Technology

The future is folding

The Dahon story begins in 1975. At the time, Dr. David Hon, our founder, was a physicist at Hughes Aircraft Corporation, in California, working on highly classified government research projects. Considered a leading expert in solid-state laser technology, Dr. Hon had already been awarded numerous U.S. patents (Patent 4,344,042, Patent 4,178,561, Patent 4,019,159 and Patent 4,010,397) for advancements in laser technology. Breakthrough laser technology that he and his team developed would later be used on NASA space shuttles, US missile guidance systems, and laser-guided anti-aircraft guns.

Yet despite his success, Dr. Hon eventually found the work at Hughes Aircraft unfulfilling, because his energies were devoted to instruments of war, rather than for the betterment of society. Then, in 1975 came the oil and gas crisis and the seed for Dahon was sown.

One afternoon, in his third week of waiting in hour-long lines to buy gasoline for his car, Dr. Hon was struck by the magnitude of the world's dependence on oil, a non-renewable resource that would likely be depleted within the lifetime of his grandchildren..

Brain-storming for solutions to weaken the world's dependence on oil, Dr. Hon ended up going back to his primary mode of transportation in college - the bicycle. Totally clean, and just as important, cheap enough for people around the world to access, Dr. Hon considered the bicycle to be a good candidate as a solution. However, the bicycle as it existed at that time was not without shortcomings. While the bicycle was perfect for short trips, it was not practical for longer trips, for example, if you lived 30 miles from work. The bicycle needed to be improved, transformed, to make it more broadly functional. It needed to integrate more readily with other forms of more environmentally sustainable transport, like trains and subways. Dr. Hon's solution - a portable folding bicycle. Next came the hard part: turning his ideas into reality. Working evenings and weekends in his garage over the next seven years, Dr. Hon built dozens and dozens of prototypes, trying to perfect a folding bicycle that would maintain the riding performance of a regular bicycle but would fold quickly and to a compact size.

Finally, 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.

We're happy to have made such a difference in the lives of people all around the world. But rest assured that we aren't slowing down - there are many more revolutions to be started.

 
 
fusion.jpgFusion TecnologyFolding bicycles traditionally lack stiffness in the handlebar/stem (we call if a handlepost) assembly. Long extended handleposts are long levers that exert a tremendous amount of force on frames, headsets and forks. Traditional bicycle technology wasn´t designed for the handlepost found on folding bicycles so we developed new technology. Our patented Fusion Technology, improves on the "theadless" stem of modern mountain bikes and blends frame, fork, and handlepost into a single integrated, inmensely strong, structure. Fusion technology boots fornt-end stiffness by more than 30 % compared to traditional quill desingns. Dahon patented Technology
 
biologic.jpgBiologic II Frame Technology

Small wheel bikes have a reputation for "twitchy" handling that discourages riders used to bikes with larger wheels. But "twitchy" handling is the result of poor frame geometry more than wheel size. BioLogic™ II frame geometry is the result of almost 25 years of refinement by the product team at Dahon: a group that ranges from professional cyclists to physics Ph.D's. We've researched and tested every aspect of frame geometry from seat and head tube angles, to fork offset, to fore/aft weight distribution, to reach, to BB height. BioLogic™ II geometry is found on every one of our compact bikes and makes our bikes the most stable and secure handling folding bikes on the market.

 
dfs3.jpgDFS Technology

All Dahon compact bikes fold the same way.

Step 1: lower the seat post into the frame

Step 2: fold the handlepost down

Step 3: fold the frame in half

Sound familiar? If it does, it's because the DFS folding technology that we developed over 25 years ago is now used by over 90% of folding bicycles on the market. But we haven't stood still - we've refined the design so that our bicycles fold more easily, quickly, and to a more compact size than just about any other folding bike on the market. Dahon patented technology.

 
zorin1.jpgBiologic Zorin Postpump

The BioLogic™ Zorin Post Pump is an ingenious combination of a seat post and powerful floor pump. The pump mechanism is hidden inside the seat post and uses the seat post as the outer wall of the pump. The pump is always at hand, hidden from the elements and thieves. Ergonomically, the PostPump is just like a floor pump: you stand while you pump and use the saddle as a handle. Max pressure is 110 psi with fewer than half the strokes of the best mini pumps. So say good-bye to kneeling in the dirt with a mini pump that will give you an arm cramp before your tire is filled and ready to ride. Dahon patented technology.

 
dynamo.jpgBiologic Joule dinamo Hub

There's nothing we like better than clean energy. A hub dynamo is the most efficient way to generate electricity for your bike light. The hub is embedded with a series of small magnets that generate electricity when the hub is turned while you ride. The Joule hub features a polished aluminum hub shell and is made to our 74mm compact width specifications. It is one of the lightest and most efficient hub dynamos on the market.

 
qfork.jpgKinetix Q ForkTo develop our revolutionary new suspension fork, we partnered with German-A, the same suspension specialists that conceived the suspension on the Specialized Epic. The Kinetix Q fork features a parallelogram design that drives a suspension unit in the steerer tube. Compared to other fork designs on the market, the Q is light, extremely stiff, and superbly supple. The path of fork travel more closely matches the angle at which road deformities hit the front wheel. And unlike telescopic fork designs that are inherently susceptible to stiction, the Q is largely stiction free. The design of the fork inhibits brake dive for improved handling. The Q fork features our patented Fusion coupling system that integrates the fork, frame and handlepost. Patented technology.
 
radius.jpgRadius Telescope HandlepostThe Radius handlepost might be the single most impressive piece of engineering on our bikes. The Radius features patented Fusion technology that allows it to flow seamlessly into the frame head tube and fork. The Radius features beautifully rounded, tapered lines, yet the forged base and patented Fusion coupling system add up to a dramatically stronger handlepost than the version that it replaces. The Radius features a patented InSide™ locking mechanism that is hidden inside the body of the handlepost for a super clean profile. Dahon patented technology.
