I hang my u-lock on the handlebars. I had to figure out the right way to hang it so it doesn't interfere with my turning ability or hit my knees. I used to use the frame mount that came with it, but that broke.

The problem with sticking it in my bag is sometimes if I go someplace without a bag or if I take it out of my bag for whatever reason, I forget the lock and don't realize that until i get to where I'm going.

I sometimes carry my lock around my neck, sometimes in the plastic tub I have on top of my rear rack.

In the rack box, sometimes in the handlebar bag.

I use a length of bungee cord to attach it to the periphery of my rear rack.

U lock in the frame mounted holder, cable lock in the rear basket.

Heavy chain and padlock permanently on guard rail at work. Ulock hanging on trekking bars all the time. A cable that goes thru seat and rack, always sometimes tied to ulock and sometimes secured with additional padlock depending on the errand.

What make/chain is that? Looks very thin and small to cram into a bottle holder. What material is the chain? Yah it looks very handy and slick to carry that way but I'm worried one day your wheels will be gone.

Bike's in a few pieces right now but you get the idea.

There is seriously no other place to put that holder on my frame. Down tube is too fat, rest of the triangle has cables running along.

The holder is starting to feel worn. Not sure how long it's going to last. Velcro padding on the tube and superglue on the hook sleeve to keep the rattle down.

For school I also have a 7' cable that I loop and wear over my shoulder, under my backpack.

edit: Stopped with the cable once I got bolt-on skewers. I don't consider my school a high-risk area for wheels. And the pictured method doesn't play nice with brake/shift cables once I lowered the stem. Currently bungying to my rack, and looking for a way to stop the rattle.

Where do you get that dog spray holder? How fast is it to deploy? Can you deploy while riding? If so how fast can you depoly while riding?

Also how secure and non moving is that Ulock mount? I'm thinking of changing my mount style for a high-speed low-drag setup. Right now I got my Ulock on a bungee cord and take me about 3-5mins to lock the bike and the same time to unlock and store the lock again. Kind of a hassle and keeps the window of attack wider if someone was to attack you at that valnurable (sp) moment.

I get asked this one a fair amount. I hang it in a metal bottle holder that's deep enough that it won't fall out but easy to grab. The bottle holder is strapped to the side of my backpack. There's a small support strap to keep the lock in place if needed.

I have a chain that I cut to the length of my waist. Wrap it around overlap a couple links then lock it.

I have a lock that comes in a coil, so I coil it around part of my bike, unlock it to attach my bike, and there we go.

I bike to so many other places besides work that leaving my lock at work just doesn't make any sense. I'm kind of surprised that Sheldon Brown recommends it. Perhaps he also leaves spare Kryptonite locks at his favorite grocery store and pub.

I bring my U-lock in one Mondays and leave it on the rack until Friday, so I have it for the weekend. Weeknights, if I bike somewhere other than home, it's to a few places that I am comfortable bringing it just inside while I grab something (Thai, deli, mom'n'pop grocery store, library.)

That said, I've been meaning to buy another u-lock, so I can leave one on the bike rack at all times, especially once my commute lengthens from 6mi to 10mi each way in a couple months.

when i was a messenger back in the 90's, i only had 5 clients (major volume though) so i bought 5 loops of 3/8" grade 70 chain, 5 keyed alike ABus Discus padlocks, and one Krypto U lock. I would leave a chainlock at each clients address, and just ride with the U lock (so i could stop for coffee, etc). worked out very well for my needs back then. When i left that company i gather up all my locks and redistributed them to the bike racks at my pub, the nightclub, the machine shop and other places i went to a lot.

I commute on a folding bike so I usually bring it inside my office. However I do bring a lock on days I need to run errands in the middle of the day. Having a folding bike (even with full 26" wheels like mine) can be a problem when attaching stuff to the bike. I put my lock mount on the front fork, opposite to the folding direction. It works out well, but pulls the wheel a bit when I'm at a stand still or have the bike propped up on something.

Hope that helps.

I keep it in my messenger bag. The bike rack at my office has maybe 10 locks left there and I've never seen them used (the rack is full, and there are still all those chains sitting on the ground).

in my large trunk bag,

in my messenger bag


but now im going to get one of those mini U locks

Either around the seat post, OR
strapped to my backpack with the bungie holding my pack to the rack, OR
in my pack if it's on my back.

It came with a mounting bracket, but I don't use that.

that looks like a great invention! Aerobar/Ulock clip on handlbar.

You heard it here first folks. So I got dibs on PATENT rights.

in my panniers, probably start leaving the lock at the school once I'm back on campus teaching in the fall.

I have a Tubus Locc rack, its made to carry an Abus U-lock, which I also have. I love the set up, lock is secure, doesn't rattle, doesn't interfere with panniers or top of rack, easy to get the lock on and off the rack, can do it with one hand.

Very, very nice! I wish more racks were designed to hold U-locks like this. I personally strap my U-lock to the top of the rack, but it interferes slightly with getting the panniers on and off and the bungee cord hooks have started to wear holes in my panniers

That is an awesome set-up, pedalMonger.
