STRONGEST、SMALLEST、LIGHTEST

The folding bike’s history has been one of gimmickry; a single redeeming quality, offset by impractical, unreliable designs and substandard components. It has been a solution in search of a problem; too flimsy for the serious cyclist, too gimmicky for the casual rider, and about to become obsolete. CHANGEBIKE proudly offers a new member to an old family. Not a folding bike, but a bike that folds.

The Change represents a revolution in cycling technology. It is the only bike of its kind to be EN 14766-certifed, meaning that it can hold its own with any mountain bike, both in specs and looks. But that’s just the half of it.

The unit has the smallest folded state of its kind, and weighs less than ten kilos, making it small enough to fit in your trunk and light enough to be picked up with ease. The folding is easy and toolless and the design is sturdy and comfortable. The Change bicycle, from CHANGEBIKE, is the only bike you’ll ever need.

FOLDING BIKE COMPARISON

 

Change Bike

Other Folding Bikes

Folding mechanism design

  • The Full Triangular Structure Design, no cutting or Perforating tube.
  • Obtained Innovation patents Internationally.
    It is the ONLY folding frame design to achieve
  • Down tube is a key support of a bike. Without down tube, the bike can't withstand the heavy.
  • Double-Quick Release. (Including second safety-locking device)
  • No any mechanical part on top tube, no fear of straddling the bicycle.

  • Use folding boxes or single-beam designs.
  • Does not comply with the principles of mechanics.
  • Defective structure by cutting or perforating tubes.
  • No down tube-the frame becomes weaker.
    Single locks employed.
  • Folding mechanical parts designed on top tube or aside, it is easy to hook the clothing or interference when straddling the bicycle.

Frame Geometry

  • The folding design doesn't destroy the frame geometry, so it can be applied to various folding bikes (eg: mountain or road bikes) to achieve the best frame geometry.
  • 26 inch/700C full size bike is low center of gravity, allowing greater stability.
  • The folding design limited the frame geometry, can only reach approximate, not the best frame geometry.
  • Single beam design has long lever arm which fits lower tolerance small folding bike. Yet, it is high certer of gravity, unstability, easy to fall down when riding downhill rapidly.

Safety Certification

MTB / 700C frame passed Strictly safety test of European Standard EN 14766/ EN14781

  • Frame and Front Fork Assembly-Impact Test (Falling Mass)
  • Frame and Front-Fork Assembly-Impact Test (Falling Frame)
  • Fatigue Test with Pedaling Forces
  • Fatigue Test with Horizontal Forces
  • Fatigue Test with a Vertical Forces
  • Unable to pass the tests.

Frame Size Availablity

  • Multi-size frame available (17", 18", 19", 21" / 460mm,520mm) to meet people of different height and ergonomic.
  • Most folding design can only make one-size folding bike, does not match the ergonomic.

Folded Size

  • Smallest (Compact)
  • Front triangle frame enables folded ( close to a 26-inch/700C wheel size) that can be easily placed in the trunk and the front wheel can be fixed on special natch to prevent scratching the bike body.
  • Bigger
    Part of the front triangle frame can not be folded.

Can Stand after folding?

  • Able to Stand after folding.
  • Several Designs
    Unable to Stand after folding.

Automatical Chainwheel protection device (Chainwheel won't touch ground after folding)

  • It is the only one to have chainwheel protection device. Seat tube automatically elongates to avoid chainwheel hitting ground after folding. While riding (unfolded), it automatically retracts to avoid affecting the ride. These are all the automatic reaction, without any additional actions during folding.
  • No Chainwheel Protection device.
  • U-shaped bracket of chainwheel protection is welded. It would be hitting something when riding.

Special notch hook design.

  • There is a special natch designed at chain stay to fix the removed front wheel. The entire folded unit can be carried with one hand.
  • No fixed front wheel design, needs to carry it by another hand.

The weight of the bike

  • By Triangular geometric mechanics to achieve the strength, reduce bike weight to less 10KG.
  • Single beam tube design doesn't match Triangular geometric mechanics so it has to informce pipe thickness and hings, and increase tube diameter lead to bikes become heavier.

Part Compatibility

  • 100% part compatibility. Replace Change frame, your bike can become MTB folding bike.
  • Many non-standard (customized) folding mechanisms makes the difficulty in obtaining spare parts, and causes higher maintenance costs.

Storage design of Carry bag

  • The carry bag is waterproof and double fabric protection design at the bottom to increase load.
  • Folded dimensions close to a saddle size, like a small pouch.
  • Carry bag normally is designed to be a big bag. When you carry a folding bike to go out for riding, you may find no place to put the bag.
