During my tenure in HK, I was limited to commuting. And doing so was worrisome because while I was there (and maybe things have changed) there is no theft insurance on bikes, and no one rents there. Rides to the south side of HK island were fun, as well as rides into the new territories.....and that's about it. The bike thieves there either grab it and stuff in into a van and split, or they will disable it and come back for it later. One of my bikes almost became victim to scheme number two. I paid a watchman to keep an eye on it overnight until I could arrange a tow to a ship to get it repaired. I was lucky.
Living on Taiwan was different. I didn't take advantage of the beautiful island I called home for three years. The mountains, the tribal people and the food were amazing. I only experienced 1/100th of what the island had to offer. I miss it horribly.
Sorry, went a bit off topic here.
