The capital featured as highly as ninth in the first edition of the index, but has experienced a gradual slide in recent years.
Danish company Copenhagenize has released its bi-annual index of the world's top 20 bicycle-friendly cities - and for the first time, Dublin does not feature on the list - writes dublinlive.ie.
The company, which specialises in advising cities and governments in working towards becoming more cyclist-friendly, has released the so-called Copenhagenize Index every two years since 2011.
Among the factors considered for inclusion are bicycle culture, perception of safety, gender split, bicycle facilities, social acceptance, traffic calming, and urban planning.
But while Dublin finished as high as ninth in the index in 2011, it experienced a slide in the last two editions - when it finished 11th and 15th - before dropping out of the index entirely this time.
Commenting on Dublin's exit from this year's list, Copenhagenize said: "After many years of progress, the city has stagnated and, to be honest, disappointed."
Copenhagen topped the index for the second time running, followed by Utrecht and Amsterdam in the Netherlands, Strasbourg in France, and Malmo in Sweden.
