“ Brand: Kryptonite / Type: Bicycle lock / Sports Genre: Cycling „
I live in Oxford, where bike crime is unfortunately high. In the five years I have been here, I have owned 3 bikes - one truly awful Salcano mountain bike (which was like dragging a bike rather than riding it), an excellent Specialized Sirrus for communing and a Dawes Giro 500 for road riding. I don't much care for the first bike, but the other two I literally cannot live without, and hence have taken every measure possible to deter thieves. Before starting, I think I should make it clear that if you have a remotely nice bike (>£200), you should never secure it with a cable alone. At the minimum use a D-lock through the frame. The cable should only be an adjunct to act as a further deterrent / to protect your rims.
Length - the Kryptoflex is a long cable, long enough to wrap through both wheels, the frame and an immovable object in a figure of eight. This may sound obvious, but wheels should never be locked with the cable in a mere circle / oval, as thieves need only slide the wheels off the bike, leaving the cable-cutting till later.
Durability - I have had my cable for 5 years, and in that time, no one has attempted to cut through it. I have had multiple friends suffer the dreaded bike theft curse, but no one has even tried to steal mine (at least from what I can tell). Whether this is due to the deterring effect of the Kryptonite name, the cable strength, or my neurotic locking procedure (always with a D-lock through the frame, and with locking skewers on the wheels), I do not know. Probably a combination of all, but if you live in a high-crime area, the extra deterrent effect is invaluable.
The cable itself is thick and does not look too easy to cut through (would probably take a minute or two as opposed to the 30s it takes to cut through some other cable locks). It is about 1-1.5cm in diameter. My only complaint is that it is very hard to transport around - it does not roll up well and is quite cumbersome. If ease of carrying around is important to you, then don't get this, as you definitely want to buy something that you will actually use. I have had numerous friends with nice bikes stop carrying this cable around for that very reason.
In conclusion - good for securing wheels, but if you have a nice bike, is definitely not secure enough to be used alone.
Its unfortunate that security is often something we think about too late. At the bike shop in which i worked, it just wasn't practical to lock up every bike individually at the end of the night and besides, we had sutters on the windows so they were safe. Right?
Wrong. After a break in and the theft of several expensive bikes it was the the kryptoflex we turned. Im not saying that this is an unbreakable cable but it's a great solution for locking up lines of bikes.
Its sturdy construction and rubberised coating make it easy to pass through the frames of multiple bikes on display without the scratches caused by chains or cables. Also the bright yellow clamps at each end are easy to see in low light and offer a visual deterrent.
The cable is heavy duty and with a sturdy padlock i believe the knowledge that thieves will have to spend longer once they've tripped the alarm makes this a no brain investment for any bike shop.
At 30' this is alot of cable, so domestic uses are fairly limited, for anyone wishing to secure a large number of items its a great solution.
golferinfr's Full Review: Kryptonite KryptoFlex Looped Cable 30' Bike Lock
In my other Kryptonite Flex 4 Foot Cable Bike Lock review you will get the details of why I had to buy these cable locks. It's not to lock up bikes, but business equipment. If it wasn't for the reasons that the police really don't investigate lawncare equipment because there are just too many of us doing it and half of them are doing it under the table as a second income and they can sell it too fast or go out of state to sell it. So I have to take matters in my own hands.
I bought 3 thirty footers for my zero turns and my other expensive equipment. With my riding mowers I ran the thirty foot cables between the engine frames and body's while taking all the batteries of of them but one. I have a funeral Home that wants stripes and their property to look good for every funeral even in the winter, except when snow is on the ground. With the zero turns I was able to put locks hidden under the electric clutches of the motors. I even did one thing better. With every mower I took the batteries out of them, I put a small padlock through the eye holes of the battery stems.
The plastice flex cable is very easy to maneuver through the mowers and making them taut enough for the looped ends to meet, The looped ends are around 3 inches and easy enough to put a lock through and secure your equipment. The braided steel cable is covered with a very strong plastic cover and at the end of the loops they are secured with harden plastic mold covering the end of the loop hole. Kryptonite has a wide variety of cable bike locks, some with tumblerlocks on them and others with combination locks.
Overall,If I can save $100,000 worth of equipment from being stolen, it was worth all the work from the last three days. As a reviewer, I read a couple reviews on them and everyone seemed pleased. Price $34.99 U.K.
Thanks for reading !!!
