Dahon History
In 1982 Dr. Hon introduced the first Dahon folding bicycle to worldwide acclaim. At design competitions around the world, the first Dahon folding bicycle proceeded to win award after award. Full of optimism, Dr. Hon visited major bicycle manufacturers around the world, hoping to find a company to either license his design or build the bike for him. But not surprisingly, none of big companies were interested in his revolutionary new idea.

Undaunted and committed to his vision of environmentally-sustainable transportation, Dr. Hon decided to risk everything and build the bike himself. He quit his job, gathered $3 million dollars in venture funding, re-located to Taiwan, and built a factory. By 1983, Dahon folding bicycles were rolling off the assembly line.

Today, over two million bicycles later, we can proudly say that Dahon has made a difference. From San Francisco to Amsterdam to Rio de Janeiro to Tokyo, people are using our bicycles to get from point A to point B. Governments are integrating portable folding bicycles into their plans for mass transportation. And every one of those big bicycle companies that Dr. Hon visited 25 years ago have now jumped on the folding bike bandwagon.
