Using Ddareungi in Seoul

Seoul’s public bike share is useful for short city hops, but it is not the same as having your own bike for a proper ride.

Quick Verdict

Useful for short hops.

Not a magic Seoul cycling solution.

What To Know First

Ddareungi is Seoul’s public bike share. It is good for short connections, casual rides, and getting from transit to a river or neighborhood path.

It is not the tool I would plan a full day ride around. Availability, station balance, bike condition, and time limits can all get in the way.

Family Pass

Seoul introduced a Family Pass in 2025 that allows children under 13 to use Ddareungi under parental supervision.

That makes family riding easier, but it does not remove the usual street reality: station access, helmets, traffic, and path crowding still matter.

Family Pass campaign (September 21–November 20, 2026)

Members riding with children under 13 can enter two events during this period. For the photo draw, buy and use Family Pass during the campaign, then submit your Ddareungi ID and a photo showing the child, helmet and bike through the operator’s participation form. Faces need not be visible. Take the photo with the bike stopped in a safe place; one entry per ID.

Family Pass use during the campaign also enters a separate usage challenge automatically, with prizes based on distance, riding days and a draw. Prizes are not guaranteed. Children must wear helmets and ride under adult supervision; the adult scans the bike’s QR code to rent it. Keep the ride within the child’s ability.

Helmet verification draw through November 27

App renters who complete the AI helmet check within five minutes of starting a rental are entered for one of 50 food-and-drink vouchers. The operator says the verification image is deleted immediately after the check.

This is an optional prize campaign. It does not change rental eligibility or helmet law. Stop somewhere safe before taking the verification photo.

Climate Card Note

Old Climate Card use has ended. Prepaid recharge ended August 31, prepaid use ended September 29, and postpaid use ended September 30.

Everyone’s Card (Climate Companion Pass) launched on September 1. Official notices still list its Ddareungi discount linkage as a later addition and do not confirm when it starts. See the dated transition update for the current status.

Redistribution Mileage

Seoul Facilities Corporation is running a Ddareungi redistribution mileage program from May 4 to November 30, 2026.

The basic idea is simple: take a bike from an oversupplied station or return it to an undersupplied station during weekday commute windows, then receive mileage for Ddareungi passes. The notice says commute windows are 07:00-09:00 and 17:00-19:00, weekdays only.

Useful if it fits your normal trip. Not worth turning your ride into a logistics shift.

Energy Donation Riding — Season 2 (September 7–October 16, 2026)

This is a separate Ddareungi campaign. Registration runs from August 31 through October 16. Signing up and recording a qualifying ride are separate steps, so riding during the time window without registering is not enough.

Qualifying rides run on weekdays from September 7 through October 16. The departure windows are:

  • 05:00-10:00 for the morning commute
  • 17:00-23:00 for the evening commute

Only two rides per day can qualify.

This is a donation campaign, not rider mileage or cash for each ride. The campaign totals participant distance for a charitable donation. It is also not the redistribution mileage program above: that program uses the narrower 07:00-09:00 and 17:00-19:00 windows and rewards specific station-balancing trips.

Practical Notes

  • Check the app before walking to a station.
  • Expect empty or full stations near busy parks and subway exits.
  • Return at a station, engage the lock, and check that the app confirms completion. The geofence can accept a nearby false return.
  • At a busy station, leave the bike where it does not block pedestrians.
