Locking your bike in public areas

Question

I recently saw a small clip about how to securely lock your bike. I was wondering what are your tips for minimizing the chances of getting your bike stolen.

Here are a few of my tips:

• use 2 chains
• take the saddle off ( makes it less attractive, especially in a bike rack )

Answer 1

Lock related

• Have a better lock than the bike next to yours.
• At the very least get a lock such as this one: http://www.bicycleworkshop.co.uk/products.php?plid=m2b1s93p186 they are relatively difficult to break and are easy to operate meaning you'll lock your bike as a matter of course.
• Don't use a cable lock. Bolt cutters snip them in like 5 seconds.

Location

• Use a chain lock to attach your bike to something, but (and this is important) never lock your bike to something that would make it inconvenient for someone else.
• Lock the bike to something solid.
• Never leave your nice bike outside overnight or for extended periods of time during the day (but you're already doing this because you don't want to leave your precious bike out in the rain right?).
• it should be in a reasonably populated, busy area
• if you park in one area frequently, try to move around a bit - thieves might notice a decent bike often in the same place

Bike Tips

• Get a cheap, ugly secondhand bike for city use.
• Get allen key skewers as opposed to quick release
• Keep your lights and/or cycle computers with you, not on the bike

Answer 2

To avoid bike seat being nicked

1. Take it with you (not always practical)

2. Use a cable or chain to attach it to the bike frame. These are made commercially, but even a fairly token bit of wire rope works - the people who will cut that will generally also cut your lock.

3. Get allen key skewers as opposed to quick release. This reduces the chances of theft, but in some cities, thiefs carry allen key sets.

4. Buy a proper locking bolt for it. One example is pitlock. If you're buying those for your wheels the additional cost for a seat bolt is low.

Take number 3 a step further. This is a great tip I learnt from a NYC bike mechanic: - Find a ball bearing thats same size as allen key hole. - Dab some grease/vaseline in hole - Place ball bearing in.

= Only way to get ball bearing out is with a magnet.

Answer 3

In France, a bike coding system exists. It consists of a unique engraved code and a central database indicating the owner of the coded bike and whether it has been stolen. This both makes the bike less attractive and easier to recover when stolen.

Of course all the advices about locks are relevant even with this system.

Answer 4

A recent article in the Guardian: Bike thief tells how to stop your cycle from being stolen:

• don't use a cheap lock
• don't assume CCTV will deter
• put it in a popular area
• if you return to your bike and it's punctured/damaged, move it as it could be that a thief has done it to buy more time
• if you park in one area frequently, try to move around a bit - thieves might notice a decent bike often in the same place

Answer 5

Here's how I deal with the three main threats:

1. Keep the bike from being stolen with a small, chunky u-lock.
2. Keep the components from being removed with security skewers
3. Make sure the structure you're locking to can't be dismantled.

U-lock: I use the Kryptonite Fagheddaboudit lock, which maybe a bit of overkill in retrospect since it's quite heavy for a u-lock. Small locks prevent thieves from fitting prying jacks inside the U.

Security skewers: These replace your quick-release skewers. They can only be unscrewed with a custom key that comes with them. Each key is different, so these are much better than simply using allen key skewers. They're pricey (~$80 for the two wheels, headset, and seat), but unlike a cable lock, they secure not just your wheels, but your front fork and seat as well. They also weigh nothing, require no cable-wrangling each time you park, and can't be clipped. I've found them to be well worth it. I use Pinhead skewers: http://www.pinheadlocks.com/

Verify what you're locking to: I know a guy who avoided bike theft in NYC for years using the above two tools, but who was finally undone when he locked his bike to a workers' scaffolding at a construction site. The thief simply removed the cross-bar that he had locked to, and made off with the bike. Another common honeytrap are those removable stop signs (the kind where the post is attached to a post stub in the ground, using a unscrewable bolt).

