About the Reliant Regal
The Reliant Regal 3/25 was a significant evolution of the three-wheeled concept, introducing a glass-reinforced plastic (GRP) unit construction body and a lightweight overhead-valve aluminium engine. Designed to be driven on a motorcycle licence in the UK, it offered affordable weather protection and seating for four. The 3/25 designation refers to its three wheels and 25 brake horsepower. While often the subject of British comedy, the Regal was a genuine commercial success and remains a cult classic for its unique engineering and charm.

Reliant Regal fun facts
- The Regal 3/25 was the first Reliant to use a unit-construction GRP body, rather than a body-on-frame design.
- Because it had only three wheels and weighed less than 8 cwt (406 kg) dry, it was legally classified as a tricycle, qualifying for lower road tax.
- The 701cc engine was Britain's first mass-produced lightweight aluminium engine, weighing only 19 kg when bare.
