So I was wondering if anyone of you lovely folks knew anything about '70s era bicycles, particularly 1.) the Sekai 2500 Grand Touring and 2.) the Peugeot City Express (ladies' version). Specifically, does anyone know what the going price locally is on these models, assuming that they are in pretty good shape? Thanks!

 

I know this guy does.....

 

70's aren't really what folks in the "vintage" bicycle world get excited about, unless they are really top-end models.

Regarding Peugeot;

There were billions and billions of these sent to our shores in the 70's - well, almost. The bad news is that they were never terribly expensive. That's bad because it means that hard core riders didn't take care of them. The good news is that many cycling wanna-bees bought them and never rode them. Nearly mint examples do come up quite a bit. It must be remembered that there were many major races won on Peugeot bicycles. For that reason collectors have interest in them. Others have interest for personal nostalgia reasons.

The top model was the PX- 10. Most have fancy Nervex professional lugs, neat Simplex seatposts, Stronglight cranks, and the horrific plastic-meets-metal Simplex deraillieurs. Earlier models with Peugeot written plainly on the downtube in smaller sizes are probably worth as much as $700 in guideline condition. Later examples or those in larger sizes are probably worth $500 to $600 in guideline condition. Models that do not have the fancy Nervex lugs are worth a few hundred dollars less. Very early PX-10 type bikes which have the Sronglight 63 crank (looks like a 93 but has the logo of a 49D) is very rare and should be worth quite a bit in smaller sizes. There are also Peugeots similar to the one ridden by Bernarnd Thévenet, which has brazed-on brake caliper studs and other trick French parts and is perhaps worth around $ 1,300. Also note that there is some foreign interest in early Peugeot's, so in rare instances much higher values for just the right bike might be possible. Just don't count on it. There are lots of Peugeot bicycles out there, and not many well-heeled buyers looking to spend a whole lot on them.

I think you'll be lucky to get much over $100 for either of them.
