Bielecki is married and with two children. The former prime minister is well known for his adoration of motorcycles. In September 2012, tabloid newspaper "Fakt" photographed Bielecki arriving and leaving work at the Chancellery on a BMW F800R, dressed in jeans, a black jacket, sneakers and wearing a backpack. The tabloid noted that while Bielecki's position in the Chancellery was entitled to a free limousine for commuting to and from work, the former prime minister preferred instead to use his personal motorcycle.
