Known as the slogger the M21 was popular as a sidecar combination and came equipped with twin crable integral sidecar lugs

 

In the TV Comedy Sitcom, On The Buses the hapless Arthur and Olive have a 1930's BSA M21 Combination

 

The BSA M20 and M21 were the mainstay of the AA breakdown fleet in the 1950's and early 60's, the AA used over 2000 with their last purchase being an M21 of 1961.

The M21 combination proved rugged and reliable, powered by an unsophisticated 600cc single cylinder side valve engine with a modest 15bhp mated to a four speed gearbox and a top speed of around 50mph.

The AA fleet differed a little from the standard road version of the M21, specified with a stronger front brake, a 12 volt alternator instead of a dynamo, to power the two way radio and higher handle bars. Various types of sidecar, leg gaurds and fairing were used.
