Seoul's bike-sharing scheme, like similar civic ventures in London and Paris, can be used by visitors. The green-and-white bikes and their matching docking stations can be found at over 150 locations across the city. To use, first purchase a voucher at www.bikeseoul.com to obtain an unlock code, which is then keyed in on the bike itself (selecting the 'Foreign Tourist' option).
The bikes cost ₩1000 per hour for up to two hours, and ₩1000 every half hour after that. A deposit of ₩50,000 is taken from your credit card and refunded within 24 hours of the bike being redocked.
Cycleways run along both sides of the Han River past sports fields and picnic areas where there are also plenty of bike-hire stalls (₩3000 per hour, open 9am to 8.30pm March to November), as well as free rental close by the subways at Okso (Exit 4), Eungbong (Exit 1), Gongneung (Exit 4), Yeongdeungpo-gu Office (Exit 2), Sanggye (Exit 1), Gangbyeon (Exit 1) and Jamsil (Exit 2) – which can vary from two hours to all day. Bring your own padlock, and leave a driving licence or other ID.
