Are these locks any good to use?

Yes very secure and easy to maneuver

does this contain lead?

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.

Does this fit the super 73 ebikes??

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!
