  • Strong adaptable bike lock
Color: Gray
It's hard to believe this lock doesn't get the highest possible security rating. It's heavy and thick and the type of locking mechanism means that even when cut through, the pieces will stay locked in place, meaning it has to be cut through a second time before a bike can be stolen. Plus, when attaching it to a bike frame, everything is infinitely adjustable: the clip on the lock itself can be rotated through 360° and the bracket which attaches to the bike has a fabric strap which can wrap tightly round even awkwardly shaped frame bars (like the D-shaped aerodynamic ones). The bracket's receptor clip for the lock is also rotatable through 360°, so the bracket and lock can be fitted just about anywhere on the bike frame that's safe, without taking up the space needed for a water bottle. A quality product, highly recommended. ... show more

  • No brainer.
Color: Gray
Great product - high quality and works well. Best entry level Kryptonite lock on the market that even comes with an attachment to hold your lock while you’re biking. Keys are high quality and doesn’t get stuck or bend easily. Lock holder comes with a rubber strap so it doesn’t scratch your frame. Option to register for kryptonite’s insurance program where if your bike is stolen they’ll refund you up to $2000 (if I’m not mistaken). And they’ll also send you free keys for free as long as you register them. Awesome company, awesome product, would buy 10 if I had 10 bikes. After using for about 2 weeks, commuting in NYC, the only thing I would recommend is tightening and adjusting the holder every week or so just so the lock doesn’t accidentally get in your way while riding. ... show more

Es eficiente, funcional y muy seguro. Sólo me gustaría que hubiera más opciones, un candado de mayor tamaño. Gracias.

  • Works great but couldn't figure out bike holder
Color: White
Easy to use and nice small size. So far, my bike didn't get stolen! But couldn't figure out how to install the holder on my bike.

  • If I go crazy, then will you still call me Superman?
Color: Gray
My husband bought a fancy bike and for approximately 6.5 months he decided to “take his chances” with seeing if it would get stolen. It didn’t. I have no idea how, but said bike didn’t budge from the bike rack at his place of employment. But I’m a little crazy (a little?!) and constantly concerned so I surprised him with this lock for said fancy bike. It has yet to be stolen in the 3 months we have had this lock and I’m absolutely crediting this bike lock for our stroke of luck. It’s solid, easy to use, and locks. You’d need some pretty hefty bolt cutters to remove it. Will definitely purchase another for my own bike. ... show more

  • Works Perfectly To Protect My Bike
Color: Gray
I have a $2500 bike & this allows me to do errands & feel secure. Just the right size to easily find a hitching post around town. Not too heavy & I find it big enough. Usually carry in backpack.
