How to Rent a Seoul Bike (Ttareungyi) as a Tourist: Passes and Steps

Short answer: Yes, tourists can rent Seoul's public bikes. The system is officially called Seoul Bike, and locals call it Ttareungyi (따릉이). Download the official Seoul Bike app and choose the foreigner or non-member option. Buy a short pass with a Visa or Mastercard, then unlock a green-and-white bike at any docking station. Passes are cheap: a one-hour pass has long cost around ₩1,000, and there is also a one-day pass. Return the bike to any station and wait for the app to confirm the return. Fares and sign-up steps change from time to time, so check the app before you ride.

This guide covers how passes work, how to sign up without a Korean bank account, how to unlock and return a bike, and the best easy routes for a first ride. A note on "Sky Bike": the name usually means a rail-bike or sky-cycle ride at an amusement park or tourist park. That is a separate paid attraction, not part of the city bike system. This guide is about the city bikes you see at almost every subway exit.

What is Ttareungyi?

Ttareungyi is Seoul's public bike-sharing system, run by the Seoul Metropolitan Government. There are thousands of bikes and docking stations across the city. Most stations are near subway exits, along the Han River parks or beside large apartment complexes. The bikes are simple city bikes with a basket, a bell, a front light and a few gears. Many bikes now unlock by scanning a QR code with the app.

The name comes from ttareung, the Korean sound of a bicycle bell. That is why many locals smile when they say it.

Which pass should a tourist buy?

Short passes (best for most visitors)

1-hour pass: Each ride can last up to one hour. This is enough to ride along the Han River from one park to the next.
2-hour pass: Each ride can last up to two hours. Good if you want to ride a longer stretch without stopping.
One-day pass: Take as many rides as you like that day, as long as you dock the bike before each ride's time limit runs out. This suits a full day of hopping between neighbourhoods.

Longer passes

There are also 7-day, 30-day and longer passes. Some of these may need a Korean account or local verification. If you are in Seoul for only a few days, the short passes are simpler.

Important: Each ride has a time limit. If you keep the bike past it, extra charges are added. When you are close to the limit, return the bike to any station and rent it again.

How to rent a bike, step by step

1. Get the app and mobile data

Download the official Seoul Bike (서울자전거 따릉이) app from the App Store or Google Play before your trip. You need mobile data or Wi-Fi to buy a pass and unlock a bike, so a working SIM or eSIM makes things much easier.

2. Choose the foreigner or non-member option

Switch the app to English and look for the option for foreigners or non-members. The sign-up steps have changed several times over the years, and the English version can be a little rough. Visitors report that an email address is usually enough, but sometimes a phone number is also asked for. If one path fails, try the other sign-up option in the app.

3. Pay with an international card

Visa and Mastercard credit cards usually work. Some travellers report errors with certain cards, so it helps to have a second card. Some guides also mention a temporary hold on your card. Read the payment screen so you know what is being charged.

4. Unlock the bike

Find a station on the app map. It shows how many bikes each station has.
Choose a bike. Check the tyres, brakes and seat height before you start.
Unlock it the way the app tells you: scan the QR code, or enter a rental code on the bike's lock.
Take a screenshot of any rental code the app gives you, in case the app closes.

5. Return the bike

Ride to any Ttareungyi station. You do not have to return the bike where you started.
Push the bike firmly into an empty dock, or close the lock as the app tells you.
Wait until the app or the lock shows the return is complete. Do not walk away before you see that. A bike that is not properly returned still counts as your rental.

Easy first routes

Han River parks

The flat bike paths along the Han River are the classic Ttareungyi ride. Yeouido, Banpo and Ttukseom Hangang Parks all have stations nearby. An easy evening ride at Banpo pairs well with the Moonlight Rainbow Fountain, which we cover in our guide to free night views in Seoul.

Seoul Forest and Seongsu

Seoul Forest has wide paths and stations near its entrances. Ride through the park, then dock the bike and walk into the cafe streets of Seongsu. Our Seoul Forest and Seongsu half-day walk shows what to see once you are off the bike.

Stream-side paths

Several streams that flow into the Han River, such as Jungnangcheon and Anyangcheon, have long bike paths beside them. They are quieter than the main river paths and show you ordinary Seoul neighbourhoods.

"Ride slowly by the river at golden hour. The bell is for saying hello, not for hurrying people." — Haru, POPORO CITY

Safety and rules

Korean law asks cyclists to wear a helmet. Many riders go without, and only some stations lend helmets. Bring your own if you plan long rides.
Use bike paths where you can. On crowded pavements, get off and walk the bike.
Never ride after drinking. Cycling under the influence is illegal in Korea.
Turn on the light after dark. Most bikes have a built-in front light.
Han River paths get busy on weekend evenings, and road cyclists ride fast there. Keep to the right and look behind you before you stop.

Quick tips

Install the Seoul Bike app and try the sign-up before you arrive.
Start with a short pass. Only buy a longer one if you really ride a lot.
Dock and rent again before your ride time runs out to avoid extra fees.
Screenshot your rental code.
Wait for the return confirmation before you leave the station.
Check current fares and rules in the app, as they can change.

FAQ

Do I need a Korean phone number to rent a Seoul bike?

Usually not for a short pass. Visitors normally sign up with an email address through the foreigner or non-member option. The app changes from time to time, so if it asks for a phone number, try the other sign-up option or ask your hotel for help.

Can I pay for Ttareungyi with a T-money card?

Do not count on it. Most tourists pay in the app with an international credit card. Check the app for current payment options.

How long can I keep one bike?

Each ride is limited by your pass, usually to one or two hours. If your pass is still valid, you can return the bike and rent again straight away.

What if there are no empty docks at a station?

Check the app map for the nearest station with free docks. In busy areas, stations are often only a few hundred metres apart.

Is cycling in Seoul safe for beginners?

The Han River and stream-side paths are flat and away from cars, so they are a good place to start. Avoid busy roads until you feel confident.
