carried enough water and fuel to run for an hour.
