Cyclists own their bikes for, on average, 23 months before they are stolen, according to a leading insurer.
One in five bike owners have their new rides stolen within six months, and a third of those whose bikes are pinched do not report the thefts to police.
Research undertaken over the summer by LV= Home Insurance shows that one in five cyclists is a victim of bike theft, and although most expect to own their bikes for ten years, in fact they only get to keep them for two years before they are taken.
Official figures show that bike theft rose by 7% last year, but this may not show the true scale of the problem, given that a third (30 per cent) of victims don’t bother to report the crime to the police.
This is because nearly half (49 per cent) don’t feel it is worth reporting and a quarter (24 per cent) simply don’t think the police will be interested.
Although official crime figures show 114,000 bicycles were stolen in 20113, the actual figure is probably much higher due to so many thefts going unreported.
Home is not the safest place for a bike, as three in ten of those who have had a bike stolen say it was taken from their shed or garage and nearly a fifth say it was stolen from their driveway.
This seems to be borne out in Bristol, where there are fears that a gang is targeting mountain bikers, following riders of high end bikes home from local ride spots and then returning to steal their bikes later.
Over the years we have reported on a number of cases in which professional and semi professional riders in the Bristol and surrounding areas have had their bikes stolen - with the thieves usually targeting only the most valuable items.
London is the worst area for bike theft, with 28 per cent of cyclists having had a bike taken. But various police forces around the country deal with bike theft differently.
We reported how thirty people have been charged and more than £10,000 of property has been recovered in an innovative operation to target bicycle thieves in Aberdeen.
Operation Inchbrae was not just about enforcement, it was a multifaceted attack on bicycle theft.
"We analysed previous bike thefts in the city, looking for crime patterns and trends," said Inspector Thom. "Similarly, we looked at the profile of criminals caught or suspected of stealing bikes and we targeted them.
"Learning from this analysis, we helped raise awareness of bike thefts in Aberdeen by circulating regular information bulletins regarding crime hotspots, recently stolen bikes and crime prevention advice, through local bike shops and cycling clubs, to ensure that we have many more 'eyes and ears' in our cycling community and among residents.
"During the operation we investigated all bike thefts, followed all leads and proactively stopped and checked cyclists, particularly in respect of lighting or road traffic offences, allowing us to check over their bikes."
In Avon and Somerset, police released a video of an officer who played the role of a thief who was able to 'steal' a bike several times in broad daylight without anyone alerting the police - and urged the public to call 999 if they saw bike theft.
In this 2011 video from the London Cycling Campaign as part of its new Beat the Thief initiative, Barry Mason (who has sadly passed away) talks us round the locking methods used on real bikes by real cyclists on some sheffield stands somewhere in London:
We're strong believers in always filling your shackle but we're always looking for new ways to help beat bike thieves so if you've got any bike security tips you'd like to share with the crowd let's hear them!
After an unpromising start, having to be bribed by her parents to learn to ride without stabilisers, Sarah became rather keener on cycling in her university years, and was eventually persuaded to upgrade to proper road cycling by the prospect of a shiny red Italian bike, which she promptly destroyed by trapping a pair of knickers in the rear derailleur. Sarah writes about about cycling every weekend on road.cc.
