The Bedford WHB and Bedford WLB were chassis for buses made by the British truck manufacturer Bedford. These were the first chassis for buses which Bedford produced.
The chassis were based on the lightweight Bedford WLG 2-tonne lorry chassi produced since 1929. This truck was based on a design by Chevrolet. The WHB had a wheelbase of 131 inches (3.33 m), while the WLB had a wheelbase of 157 inches (3.99 m). The second letter in the model designation referred to short (H) or long (L). wheelbases.
The vehicles were fitted with a six-cylinder petrol engine with a displacement of 3.18 litres. The engine developed 47 kW at 2800 rpm. It was rated by 27 taxable horsepower. They were fitted with an unsynchronized four-speed gearbox. The electrical system had a voltage of 24 V.
The bodies were usually made by Duple. Other body manufacturers were Waveney, Grose, Rainforth and Plaxton. The bodies for the WHB had 14 seats, 20 seats for the WLB.
The production of the chassis began in 1931 at the Vauxhall plant in Luton. As the demand was low, the production of WHB was discontinued in 1933 after 102 buses were made. 1892 WLBs were built, with production ending in 1935.
