The Reliant Regal is a small three-wheeled car and van that was manufactured from 1952 to 1973 by the Reliant Motor Company in Tamworth, England, replacing the earlier Reliant Regent three-wheeled cyclecar van which had its origins in a design bought by Reliant from the Raleigh Bicycle Company. As a three-wheeled vehicle having a lightweight (under 7 cwt, 355.6 kg) construction, under UK law it is considered a "tricycle" and can be driven on a full (class A) motorcycle licence. In 1962, with the release of the Reliant Regal 3/25, van and estate versions with a side-hinged rear door were marketed as the Reliant Supervan. History Following the launch of the Mk I in 1953, the Regal passed through many revisions in a short period, with the "first generation" using the original wooden frame and discrete-panel bodywork design through to the 1961 Mk VI. The Mk II was introduced in 1954 with a mostly similar design to the Mk1, though it can be distinguished by an updated windshield. The Mk III was introduced in 1956 with a heavily updated design and featured an all-fibreglass body for the first time. This was followed by the Mk IV in 1958, the Mk V in 1959 and the Mk VI in 1960. In 1962, Reliant introduced the Mk VII, code named "TW7" (Three Wheeler 7). This version featured a new OHV Reliant engine (based on a reverse-engineered all-alloy version of the 803cc Standard SC engine used in the discontinued Standard Eight), a new steel chassis and bonded shell design for the body, fully updated visual styling, and was badged based on their number of wheels/bhp. The Regal 3/25, was sold from 1962 to 1968, with a 600cc engine produced 25 bhp (actually 598cc/24 bhp). In 1969, the Regal 3/30 was introduced with a 700cc engine that produced 30 bhp (actually 701cc / 29 bhp). The Regal 21E and Regal 21E 700 were also sold. The 21E version was fitted with 21 extras, which were otherwise available as optional extras to the standard car. These extras included a spot light, a fog light, chrome plated bumper over-riders, sun visors, an oil gauge, outer wheel trims and metallic paint. In 1973, the Regal was replaced by the Reliant Robin (code named "TW8"). Regals MkI–MkII had aluminium bodies and 747-cc side-valve engines. However, during the 1950s, the price of aluminium increased markedly across Europe. In response,
