Folding Mechanism Design & Frame Geometry

ChangeBike:

• The Full Angular Structure Design, no cutting or Perforating machine. 
• Saved modification protection abroad. 
• Double-Quick Release. (Including second security locking mechanism)
• No fixed part on the top package, no doubt of staddling the bicycle.
• A down tube is a key support of a bike. Out a down tube, the bike can’t resist the heavy. It is also able to stop throwing water directly on the glass.
• The folding device doesn’t destroy the mold geometry, so it can be used to many folding bikes (eg: mountain or road bikes) to deliver the most suitable frame geometry. 
• 700C full-size bike is a low heart of pressure, providing higher security.
• Other Folding Bikes: Use folding cartons or single-beam devices. It does not comply with the laws of mechanics.
• Poor construction by cutting or drilling tubes.
• Exclusive locks used.
• Folding construction parts created on the top tube or aside, it is easy to hook the clothes or check when riding the bicycle. 
• Without a down tube, the frame grows weaker. When cycling in a wet area, water is expected to throw on the bottle.
• The folding design limited the frame geometry, can only reach fair, not the best case geometry.
• Single-beam design has a long lever arm that fits the lower-end small folding bike. Yet, it is a high focus of pressure, anxiety, easy to fall when driving downhill fast.
