I do not know if this machine is effective against a mounting ... broken. Shake can be a bit much at the handlebar down to the screw which allows height adjustment and folding and the splines of the greenhouse red casing and black moving part.
The casing breaks at the plastic that holds prisoner precisely the head (nut 13 embedded in the plastic ..) with the hexagonal screws. Bilan, change or permanent housing fixing screws not more resin ... Carter = 39 more delivery. So beware !!! I try ... after repair option resin + tapping screws.
