Rog Sport? Anyone know anything about them?

I've been watching Craigslist for an old folder to fix up for my wife. This bike, a Rog Sport (made in Ljubljana?), pops up, which is something I've never heard of, but it's got a standard, older folder look, and it's priced at $15, so there's not much to lose. I'm just wondering what experience anyone has (if any) with this model bike or something similar. It appears to ride okay, but I think the bottom bracket might needs some work. 3-speed hub/coaster brake shifts fine, but it doesn't stop great. The hub is not Sturmey-Archer. I think it's Shimano. Did they make a 3 speed hub? It shifts from the non-drive side, which is different from any IGHs I've seen. Or at least I've never noticed any that have shifters hooked up on that side.

Here's the pics:

Rog was a state owned Yugoslavian company that started making bicycles in the early 50's. They were based in Ljubljana, now the capital of Slovenia. These "U-frame" folding bikes were made starting in the 70's and were exported to many countries including the U.S. They were a fairly cheap bike and were made in the thousands and don't have much value as a collectible but for $15 you certainly don't have anything to lose. I think they were made until the early 80's, someone sent me a photo (below) of a late model.

Good to know. I actually felt bad about giving the guy only $15.00. I figure any bike that's in ridable condition is worth at least $50, let along that it was a folder, and seems to have been around a while and held up pretty well, except for the rust.

Once I saw it, I had to ask again, "How much are you asking?" Just to make sure he didn't feel like he was getting ripped off. He said, "I'm asking $15, but I got this other bike frame and a couple of other parts I need to get rid of. If you can make all of that stuff disappear, I'll give it all to you $10."

So, yeah, assuming I can clean it up and fix it up, I think it's money well spent. I just need to convince my wife of that... Or hide it from her until it's done. Good thing it's little. I just need to find a home for the other, full-size bike frame that came with it.

Rog in Ljubljana, Slovenia; Partizan in Subotica, Serbia and Unis (former Pretis) in Sarajevo, Bosnia and Hercegovina were the three bicycle producers on former Yugoslavia. The bike in these potos is Rog Pony, (also produced with other names by the other yugoslavian manufacturers) is one of the most popular bicycle in former Yugoslavia. It's a derivation of a folding bike made in Italy, I'm not sure of the brand and the model. Probably Rog started to produce the Pony in the middle or at the end of 1960-s, with integrated rear rack, welded to the frame. The Italian producer reacted, and soon Rog (and the other yugoslavian bike producers) made a simple modification, they made the frame without the integrated rack, and produced separate screw mounted rear rack. Most of the bikes came with front steel caliper brake and rear coaster brake hub: on some models, I think the older ones it was the Sachs Torppedo Jet or similar screw clutch Sachs Torpedo; most of the later models have czech-made Favorit (nowadays Velosteel) coaster brake hub. I've seen only few bikes with a rear freewheel and two caliper brakes. The quality of the hubs was exellent, the rear ones and i think the fornt ones also were forged. I don't know if this particular bike is an export model with internal gear hub. The bottom bracket is Thompson style with pressed cups, with almost excellent qualitiy; on every bike I've seen the right crank is pemanently forged to the bottom bracket spindle, and the left crank is cottered. The cone on the left side is with left-hand thread. There's a cheap modification if you want to put cartridge bottom bracket: Take an old cheap frame with a british (ISO) bottob bracket threading, cut only the bottom bracket shell, it should fit snugly in the empty bottom bracket of the Pony (or any other Yugoslavian built bike with Thompson style bottom bracket). Previously drill a hole in the bottom part of the shell on the bike, and weld through that hole, to fix the new shell in place. I think it requires very good centering and welding skill, and probably some facing of the bottom bracket shell, but, you get the idea.
The wheels are of good quality, especially the hubs, but the rims are steel, not to good for today's standards. I think that they are built with 28 spokes.
There were also non-foldable versions, and also a non foldable verision with 24 inch (507 mm) wheels.
Even thou it is a folding bike, almost no one in Yugoslavia used these bikes as folding bikes, they were used as children's bikes, lady's bikes, and commuters, (and a predecessor of the BMX and MTB) and were very popular, something like (but not nearly as) the Raleigh Twenty. Along with the coaster brake roadsters produced by the three bike producers in Yugoslavia, Rog, Partizan and Unis, these were the most popular commuter bikes in Yugoslavia. At the end of the 1990-s and, I think at the beginning of the 2000-s, Rog started to put aluminium rims and ISO bottom bracket on their bikes. Now, I think that the Slovenian producer oh household apppliances, bought the trademark Pony, and started to produce a new version. Here's their website https://rogbikes.com/?lang=en
All in all, it's a nice bike, whether you plan to run the original parts, or use it as a project for upgrading. I'll keep it if I you ask me. We have nice memories with this kind of bikes, and I kind of like them.
