The Bond Minicar Mark B was introduced in 1951 as the successor to the original Mark A model. It retained the fundamental principles of the earlier design—lightweight construction, three-wheeled layout, and affordability—but featured a number of mechanical and cosmetic improvements aimed at enhancing usability and comfort.

Powered by a 197cc Villiers two-stroke engine, the Mark B offered more performance than its predecessor, allowing for slightly higher top speeds and better hill-climbing ability. The engine was still mounted in the front and directly powered the front wheel, which also handled the steering. A new three-speed gearbox with reverse was introduced in this model, making it more practical for everyday driving.

The Mark B featured an improved tubular steel chassis and slightly more robust suspension to better handle road conditions. Its bodywork was refined with more sculpted lines and a better-fitting roof, along with a more enclosed cabin to offer increased protection from the elements. Despite these upgrades, it remained extremely lightweight and economical to run.

The Bond Minicar Mark B was an important step in the evolution of British microcars. While still very basic by modern standards, it represented a move toward greater refinement and practicality in the ultra-compact vehicle category. Today, it’s valued by enthusiasts for its historical relevance, simplicity, and its role in providing accessible personal transport in postwar Britain.
