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.

Very sturdy, easy to use, and has been an effective deterrent from theft for several years.

Used this lock everyday for 2 months in LA to secure 2 500$ bikes. Someone stole my bicycle headlight but not my bike! Thing is a beast and you'd be hard pressed to remove it with the great lock core and excessive heft. I'd never leave any bike out on the street overnight but this chain will keep you covered if you have a little common sense.

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.

Finally bit the bullet and picked up a solid lock for my mountain bike. Fits around the front triangle on my mountain bike and easily reaches around to lock it to my 1up bike rack without having a lot of excess. However, it would not be long enough to go through the triangle, front wheel AND rack. While I'd still never leave my bike unattended for long periods (even with this), it does help when traveling and needing to stop at a rest stop with my bike on my car. Easy to lock/unlock (no hangups in the internal mechanism), and it's nice that it has a lock cover to prevent dirt and grime from getting into the lock. The outer material prevents the heavy metal chain from contacting my bike. Overall really happy with it!

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.

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.

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

This product is great, but quite heavy. Probably not the product you would easily carry around on a long ride. I chose this one as there is protection on the lock and chain to avoid scratching paintwork.

Had to mountain bikes stolen from car rack. Existing cable lock chopped through. They will need an enormous bolt cutter or angle grinder to get through this.

Di sicuro non c'è niente, ma questa catena rappresenta a mio giudizio un'ottima soluzione per motociclisti cittadini che hanno esigenza di sicurezza e durabilità. La catena si distingue per la sua robusta costruzione, offrendo una resistenza eccezionale contro il taglio e il tentativo di scasso grazie alla sua catena in acciaio temprato di 10mm. Il design integrato della catena e del lucchetto rende il sistema di sicurezza estremamente pratico e facile da usare. La lunghezza è ideale per legare lo scooter a vari oggetti fissi, offrendo versatilità e comodità. Inoltre, la copertura in nylon della catena e la protezione in gomma protegge i cerchioni dai graffi. Il cilindro del lucchetto dovrebbe essere progettato per resistere a tentativi di picking e drilling (ma si sa che le catene vengono più cha altro tagliate o aperte con cesoie idrauliche) La catena è anche accompagnata da un set di tre chiavi, una delle quali è dotata di una luce a LED integrata, una caratteristica utile in condizioni di scarsa illuminazione. In definitiva ritengo di aver azzeccato un ottimo compromesso tra qualità e prezzo, sicché la consiglio.
