The IOS D9 folding bike is a great alternative to a standard bike. It's compact and lightweight so you can take it with you nearly anywhere you go. RVers will love that it can tuck into one your RV's storage compartments. Urban commuters will love it because you can easily take it with you on a bus, carry it up and down stairs, and store it by your desk. Enthusiasts will love it for its high-end components. The curved frame is also stronger than a standard tubular frame so the bike is sturdier when navigating pot holes, curbs, and bumpy trails. And, unlike a regular bike, you can store a folding bike in a closet so it's out of sight in your home.

Quick and Easy Folding Design

Dahon IOS D9 Folding Bike Being Folded

The IOS D9 takes less than 60 seconds to fold up. You can do it in 4 easy steps. Open the safety latch on the seat post and lower the saddle with it angled slightly to the right so it won't interfere with the top tube when you're folding the bike up. Fold the pedals in. Open the safety latch on the handlebar post and fold the handlebars down. Then open the safety latch on the frame and fold the bike together. There are magnets on each wheel that help hold the bike together in the folded position.

The bike weighs just 26-1/2 lbs so it's easy to carry wherever you go. It's easy to haul up and down stairs or load in and out of your trunk or truck bed. And if you have the carry bag (sold separately) you can haul it on your back like a standard backpack.

  1. Shimano Alivio 9-Speed Rear Derailleur -
    Dahon IOS D9 Derailleur
    The Shimano Alivio 9-speed rear derailleur moves your bike chain quickly and smoothly between the cogs when shifting gears. It provides more precise chain movement when compared with the derailleurs on other Dahon folding bikes. It's positioned away from the chainstay so it won't hit your bike's frame when riding over bumps. It's constructed of lightweight aluminum that is designed for riding on rough or bumpy terrain.

  2. Schwalbe Big Apple Tires -
    Dahon IOS D9 Tires
    24" Schwalbe Big Apple tires are air cushioned for a smooth and comfortable ride on nearly any terrain. They are extra-wide to provide more surface grip on pavement and off-road terrain than standard bike tires. The wheels have double-walled rims that provide increased support when compared with single-walled rims so they're better suited for off-road riding. The front tire also includes a quick-release skewer so you can quickly remove the tire from the bike. Reflective stripes on each side of the tires help keep you visible at night. The tubes have slender Presta valves that require smaller holes than Schrader valves. This type of valve is easier to pump, eliminates the need for a mechanical check valve, and results in a stronger tire rim. For quick tire inflation you can use a Dahon combination seat post and tire pump (sold separately). It replaces the existing seat post and eliminates the need to carry an extra hand pump.

  3. Adjustable Saddle -
    Dahon IOS D9 Saddle
    The cushioned, ergonomic saddle is comfortable to ride on even for long periods of time. It's also easy to adjust to accommodate your height, and you can do it in seconds. Just loosen the quick-clamp, slide the seat post to your desired height, and close the quick-clamp.

  4. Stainless Steel Hinges with Quick-Release Latch -
    Dahon IOS D9 HInges
    The hinges on the frame and handlebar post have stainless steel pins with brass bushings that allow them to move smoothly and to resist wear and rust. A quick-release, ViseGrip latch on each hinge keeps the frame locked tight and ensures the bike won't collapse while you are riding. For extra security there is a DoubleLok knob that pivots over each latch to keep it closed. Simply rotate the knobs and open each latch to quickly fold up the bike.

  5. Hydro-formed Dalloy Aluminum Frame -
    Dahon IOS D9 Frame
    The frame is constructed of Dalloy aluminum that is lightweight yet 20 percent stronger than standard 6061 aluminum alloy. The alloy has been hydro-formed into a slightly curved shape that makes the frame lighter and stronger than standard tubular construction. This makes the IOS D9 sturdier than other folding bikes when navigating pot holes, curbs, and bumpy trails.

  6. Fixed-Height Handlebars with Ergonomic Grips -
    Dahon IOS D9 Handlebars
    The handlebars are firm yet move smoothly so the bike is easy to steer. They are set at a fixed height that leaves you in the perfect, upright position so your back won't hurt from being hunched over. There is an Allen key integrated into the handlebar post that lets you adjust the tilt of the handlebars so your hands and wrists can be placed in the optimal position.

  7. Shimano Trigger Shifter -
    Dahon IOS D9 Shifter
    The trigger shifter is located on the right side of the handlebars next to the hand brake. It lets you easily shift gears up and down using your thumb and index finger without having to move your hand off the grip.

  8. Handlebar Brake Levers -
    Dahon IOS D9 Brake Levers
    The handlebar brake levers are located in front of each hand grip so you can steer and brake without having to move your hands. The right hand brake lever stops the rear wheel and the left hand brake lever stops the front wheel. The soft, ergonomic hand grips are over-sized and easy to grip so your hands won't slide off them while steering.

  9. Tektro Aries Mechanical Disc Brakes -
    Dahon IOS D9 Disk Brakes
    The Tektro Aries mechanical front and rear disc brakes provide greater breaking power and are more suited for hard trail riding when compared with rim V-brakes. They have 160-mm drilled and slotted rotors that attach directly to the wheel hubs and squeeze the pads from both sides of the tire. This ensures your brake pads are always effective, even when hitting large holes and riding in wet conditions. And they won't put wear and tear on your tire's rims like V-brakes do. The single-piece bodies are made of aluminum that resists the heat build-up that many disc brakes can develop with extended use. They also have wear indicators on the pads that identify when to adjust them or replace them.

  10. Shimano Hubs with Stainless Steel Spokes -
    Dahon IOS D9 Hubs
    The Shimano 32H front and rear hubs let the wheels spin smoothly and quietly. The hubs are connected to the rims by stainless steel spokes that are strong and rust resistant. The fork has an integrated crown that provides a safe and sturdy connection to the front hub. The rear hub has an aluminum axle that is lightweight yet stiff so it can easily transfer the force created while pedaling to the rear wheel without breaking or getting too hot.
