Thank you Dahon

Taipei has well-developed bicycle-only tracks that skirt the city, but it lacks similar infrastructure in the city's core where cycling on the street can be dangerous. In addition, cyclists breathe in more tailpipe exhaust than other commuters. One British study even suggested that the benefits of the extra exercise are negated by filling your lungs with all that cancer-causing pollution. An annual survey of 1,000 residents conducted by the city's Department of Transportation found that less than three percent of Taipei residents use bicycles as their main form of transportation. "If Taipei could improve its bike lanes, we'd see more people riding bikes to work. We already see more people riding bikes since they started upgrading the bike lanes on the rivers. If you establish that same kind of network in the city, increase bike access on bridges, and introduce congestion charges, there would definitely be more people riding to work," said Dahon Vice President Josuha Hon (韓安石) in an e-mailed statement. His company saw its UK sales jump 40 percent after London started charging motorists to enter the city center in 2003, according to Dahon's Web site.
