Recumbent Exercise Bike. Less than 1 year old. In perfect shape. Bike has 8 different levels and is definitely a smooth ride. The bike is light weight and easy to move. I still have the box and it is easy to disassemble, so could be transported by two people quite easily on the subway. Paid $350 for it new, asking 100,000 Won.
I am located in Geumhoe, near Singgeumhoe station on the purple line. Email if you have questions. The bike is available anytime after the 27th.
