Best go to France. And look here to find something: https://www.leboncoin.fr/recherche/?text=Motobecane
What do you actually want to know about these models?

Are there any information about how many of These types where built/sold? Are the MBK-models better or less better than the Motobecane-models?

Sorry, found this topic too late. And most of my questions are short questions...

What about and where to get the last Mobylette versions like 51, 88 or 881? How is the situation on the market? And "No", i don't mean the Collection series ;-)

Thanks!
51 is never delivered in The Netherlands I think, only the 40, 50 etc.
In Belgium (www.2dehands.be) you find more of them.
88 is also a kind of rare model in The Netherlands. You find them more in Belgium and especially France.
881 I never heard of. But I looked at Google pictures and also looks like a Belgium and France model.

You're looking for a heavier model? I think you have to look for it in Belgium and France. The change to find it in The Netherlands is smaller, because they aren't deliver here so much as in other countries (with mountains... ;) )

MBK is a later production. They have some benefits about electrical ignition, membrane, .. and stuff
But they have less old-fashion look ;)

The 881 is the last model of the AV88. the 1 in 881 refers to the fact, that it was equipped with the AV10 engine, the same engine you find on the 41 and 51 models and some pre- Yamaha models (pre 1984). These were made upto 2002. While they were offered as 881, you could also still get them as 88, with an AV7 engine.

The difference between AV7 and AV10 is the amout of ports, better bearings and better crankshift?

The most important difference is the intake position, which is not on the cylinder, but on the crankcase, through membrane. This system eliminates, largely, the blowback of, alreadysucked in,fuel/air mix, when the cylinder travels down. Resulting in more mix in the cylinder per powerstroke. Especially at low revolutions, where the amount of blown back mix is larger. The standard Motobécane AV10 setup also has one extra port, at the back of the cylinder (as opposed to the two in the side with an AV7 engine, improving the flushing of exhaust gasses.

I know these differences from Vespa scooters. Owned them for over 30 years. But I never knew, that the system with membranes was standard in late Mobylette models. It is often use with resonance exhausts. Are such things available for a Mobylette?

Your are really helpful, Joost. I worked on Vespa 2-strokers, but know my demand for speed is not needed anymore. So why not try Motobecane? I found my first EEG at a friend near the border to The Netherlands. Later,I got to know Haagsehans (never seen him in person...). And that's my little story why beeing here :)

The fact, that Motobécane introduced chrome lined cylinders on their mopeds in the early 50's, gives an idea, that, somewhere in the organisation, people were really interrested in new technologie. Couple that with Jean Bidalot having started his career at Motobécane and being responsible for the racing segment of the brand and the development of the AV10 is not such a big surprise. Again, Motobécane introduced technology, quickly followed by brands, wanting to build performance mopeds. An AV10 engine could look like this (it still has to prove itself, but looks impressive): Afbeelding

Hoe zet ik de twee remschoenen met die twee veertjes weer op de ankerplaat?
Ze vliegen telkens over de werkbank.

Hallo Hans,
1. bevestig de 2 veertjes aan beide remschoenen.
2. schuif de remschoenen met de platte kanten gedeeltelijk op de vlakke draaihevel.
3. bevestig de linkse remschoen op de ronde as en houdt de rechter een beetje schuin (veertjes moeten blijven zitten)
4. Duw de andere kant schuin over de borst heen. Met wat wrikken en hefboomwerking klikt hij op zijn plaats.

Als je het ziet denk je: "Is dit alles?"
Ik zal in HHW een demo geven en als ik tijd heb maak ik wel een korte video.

Inderdaad mijn werkhandschoen zal er tussen die kon ik weggooien.
Dus met een variant op de hefboomwerking van Henk als volgt gehandeld.
Ankerplaat in de bankschroef (doekje er in tegen beschadigingen).
De remschoenen met de veertjes vast boven op de nokken gelegd en die open geknepen met een (fiets) vorkspreider.
De remschoenen stonden ver genoeg open en onder spanning om over de nokken de laten zakken. Bingo.
Dat ligt alvast klaar voor montage.

Got someone further information about the Kaptein S46B? Perhaps pictures? I was offered one, but cannot recognize it as a Kaptein. What are the differences to a AV89? Since what year was ist build?

Thanks!
Thomas

The S46B is the MobyClub. There are several versions since 1961 (or thereabouts), to 1968, when the model was cancelled and replaced by the AV89. Mine is from 1967 and is an AV89, with 19" wheels, instead of the standard 18"on standard, French AV89.
This is mine:

This is the one I was offered. Was the later AV89 sold as a Kaptein or a Motobecane?

It was sold as a Kaptein in Holland (and maybe Belgium). But this is an AV85.

Could you pls explain the differences? An AV85 has the AV7 engine instead of a AV10?

What type of Kaptein is this? An early AV50? Is it hard to find the right grapped rubber, the rear light and a stand?

Yes, it's a AV 50. Very easy to get parts for this one.
