Most of the bikes I see in Taipei are basic mountain style bikes from Giant or Merida with little in the way of personalization. Check out this marvelous rig with the Kirin Ichiban Beer customization, though.
The bike itself looks like a junky Next "full suspension" "mountain" bike shaped object. The owner has obviously put a lot of love into the look of the bike, however, by painting the frame and carefully applying decals and detailing. That rear disc wheel is amazing.
Kirin Ichiban is a Japanese beer brewed from rice.
