Kryptonite Keeper 712 Combo Bike Chain Lock, 4 Feet Long 7mm Steel Chain Heavy Duty Anti-Theft Bicycle Chain Lock, 4-Digit Resettable Combination Lock for E-Bike Scooter Road Mountain Bikes

Heavy duty chain lock and its sturdy. Like the protective cover. Combination numbers easy to set and operate. Probably not the most effective anti theft product on the market but it's a price compromise.

Perfect secure and strong robust chain for locking bike up. It is plenty long enough and being a combination lock then you never have to worry about losing the key.

Really sturdy and heavy lock. The combinations move easily, something which tends to jam on cheaper locks. I feel comfortable leaving my bike locked with this. Resetting the code is also very easy. The lock is very heavy, and adds a fair bit of weight to your bike.

The nut at the end breaks off, making it impossible to use

I’ve been using this bike lock and it’s been exactly what I needed for quick stops and everyday use. It feels sturdy and well-built, not flimsy like some of the cheaper locks you see. The locking mechanism is smooth, easy to use, and doesn’t stick, which makes grabbing my bike fast and hassle-free. What I like most is the peace of mind it gives when I’m running errands or leaving my bike for a short time. It’s strong enough that I feel confident stepping away without constantly worrying about it. The design is also compact enough to carry without it being annoying or bulky. It’s simple, reliable, and does its job without overcomplicating anything. Overall, it’s a solid everyday bike lock that feels like a good balance of security and convenience.

My E-bike is not going anywhere easily against my will with this lock for sure. Its 2KG and tbh yes its heavy but its durable, and worth it.

Rien à dire, c'est un produit de pro

I always had a fear of losing my key or breaking it in the lock like I did once with a cheap lock resulting in me taking a cab back to my place to get my extra key which can and was expensive. Since, I have decided to go with a combo lock. This is a very sturdy lock with the Kryptonite reputation and you can set the combo to something you won’t forget. The only drawback is the weight, but that’s the price for sturdy!

Prodotto di grande qualità, affidabile, ben progettato. L' impostazione del codice personale è semplice e veloce (e l' assenza di chiavi toglie un pensiero dalla testa !!!....) La versione da 90 cm è consigliabile x agganci più comodi a pali o ringhiere. Il peso è importante, ma allo stesso tempo è sinonimo di robustezza e sicurezza.