Answer 6

I've watched Youtube videos of people breaking locks:

• Cables: little bolt-cutters, concealable in jacket - about 2 seconds
• Heavy chains (as used for motorcycles): huge bolt-cutters with 4-foot long handes - up to 20 seconds
• U-locks: either an angle-grinder (requires AC power) or a hydraulic car jack - about 4 seconds

Executive summmary:

• Use a chain and/or U-lock, not cable
• Don't park a U lock next to an AC power outlet
• Keep chains off the floor if possible
• U-lock should hug the bike (so that they couldn't get a car jack in to prise apart the U lock without also destroying the bike)

Answer 7

If you must lock your bike in a public, unsecure area, firstly make the environment as hard to work in for the thief as possible:

• ideally make sure it's well lit
• it shouldn't be hidden away in a dark alley
• it should be in a reasonably populated, busy area

That way, even if your bike looks attractive, the thief isn't going to be able to be particularly keen on working over your preventative measures.

It's a harsh tip, but make your bike look less attractive: muddy, tape, bad paint job, old. I know bikes are about self-image, but if your bike doesn't stack up well against the one next to you, then they'll go for that one.

Remove all bits that are easily removed. Replace your Quick Release seat stems and wheel skewers with lockable ones. On my commute bike I carry a spanner, not a QR wheel.

Answer 8

Make sure that the object that you're locking to is actually firmly attached to the ground. I've seen enough poorly maintained bike racks where it's possible to lift up one end and work the chain or lock around. Also, locking up to a pole, parking meter or sign? are you sure that no one is going to lift your bike over the top?

As long as you can find one, I suggest always locking up to a well maintained public fixture meant for locking bikes to.

Answer 9

Use two locks of different types (eg Chain and D).

I've felt pretty smug in the past when I've come back to my bike to see one of the locks snipped, bike still there.

Answer 10

Lock the bike to something solid.

Put the bike somewhere it is in view of a lot of people and lit if at night.

Try to put your bike next to other bikes that are worth more and don’t have as good locks

Using two different desings of locks is a good option, but you then need to transport both locks – see these questions on locks

You may find you enjoy yourself better if you have a cheaper bike that you are not so concerned about being stolen.

Answer 11

I make it a habit to remove all the lights & computer & lock the bike in a VERY public area for short stints. If I am on tour and check into a hotel I will take the bike into my room with me or make arrangements with the lobby staff to keep it locked in the lobby. I haven't had a problem with any of the hotels (big or small) regarding security of the bike once I explain the situation to them.

Answer 12

I live in a big city, ride frequently, and have had a couple of bikes stolen. These days, I:

• Have a modest bike,
• Try to lock up in a visible place,
• Don't leave my bike outside overnight,
• Keep my lights in my bag, not on the bike,
• Use a good U lock, no bigger than needed, and
• Use locking skewers to keep my wheels and seat from going places.

So far, following this approach, I have had the same bike at least 5 years, with nothing stolen from it.

Answer 13

After viewing countless videos, blogs, reviews, etc. this is the best page on locking I could find.

Excerpts from the page:

• Lock the bike to something that is very strong, very securely anchored, and cannot be disassembled by thieves, such as a parking meter.
• Ensure that the bike & lock cannot be lifted over the top of what you're locking it to.
• Two complete locks are better than one, especially if both locks are attaching the bike to separate strong immovable objects. Locking the bike in two places also inhibits thieves from using the bike as leverage to break your lock. Whether they succeed or fail, they'll damage your bike if they try.
• As a rule of thumb, cable locks are relatively vulnerable. Do not use cable locks as a primary lock, and only use them as a secondary lock if you are satisfied with the limited protection they offer.

...and there's a lot more there in the way of detail.

Answer 14

I know it sounds incredibly stupid, but getting a bike with a striking color (such as this -love it btw) might reduce at least a bit the chances of getting stolen. I've read it happens so with cars, so I figure it might apply to bikes as well.

The reasoning behind it is that it draws too much attention and it is harder to sell.

What do you think?

Answer 15

I like these tips from the Kryptonite guys. Here tha basic:

• Use at least one U-Lock (better with aonother kind of lock)
• Release the front wheel and lock it with the back one
• Don't leave space for a tool to break your U-Lock.
