The Bartel BM 6 was a Polish biplane trainer fighter aircraft of 1930.

The aircraft was designed by Ryszard Bartel in the Samolot factory in Poznań, as a trainer-fighter plane.

A distinguishing feature of all Bartels was an upper wing of a shorter span, because lower and upper wing halves were interchangeable (i.e. the lower wingspan included the fuselage width).

The second prototype BM 6b, with a Wright Whirlwind 220 hp radial engine, was ordered, but work upon it ceased with closure of the Samolot factory in mid-1930.

Rectangular two-spar wings with rounded ends, plywood and canvas covered.
