Le seul bémols est l’attache au cadre en plastique qui a déjà lâché un coup lors d’une sortie. Mais cela a été remplacé gratuitement.

It was Nice while it lasted. After a month, the lock mechanism kept getting jammed. I returned it

Das Schloss ist einfach Mega, etwas schwer aber es funktioniert alles und es ist sehr robust. Selbst an kalten Tagen hat alles funktioniert und das Schloss ist nicht eingefroren. Die Halterung für das Fahrrad ist dabei ich habe sie aber nicht genutzt nach über einem Jahr sehr zufrieden

Veo las muescas de que lo han intentado romper varias veces, pero no lo han conseguido. Mi bicicleta duerme en la calle y tras un año en la calle se ha oxidado, cierra peor pero sigue funcionando.

product works well and looks of good quality. however, received it damaged as seen in the photos. the logo was rubbing off and theres a chip in the black paint on the shackle. packaging was not damaged so not sure what happened to it. too troublesome to return, having to wait for a new one so wont be returning
