Antony Lo is one happy biker. He is 60 but looks younger, with a body buffed by commuting 130 miles a week on his bike. He is also president of Taiwan-based Giant, the world's largest bicycle company, where sales are soaring, helped along by global anxiety over oil prices. With undisguised glee, Lo says: "High-priced gasoline is here to stay. I tell my people we are just at the beginning of a very big cycling boom."
