Assembly of the Bike: This bike comes mostly assembled. Minor assembly is required before the bike can be used. About Dahon The Dahon story begins in 1975. At the time, Dr. David Hon, founder of the company, 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 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. Despite his success, Dr. Hon eventually found the work 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. Brainstorming 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. 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 and transformed, to make it more broadly functional and needed to integrate more readily with other forms of environmentally-sustainable transport, like trains and subways. Dr. Hon's solution: a portable folding bicycle. 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. .com Bicycle Buying Guide Finding the Right Bike To really enjoy cycling, it's important to find a bicycle that works for you. Here are some things to keep in mind when you're in the market for a new bike: The Right Ride In general, bikes are broken down into three major categories: Road and Racing Bikes--As a general rule, road and racing are built for speed and longer distances on paved surfaces. Thinner tires, lightweight 29-inch (700c) wheels and drop bars that allow for a more aerodynamic position are the norm. Most road bikes, regardless of price, offer many gears for tackling both hilly and flat terrain. Mountain Bikes--With their larger tires, hill-friendly gearing and upright position, mountain bikes are very popular for all types of riding, both on pavement and off. Mountain bikes that are designed specifically for rugged trail use typically feature a suspension fork. Some may have rear suspension, as well. A quick change of the tires on any mountain bike--even one that you use regularly on trails--adds to its versatility and makes it a worthy street machine. Comfort/Cruiser Bikes--For tooling around on bike paths, light trails, or for cruising a quiet beach-side lane, comfort/cruiser bikes are the ticket. With a super-relaxed riding position, padded seats, and limited or no gearing, these bikes are made for enjoying the scenery and having fun with the family. The Right Price A bike's price boils down to three essentials: frame materials, bike weight, and component quality and durability. Entry-level--You'll find a wide range of comfort and cruiser bikes in this category, as well as some lower-end mountain bikes and road bikes. Most will have steel frames and components that are designed to last for several years with frequent use. Mid-range--Bikes in this range may feature a lighter aluminum frame with mid-range components that keep performing after miles of use. If you're looking for a quality bike that is relatively lightweight and will stand up to abuse, this is the "sweet spot." Most serious commuter and touring bikes fall into this category, as do mid-range mountain bikes with a decent front suspension. High-end--Racers and serious enthusiasts who expect lightweight, high-performance components will want to stick to this category. For road bikes, exotic frame materials (carbon fiber, titanium) and ultra-lightweight components can add thousands to the price tag. Mountain bikes in this class often feature advanced front and rear suspension technology, as well as components designed to handle lots of rugged trail action. The Right Size Fit is crucial for comfort, control, and proper power and endurance on a bike. Here are some basic bike fit tips: Stand-over Height--To find out if a bike's overall height fits your body, measure your inseam. Next, determine how much clearance you'll need between your crotch and the top tube of the bike. For a mountain bike, you'll want three to five inches of clearance. A road bike should offer between one and two inches of clearance, while a commuter bike should have two to four inches. Compare the stand-over height for a given bike to your measurements (inseam + clearance) to determine the right bike height. Top Tube Length--You can measure your torso to get a good estimate of proper top tube length. First, make a fist and extend your arm. Measure from the center of your fist to the end of your collarbone (the part that intersects your shoulder). Next, measure your torso by placing a book against your crotch with the spine facing up. Measure from the spine to the bottom of your throat (the spot between your collarbones). Finally, add the two measurements (arm length + torso length), divide the number in half and subtract six inches. This is your approximate top tube length. Compare this number to a bike's posted top tube length. You can allow for about two inches longer or shorter, as most bikes can be adjusted via stem length/height and saddle fore/aft position to make fine adjustments to the fit. Bikes for Women--Proportionally, women tend to have a shorter torso and longer legs than men. Bike makers design women's bikes that offer a shorter top tube and many comfort/cruiser bikes built for women may also provide more stand-over clearance. The Right Accessories When you make a bike purchase, don't forget these crucial add-ons: Helmet (this is a must!) Seat pack Lock Hydration pack, or water bottles and bottle cages Spare tubes Portable bike pump Gloves

Dahon Jetstream
I bought this bike to ride between the train station and my house. Initial impressions: The bronze and black colors go well. No kickstand, nor a seatpost pump (other Dahon models have them standard), and the seams on the frame look unfinished.You need a shock pump to adjust the rear suspension. Adjusting the read suspension correctly makes a huge difference. I inflated the tires to around 60 PSI which was too low. I got a flat in the rear wheel. After patching it and inflating to 80 PSI, I haven't had any problems. I had to go to schwable website to get a replacement inner tube, because my local bike shops were out of Presta tubes in this size. I bought a cateye taillight and tried to attach to the seatpost. The seat post was too wide for the clamp so I had to order the SP-9 clamp from the cateye small parts store.When folded, there's supposed to be a velcro strap that holds the wheels together according to the manual. I must have thrown it out on accident with the box.Overall, the bike rides very nicely. The grip shifter is great, nice suspension, and the brakes are solid. I'm average height, and the bike fits me perfectly. If you're really tall, it may not be the best bike for you.

