folding bicycles comparison - Dahon Jack
Dahon Jack 26-Inch Folding Mountain Bike
Dahon Jack 26-Inch Folding Mountain Bike
Why Jack? Well Jack Ass, Black Jack, and Jack Daniels were just a few of the (printable) names that were thrown on the table as we tried to find a name suitable for this burly beast of a bike that we'd created. So we chose Jack and we think it fits just fine. The Jack isn't designed for all-out speed - that's for racer boys in spandex - it's designed to go at any pace you choose and to roll over anything in its path. We designed the Jack around a beefy 7005 aluminum frame and phat Schwalbe Big Apple tires. The custom SRAM drivetrain has only seven speeds to keep things simple, but enough gears for most anything you're likely to encounter in the city. What kind of bike is this? We don't know. Jack.

Hit the trail, the boardwalk or a winding two-lane in five seconds or less. And you won't a need a rack for this mountain bike, as a conventional trunk will do. The Dahon Jack is straightforward transportation for on and off road, featuring a simple seven speed 37-101-inch gear array and a beefy Joe Murray design 7005 double-butted aluminum frame with forged lattice hinge and a head tube made with patented ReBar technology. Other features include an integrated, straight blade fork, a Dahon Fusion headset with a Zero stack cartridge, and a WTB Speed V saddle attached to an aluminum, Microadjust seat post to ensure comfort and stability. The NVO InfiniteAdjust stem is made for instantaneous stem height adjustments, and the braze-ons for rack and mud guards will accommodate any trail gear you want to add.
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.

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

Tokyo Birdy!
Tokyo Birdy!
End of short riding session. Albeit that it's just around my house and to the nearby park. Overall impression is that the ride quality is quite good. Gear shifting attributes of the Rohloff cannot be asscertain as the only other comparison I have at the moment is a 6 speed Shimano. Definitely an improvement, but there were sometimes I think the gear didn't shift into place. I'll have to check again. Braking power is definitely better than other bikes I've tried. Especially when going down a very steep slope, the control was excellent. The noise is quite evident though. The handle bar position is not quite comfortable. This could be due to two reasons. The Litepro Cabon Fibre handle is slighter further out than the stock handle. And the Litepro seatpost puts the seat slightly back. This could add up to a 5 cm difference. I'm aiming for a more upright position for comfort so this will need to be addressed. I may switch back to the stock seatpost but when I bought the bike, some of the original parts were not returned to me after the Litepro "upgrade". Arrgh!! The San Marco saddle from Zonocolan is not the most comfortable. Whilst it looks nice and slick with matching color, my ass hurts after the short ride. Perhaps it needs time to break in a little. For a Birdy with a comfort stem, this is a strange choice of saddle. The stock saddle on European R&M models and the Japanese BD-1 models seems much more comfortable. The Marathon Racers tyres are good, on pavements and slightly off-road condition. Not sure if I will switch to the Schwalbe Kojak or the Panaracers yet. We'll see. For now, I'll stick with the Marathon Racer. Taken with Canon FD 85mm f/1.2L on Sony NEX-3. DSC00384E
