A pentacycle is a human-powered (or gravity-powered) five-wheeled vehicle.

Origin

The original pentacycle was designed and patented by the architect Edward Burstow in 1882.[1][2] It had a large central wheel directly driven by pedals like a penny farthing bicycle, with a "bath-chair type handle", and four smaller wheels for stability.[2] This arrangement led to it being referred to as the "hen and chickens" cycle, as it resembled a mother hen surrounded by her four chicks. It was trialled by rural postmen in Horsham and, although liked, the design was not widely adopted.[1] There is a replica in the British Postal Museum.[3]

Modern-day interpretation

Modern day pentacycles do not often share the same layout as the original pentacycle, usually using various other wheel configurations.

A 2002 interpretation, specifically designed to use the disused Aérotrain monorail track near Orléans, is more accurately described as a tricycle; although it has five wheels, two are actually used for guidance and are placed on either side of the monorail support.[4]

In 2012 Sajjad Moosa, a Pakistani art graduate, spent almost 150,000 (US$2,100) creating a 48 foot (15 m) long pentacycle using a single front wheel for steering, a middle pair of wheels for drive and another pair at the rear.[5]