I love my Dahon Jetstream
I love my Dahon Jetstream! It's a very aggressive looking bike which makes it a great conversation piece. Amazon had the best price on this bike. The only thing I didn't like was the fact that once I received the bike I had to take it to a local bicycle shop and have everything inspected and tuned up. If not it would void my warranty on the bike. That's around $100. So be sure to factor that into your purchase price if buying online.

Last Of The Breed??
As near as I could tell, this was the last one available Stateside at the old price of $650. Probably a returned item as it arrived damaged & the packaging was trashed. The chainring was bent but Dahon made it right with an equal or better crankset. But once it was repaired & tuned up it turned out to be a very good little bike. I use it for car camping. It's not a mountain bike, but the suspension handles just about any road condition, quite comfy. It looks like these bikes are now running in the $1400 price range, not sure if I would spend that kind of money on one anymore.

Love it even more after 2 years riding it in San Francisco
Dahon Jetstream P8 Folding Bike I have had this bike for 2 years now, riding it 3 or 4 times a week, and updated the review to 5 stars because like a good woman, it has never failed me and the minor shortcomings seem less important compared to the fun, usefulness, and overall beauty of it. The bike is very strong and the industrial look never fails to get positive comments. The brake issue has not been critical even on steep hills. I would love to see dahon bring this bike back at the same price or even a bit higher but not the 1200 or so I see rumored.A smooth and fun ride. Well built with a strong and light frame. This bike it totally underrated. I know people write pages about their Bromptons and Bike Fridays, but I found them jittery (and expensive) in comparison. Also for me 16 inch wheels are just too small. I like the Dahon Mu XL which is lighter. But without a suspension, I found the ride too harsh. My other bike is a nice hybrid, but I usually choose this one for several reasons: 1) It is simply a blast to ride - with the same size wheels as a BMX, this bike is maneuverable but not jittery. Jumping curbs is no problem, and lowering the seat makes for a BMX ride feel 2) It is light and easier to carry down the stairs using the frame as a handle 3) I can throw it in my car so when I have to re-park (due to the 2 and 4 hour zones), I can ride back. I actually enjoy having to move the car and being forced to take a ride ! 4) If I ride somewhere and dont feel like riding back, I can throw it in a taxi or bus with no problem 5) I don't need to bring the extra tube and tools, because if there is a problem - see number 4. 6) Despite, their desire to be bike friendly, San Francisco is not a very safe place to ride a bike. The roads are crap. The bike lanes are generally dangerous and there are thinks happening in every direction like bad drivers, doors opening, people right turning without looking, people who think bikes don't belong on the road, potholes, streetcar tracks, and mostly people not paying attention. So it is often better to ride on the sidewalk (politically incorrect but true). With this smaller bike I feel the reaction of the people is minimal when compared to approaching on the sidewalk on my full size hybrid. Plus with the low stepover height, jumping off to walk, then back on is a non issue, so I am more likely to do it. 7) I can take most of the terrain with this gear set, if not - just jump off. Be serious, do you really want to ride up Hyde street? 8) If you don't want to carry a lock, most places will let you bring it in. and 9 ) A smooth and fun ride. 10) Took it over the GG bridge to Sausalito several times with no problems. So great for moderate length trips too, unlike most folding bikes. 11) The industrial look of this bike is just cool, and I get lots of positive comments even from kids.Weaknesses - the front brake fades in an out as the front suspension operates, but this does not make me less confident on a steep hill like I expected as it is consistant. Also the brake levers are poor. Changing for a different Avid set (only $25.00) improved the brake feel (but not the fade in and out). Difficult to fit a rack. Shifting accuracy is not that great. The magnetic latches are useless.Folding: Yes the fold is not tiny, and it is a bit awkward when folded, but if you really use a folding bike you will find a petite fold is not the key issue. I still fit it into the so called storage area of a friends Smart Car(a very tiny thing ). Usually I keep the frame unfolded with the handlebars and petals folded, which makes for a good fit in a narrow hallway. And this fold gets me into most places with my bike anyway. By the way, for a cleaner fold, I recommend folding the front wheel to the inside of the fold, not the outside as recommended in the instructions.Riding this bike for 2 years in San Francisco, I find it just fun to ride and very smooth. I highly recommend this bike !
