Yul-dong Park System 율동공원
318 Yul-dong, Bundang-gu, Seongnam-si, Gyeonggi-do, South Korea.
I wouldn't recommend this trail. But if you're addicted to the sport and you need your fix however you can get it, then the Bundang trail is your spot. Some of this trail I would consider green and has good flow to it. And there are other parts of the trail that are steep climbs including multiple hike a bike sections. I would say my experience was 30% biking and 70% hike-a-bike at my intermediate ability. Quite a bit of the trail is nicely graded it just needs a mountain bikers touch to smooth it out and make it more rideable.
