The schemes currently operate in Belfast, Cork, Dublin, Galway and Limerick
There were nearly five million journeys on public bike schemes in Ireland last year.
The schemes are currently running across Belfast, Cork, Dublin, Galway and Limerick, and have a total of 91,850 subscribers.
The Dublin Bikes scheme accounts for a significant majority of journeys - with 4,355,437 trips taken in 2016.
According to statistics released today, the three regional city schemes in Cork, Galway and Limerick saw a total of 337,056 journeys in 2016.
An additional 211,358 journeys were made in Belfast.
Anne Graham, CEO of the National Transport Authority, said: “There is no question that the bike schemes which are today found in cities across the country are important local transport infrastructure assets. Once established, it can be easy to take the schemes for granted, but as today’s statistics show, the public is using Coca-Cola Zero Bikes for the trips they make every day.
"We look forward to collaborating with our partners to increase usage of the bikes in 2017, and further contribute to Ireland’s reputation as a hub for cycling and sustainable transportation internationally," she added.
Coca-Cola Ireland, which sponsors the schemes, said it is "something we are very proud to have supported”.
