Unfortunately, the seat unit is not hinged. This is the biggest drawback. I bought it for the holidays and want to take it on the plane, but unfortunately we then 2 parts. The frame folds super small, but you then still hold the rigid seat unit. Otherwise, the Zapp Xtra is super. Stylish design, it can be really easy to drive, ideal for the city by bus and train and stairs. The Shopping Network is also okay and sufficient for small objects from. It is great that the child can go by and against the Fahrtichtung, which is very rare and that's why I bought him. The sun visor is very large and the seat easily adjustable. A really chic city car
