ClassOpen single-seat cargo tricycle
Built1,000 units
ADI's main post-war urban delivery vehicle. The engine and chain drive sat over the single front wheel, while freight rode on a rear platform or enclosed box. Berlin postal authorities tested it without placing a fleet order; the 1,000 figure is a production milestone, not a final total.

How this is measured → This record contains useful sourced evidence, but it does not yet meet the reference-ready standard. Still needed: attributed imagery. Fields we cannot source stay empty rather than guessed.
Research notes
At least 1,000 had been produced by 1951; final total through 1956 is unknown.
