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 ...

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 ...

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 ...

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?, ...

All bicycle helmets are subject to the same standardized set of impact tests during the certification process. If the helmet product passes, it meets the minimum criteria for protection, regardless of how much it costs, weights and which proprietary technologies it uses. The subtle point here is that the existing certification protocols are rather ...

I would lock the rear wheel. The problem of locking the front wheel with U lock is that there's no way to lock it easily (or at least I can't imagine one). The front wheel is attached to the fork, but the fork doesn't have a closed "loop" so there's no place in the fork where you could lock the front wheel. So if you lock the front wheel, chances ...

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.

The most important thing is that the frame is securely locked to a solid object. If you can also lock one or both wheels it’s nice but I wouldn’t worry too much. The rear wheel is more expensive but also harder to get out. If you take out one (or both) of the wheels you might be able to lock both wheels + frame to an object with a single long-ish U-lock. I ...

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 ...

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.

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 ...

The question is about crowds of people, but I'll answer from another perspective, dealing with crowds of bikes. I'd say you're better off locking your bike up in a location that has many other bikes nearby, rather than locking up in a location where your bike is the only one. First of all, crowded bike stands tend to be where lots of people are, so you get ...

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 ...

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, ...

MIPS has become common in at least mid-to-high end mountain biking helmets in the US over the last decade. The https://mipsprotection.com/ web site has some descriptions, but my general understanding is that MIPS systems have an inner shell next to the head that can rotate somewhat relative to the main helmet shell. This serves to reduce the peak (sideways) ...

Bottom Line: Nothing is perfect. You need to develop a strategy based on what parts you are willing to replace. I use a U lock and a steel cable similar to the pictures below and I take my quick release skewers with me. Here are some suggestions from other sources According to one maker of U shaped locks this is the best way to lock your bike: thread a cable ...

Interestingly, just locking the back wheel can also secure the frame if you do it in the right position, as shown in this post on pinterest: You can remove neither wheel nor frame because the wheel does not fit through the triangle; it keeps the frame in place. This is often a lot easier than trying to secure both frame and wheel, which is simply ...

This study is the most scientific resource I was able to find. It compares several rotation damping systems to a standard helmet without any additional safety measures. I made a quick overview with the most relevant data and figures. CONTROL is the standard helmet, and MIPS is the exact same model equipped with Mips. (ODS, LDL and SPIN are other safety ...

A well locked bike is relatively* safer in a crowded place. According to markelinsurance.com in "Bicycle Theft in the U.S." In the section "6 easy ways to help prevent bicycle theft" Lock it in a high-traffic area. Cyclists shouldn’t just look for a well-lit area to secure their bike. Ideally, a bike should be locked in an area with a ...

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 ...
