More than 150 cyclists across Lancaster and Morecambe had their bikes security marked for free by police during January.
Bike Security Month was held after a rise in bicycle thefts in the area and the service was offered at police stations every weekend.
Lancashire Polie, in partnership with the county council, bought special kits to mark bikes with a permanent, unique reference number, making them easier to trace if they are stolen.
Officers are to continue to offer the service while the marking kits last, with the next event being held at Morecambe Library between 12pm and 3pm on Saturday, February 8. People interested can also email email@example.com
PC Gillian Syer, of Lancaster Police, said: “Bike Security Month was a great success, with over 150 bikes being marked.
“By registering their bikes, our residents have hopefully deterred thieves and, in the event of their bike being stolen, we will now have a much better chance of reuniting owners with their bikes, and I strongly encourage any bike owners who haven’t already to take up this opportunity to improve the security of their bikes.”
