Guide

Take your own bike abroad, or rent one there?

You've booked a week in Calpe, or Mallorca in April, or Girona, or Lanzarote in February. Most people start by looking up the airline's bike fee, wincing, and stopping there. But the fee isn't really the question. The question is whether to bring your own bike at all, when there's a shop at the other end with a wall of them.

What it costs to bring your own

Three numbers, and they're wildly different sizes. The fees below were checked against each airline's own pages on 27 July 2026 and are set out in full in our guide to flying with a bike box . Airlines move them, so check before you book.

• The airline fee, both ways. Ryanair is €60 each way when you book it — €120 return. Aer Lingus is €50 each way, so €100 return. Everyone remembers it's charged twice and then quotes themselves the one-way price anyway.
• The box. A hard bike box is €400 or more to buy, which for a single trip dwarfs the flying. Borrow one instead and it's the owner's daily rate plus a refundable deposit.
• The weight you go over by. Nobody budgets for this and it turns up at the bag drop with no way out. More on it below.

The daily rate that beats bringing your own

Rental prices vary far too much by country, season and bike to quote honestly here — a carbon road bike in Mallorca in April is not a hybrid in Lanzarote in November, and any number we printed would be wrong within a season. So look up the actual rate where you're going, then compare it against a fixed figure, because that's what bringing your own is.

If you already own a box, flying your bike costs the same whether you're away three days or three weeks. Divide it by the days and you get the rental rate you're competing with:

Read it as a break-even. If renting where you're going costs more per day than the figure in the table, bringing your own is cheaper. If it costs less, renting is. The pattern is blunt and it holds everywhere: the longer the trip, the more sense your own bike makes. For a long weekend you'd need to find rental under about €40 a day to be beaten; for a fortnight, almost any rental in Europe beats €9 a day, and the money argument for flying a bike quietly disappears.

If you don't own a box, add what it costs to get one to both sides of the comparison — €400 to buy, or a few days' hire from a neighbour. On a single trip, buying a box is usually the thing that settles the argument in renting's favour all by itself.

Where Irish cyclists actually go

The destinations that fill flights out of Dublin and Cork every spring — Calpe, Mallorca, Girona, Lanzarote, the Algarve — pull the answer in two directions at once, and it's worth seeing both.

The trip length argues for bringing your own. Nobody flies to Calpe for a day. These are week-long training camps and warm-weather blocks, and a week is where the table above starts favouring your own bike: you'd need to find rental under about €17 a day to beat a Ryanair return with a box you already have.

The rental scene argues against it. These places are cycling towns. The shops there exist for exactly this trade — current bikes, proper fitting on arrival, and someone to swap a stem or a cassette if the first one isn't right. The usual worry about renting, that you're gambling on whatever's in the back of a shop, is weakest precisely where Irish cyclists go. Prices vary enough by town and season that the only honest advice is to get a quote for your dates before you decide.

So the split tends to land like this: a spring training block where you'll ride your own numbers every day, bring it. A shorter trip, a social one, or a first visit where you'd rather not shepherd a box through Alicante airport, rent there.

The weight limit that catches people

Aer Lingus caps a bike at 23kg. That sounds generous until you weigh the box: a hard case is often 11–13kg empty, leaving ten or twelve kilos for everything inside. A road bike at 8kg fits with room to spare. A gravel bike with heavier wheels, plus shoes, a track pump and a toolkit, does not.

Ryanair allows 30kg but charges €13 for every kilo over. Five kilos over is €65 — more than the bike fee itself, and avoidable entirely by putting the packed box on the bathroom scales the night before. Cheapest ten minutes of the trip.

The part that isn't about money

For a lot of riders the arithmetic above is beside the point, and it's worth being honest about which way it cuts.

• Your bike fits you. Saddle height, bar reach, your pedals, gearing you know on a climb you don't. If the trip is a sportive or a target event, that's usually the whole argument, and no rental matches it.
• A rental is a known quantity too, though. Decent shops in cycling destinations keep current bikes, fit you on arrival, and swap anything that isn't right. You also aren't the one carrying a 20kg box through two airports.
• Flying a bike carries risk. Even packed well, it can arrive damaged, and it can arrive late — a bike that misses the connection costs you a riding day the rental never would.
• Time and hassle are real costs. An hour packing, an hour rebuilding, an oversized-baggage desk at both ends, and a box to store at the other end for the week.

So, which?

Bring your own for a week or more, for a training block or an event you care about, or when your bike is set up in a way a rental won't replicate. Rent there for a long weekend, a social trip, or anywhere the local rate undercuts the table above — and especially if the alternative is buying a €400 box for one week in Lanzarote.

And if you land on bringing it: you need a box for a fortnight, not forever. There's likely one twenty minutes away doing nothing, because that's what bike boxes do for the fifty weeks nobody's flying.
