Photos of locking methods

This is the method I use every time I can. However, sometimes I use two locks- chain for the front rim and frame, U-Lock for back rim and frame.

no picture, but I do something similar to you. My lock won't fit around the frame and rear wheel, so i just put it to the rear wheel inside the triangle of the rear wheel mount. Effectively does the same thing.

If i want to take ( not steal ) your bike, i need a large bolt cutter for the chain and a hack saw for the U lock, seriously,that's what i will do if i want the bike and you can't stop me.Oh, i am not a thief,just my 5 cents ( inflation ).

Actually my friend, the U-Locks on Youtube (and there is only a few videos) are very cheap quality steel. And if you have noticed even those oneís take a few minutes. Now, try sawing through a Kryptonite NY U-Lock with a hacksaw- thatís another story! And to further increase confidence, there is no video on the Internet of a Kryptonite NY U-lock being breached while properly attached to a bike. If you are really going to prove that a lock can be breached then you have to breach it as it was meant to be used.

Keep the photos coming!

Heh, heh... I tried sawing through a Kryptonite U-lock once... and only once. After 2-hours and 10 saw blades, I had made a jagged grove only 0.5mm deep. There's a reason Kryptonite has a guarantee on their locks and very few others do.

I ended up dragging the bike to the machine-shop next door and used their plasma cutter. Still took some effort with that, but we eventually got the lock off. Definitely not something you can do inconspicuously at a bike-rack on the street.

My girlfriend once lost the key to her bike lock. Luckily, the bike was just locked to itself in our backyard. One long walk to the LBS, and some time (10 minutes) with the angle grinder later, the Kryptonite evolution fell right off.

My usual lockup strategy...







And this... the best security feature here was the two guys having a beer 10 feet away.



Folders are great...



Very few of my bikes have quick release anything.

Any cable can be breached pretty easily with a bolt cutter so they are only good as a secondary to secure a front wheel and even then, it is often better to secure the front wheel to the rear wheel or use a second u-lock.

A good shackle is going to require a good deal of work with a hacksaw and the time it takes to go through one is what makes shackles so effective... any sensible thief knows that with every minute that passes their risk of being caught increases.

With enough open space a bottle jack can be used on lesser shackles so using the smallest shackle possible or a filler like a Bad Bones will prevent this. I have tried to cut through the Bad Bones and with a good hacksaw (and with the bar in a vice) it was not that hard to do.

Kryponite shackles use very good steel and are all very hard to cut with hand tools and a bolt cutter won't do anything but leave dents in them.

of course, power tools can cut through just about any lock.
if they can't get through the lock, they'll go after the rack.

always wise to immobilize one wheel since a lock attached to the frame when the rack is cut serves no purpose.

maxim recently did a test run of 3 type of locks, onguard doberman 5030 (cable lock), kryptonite NY fahgettaboudit (chain/padlock combo) and onguard brute STD (u bolt).while they were able to cut through all three, using an angle grinder for the U lock and chain, the cable got snipped by a bolt cutter, but the brute won there test because it was nearly $50 cheaper than the kryptonite

At my hacksawing rate, it would have taken 42 minutes to cut through the 18 mm shackle.
I like how he hypothesizes that it would have taken him 42mins to cut through it. There's actually an even harder core compared to the outer material.

still, it manages to be the best of the lot.

This is one of the better locking schemes I have seen. I think any thief would be highly deterred even trying to steal that bike. It's probably safe to use quick releases with a setup like that.

What's on top of that post though? I've seen bikes locked to parking meters stolen because the thief just lifts the bike up and over the parking-meter.

It's an 8 foot traffic sign just outside my house that I used for demonstrating my lock up strategy... if someone wanted to get my bike off that post they would have to remove the anchors or the multiple signs that are bolted to the post.

Besides having a solid strategy you also need to know what to lock up to and pick your locations well as that has a great deal to do with how secure your bike will be.

Lock it to a hydrant post in an alley and you will give a thief all the privacy and time he / she needs... lock it to a fixed stand in a high traffic area where there are lots of bikes and a thief will have to be pretty brazen.

I will even pass on isolated bike racks and lock up to secure posts and meters that are right in front of business doorways because of the higher traffic... my lock will not pass over the top of a parking meter and out meters are extremely secure to prevent their own theft.

I see bikes shackled to chain link fences a lot... this stuff is easy to cut through and I have seen holes in fences where I am sure a bike used to sleep.

i've seen a kryptonite keeper (their least expensive u bolt) overcome by some kind of tourniquet. the tines of the shank were squeezed together, and because of the shape of the end of one of those tines, the cylindrical piece just fell off.

moral of the story, don't depend on one lock, or one type for that matter and the more locks, the better.

I usually lock my front wheel and frame to an object with a u-lock (the front is QR). I use a sturdy kryptonite cable to lock the back wheel to the frame (not QR, not a very valuable wheel). If neither were QR, I'd probably do it the way pictured above. It would probably be more secure, as you can get away wiith a smaller lock, which would be harder to pry open. Maybe I will ditch the QR on the front.

Virtually any lock can be defeated... be thankful that I am not a bike thief as my experience as a mechanic has allowed me to explore many methods for removing every kind of key-less locks.

Those keepers are a fairly tough unit for the price and a good compromise when I don't want to bring my 3-4 pound double pinned shackle with me. I believe Kryponite has improved their design so that compressing their lock will not allow it to open either... the hooked end of the shackle sits quite deep in the body of the lock.

There is a reason they back their locks against theft.

I also have extra u-locks and will carry two if I think I will be in need of higher security / theft deterrence.

If I was a thief I would look at my bike and have to calculate that I could get that beautiful front wheel with little effort, that I might defeat the keeper although it would be a pain due to the lack of open space, and the double pinned mini would keep me from riding away as it would need a lot of time with a hack saw or require a power tool to remove.

This is how I lock my bike when I'm at the library. I also have a Topeak bicycle cover that I put over it before going inside.



That's using both a Master Lock U-Bolt lock and an On Guard cable. The cable goes through both wheels and the loop at the top of the bike rack and the U-Bolt goes around the frame and the post. As well as having an On Guard cable securing my saddle to my frame.
