Couldn't find that loop in Korea. Luckily I was planning to travel to Hong Kong, so I decided to order it online in advance and go pick it up later. It was a very smart decision, and we felt safe with the loop. Without it, sometimes a child fell sideways. Hong Kong was very crowded, and the light and compact Micro Trike was perfect for walking down the street. The loop added safety to our convenience.
The shop's staff was very friendly (even though the woman was not the owner). The shop was also selling various kinds, so if we had lived in Hong Kong, we would also buy a bike and a balance bike.
