to fold the stroller yo need to:
1.fold the hood back up against the handle.
2.release the locking clamps at either side of the stroller.
3.simultaneously lift the secondary safety catch and swing the handle forward.
4.holding the frame at the rear, press down on the rear basket tube.
5.you also can lock the frame with the strap next to the frame.
