Kryptonite Evolution 4 1016 Lock Black 2018 Bike Locks Chain

The chain is just thick enough to require heavy duty tools to cut, the links and sleeve make it difficult to hold in place for an angle grinder, and the length allows me to wrap several times or stretch to difficult racks if I need to. The lock itself requires very specialized skills to pick. Not something run-of-the-mill thieves will know what to do with. I actually purchased two of these to daisy chain together for a long 10ft lock to wrap around 6 bikes on my car rack or in my garage. I have so much peace-of-mind knowing they're reasonably safe no matter where I go. It's a really good feeling! It's true tho, that these locks are heavy. Like, surprisingly heavy—Jacob Marley heavy. Not something I want to carry around on my person. The only other complain I have is that the rubber cuffs at the end of the chain sometimes get in the way of locking when I pull the chain to stretch in situations where the lock barely fits. Usually tho, I can grab higher up on the chain and the cuff is fine.

pretty damn good lock.

Like others have said, it’s heavy duty and should dissuade a would-be thief. It’s long enough to wrap the frame and tires, but that makes it a bit heavy. Need to use both hands, hold the ends, and push the “hole” end all the way in, then gently turn the key, don’t force it. I feel like I could snap the key off if I really wanted. That should not be an issue with constant pushing while turning the key.

I chose this lock because its robust construction should deter the type of bike thieves that may be lurking in my neighborhood. I am very unlikely to encounter "professional" thieves in my small city/countryside environment. I am convinced that the girth of the lock and chain will make it very hard for a random person with bolt cutters or small grinding wheel to cut through quickly. I expect that a professional lock picker could open it in about 20 seconds - but I don't think the average bike thief around here is a professional lock picker. The down sides for me is that the weight of this thing is heavier than you think so bringing it along requires wearing an extra 11 pounds - that feels more like 25 or putting it in a basket. The lock mechanism seems surprisingly tricky. Its a simple key, but sometimes you have to play with it to get it to work. I need to be cautious that the small uncovered area of the chain (where it fits in the lock), doesn't chip the beautiful paint on my bike while removing it from what the bike is locked to.

Great chain for multi purpose uses. We have electric bikes that we chain to our camper tongue and feel much better about leaving them outside.

My son won a new bike, valued at $700. Was not about to take a chance on it getting stolen... I love this chain! Solid, heavy, a weight you can feel. No issues since we've bought it, and it's been tested. Out at shopping malls, plazas, schools, stores, etc. This kid bikes everywhere, and every time he goes out, he comes back with his bike. It's been almost three months and no issues. Because of the weight, my son wears this like a sash across his body when riding, but other than that, we love it.

I measured it out and figured I knew how big this thing would be but it's hard to prepare for a chain this size arriving for your bike. This is 1/3rd the weight of my regular mountain bike and 1/7th the weight of my ebike, so you better have a means to attach it to your bike whether it's tied to your cargo rack or looped around something.I feel pretty confident locking my bike up with this thing during the day to go grab some food or groceries, that most aren't going to be interested in stealing my bike. It works like a charm with my ebike, where I wrap it around the frame & front wheel & a pole easily, so 5 feet was a good choice regardless of my surprise.The lock is a bit finicky to open but that's what some lubricant is for- in fact you can get lock lube on amazon which helps get these things working better and is something you'll need regardless to maintain your lock. So those that have complained they're straining their key are not doing a great job taking care of their lock.If you got an ebike with a cargo rack I think this will be a good option to help keep your bike safe- as long as you're not leaving it outside, unattended for hours and hours. For that you absolutely should invest in 2 different types of locks.

Exactly what I was looking for. Sturdy chains for my bike. They heavy but I have a bag to put them in while riding

Very heavy chain and very heavy lock. Feels like high quality. Very tough, and hard to pick

Rien à dire, cadenas parfait pour mon usage. Attention, vu que très robuste, lourd (faut savoir ce qu'on veut)!

Je l'utilise pour mon VTT électrique. Noté 8/10 à l'indice de sécurité Kriptonite, la chaîne est longue ce qui permet d'avoir de la marge pour l'attacher, voire pour attacher 2 vélos.Bon l'inconvénient, c'est que c'est lourd, mais on n'a rien sans rien !!!On peut enregistrer le n° de série, ce qui permet de refaire des clés si on arrive à perdre les 3 (dont 1 avec une led, ce qui est bien pratique) qui sont fournies avec le cadenas.

Sehr schweres Schloss, aber dafür wirkt es unheimlich sicher.Die Länge von 160cm reicht locker aus um unsere drei Bikes zusammen zu schließen.

Essa corrente com cadeado é muito boa e resistente. Eu comprei para minha bicicleta porque meu namorado tem uma e um bandido tentou cortar com um grande alicate e não foi possível. Sabemos disso porque foi tudo filmado e deu pra ver quando um cara tentou cortar e teve que desistir. Realmente indico. Depois que coloquei ela nunca mais roubaram minhas rodas da bicicleta.
