The Rondo in B flat major was only published two years after Beethoven’s death, in an arrangement by Carl Czerny. It has since been proven that it was originally the final movement of the Piano Concerto no. 2 op. 19, which Beethoven replaced in 1794/95 with the movement we know today. The fact that it closely resembled Mozart’s style might have contributed to this decision. At any rate Beethoven kept the manuscript of the rondo all his life, showing its importance for him. Johannes Umbreit has prepared a new piano reduction that is easier to play and is based on the musical text in the Beethoven Complete Edition.
