Please identify, Lago bike from Germany
The last image says

Moped-Fahrrad (Moped Bike)
Mähmaschinen (Lawnmowers)
OTTO D... (A name obv.)
Reperatur...Werkstatt. (Repairshop prob.)
Friedrichs.....en? (Riedrichshafen? Reflection in the way)

That would be a sticker from a repair / service shop for mopeds, bikes and lawnmowers
The second to last should be the brand, as there is another bike from &quot;Liebigt&quot; for sale here: http://www.dealmywheel.de/neue-gebrauchte-fahrraeder/muenchen/741027/frisch-restauriertes-sammlerstueck.php
I can find a few second-hand Liebigt frames on ebay and other German thrift sites, but I'm unable to find any wikipedia article or related information on that name, so other then confirming, that &quot;Liebigt&quot; is indeed the vendor, I can't provide any information on the model other then it should be from around the 1970s or earlier.
