Bike enthusiasts: would you recommend a good combination lock?

I like this one.

i don’t know if they come in “combination” because mine’s a key, but definitely go with a u-lock. at my university, literally thousands of bikes have been stolen by people who just cut the cable lock with wire cutters and rode off. needless to say most were never caught or the bikes recovered. i have a ‘kryptonite’ brand u-lock, and i also secure the front tire with a combination cable lock through it and the u-lock. sorry i don’t know the brand, the previous owner of the bike gave it to me for free.

I have this one. I wouldn’t wish it on my worst enemy. Worst lock ever.

I’m sure you know this but be sure to put that lock through the body instead of the wheel, I got my bike stolen once and I was only left with a front tire and it happened to my friend Matt 4 times.

Hey, aidje, that looks just like my bike cable. Does it never change shapes from that coiled up, spring-loaded position for you too? I have popped myself in the arm with that piece of crap so many times, or sent it careening across a parking lot. I’ve only used it three or four times and I was hoping it would stretch out a little. What’s the deal?

Definitely go with a U lock. Kryptonites are good. Depending on the place you live, you may also want a cable to secure both wheels. Where I live, it’s a must as thieves carry various tools. In some places, any old lock will do. Where do you live?

We live Western Maryland.
This is just for use while parked at school. I figure a combination lock will be lighter and no risk of losing keys.

I use a combination U lock. I got mine at Sierra Trading Post, and it happens to be on sale now.

I always use 2 locks when I have to lock up outside. I use a kryptonite U-lock and a cable lock as extra security. Don’t forget to lock up both wheels. All locks can be broken, but having 2 different kinds on one bike makes for a great deterrent. The only way to ensure that your bike does not get stolen is to keep it inside with you, and even that doesn’t work 100% of the time. Also, I tend to use locks that have keys instead of a combination. I have had combo locks that spontaneously change combinations on me, preventing me from unlocking my bike (although I blame myself for that). The downside of keys is that you can lose them.

For a U-lock, I recommend the New York Lock

And for a really heavy duty chain lock, I like the New York Fahgettaboudit

Any thick cable lock would be a fine addition for that rear wheel.

I haven’t had any such luck. I think it’s going to stay like that forever.

MAybe it depends on where you live, and what sort of threat level there is. Check this out.

@ BluRhino ~ that is funnily disturbing.

I would appreciate continued input on this thread, a lot of the suggestions are for good-quality locks, but this is the criteria previously stated;

* light
* combination-type lock
