Motobecane
 

Hello,

I have a Motobecane silver female bike I purchased in the '70s, which I've ridden only a handful of times, so it's in great condition with all its original parts.

Here are numbers I found on the bike:
On the seattube -- 1020
In two separate lines on the bottom bracket -- 38?2557 and ?04 (? = indiscernable)

How/where can I get more information on its model, history and worth?

Thanks!

You can get a lot of info right here.

Post some good clear pics of the bike from the drive side. Include some clear pics of the components.
