Semi-mixte - does it have a "name"?

On vacation last week and saw this bike in a shop window as display art....not really interested in identifying the bike itself but the frame style was unusual....mixte to the seat tube then regular seat stays.....is there a name for this style of frame? Was it ever any good/popular?

Thanks for making this query.

Between the seat tube and head it is like a berceau.

What is the nature of the plugs in the laterals?

Have seen some where the plugs are white nylon and others where they chrome plated.

Do not know answer to question; shall look forward to reading the messages of the experts...

A lot of people call them just a "step-through".

One would expect there must be a specific name for this type with twin laterals.

Excellent framing of the woman's head inside the wheel, BTW.

Given the shortened berceau stays, I propose calling it “berc”.

French Army Bikes -Mixte

Back in the 70's I'd heard from a very reliable source that mixte frames were designed for the French army: one size fits all and they could carry a lot of hardware. Made sense to me.



[MENTION=319010]Narhay[/MENTION] "Col de cygne means swan's collar" A better translation is Swan's Neck because of the gracile form of the drop tubes. Much more romantic term than Goose Neck used to describe stems on US bikes BITD.



In the 70's we carried Gitane and Bertin mixtes at our shop. Gitanes came in 50cm, 54cm and 57cm, Bertins in 52cm and 56cm.

This 1980 flyer shows a Bertin berceau 3 speed and info on 3 models of mixtes.

Most of the French drop frame bikes were considered to be women's "Cycle de Ville" bikes for around town use.



Our shop was about 3-4 blocks from the University of New Mexico. We had a difficult time selling mixtes to petite young women who didn't want a "GIRLS BIKE".

Most of our mixte customers were were older gentlemen who had problems swinging their leg over the top tube of a diamond frame bike and more mature women some of whom were serious riders and wanted a bike to commute on while wearing a skirt.

We had Bertin build son 48cm frames for us. They were made for sewups or clinchers with 700x20c tires. We assembled them to the customer's wishes and budget. Most small frames rode and handled like wheelbarrows! These performed like larger frames.

I don't believe that this is a jumele style frame but rather a drewed berceau style frame. If you enlarge the picture and extend the mid-stays to where they would mate with the seat stays, there appears to be a small remnant of the mid-stays attached to the seat stays. Attaching the mid-stays at this higher point eliminates the need for the more complicated s-bend used on many mixte drive side mid-stays to provide chain clearance.
