The problem is that it is a little too small for my taste (I'm 1m77) and suddenly I have to adjust my chair lower than normal and therefore have the legs a tad too bent and back gotta put some of his own too. (Oh and there are no brakes to the wheels: s a pity) I received it with a crack on the white board on the lower left side roof (so visible, but poses no problems other aesthetic) .
Most will agree to a young 10 to 16 years or until 1m65 / 70.
Otherwise the plan for installation is fairly well detailed, although a bit small for some parts with reliefs require a few seconds of attention to distinguish and understand that they must have available the assembly.
