The closest match I can find to this example (steel forks and rear triangle, aluminum ovalized main frame, M bars, front fold to non-drive side) is a bike marketed as the Groo M3.
Other folding bikes built on the basic Andrew Ritchie folding design with varying differences are the 3sixty Sigma, B-Bike, Backer, Burke, Camp Royal, Chedech, Cigna, Crosshead, Curl, Element Pikes, Flamingo, Flova, Iruka, Java, Jcat, Kreuz, la Bike, MIT, Neo, Pico, Sanye, South Point, United Trifold, Viking and Week Eight.
