The '''Velo-Klapp''' is a strut-folding 9x12 plate camera with a focal-plane shutter, made by [[Ernemann]]. The name of the camera probably refers to it's  compactness when folded, making it suitable to be taken on bicycle trips. The focal plane shutter makes the Velo-Klapp slightly bulkier and heavier than the [[Velocam]], however, which has only a three-speed front shutter. The Velo-Klapp's shutter gives speeds up to 1/2500 second.<ref name=Cat>Catalogue [http://www.cineressources.net/consultationPdf/web/o000/256.pdf ''Ernemann Cameras sind die Besten; Anleitung; Liste No. 91''], p.14. The catalogue is undated, but describes the Bob III (1924-26) as new; at [http://www.cineressources.net/recherche_t.php Ciné-Ressources]. The Velo-Klapp and Velocam are shown on facing pages, and the Velocam is specifically described as for alpinists, cyclists and tourists.</ref> It was available with any of several lenses: Ernemann's own f/6.8 [[Rapid Rectilinear|Detectiv-Aplanat]], or f/6.8 or f/5.5 Doppel-anastigmats, an f/6.8 [[Goerz]] Doppel-anastigmat Syntor, or an f/6 [[Rodenstock]] Imagonal.<ref name=Cat/>

The camera was available with a plate-changing magazine, for twelve 9x12 plates or twenty-four sheets of film in sheaths, a roll-film back, or a film-pack adapter.<ref name=Cat/>
