I just bought this bike for $20. Its in great condition. Seems like a nice bike, very unique. The frame is 4130 double butted Chro-mo. It has Siguno Cycloid chainrings which are oblong shaped, siguno vp cranks, deore (no markings like xt or lx) derailuers and shifters, shimano cantilever brakes. It has a sticker on it that says "Tange mtn bike". Either the frame or the whole bike was made in taiwan. Its rear brakes are mounted under the lower bar that connects to the rear dropouts. There is a space for 3 spare spokes on that same bar, as you can see in the pics.

Does anyone know any info about this bike like years produced, original price, what it could be worth now, what kind of riding it was made for, ect.

I did some research, and all I could find on the bike was that the siguno cycloid chainrings were made durring the eighties.

Thanks in advance
