This depends a lot on the city; different cities allow you to lock up to different things, and have different crime rates.

For example, I've been to major European cities where a lot of the bikes were happily locked where they would have been stolen in minutes in New York City.

I'd first start by removing things that could be easily stolen (lights, seatpost, etc.) or fastening them permanently / locked to the bike (e.g. using pitlocks on the seatpost). You can also glue in ball bearings into hex heads. Pitlocks can also be used on the wheels as an aide to locking them properly.

Then, use a good U-lock properly (leave minimum amount of space for someone to jam a jack in, difficult to cut) and a good quality chain if you're at home (so you have 2 tools). Make sure to grab the wheels (rim is sufficient) and the frame.

Also, make sure to lock to something that is safe to lock to (people have cut down small trees to steal bikes, or lifted something chained to a post over a post; or some things aren't as safe as they seem to some people, e.g. street signs which are often easily removable). The light post may not be a good idea; depending on the city, the police may cut the locks and impound the bike.

In spite of all this, there is a decent chance that a bike will get stolen in a tougher city; having a cheaper bike outside as a beater and taking out a nicer bike periodically (stored in your apartment) can help.

Alternatively, you can carry your bike into your apartment. It's inconvenient but its probably the safest option you have. Note that none of the above options prevent vandalism of the bike (as pointed out by Michael in the comments), which may or may not be of concern in your city.

I successfully keep a cheap old bike in a theft-prone area.

I'm on my second in 4 years because the first deteriorated, not because it was stolen. I use a good D-lock (it cost about as much as the bike, that is £/$/€30-50) through both chainstays to a bike rack. This secures the back wheel as well as the frame. The front wheel has a cheap cable lock through it, and the frame, to the rack. Both wheels use old-fashioned nuts rather than quick-release skewers.

I haven't had problems with the saddle being taken; again it's a nut rather than a QR. Accessories (pannier rack, bottle cage, lights) are attached using anti-tamper torx screws, though this didn't stop half my front light being stolen. The back light has been damaged (vandalism?) more than once, but is securely fastened to the pannier rack. I try to run with everything fixed to the bike as whatever I take off I have to carry on a longer ride (my commute is bike-train-bike with this only used for the 2nd ride).

The bike is also security-marked and has a big sticker saying so. The local police do this for free every few months otherwise it's quite pricey. One of the biggest deterrents though is that it's locked up near more expensive bikes (at the station), but at least as well as them.

I would second mattnz suggestion. Try a 20" folder, I have commuted on one for several years, and it was fine.

They are quite small folded or open. Easy to get up stairs and much easier to hang up in your appt compared to full sized bikes.

Many other advantages for the urbanite: easily goes on buses, cabs, metro, and easy to scab a ride with friends part-way on any journey.

The disadvantages are just the imaginary stuff that moaning myrtles always come up with.

I used to apply the rule that any lock you buy for a bike should be 10% of the value. But this theory has failed me a couple of times - with old bikes worth ~$100. People will steal any bike that looks easy enough.

D-locks are far better than cable locks - it's cable locks that have failed me twice. I've never had a bike with a d-lock stolen. I've had it that people have tried to put a crowbar through the d-lock and twist it to break it, but it just ruined the d-lock meaning I couldn't get the d-lock off but the bike was still safe. The d-lock was permanently full of scars where people had tried to cut it off. The kind of d-lock I bought was an Abus mid-range for ~$40.

Also fairly common was just to leave the heavy d-lock attached to where ever you leave the bike at night. Then if you're cycling around have a cable lock to leave the bike for a short while.

Buy it second hand for half or a quarter of shop price. If you know where to look, and try before you buy, you should be able to find good quality even still, especially if you know how to do easy maintenance stuff yourself (you can bargain on a second hand with worn out tires or brakes, and if that it's only problems then go for it).

If your commute is short, like five min, you don't need top quality.

Buy a good lock. Read tests on locks on the interweb, maybe https://thewirecutter.com/reviews/best-bike-lock/ Consider two locks (although that might scream "expensive bike")

Carry the front wheel with you after locking. Easy to remove/attach without tools on many bikes.

Paint your bike ugly/"unstealable" - choose a color you think people will find unattractive. Many if not most thieves steal to sell. Make it look much shabbier than it is: Tape things that don't really need it. Don't wash parts that don't really need it. Empty the air of a tire if you don't mind spending the extra time pumping the next day.

If you have a choice, park it near homes/windows, thieves first go where they can work unseen. But still, don't park it alone near streets with many walking or driving by who can see it.

Write "GPS tracking" on it.

In essence, think about how a thief thinks to avoid them. Which bikes get stolen, which don't. If posssible, don't buy the kind of bikes which are most popular and easiest to sell second hand in your city/country.

Thieves specialize in different types of locks, at least that is what the local police is telling. Having two different types of locks on your bike will counteract this specialization and will make it much harder.

