Taking bikes on trains and metro, and avoiding theft

Key rules

• Operator rules: Bike rules depend on the operator, line and time, so check your exact journey before you travel.
• Folding bikes: A folded bike is often easier to take aboard, but confirm it is allowed on your service.
• Locking: Lock the frame and a wheel to a fixed rack with a strong U-lock.
• Proof of ownership: Keep the serial number and photos of your bike in case you need to report a theft.

Bike rules on Renfe trains and in the Madrid and Barcelona metros change, so confirm the current terms with the operator before you travel.

Check the operator's bike rules before you travel

Bike rules differ by operator, line, train type and time of day. Check the rules for your exact journey on the operator's website or at the station before you go. This page does not give operator-specific terms, so do not assume your bike is allowed.

Trains and regional services

• Ask the operator, by website or at the ticket desk, whether bikes are allowed on your Cercanías or regional train, and whether you need a reservation or a ticket for the bike.
• Expect limited space. Peak commuter hours are the most likely time to be refused.
• Board where the bike symbol is shown on the train, and keep the bike out of doorways and aisles.

Metro in Madrid and Barcelona

Each city's metro sets its own bike rules, including hours and which lines allow bikes. Look at the metro operator's site for your city, or ask staff at the station entrance, before you carry a bike down.

Folding bikes

Folding bikes are often easier to take on transit than full-size bikes, especially when folded and carried like luggage. Do not count on this. Check with the operator that a folded bike is allowed on your service.

Reduce theft risk

• Use a strong lock, ideally a hardened U-lock. A thin cable alone is easy to cut.
• Lock the frame and a wheel to a fixed rack or post that cannot be lifted off or cut through.
• Park in busy, well-lit places. Avoid leaving the bike outside overnight in the street if you can bring it indoors.
• Take lights, the saddle and any removable parts with you, or lock them too.
• Note the frame serial number and take photos of your bike. They help if you report a theft to the police.
• Ask your town hall about secure bike parking and any bike registry in your city.
• Check whether your home insurance covers bike theft.
