This is a Ostrad (frame number 2001).
Did you ever dreamed of going with a recumbent? Did you saw something like this on the road? Other people curse the folks who go so comfortable through the daily traffic jam. But I don't want to speak about people in stinking tins.
Ostrad is a bike shop in the centre of Berlin, in the "Prenzlauer Berg". The people are specialized on recumbents and touring bikes. It's a member of the VSF, Verbund selbstverwalteter Fahrradläden (Association of selfmanaged bikeshops) like the shop, where i bought my recumbent, the Fahrradies (paradies for bicycles) in Halle. You can find shops of this union in whole Germany and they can order most of the recumbents which you can buy in Germany and sometimes outside. Good service and advises are inclusive.
But now to the bike itself.
The AMP fork should be known only by older mountain bikers. It's designed according to the parallelogram principle and it's so from the point of view of design the best what you can buy. Like all hydraulics the seals of the damper are a problem - my are relative tight since I bought the bike. The fork was shorted to fit 20"-wheels.
The back suspension wing is a development of Ostrad. The suspension comes from a big elastomer. This is based on a wing of the frame and is guided by a axle. The axle can rotate around one axis parallel to the axis of suspension wing - nonfixed triangle. The axle of the suspension wing is beared by a wheel suspension from Trabant, the famous old east german car. You shouldn't have problems with this parts.
On the same axle rotates a sprocket cassette body from WECO. It has a app. 2 cm wide needle bearing. A rear derailleur changes the five sprockets on this cassette. From a sixth sprocket goes the second chain to the rear hub. Only rear derailleurs are in use and the front derailleur, or should I say chain snatcher, can be still in the shop.
All wires are inside of the frame and have two veins. With this construction you can connect the white front and the red rear light directly with current and ground.
