In the second half of 2017 more than 446 bikes were stolen from the PO1 area, covering Portsmouth city centre while another 30 were stolen from the PO6 area around Cosham, according to theft reporting website stolen-bikes.co.uk.
However, there are a number of things we can do about this.
Here are our top tips to make sure your bikes stay where you left them.
Always lock your bicycle up – especially in a bike shed (where provided). It only takes seconds to steal an unsecured bike. Make sure it's locked in a well-lit public area where there are lots of people passing. Railway stations and public buildings often have designated areas with bicycle racks. Remember to read signs in the area you intend to park being sure not to park illegally.
Only use good quality D-locks. A poor quality lock at the lower end of the market can be easily cut through. It certainly pays to invest in the best quality lock you can afford. Always lock your bicycle to something immovable, an object a bicycle cannot be lifted over and cannot be broken, cut or removed, for example chain link fencing, grilles, gates or trees. Check the object is fastened to the ground. For maximum protection use two locks of different types (a D-lock and robust chain and padlock is ideal) Make sure you lock up both the bike's frame and wheels.
As many as half of all bicycles are stolen from their owner's home. Always lock your bike at home even when it is in your garage, flat or halls of residence. Make sure you keep your bicycle out of view of prying eyes if possible too.
If you own a decent bike, then it's probably a good idea to insure it. There are several ways you can do this including through your home contents insurance (don't forget to cover it for thefts away from home). More expensive bicycles may require specific insurance cover against theft and accidental damage. A range of companies offer urban cycling insurance including London Cycling Campaign.
