In the interwar period, there were a total of about 20 manufacturers of motorbikes, mopeds and outboard motors in Poland. In addition to the famous Sokołów, which is still common today, motorbikes of lesser-known brands were also produced, which are now coveted and highly valued by collectors, such as MOJ, Perkun, Podkowa, Niemen, Wul-Gum, Lech, Tornedo, SM , or Zuch. Motorbikes, their manufacturers and people involved in the production of Polish two-wheelers can be found by the reader in this book. In its third edition 30 new, unique photographs (including Lech, Lot, Wul-Gum I motorbikes.) ) have been placed. The whole is a treasure of knowledge about Polish construction and production achievements in the field of two-wheelers during the Second Polish Republic.
