Kryptonite Evolution 1055 Mini Bike Chain Lock, 1.8 Feet Long 10mm Steel Chain Heavy Duty Anti-Theft Sold Secure Gold Bicycle Chain Lock with Keys for E-Bike, Motorcycle, Scooter, Bicycle, Fence

Excellent product, Haven't had no issues or breaking with my chain - Its awesome for locking up an electric scooter a lock up a bike close to the gate .... Good price for the quality for sure. thank you.would definitely recommend, but not recommended for an over night lock up.

I've used this bike lock for about a month now. It is very compact and leaves me confident my bike will be there when I return. I like that all metal pieces are covered in rubber or nylon fabric. This protects my bike from scratching.I think the biggest consideration for anyone looking at this product is how heavy it is. This chain is not something you can attach to your bike. You definitely need a backpack or basket to carry this in. It's too short to really loop around your waist.The shortness benefits the use case two ways-- it remains pretty light without sacrificing cut-resistance. It also makes it impossible for an attacker to use a lever within it. I'm not having any of the difficulties others have reported about the key not being accepted.In comparison to the Kryptonite New York mini U-lock, I prefer to carry this one. It feels lighter.

If you need a lock chain then this is the way to go. The kryptonite chain that I bought saved me from inconvenience so many times whenever I had to stop at my college campus. It does have one issue where the key doesn't go through all the slots of the lock and it gets annoying because you have to fumble around with the lock in order to get the key fully set in but aside from that it's a very high quality lock and it has saved me from many attempted thefts.

Good, heavy duty lock. A bit heavy to transport, but a small price to pay for added security for an expensive ebike. The 1090 is just barely long enough for my 20" ebike due to the thick frame & fat tires.

The only issue to speak of is that the key will sometimes not turn fully when locking or unlocking. This mainly is due to not inserting the key past all the discs. Most users are probably not familiar with disc detainers and the idea is you usually have to do some rotating and counter rotating with the key in order to get it through every single disc .Once you do that, it should turn pretty smoothly if the chain isn't being pulled with too much tension.A 10mm hex link chain like this is not something a bike thief is likely to get through discretely. Most only carry cable cutters at best. They'll need power tools for this. Picking this core is going to require both a specialized pick and a somewhat advanced level of skill & experience. This should be more than enough security for most people.I got my 22" version around $50. The price a week later is up to over $70 at the time of writing this. It weighs a little under 5 lbs.I think casual cyclists greatly exaggerate the importance of weight. 5lbs compared to your body weight + the bike, + clothing and gear is maybe 2.5% of total weight? Which doesn't even slow you down by 2.5% if your route is straight and flat, where it's almost entirely about resistances and not gravity or inertia. If you do a lot of climbing, for sure look into something lighter.

We bought this lock for my sons 1200 electric Segway scooter. It locks perfectly and is right to the scooter and lock stand. It’s one of the strongest on the market and it is very secure.MAKE SURE YOU ORDER THE RIGHT SIZE. Small one for scooters.

Lock is really strong and sturdy, however I bought the 3 inch lock realizing it’s too short to lock the main frame of my bike or escooit’s not going to do the same job as it may be short

This has one of the highest ratings for Kryptonite's security by and it is a solid beast. I also like how it is chain links making it compack and pliable to pack on the go. Ends are just small enough to fit cable secondary security cables through the tires and seat. Bit the length is not long enough to go through the tire, frame and whatever bike rack you are parking your bike at. If you can get this same one in the next length up, it is worth it.
