Dublin's oldest bike shop is to close down with the current owners citing the rising cost of doing business as one of the reasons.

The family-run Delaney's Bikes on the southside of the city first opened its doors more than a century ago.

The shop has been at the Harold's Cross bridge junction on the southside of the city since 1917.

Brian Delaney, who has been working alongside his brother Paul in the shop for the last four decades, said the shop has helped thousands of Dubliners with their bikes over the years.

The business was started by their great grandfather and has been passed down ever since.

''I don't think we ever thought it would last this long... being in the family and one generation took over from the next, but I don't think any of us realised we'd get to 105 years. Not much lasts that long these days, so we must have been doing something right,'' Brian said.

Save for the odd touch-up through the years, the red shop front has stayed the same. It's become a landmark, a familiar site for many on the busy road.

"My dad used to say when somebody was looking for directions, they would always be told, 'Coming up to Dublin? Come up down the canal to the red shop on the corner and then turn over the bridge and you go straight into town'. They'd reference here for a turning point,'' he said.

Down in the basement Paul is sifting through stock and old invoices dating back from the 1960s.

''I wish we could keep it going. But it's just not feasible in the current climate. So, we did our figures, added up what was coming in and what was going out. And we've decided to close the door," said Paul.

The brothers are close to retirement age, but the current cost of doing business sealed their fate.

"Everything I buy in has gone up nearly 60%. And then of course you've got your cost of living, your electricity ... they've all gone up," said Paul.

"We tackled it as best we could. We did longer opening hours, we cut our wages... It took a lot of time and a lot of thought and a lot of to and fro between me and my brother.

"And when we put pen to paper, talked to the accountant he said, 'Yeah, you're doing the right thing, lads. Close it down and open a new chapter somewhere else'."

This week loyal customers have been dropping in to say their goodbyes. The shop and the two floors above it are up for sale. The brothers will lock up for the last time at the end of the month.

"It probably won't hit me till I close the door and when I look back and say, 'Wow, we've just had 100 years'. Thinking about it now, it's getting to me. It will be tough, yeah, very much so. The end of an era,'' he added.
