Fifteen new stations and 100 new bikes are also being introduced
Dublin City Council has announced that Just Eat will become the new commercial partner of Dublin Bikes in a three-year deal.
The 'Just Eat dublinbikes', along with their new look, were unveiled at Merrion Square in the city centre.
The bikes will be visible on the streets of the capital from the end of August.
Docking station screens, service vehicles and staff uniforms will also be re-branded.
As part of the changes, there will be 15 new stations and 100 new bikes rolled out later on this year.
Dublin city has had the scheme in place since 2009 - with almost 20 million journeys taken so far.
The scheme has also attracted 66,883 members.
Owen Keegan, chief executive of Dublin City Council, said: "It is vital for Dublin city that the public have access to viable and sustainable modes of transport.
"Dublin Bikes has played a huge part in the accelerated growth of cycling in Dublin and it is now rightly seen as integral to the public transport network."
