Review: 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.

## Questions & Answers

**Q: Are these locks any good to use?**
A: Yes very secure and easy to maneuver

**Q: does this contain lead?**
A: I am guessing this question is in reference to the California's Proposition 65 warning on this product. That warming can be found on seemingly countless products. Proposition 65 is so overly broad that the warning can be found on practically everything, including organic salad dressings.

The bike lock probably does technically contain an amount of lead greater than zero. Whatever amount of lead found in this bike lock should probably not concern you too much though (or concern you at all).

Lead is a major problem, but it’s not the likely-minuscular amount in a random bike lock that you need to worry about. It’s the high levels of lead in the air we breath and lead in the water we drink that’s the problem. It’s the lead pipes that are connected to our houses that’s the problem.

**Q: Hola buenos dias el candado viene con el cable la guaya**
A: No solo el candado viene

**Q: Does this fit the super 73 ebikes??**
A: If your bike cost more than $300 I just wouldn’t buy this one. I’d recommend getting either the orange or the yellow Kyrpotonite locks OR getting mini u-lock to accompany any ulock you get. 

I had just this one and it got stolen. Best of luck!

*by Á***G on 13 June 2025*

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.
