1922 brought the model BB for which Belsize are best known. This had a 9hp 90 degree oil cooled twin giving a top speed of over 40 mph. The company went on to make, in 1924, a 4 cylinder version of similar capacity, and in that same year added two more cylinders to form a unit of 13.4hp, one example of which is believed to have survived.
The firm ceased trading in 1926.
