More than 14,000 bicycles, worth in excess of €2m, have been stolen over the past two-and-a-half years.
The scale of bike thefts is revealed in figures compiled by the Garda Analysis Services, which show that of the 14,000 bikes stolen since January 2016, Dublin, Cork, Limerick and Galway are being targeted specifically.
These four cities account for 83% of the total number of thefts.
More than 6,000 bikes were stolen last year, a 7.5% increase year-on-year.
