I have a Citizen Gotham 7 that folds quite quickly (easily in 10 seconds). On mine the wheels lock together with a ball catch when folded and the frame stand supports the crank so that the seat post doesn’t need to be used to balance (such as the case with a Dahon). For some reason your frame stand isn’t pointed down. The bike can also easily be rolled when folded (sometime I assume the Alhambra does too but you don’t show it). Disadvantages are that both the derailleur and the handlebar & brake levers are on the outside when folded so can easily be damaged if not careful. Also, stock gearing is very low.
