Mini Mystery Muscle Bike

[Bike from the Dead]

Honestly saying - not really. My advice is try to google it in German. I did search for some info on it briefly, but could not find much more info either.
The reason for different seat stays is probably, as i mentioned before, that yours is slightly earlier then the one on the picture.

Alright, I'll try that. Thanks!

Behold, the elusive goose neck stem!

I take it that's a rare piece?

The BB is the bottom bracket. It is the bearings that help the crank turn.

Oh, ok. I'm not familiar with all the abbreviations of bicycle anatomy yet.

I don't know if it is. Bikes from the 20s and 30s had them a lot and I had one as a kid on my tricycle.

A good quality gooseneck stem could be a sought after piece, especially if the retro racers recognize the brand. If you were to do a retro mountain bike with drop bars, that would work perfectly. Sometimes referred to as LD, or "limp Richard" stem.

:S

The cranks look like a German "Glockenlager". There really isn't a way to use a regular crank puller on them. They are a pain to work with! Best German board I have found is:

Google translate will get you close, and some people are willing to answer a question in English. DeepL is a much better machine translator.

Ok, thanks! I'll take a look at it.

Ok, cool. Yeeeeeeeaaah, I'm just going to stick with "gooseneck."

Same.

Here is a bike that has a gooseneck clamp with a normal stem. Those bars are not going to twist.

How do those cranks work? How are they put together?

 

[pebblewurm]

Just google "glockenlager" for a lot of information. Basically, they are steel cranks that are pressed onto a square taper axle. BUT and a big BUT, they are not threaded for a conventional crank puller. There is a youtube video that says to remove them, you need a brave man and a big hammer. If that doesn't work, get a braver man and a bigger hammer. There is a tool that clamps into the crankarm with a threaded hole for a bolt to force them off the axle. It is a weird system, but was used for decades.

Jeez, so what you're saying is that should I try to make this bike rideable again, I'm going to have a hard time pulling out the crank to fix the bearings?

Would you happen to have a link to that video? I'd like to see it.

Here's one video- not quite as I remembered it:

They are not impossible to take apart. Just consider it a challenge!

 

[deorman]

If you manage to take apart the side that does NOT have a sprocket, the other side will not need to be taken apart.
