Bike Week has started and there are events in every county and every day, up to and including 17 May.
The week runs every year with the aim of supporting those who cycle while also encouraging those who have yet to take it up.
It is coordinated by the National Transport Authority and each local authority runs an event in their area.
Dublin City Council held its flagship event, Pedal Power, at Eamonn Ceannt Park in Crumlin.
There were BMX stunt riders from Fire Ride, free bike repairs by the Bike Hub and a free school on how to cycle safely for children.
Dublin City Council's Bicycle Mayor Donna Cooney led a colourful bike parade to the park.
The Green Party councillor said there will be a range of events across Dublin city over the next week.
"There's everything from cúpla focail on your bicycle on Friday night, there's dawn rides, there's biosphere bikes and birds, there's a swim and a cycle, and there's something for everybody," she said.
Ms Cooney said some activities must be booked as "they need to know the numbers", but she added "they're all free".
"But you just book them on Eventbrite. They're all up on the website, and they're all supported by the NTA," she said.
"You can get all the ones in Dublin on the Dublin City Council website and at the other local authority websites as well," she added.

At Pedal Power, the sponsors of Dublin Bike set up a bike on a treadmill for a challenge to see who could cycle the fastest down a virtual O’Connell Street.
Jimmy Lally was one of those at the event who tried the challenge.
The 82-year-old is no stranger to competitive cycling, he joined a club at 15 years old and raced for 60 seasons.
He still cycles every day, describing it as "like a drug".
Mr Lally said: "I can't give it up. I do something every day on the bike – actually every day.
"If I don't do a little bit in the garage (on a static bike), I go out."
He said he cycles 100km or 120km "regularly" on "Tuesday, Thursday, Saturday in particular".
Mr Lally said he would usually do around 300km a week, adding that while how you age can often be down to luck and genetics, he thinks his regime has helped to him to stay in good health.
At the other end of the age scale many youngsters were taking advantage of a free cycling school on the track.
Alec Darragh of Cycling Ireland said they give free training at Eamonn Ceannt Park.
He said: "We run an open session for schools, any kids at all.
"They come up here, we provide them with bikes and helmets, if they don’t have their own.
"We encourage them and we give them some basic instruction on how to cycle safely."
He added that with the roads so busy, children need to have safety skills.
"When I started cycling it was safe to learn on the roads, nowadays it’s too dangerous on the roads," he added.
Cycling infrastructure in Dublin has improved in recent years but Daniel Alexander, one of the children enjoying time on the track at Pedal Power, told RTÉ News there can still be obstacles.
"They’re (the bike lanes) perfect, just people park their cars in the middle of the bike lane, so weird," he said.
Details of the Bike Week events are available on the National Transport Authority website and through local authorities.
