U-Lock and Cable or 2x U-Lock?

Can you use security bolts to make your saddle difficult to remove and then use one U-lock to lock up the frame and bike tire and then a second for your front tire, or do you have to use a cable and a U-lock? Could someone show some pictures of a bike properly locked up?

How far you want to go in securing your bike is up to you and how much weigh you want to carry.

At a minimum, you need to secure your frame and both wheels, and a U-lock+cable will do it. Double U-locks will work but are heavier. If I were to have two different locks, I would get different types of locks (U-lock and cable/chain lock) since this requires more tools for a thief to defeat.

Security bolts on the saddle are a good idea.

Every system can be defeated, it about making the thief go on to the next bike.

If you have a permanent rack space at work, you can leave a tough U-lock there during the night.
Then you can take a cable lock with you if you leave the bike for a short time somewhere else.

The amount of locks you have should depend on how much you are willing to spend and carry versus the length of time your bike is parked, where its parked, how good the area is, etc. Lots of factors.

Pitlocks have a negligible weight penalty, so the only issue is making sure to keep the small key nut with you when you ride. I'd recommend buying the ones that secure the fork and brake bolts. With Pitlocks installed, you can then carry a decent U-lock and a small cable to wrap through the front and rear wheels. The cable isn't for any real security, its just to let a would-be wheel filcher know that the wheels are not theirs, without them having to closely examine the bike and notice the lack of quick releases.

That's not true if you have something like this --

http://www.rei.com/product/721699?cm...20with%20Cable

It doesn't take 2 tools to defeat the U-lock and the cable... if you defeat the U-lock, the cable will slip right off. If you really wanted a 2 tool defense then you would need 2 separate locks, not a combo lock like the one above.

Anyways, I think a combo U+cable lock should be fine. Having 2 U locks is just too much hassle.. added weight, having to carry 2 keys, more expensive, etc

I use 2 u-locks. I am able to leave both of them at work. That way I can lock both wheels and the fram to the rack and my bike is way harder to steal then the other 30 or so near it. I work on a college campus.

I also have a 3rd u-lock I can carry if I need to stop somewhere on the way to work or home, but I do not carry that one unless I plan ahead on stopping somewhere.

I, like many people, carry a quality u-lock and a cable lock. Unlike your statement above, my cable lock from Trek has a built in combo lock and is relatively secure. I only have to carry one key for the U-lock and IMHO I don't think many people would bother with a cable and u-lock setup without a separate lock for the cable. The weight gain isn't high for the extra lock and you get the added security.

I run my U-lock through my back tire sheldon style and my cable lock is long enough to fit around my front tire, frame and bike rack. This means the easiest way of stealing my bike is to cut the rack. So far it has been very reliable and teh no cuts on my cable and u-lock are evidence enough for me to believe that it is an effective deterant to thieves.

There are many videos on youtube worth viewing. Concerning looking for pictures.

I agree with what envane said.

Concerning your seat, I think it was a similar thread here that I saw the idea, maybe not, but you could take an old/extra bike chain and use a chain tool to shorten the length appropriately then run it through your frame and wherever works on your seat. I like the idea myself, and one day I will get around to doing it... Anyway by doing that you are carrying extra chain links in a more useful fashion, and its unlikely anyone carrying a chain tool with them would want your seat. Sorry I don't know chain terminology that well, I was not able to word this as I have liked, but I think I got the point across.

I'm a fan of the Pinhead locking skewers, that replace your quick-release skewers and require a special key to undo. They are normally around $50 for a set (pricey), but I think a good investment. Usually I just use my mini Kryptonite U-lock to lock my frame and rely on the locking skewers to protect my wheels, but if I'm leaving my bike somewhere sketchy or for a long period of time I'll also use a cable through both wheels in addition to the skewers and the U-lock (but I also work in downtown Oakland).

I totally see the logic in Sheldon's method, but it feels weird not to pass a lock through the frame tubing.

Oh, and Pinhead also makes a lock for the seatpost clamp and a locking headset cap. As with the skewers they are expensive, but less expensive than replacing components.

+1. I also like having the cable lock with me on the ride home as if I run errands it allows me to secure the bike to non-ideal objects. Not good for a long time but fine for a quick run into a store.

Either u-lock and cable or 2 u-locks should work. Some believe that 2 u-locks are stronger.

Here is another site on locking technique http://www.mechbgon.com/lock/index.html

A good read on bike locking tips http://quickrelease.tv/?p=327

There's your photo. Let the air out of a tire and paint your bike entirely red just for good measure.

Holy Crap that is awesome.

+1,000,000

I especially like the U-lock just dangling from the pedal.

I'll chime in and say that a friend's bike was locked a la Sheldon. The thieves cut the rim and took the bike. Sheldon didn't think this would happen; I know otherwise. I have a lot of respect for the man - he knew more about bikes than I ever will - but he's wrong about people not cutting the rim. Most people lock up their frames and their front wheels, so getting a rear wheel to replace the one that got butchered shouldn't be a problem for a thief.

The frame is most expensive - lock it first. The rear wheel is the second most expensive - lock it second.

Currently I use a cable/U-lock combo, but no 2nd lock for the cable. All the cable does is secure one tire to the rest of the frame. Cut the cable and you could get the back tire. Cut the U-lock and you could get it all. I would like a dynamo hub in the front and an IGH in the back. If I do that, I plan to upgrade my locking strategy to add these: Axa Defender

At the present, my wheels aren't worth the effort to steal, so they're not worth taking too many extra locking precautions, but if that changes, I figure I'll upgrade.

But what's been said before is correct: two kinds of locks should take more work to defeat than two of the same lock. But it really depends on how likely you think it is that someone's going to take a part of your bike. I figure my cable means there's an extra step for anyone who just wants to grab my rear tire, but my rear tire really isn't worth the effort, so hopefully they'll go elsewhere. It will require more effort to defeat the U-lock, but most bike thefts in my area seem to be crimes of opportunity. As long as I don't leave the bike completely unlocked, I feel pretty safe.

For this reason I use a combination of sheldon style U-lock and cable lock. Also for clydes and other cyclists that invest in the expensive rims that are built extra tough I doubt that thieves would be able to use a hacksaw on those. New rims on x-mart bikes are cheap and I imagine would be easy to cut. You didn't tell us what kind of bike was stolen either. Was it a cheap bike where the wheel might just be worth more than the frame or was it a $2000 roady? If the latter was the case then he should have had more than just a U-lock on it.
