The capital is most badly affected place with four out of the top ten highest risk areas found in London.

The average cost of replacing a stolen bicycle is higher than some may expect, at £337. With the frequency of bicycle thefts in this country and the high cost of replacing a stolen bicycle, insurance is something all cyclists should consider.

If your house is burgled, your contents insurance may cover your bicycle, but there may be snags. Some policies will only cover up to a certain price, so if you have a particularly expensive bicycle you should consider bicycle insurance.

Also if your bike is stolen outside of your home, it is unlikely that your contents insurance will cover your bike. Considering that 95 per cent of bicycle thefts are made outside of the home, individual bike insurance is a good idea.

Halifax Insurance have found that even if you lock up your bike when you are out and about, this may not be enough. According to their data, 86 per cent of all stolen bicycles were locked up when they were stolen.

Halifax head of underwriting David Rochester says “We have been looking into the frequency of bike theft for some years now and still we see no sign of a decrease in this crime. We encourage all who experience bike theft to report it to the police, otherwise they could miss the opportunity to make a claim.”

Halifax have a few tips to minimise your chances of having your bicycle stolen. They recommend using bicycle racks when locking your bike up and where possible locking your bike up in well lit areas.

They warn that when keeping your bike at your property or when it is not in use, to keep it locked inside either your house or an outside building. Make sure that wherever you store your bicycle, the door is always kept locked.

Halifax recommend using hardened steel U-type locks as simple cable locks are easily cut within minutes.  Other security devices such as anti-pry devices which cover the gap between the bike and the object it is secured to, preventing a thief from inserting a tool in the void and prying or twisting the bike free.

To protect you in the event that your bike is stolen, it is a good idea to register your bike at one of the bike ownership agencies, making it harder for the thief to sell.

Using an ultraviolet marker pen to write your postcode on the frame will help police to identify your bike if it is stolen, and return it to you.

If you write down the name model and serial number of the bicycle, you will be armed with all the details which the police need for their attempt to find your bike.

Taking photographs of your bike and keeping a note of extras will ensure that you can prove what kind of bike was stolen and will get an accurate payout from your insurance company.

OnGuard Bulldog STD 5010LM Bicycle U-Lock

Bicycle theft is a growing crime throughout the United States, and it doesn’t matter where you live. Bicycles are relatively easy to steal and easy to sell or get rid of. They’re an easy target for dedicated criminals, opportunists, and bored teenagers. Unless you never intend to leave your bike untended, you should invest in some sort of locking system. Even if you’re just leaving it outside a convenience store for a couple minutes so you can go inside real quick, that’s all the time a thief needs to make off with your ride. Don’t think that thieves won’t steal a cheap bike, either. They’ll take whatever they can get their hands on, whether it’s a rusted old girl’s bike with faded streams dangling from the handlebar grips and a torn-up banana seat or a sleek high-dollar professional mountain bike with full front and rear suspension.

There are basically two options when it comes to locking systems for bikes. The most popular is the chain or cable lock with either a separate padlock or combination lock or with the lock integrated into the chain or cable. If this is the type of lock you’re looking into, make sure that it’s long enough to wrap around both wheels and the frame. With this style of locking system, the best choice is a chain that’s as thick as you can comfortably carry.

If you’d prefer a cable lock, again, make sure you purchase the thickest one possible. The thicker the chain or cable, the more of a deterrent it’ll be for thieves and scoundrels. The downside, of course, is weight. Cables tend to be lighter than chains, but they also tend to be easier to cut. You have to consider the importance of weight relative to your bicycling activity.

An avid racer is extremely concerned with weight, but such a competitor isn’t going to be leaving his/her bike just lying around, either. In all likelihood, weight is not a serious issue to you. One advantage chain/cable locks have over other varieties of locks is their ability to encompass oddly shaped shaped objects such as trees, bushes, etc.

The other popular bicycle locking system is the U-lock. As the name implies, such locks have a big bend in them and are essentially big padlocks. Some are only big enough to go around the back wheel and the bike rack. Others are big enough to go around the frame as well. These sorts of locks are nice because they’re quick to employ and come with clips to hook onto the bike frame without scratching it.

Whatever kind of bike riding you intend to do, unless it’s solely competitive racing, you should invest in a good bike lock. You should get the heaviest one you can. An important feature to look for is some sort of guarantee by the manufacturer. Good locks come with assurances that if used correctly, and your bike is stolen, the manufacturer will reimburse you for the cost of your bike.