Also, when I park my bike outside I always put it next to other bikes, if possible behind them, giving a potential thief more choice.

Store a decoy.

Lock up another cheap bike not far from your bike with a less secure, but not trivial, locking mechanism. If thieves are present in your area, they will go for the decoy first. If that bike gets stolen then take that as a warning and don't leave your real daily driver outside in that location anymore.

Of course, this won't do much for vandals.

Insure it against theft.

When I bought my touring bicycle in 2009, I was offered bicycle theft insurance. I was living in a very low risk area, so I declined, but if I had been living in circumstances like you describe, I would likely have taken the insurance. Read the policy carefully to see if they permit storing your bicycle outside overnight and make sure you use locks that are approved by the insurance policy.

As for locking your bike outside, a lot of useful answers already. Get several good locks. Since I moved from a low- to a high-risk area, I've been using the Abus Granit Power 58 along with a heavy chain lock and a frame lock, so my bicycle is triply locked with three different types of lock. It's a good bike but doesn't look like a typical expensive bike around here, as it's not for racing or mountain biking. It doesn't matter if you can see your bicycle from your apartment; you won't be permanently watching your bike and a competent bike thief can steal your bike in minutes. If you find a more suitable spot to lock it within a couple minutes walk, lock it there instead. As a bonus, when you are leaving your bike for a little while in a very low risk area, you can leave the heavy U-lock and chain lock at home and you'll still have the frame lock.

Here is a suggestion on how to get your bike up the stairway. I'm not sure how popular this technique is, but I have found that it is a lot easier to carry your bike by following these steps:

• Have the saddle up high at the efficient pedaling position (MTB riders might have it too low for this)


• Stand by your bike as you'd be "pushing" it around


• Turn around 180 degrees


• Grap the lowest point of the frame, between the front gear and the front tire (the front tire now being behind you)


• Put the saddle on top of your shoulder


• Stand up


• Walk ;)

Basically you are just dealing with the rigid rear end and the bike's handlebar and front tire will follow. This is especially easy when walking on a difficult terrain or up the stairs, but when walking down the stairs you have to pay a bit attention on having the front wheel high enough so that it won't hit the stairs behind you.

The saddle will put most of the weight of the bike on your shoulder, so your single arm just needs to hold it steady and the 2nd hand is left free from this exercise. Depending on the bike's weight and geometry you can even do this hands-free.

Don't select the most secure location available if storage is for the long term. That makes your bike an easy vandalism target because it's isolated. I once stored my second cheap bike into a traffic sign in an area where nobody stored bikes. It was targeted by vandalism.

Instead, choose a location where there are plenty of bikes outside and just leave your bike as one among the many. This is the solution I chose for my third cheap bike after the second cheap bike was targeted by vandalism. The third cheap bike did not experience any vandalism.

The truth is, if there are 10-20 other bikes around your bike, you don't even need to have a fixed object you can lock your bike to. Just put the lock to your frame so that it prevents the wheel from rotating. If you absolutely want to lock your bike to a fixed object, try to find a long cable lock, use a U-lock to lock the spokes of your rear wheel and use the cable lock to lock your frame to a fixed object. If the cable lock is long enough, you can in some cases both have your bike as one among the many and also have a fixed object to lock your bike to.

Why not just hoist it up to your balcony or window along the outside of the building ? Or rent a parking space elsewhere ?

In you car. You will need some quick-release front wheel with a quick-release front brake (I have hydraulic rim brakes from Magura, they are excellent brakes and very quick to remove and re-attach). Unless you own a van, in which case you can possibly store the bike as it is.

That would possibly not an option if you live in an area which is populated by drug addicts. These will happily break into any car (causing $1000s of damage) to steal a $100 item which they can sell for $10 to get their next shot). or in areas which see frequent bike races - there are teams of thieves who will go to such races to steal pro racing bikes from trucks, vans and even guarded parc fermés, literally leaving with a truckload of bikes.

The usual professional bike thieves, however, will be rather specialized on stealing bikes the "normal way": stealing single bikes by breaking the locks (cheap locks go in less than 10 seconds, expensive locks in 15 seconds or so) or multiple bikes by loading complete bicycle parking racks into a truck. They are less likely to break into a car. You might, however, consider to cover your bike under a blanket if it's really expensive (or even just expensive looking).

If you don't own a car already, buying one just for bike storage might be a bit pricey. If your rent includes free parking on private ground, you can buy just any crappy car and park it there (other tenants might of course complain about that crappy car that devaluates their upscale neighborhood...yes had this once, and later I found out that one neighbor actually hired someone to "remove" (steal) this eyesore). On a public road, you will possibly have costs for car insurance, license plates, taxes, vehicle inspection, etc. And you might need to move your car once a month so it doesn't look abandoned. Yes, people actually do this, especially in areas where the rent is expensive and parking is free (also near beaches for their surfboards...).
