Why Choose A Carbon Fiber Bicycle?

  1. Lightweight. The weight of a frame made of carbon fiber is 1/4 of that of an ordinary alloy frame.
  2. Good shock resistance. Comes with a damping effect, no need to use shock absorbers.
  3. It can greatly reduce wind resistance and improve the comfort of cycling.
  4. The carbon fiber composite bicycle has a strong structure and is not easy to deform.
  5. Good safety. The matrix of the carbon fiber composite material is a continuous phase that surrounds a large number of independent fibers, forming a dynamic and uncertain system. When this multi-phase material is impacted, even if a small amount of fiber breaks, its load will be quickly redistributed to the undamaged fiber so that the structure can still bear it. This greatly improves the safety of riding.