This crime happens everywhere. Even though New York has the most number of bikes stolen every town and small city will have its bike stealers. There are all kinds of bikes that can be stolen from a thousand dollar race machine to a junky bike just needed by someone to make it home. Some thieves will steal the bikes to sell them and get money for your bike. Maybe a thief just needs a ride to get somewhere and he needs your bike and you are not watching it at the time. If you have a cheap lock on the bike the thief could pick it or clip it.

If you have that cheap lock and it has been working for you your day may soon come. You need to buy a lock that is going to make sure that your bike is safe. You can buy any kind of lock. You will need something that will have some sort of key not a combination as someone with a good bit of luck could just say, “oh lets try it just for a second”, and might pick your lock and steal your ride.

Chain locks are the other really good type of lock. They can be very heavy and a thieve wont think about clipping the chain it will probably make a lot of noise and also probably wont be worth going to jail or getting beat up over. The bigger locks that are out there on the market will help you with securing your bike though and companies like bell will make a good lock for you. If you buy the right bike lock then you will be able to ride anywhere you want and be able to lock it up anywhere you want without it getting stolen. That’s the last thing you would want to happen as you ride up to the store for a soda is to walk out and see your bike gone when you could have just bought a lock for your bike. So do the right thing for your ride and buy the lock so it doesn’t get jacked like all your other bikes did.

One important thing to consider when choosing a bike lock is who will most likely steal your bike. On a busy university campus, for example, thefts are often crimes of convenience when someone spots a bike that hasn’t been locked at all. However, if you ride your bike around an urban centre for commuting, people might have specialised equipment such as crowbars, lock-picks and hacksaws that are no match for weaker locks. Leaving your bike in the same public place for hours at a time, as opposed to a few minutes while you rent a DVD, gives someone even more time to take advantage of your lock’s particular weakness.

You’ll want the best possible bike lock you can afford, since its cost is always less than that of replacing a stolen bicycle. Most people recommend spending about 10% of the value of your bike on its lock. If your bicycle is very precious or expensive, try a combination of several locks when leaving your bike in an unfamiliar area or for an extended period of time.

Materials

Buy a lock or chain of tool-hardened steel. This means that cutting, sawing and drilling tools will be meeting metal of the same hardness, and will not penetrate it as they would ordinary steels. Cheap locks use a brittle steel that can be broken by a car jack. Look for a flexible, shatterproof steel which will yield, rather than break, under stress.

* Consider a U-lock. These are the most popular. However, not all U-locks are created equal. Be sure to read the guarantee that comes with the lock. Also, buy the smallest possible U-lock for your needs – this will allow less room for a thief to some leverage for his or her crowbar or other tools.

* Consider a cable lock. These are the easiest for a thief to cut but are also the most flexible and inexpensive.

* Consider a motorcycle lock. These are very sturdy chain-link-type locks that are nearly impossible to cut through. However, they are extremely heavy.

* Consider a key lock. Key locks are generally harder to break than combination locks.

* O-Locks offer the best protection for your bike. A few manufacturers are marketing them; Bike Club and Masterlock are two that come to mind, but not all bicycle shops carry them. Ask around. The adjustability makes them great for snugly securing the frame and a front wheel to a bike rack. This helps prevent thieves from getting a prying device into the lock. Their locking mechanisms are also difficult to pick.

The bike lock mechanism is composed of two different parts: a structure that fastens your bike to itself or to a stationary railing and the lock itself, both of which have strengths and weaknesses. Some bike locks use combinations, like lockers. While combinations seem secure because they aren’t easy to guess, these kinds of locks are usually strapped to a thin metal chain that is easy to clip apart with bolt cutters. Then again, you don’t have to worry about losing a key if you are prone to forgetfulness, and they are lightweight enough to carry everywhere. Combination locks will work as a visual deterrent against people looking for an easy theft.

Warranty

Good locks will guarantee your bike against theft up to a specified value. As home insurance policies generally does not apply to stolen bikes worth more than INR 23000 or so, this is an important feature. Ensure you have adequate bike insurance.

For many people, weight is an important consideration when selecting a bike lock. Whether you’re training in mountain biking, cross-country marathons, or just visiting a friend, the last thing you want is a twenty-pound weight strapped around your frame slowing you down. There isn’t a precise correlation between weight and strength, however. A special steel, called tool-hardened steel, will at least be as strong as many saws and cutters without being overly heavy.

Some manufacturers offer a warranty along with their lock that may partially reimburse you should your bike disappear. Of course, nothing is absolute. Recently, it came to the attention of concerned bike riders that some types of very secure locks can in fact be opened with the plastic shaft from an ordinary pen. Keep in mind that while every bike lock has its weakness, there are many issues to consider when buying the right one for your bike.
