GV-10G
Folding Gravel Frame

The GV-10 folding frame is designed with full consideration for compatibility with rear-drive electric kits，It features the following characteristics:

The new front triangle frame design allows for battery placement and features enlarged cable exit holes that can accommodate up to six wires, specifically designed for electric kits.
The battery is easy to remove, making it convenient for charging and replacement, without interfering with the folding mechanism.
This folding bike is equipped with an electric assist system, making long trips and various terrains easier to handle, ensuring a more effortless and enjoyable journey.
Recommended: 36v 250-350w rear hub motor, 7-10S cassette motor, 135mm dropout width, and a 7-10Ah battery.

CHANGE Foldable Bike Frame

"CHANGE Folding Frame: Innovative Design, the Perfect Blend of Stability and Aesthetics"

The CHANGE folding frame features a full triangle and diamond structure, ensuring stability and comfort. The uncut and unperforated frame maximizes strength and durability.

Our folding mechanism is patented globally, with gravel and mountain bike frames being the only ones to pass all five ISO 4210 safety tests, ensuring exceptional safety.

Optimized Down Tube Design: Unlike many folding frames, CHANGE reinforces the down tube for added sturdiness, higher rigidity, and better performance on all terrains.

Dual Quick-Release Design: Includes a secondary safety locking mechanism for faster, more reliable folding and unfolding.

Top Tube with No Mechanism: A clean top tube design ensures a natural, comfortable ride without interference when mounting.

CHANGE Folding Mechanism: Auto-Alignment Function for precise frame alignment, ensuring better riding stability and control compared to traditional hinge systems. The frame, front, and rear wheels automatically align when unfolded for optimal performance.

CHANGE BIKE	Other Folding Bikes
Folding mechanism design
The Full Triangular Structure Design, no cutting or Perforating tube. Obtained Innovation patents Internationally. Double-Quick Release. (Including second safety-locking device) No any mechanical part on top tube, no fear of staddling the bicycle. Down tube is a key support of a bike. Without down tube, the bike can't withstand the heavy. It is also able to prevent splashing water directly on bottle.	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. 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
It is the ONLY folding frame design to achieve strictly European 700C frame safety test, EN 14781 certification. 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 Vertical Forces	Unable to pass the tests.
Frame size availablity
Multi-size frame available (460mm, 490mm, 520mm, 550mm) 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) 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.
