here is my mystery bike! it is a foldable Spalding made by EBE industries .co but I have no idea how old it is or if it is some sort of prototype. I tried to look up the many numbers on this bike but have had no luck, that is why I have come the experts
so this bike is mainly fitted out in shimano components such as: Shimano high power lever brake levers, shimano cables that have shimano 1480 printed on them, shimano inter-M rear drum brake and a shimano SG-3R35 three speed hub. the bike used to have presta valves but they were smashed so I replaced them with shraeder valves. it also has nitto bars, goose neck and seat post. there is no name on the 3-piece crank. the fork has a weird bracket that has the words K.B.F. and under it has PAT.P (I assume this means patent pending).

so could you guys tell me all you might know, thanks!
