Six bikes have been stolen in Harrogate town centre this week, bringing the total to 21 since last month.
North Yorkshire Police has increased its patrols in town and urged cyclists to take extra precautions to keep their bikes safe.
The thefts have taken place across all times of day and night and cycles of a value ranging from a few pounds to a few thousand pounds have been targeted.
Inspector Alex Langley, of Harrogate Town Centre Neighbourhood Policing Team, said: “The advice I would like to offer to cyclists is that parking your bike at the rear of your work premises may be the most convenient for you to get in and out of work – but is it the safest place for your bike?
“Often people feel that because they have bought a cycle lock that means their bike is secure and will not be stolen.
“Unfortunately, criminals have access to bolt croppers and wire cutters, and locking a bike to a fire escape in an isolated back street or private area only gives criminals more time and freedom to remove your lock and then make off unseen and unheard.
“If possible, always ensure your bike is secured inside a garage or shed, and do not risk leaving it unattended overnight.”
Cyclists have being asked to follow three safety measures:
1. Always lock your bike when it is unattended.
2. Ensure that you lock is fit for purpose and could not be simply snapped or pulled apart with minimal force.
3. Think about where you are parking your bike. Would a thief be happy spending a few minutes sawing or cutting your lock in this area? If the answer is ‘yes’ then maybe you need to move to a more public place.
Safer Harrogate has released a video with advice that can be viewed at https://www.youtube.com/watch?v=v6ZOE2yhzwo and has asked cyclists to consider having their cycles security marked to make them easier to recover if lost or stolen.
