The simplest answers are ask for their ID, or for their car keys if they arrive by car. There are plenty of other options on various forums like https://www.bikeforums.net/general-cycling-discussion/446194-selling-bike-craigslist-test-rides.html https://www.bikeforums.net/general-cycling-discussion/687171-how-do-you-let-potential-buyer-test-ride-your-bike....

That sucks. I'm sorry that your bike was stolen. If thieves are willing to break into a locked garage, break into a locked and fully enclosed mesh bike parking area then cut two bike locks using power tools: there's not much you can do about it. If there are lots of bikes in the bike parking area you can make your bike a lower priority target by increasing ...

Buy more secure lock(s) for your bike - I have a Kryptonite New York Standard and a Kryptoflex cable that I leave in work for my commute. I also have a New York Fahgettaboudit Mini for using about town on my single speed (no quick release installed on this bike). Utilise new/better lock from above to secure your bike in a more productive fashion. Personally ...

A cheap ring lock like the one pictured below can be defeated in less than one minute with a screwdriver. Furthermore, even a good ring lock (one that that isn't easily broken and might take a few minutes to defeat with a screwdriver) has a fundamental and fatal flaw - the thief can simply pick the bike up and put it in the back of their truck or van. A ...

It is all subjective, but I would say that a public place is better (as I have previously answered to a similar question). Most bike thefts are opportunistic; unless you've got an especially desirable bike the theft is not about your bike, it's about stealing any bike. So the key is to reducing the opportunity to steal your bike: as you point out, ...

Bicycle Theft, Guide No. 52 (2008) gives details around bicycle theft in different variants, stages and from different perspectives, contains reference for theft data. From the report: Offenders Not all bicycles are stolen for financial gain. Some offenders may take a bicycle simply to get from one place to another, and then abandon it. Research suggests ...

In a situation like this, I usually don't fit any of the wheels in the support; instead I park the bike over the rack and just to the left or right of a loop, so that the lowest part of the frame is in close proximity with the loop. I then lock the frame and a wheel with a single cable (a U-lock might not work). Alternatively, you can place the rear wheel ...

I know you said 'I'm not going to find my bike', but it is definitely very helpful to figure out the spots where bike thieves try to sell your bike on. I have retrieved more than one stolen bike that way! In Amsterdam there is a service every Wednesday (in different locations) where you can let the number of your bike be registered and they will engrave it ...

Some of what does and doesn't work, based on two great sources: a study in Montreal, and the USDOJ's COPS program's paper on bike theft prevention: What Works: Adequate Locks I won't discuss the matter in detail since it's not part of the question, but adequate locks and locking technique are the most important method of prevention for most people. Both the ...

Firstly, these suggestions are only going to make it slightly harder to ride away with your bike. I've heard the most common thefts involve grabbing the bike or bikes and slinging them into the back of a van, in which case it doesn't make much difference. But against the casual opportunist/errant kid... Have a QR parts and remove them - saddle, pedals?, ...

It is effective against certain kinds of bike theft, particularly if you already lock up your bike effectively every single time (which is a good assumption if you're willing to go through the trouble to uglify it). Many people swear by it. For example, LDS missionaries in Taiwan repaint their new bikes poorly as a matter of tradition. As Daniel already ...

You definitely do not want to bend or misalign your derailleur, so you are right not to park your bike with the rear wheel in the rack. Your only option is to use a long, thick cable or chain to thread through the rear wheel, rear triangle, front wheel and rack. Using more than one cable or chain and adding a u-lock through the rear wheel multiplies the ...

Cash in hand. They give you the purchase price, in cash, and it sits in your pocket while they do the test ride.

In the end it might matter more WHO is around the rack (policemen, guards, janitors, public workers, parking lot workers, hot-dog stand owners, etc.) than HOW MANY people. I'd rather, when available, leave my bike under one lonely ever-present alert pair of eyes than in a crowd of anonymous passers-by.

As for the Kryptonite, cutting one side an bending is certainly possible, but in reality if you can cut one side, you use the same tools to cut the other. The tools needed to bend the link after cutting one side are almost certainly not portable, and why would you carry two tools when one will do. In comparison to the D-lock--if you can cut though 18mm, you ...

