Best Overall: Kryptonite Solid Lock

Buy on Amazon

The kryptonite solid lock should be able to handle its purpose and duties with ease. All the tumblers and locking mechanisms have a graceful ease to them that ensures the owner that their bike isn't going anywhere. This lock will scare off most anyone interested in trying to steal your vehicle. The chain itself is made from an ultra strong and tough triple heat treated manganese steel. The length of the chain is ideal for bike racks and narrow poles so if you find yourself strapped for locking points you might be in a pickle.

The lock is supple, covered with kevlar to protect your bike. The protection is only for one year against lock picking only which most bike thief don't do. It comes with the keys, it is easy to lock and unlock.

• Very sturdy and easy to use
• Great thick chain that can protect your bike from most thieves
• Good investment for long term

Best With padlock: Kryptonite Cable Lock

Buy on Amazon

The kryptonite cable lock's material feels more premium than its price would suggest. Full sized bolt cutters are about as discreet as a zip cutter which will absolutely make it through your bike. Beyond the actual security features, it is an imposing visual image for security on your property. The chain is also long enough to chain up your bike rack to your rv or vehicle. The lock mechanism is smooth and a sliding cover is provided to keep the keyhole clean.

The lock is very user friendly and sturdy. It is almost 16 pounds so it is heavy. The chain is tempered so it is practically bolt cutter proof. This lock comes with a guarantee against loss so it is well worth the cost, especially when you consider what you paid for your bike.

• Heavy with thick links and not easily breakable
• Very rugged chain and lock, but heavy
• Propane tank until ready for use with emergency generator

Best With Flex: Kryptonite manganese Steel

Buy on Amazon

The kryptonite manganese steel's superior materials makes sure that it ages well with use. It is the lightest, most well designed form of a heavy duty "maximum security" chain that kryptonite offers. It is still long enough to go around your frame and through your rear wheel and chain. It weighs in between 6 and 7 pounds which, while heavy, is more than reasonable for the protection it offers.

The lock has a wonderful noose in the chain allowing you to shorten the length of chain in use. It is much easier to transport on the bike wrapped around the frame and the kryptonite pad-lock is more solid and easier to use than the larger u-lock. The provided cable is great for securing wheels. The noose feature also allows various ways to lock up.

• Looks solid enough to withstand a bolt cutter
• Super flexible, great for city biking
• Heavy and versatile lock for city bikes

Best For One Or Two Bikes: Kryptonite Great Lock

Buy on Amazon

Best part: kryptonite great lock costs comparatively low and it is available to ship in 24 hours. A 6 or 9 inch U-lock is much more secure, and can be fastened to the frame, or carried much easier. The chain is long enough ( 39 inches) to lock up two bikes if the are right next to each other. The chain is enormous but that is a good thing and you don't need to worry about the weight so much because it fits very conveniently around your waist while you ride and you don't even notice it's there. The lock itself is great as well, providing no leverage for would-be bike thieves.

The fine print in the Anti-Theft Protection says you get the cost of your bike back ONLY if you still have evidence of the broken/failed lock AND a police report AND proof of purchase of the bike AND it has been registered with Kryptonite. The lock loop is a tidy size, chain segments fit through the cast spokes of the wheels, the length allows chaining it to a large-diameter object, (provided it's close) and it stores nicely in the seat storage. It will come in handy if you are ever in need of road side biker weaponry.

• Excellent quality and very heavy duty
• New and hot release

Best With alarm: Kryptonite Best Lock

Buy on Amazon

The kryptonite best lock might be a relatively new release, but it's still nothing short of impressive this year. It is a lot of weight to lug around on a bicycle. The'shackle' is a full size ulock. It is a long chain that can lock several bikes together. As far as function the locks work well and the chains are smooth and well built. This is a great option to lock the entire bike, from the front wheel, to the frame and back wheel all together in the streets.

It protects your investment with the best security possible. They would also make a great Halloween costume accessory.

• Perfect length for 2 bikes through all wheels
• Heavy, long enough, great and easy lock to use
• One of the new comers and featured product

Best For home: Kryptonite end Link Design secures Chain

Buy on Amazon

The kryptonite end link design secures chain might be a relatively new release, but it's still nothing short of impressive this year. The hoop design of the Noose is superior to regular chain designs because it doesn't waste extra links. It works great, kinda heavy but if you need the security for your area definitely get this. It's a reasonably priced lock and it does its job but it can be a little user unfriendly at times, 3 stars.

This is a super beefy lock, it weighs an estimated 10 pounds. Over time, the rubber that covers part of the last (the connecting) ring works its way to cover the ring entirely, which prevents insertion into the lock. It's over 5 lbs, and be sure to keep the lock to the side, or bumps may offer an unwelcome surprise. The High security disc-style cylinder is pick and drill resistant.

• Great size, perfect for the person who occasionally needs to lock their bikes
• Feels safe, heavy duty, easy to use
• Delivers what they promise

Best For holding Bluetooth speakers: Kryptonite series 4 Chain

Buy on Amazon

Best part: kryptonite series 4 chain costs comparatively low and it is available to ship in 24 hours. It is really big, if you position it well you can use it as a bottle carrier too. It works great with just the velcro. It is easy to use chain carrier that transports the following integrated chains. It is good for holding bluetooth speakers. They could make it oval in shape so as not to be continuously nudged by the knee while pedalling that is if it’s hanging by the strap. It is easy to install and keeps the chain out of the way. The tube-r is low on the bike so it helps balance and balance. It fits a gatorade bottle no problem.

• Great chain holder, fits non-brand chains
• Good investment for long term
