While bike riding might be daunting to some, it is undoubtedly one of the best ways to see a city. In 2015, Seoul joined the other 1000 cities around the world offering the bike-sharing system. Seoul Bike (or Ddareungi 따릉이), the Seoul bike rental system, now has over 800 stations all across Seoul.

There are two main types of bikes called LCD and QR. LCD is the original type of bike in the Seoul bike rental system, while QR bikes were added more recently (2020) to simplify the renting and returning system. While Seoul Bike has a website available in English where you can purchase tickets/vouchers to use the bike renting service, we recommend getting the Seoul Bike mobile app (Android / iOS ) for an overall smoother renting process.

Planning your trip with Seoul Bike

  1. Locate bike rental stations for both renting and returning. (Find bike stations at Seoul Bike or in the Seoul Bike mobile app)
  2. Make sure the station you have chosen has enough bikes available. The number inside the circles representing the stations is the number of available bikes, and it is updated in real time.
  3. Note that there are both green stations (LCD, QR bikes) and yellow stations (QR bikes only). Pay attention to this aspect and check in advance, as LCD bikes can only be rented from and returned at green stations. Depending on your destination and the stations around, make sure you rent the right type of bike.

Renting The Bike

Through the Website (LCD bikes only)

To rent a bike, you can register and pay anywhere via mobile or PC. Once you get your code, it is valid for 24 hours. If the code is not used within 24 hours, your money will be refunded. The pickup time and location is not required. The rental period time does not start until the bike is removed from the dock.

! You can only return LCD bikes at the green rental stations on the map.

  3. Make sure the lock is properly secured as there is a ₩200 additional fee per 5 minutes after original rental period.
