A pentacycle ("hen and chickens" ) is a human-powered five-wheeled vehicle.

Origin

The original pentacycle was designed and patented by the architect Edward Burstow in 1882.{{cite magazine |title=Transport at Horsham and in Sussex: From 1550 to the Present Day |url=https://books.google.com/books?id=Q1pNAQAAIAAJ |access-date=23 February 2016 |volume=12 |year=1938 |publisher=T.R.

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. There is a replica in the British Postal Museum.{{cite web |url=http://www.postalheritage.org.uk/collections/getrecord/GB813_OB1995_357 |title=Replica pentacycle |publisher=British Postal Museum |access-date=3 December 2015}}

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.{{cite web |url=http://www.vvork.com/?p=6083 |title=VWORK |access-date=12 October 2012}}{{Better source needed|date=February 2016}}

In 2012 Sajjad Moosa, a Pakistani art graduate, spent almost {{INRConvert|150|k}} creating a {{Convert|48|foot|m}} long pentacycle using a single front wheel for steering, a middle pair of wheels for drive and another pair at the rear.{{Cite web|url=http://nation.com.pk/islamabad/10-Apr-2015/48-feet-pentacycle-of-peace|title = 48-feet pentacycle of peace|date = 10 April 2015}}
