Not super easy to assemble but I got through it in 1 hour far from being insurmountable, lightweight, very good, we feel that it's tough! On the practical side, it is easily stored because it folds, easy to assemble, 2/3 strokes of keys and voila, in 5 minutes it is mounted with 1 bike over. When we want to put 2 is a bit longer because it takes a few minutes to make a tetris (limited space). This flip-flop and it's great to open the safe. For the price: great product, to recommend without hesitation, for on being able to find better !!
