I can't tell specifically what model, if that's what you want. They appear to be early 70s road bikes, the kind that Japan glutted the market with back then. Most had hi-ten (1010 steel, I believe) frames. Standard gearing was 42/52 and a 14-28 5-speed freewheel. The suicide brake levers and stem shifters mark them as low-end examples of the genre. In fact, the sloppy brake and derailleur cable routing on the men's model would've lead me to believe it's a dept store bike, if it hadn't been for the 3-piece crank.
What I CAN see:
*Chromed steel spoke guard
All tipoffs that they are low-end bikes
The mixte framed bike seems to have a bent fork
sidepull brakes - might mark it as closer to '75 vintage?
1953 Schwinn Debutante, 1971 Hercules 3-speed, 1973 Schwinn Suburban, 1990 Huffy White River, 1990-something Bianchi Advantage, 1996 Trek 800
Yeah, the pink bike looks a LOT like my 1973 Schwinn Suburban, only with drops rather than touring bars.
Schwinn used the same frames for a range of bikes, and just had fancier components and accessories on the higher-end versions. Continental was a little fancier than Varsity. I'm not sure where Suburban came in, but it's the same frame. They used them for ages, too. I think the last ones made in Chicago were in 1982.
I have one that looks like that mens bike on top.I still don't know what brand it is.mine just says A-PRO on the neck and lower tube.
just got a new freewheel for it yeasterday.now I need tires tubes and cables.oh and a seat tube.
Like they said,steel chrome wheels,steel frame.(should never worry about bending frame or wheels.)3 pc crank.
hope it rides better than the beast I currently ride.(wally world special)