I'm answering my own question because I took a combination of the steps above, plus some other steps. I took steps to make getting it back in event of theft more likely: registered the bike with the Chicago police: https://portal.chicagopolice.org/portal/page/portal/ClearPath/Online%20Services/Bike%20Registration I plan to register it with https://www....

This isn't uncommon in our neck of the woods. If you're a light packer, taking your bike the the airport can be a huge money saver. If your airport doesn't have a bike locker, bring two trusty u-locks with you. Use one u-lock to secure your front wheel and down-tube to one pole, and the other u-lock secure your rear wheel to another pole (please, never use ...

There's nothing you can do if the storage area is not under constant surveillance. It can take as little as 2 minutes to grind a U-Lock. The only real solution is to keep your bike in your apartment. In the meantime, check to know how the thief was able to get in that area ? did he came via the garage door ? the front door ? Did he enter while someone ...

For the longer term, ask your employer to provide proper bike parking. The device you picture is completely unsuited to parking bikes. As you've observed, it's impossible to securely lock your bike to them. If your bike is stolen, your insurance will refuse to pay up unless it was securely locked. Parked there, it wasn't. The one shown in the photo is even ...

Get folding handlebars so you can carry the bike up the steps into your apartment. Make room for it inside (just get rid of something else you don't really need such as an old chair, an old bookcase, an old girlfriend...).

I think that picking up a second bike is definitely a good approach. Not only does it allow you to not risk your more expensive bike getting stolen, but it allows you to have a bike more suitable to commuting. You can put fenders and racks on your commuting bike. Perhaps wider tires if you want something a little more comfortable. Since you are good with ...

I lost a few bikes to theft when I was in university. It stunk. I took to buying used bikes (probably from bike thieves). I wrapped the frame tubes of my (otherwise nice) bike in peelable masking tape, then smeared them with grease. Nobody wanted that ugly bike. It worked to prevent theft; I kept that one for many years.

Funny enough, the parking garage may actually be less safe than a well-exposed outside location. When I was commuting between the cities of Hamburg and Berlin I locked my (500/1000$) bikes at the train stations, sometimes for weeks. I made sure to detach and lock my front wheel together with the back wheel and frame though, on some steel pole or railing, ...

Unless you really care how the bike looks and about extra 50 grams on the bike... Find a piece of old chain. Wash and clean it. Find a piece of old tube, best would be road bike tube. Measure the distance between saddle rails and top chains - double it and you'll need that much of tube and chain. Cut the tube and chain to the measures. Pull the chain ...

I've seen videos showing people stealing bikes amidst a crowd of onlookers while no one intervenes. Locking in a crowded place isn't necessarily going to save your bike. On the other hand, lots of bikes are stolen from locked garages. I'm not aware of any statistics about what storage method is safer. I've never had a bike stolen, but from what I've heard ...

Those don't look that great. Students would need a long cable lock in order to lock their bikes. There's no way that they could do it with a U-lock. And the weight of the bike is resting on the spokes, which is not good for them. Also, I'm not sure what level of school you're talking about, but I imagine an elementary school child might have a hard time ...

I left my bike at the airport for a week and would do it again. It seemed to be the safest place in the whole city, safer than my home. It depends on where the bike racks are; here in Edinburgh they are right next to the entrance to the departure check-in hall. It's inside the vehicle perimeter, and a security guard stood with a submachine gun next to it. ...

So, if understand correctly, the lock is mounted on the down tube as sketched below? If so, you could try placing the "U" part of the D-lock in the frame mount, hold one loop of the cable on one end of the "U", wrap the cable around the seat post & up over the top tube, then back down to the D-lock & then place the locking mechanism on (also as ...

You might have a bit more luck doing things the other way around - go to the Sold Secure web site and read off a list of compliant locks. When I was buying, I took this approach, chose the locks and then bought them online. Also, bear in mind that Sold Secure originated in the UK, so possibly lock manufacturers who sell mostly outside of the UK market might ...

I went on two bike tours in 2017 and 2018 around North America, for 3000+ miles each, and this is what I did to secure the panniers to the bicycle: Nothing. That said, I did take some precautions. Whenever possible I locked the bike in a highly visible location, preferably with some security cameras pointing at it, and preferably visible inside the ...
