Kryptonite Keeper 785 Bike Chain Lock, 2.8 Feet Long Heavy Duty Anti-Theft Bicycle Chain Lock with Keys for Bike, Motorcycle, Scooter, Bicycle, Door, Gate, Fence

Best lock I’ve ever had 👍👍🚴

Good and strong very easy to use

I have every confidence in this lock. I would imagine there aren't many people around regular walks of life who could breach this lock. Its exactly what I was expecting.

This lock is very reliable can’t go anywhere with my bike without it

A sturdy chain lock. Just fit my child’s bike.

It's pretty good, does the job and there are no mechanical problems, no rusting and no seizing up so far.

Good lock, but not quick - getting the key in correctly isn’t always simple - especially when it is around something and you can’t see the keyhole. But you do feel it is secure.

Solid and chunky, good for this price point. Have been using for 3 months with no issues. However just recently I've noticed the lock becoming reluctant to open. I've applied grease to the mechanism which seems to help a little, but probably 3 in 10 times, the lock will rotate but not disengage, requiring considerable force and several attempts to get it to open. Less than ideal when fumbling around in the dark on a rainy morning.

Very good!

Great quality lock. Would definitely buy again

重くて強い感じが良いですね。 ロックは軽い＝弱いので重いのは仕方がありません。 でも重くても弱い物もあるなか、クリプトナイトはとても信用ができるので満足しています。 ロードバイクでもクリプトナイトのU字ロックを使っています。 鍵の開け方はクリプトナイト共通みたいですね。途中で回してしまうとクルクルと空回りするので、ズレてしまったら回しながら押し込むと嵌るという感じが同じでした。 それと鍵はロック状態にしないと抜けないのも一緒。チェーンロックとしては、外した状態で鍵が抜けると満足度がかなり上がると思います。 長さは丁度良いと言えば丁度良いし、あと10㎝くらい短い方が良いような気もするけど、まあ、これで良いかという感じです。半端ではあるけど長すぎることはないのでとりあえず満足です。 若干使い勝手は悪いところはありますが、慣れれば大丈夫程度の物なので、お勧めできるロックだと思います。

Easy to lock and sturdy chain

My experience: I recently got a new electric scooter, and decided to get a lock with it to replace my old U-Lock from Masterlock. I must say that this Kryptonite chain lock is insanely well-built! I am not a fanatic in locks, but I can definitely tell that this is a great quality lock, and I have had no issues with being able to lock my scooter anywhere with it. Pros: The lock is very versatile. The chain design makes it extremely easy to lock and ensures that thieves have trouble cutting it open, especially if you make well-designed loops around areas around the scooter that are very hard to physically access hands-on. The lock comes with a spare key and it is relatively light for a metal chain, weighing around 5 pounds or so. I bought this lock for around $40, and I must say it is definitely a great budget lock, especially for students who have just bought a new e-bike or scooter and are afraid of thieves! Cons: The lock isn’t the most portable compared to a U-Lock. For U-locks, you can easily hook onto a bike or scooter while riding; however, chain locks are a lot different in that case and require you to at least have a backpack or bag on the handlebars as you ride. This could be difficult for some people, but as a student it's perfect for me since I always carry my backpack everywhere! Another con is definitely the length of the chain, which gives some limitations when trying to lock it around areas that you may find more secure. It is only 2.5 feet, so if you have enough money, I highly recommend spending for the extra length. Just remember to have the portability to carry it! Verdict: This lock is great, and I highly recommend it if you’re on a budget. If you are someone who is still skeptical, you can always invest in another Kryptonite lock or possibly just buy one of these variants with a longer chain capability. I lock it around my school every day and have no hassle with taking it in and out. Remember to always lock your belongings, especially your e-vehicles!
