’80 Motobecane Sebring
1980 Motobecane Solex
ID has 4 stamps:
12__79__50V__B
(Dec ’79 25mph)
1980 Family Photo: Above are all of the 1980 Motobecane USA models and colors, from the sales brochure. The Sebring is made in Italy and is covered in a separate section, under Italy-made/MB Sebring. The Solex is made in France but covered in a separate section, under France-made/Solex.
Center Stands: Notice how the center stands on the Moby and Traveler are more vertical than most Motobecane center stands. That is because these photos are of brand new bikes. The center stands become angled more forward with age or heavy use.
Speed Version is on ID plate: On the frame behind the headlight is the ID plate. The lower squares say model (left) and speed version (right), stamped in. Before 1980, A=30, B=25, C=20. From 1980 on, A=20, B=25, C=30. Before 1978, no letter, just 20, 25, or 30 (mph). Hope yours is a 30! 1980 was the last year for US models. 1981 had new 17 digit VIN and new EPA and DOT noise and safety regulations. That was “the last straw”.
Pulley clutch types:
left, variator
right, non-variator
Pulley-Clutch Versions: There are two types of pulley-clutches, variator and non-variator (Dimoby). They look almost the same. The crankshaft is the same for both. The variator type pulley clutch sticks out 5/8 inch more than the non-variator type. The variator type front pulley changes size, from 10 to 20 mph, as the bike speed increases. So it is like a two-speed, with a low gear and a high gear. The non-variator front pulley does not change size, but is solid and fixed. So it’s like a one-speed.
To see this on a bike, you have to view the belt where it goes around the front pulley. There are usually covers or belt guards in the way, blocking the view. Another way to tell the difference is by the clutch nut and outer clutch wheel. The variator clutch nut is very deep, while the non-variator one is shallow.
