Could someone help me recognizing what bike is it? I would love to restore it, but then I have to know which details are originals and which not. In front it has emblem with lion (smth like Peugeot cars) and above written "SISU". It could be from Sweden or Finland (SISU in Finnish means "have guts"). Also I found that the bike originally has been orange (visible inside the frame). It has Nokian front tyre, which could be original and road-bike type steering wheel. I have suspicion that at some point of time it was with more than one gear (the hub may have been changed).
