Types of offenders
Although many bicycle thefts occur by offenders looking for financial gain, other offenders can be categorized into the following categories regarding their motivation.
- Joyriders: Joyriders steal bikes for the sole purpose of riding the stolen bike for entertainment and will generally abandon the bike after using it. Most of these offenders are male and under the age of 16.
- Acquisitive: These thieves steal bicycles for financial gain and usually trade them for cash or goods.
Those looking to steal bikes can use a variety of different methods in order to do so.
- Lifting: If the bike is locked to an insecure structure such as a small sign or tree, the thief is able to lift the bike along with its lock off of the structure.
- Cutting: A thief may use a bolt cutter, hacksaw, or angle grinder to cut through the bicycle lock.
- Picking: A thief may pick a lock that has a keyhole.
- Sucker pole: A sucker pole is a pole that appears to be safe to lock a bike to, but can easily be dismantled by bicycle thieves. It may be a sign, fence, or bike rack. In Chicago, 252 bicycles were stolen in this manner in 2012.
Bicycle theft is a common crime committed in areas with high population as well as on college campuses. According to the Police Department at the University of Colorado, Boulder, it was found that most bicycle thefts involved bikes being unlocked, improperly locked, or locked with devices such as a lightweight cable or low-quality U-lock devices.
One can prevent bicycle theft by avoiding using bicycles with quick release wheels, as these are easy for anyone to take off without the use of any tools. Furthermore, one should use a strong U-lock to secure their bike. One should only lock his or her bike to sturdy structures and should not leave the bike in one place for too long.
The way in which the bike is locked to the structure is also important. It is important that both a wheel and the frame of the bike are locked to a structure so that a thief cannot steal a wheel and leave the bike, or vice versa. A former London bike thief recommended small and stiff d-locks, as they are hardest to cut.
