1.[High-quality materials] The surface of the extra-large bicycle seat cushion is wrapped with high-quality artificial leather, filled with a large area of thickened gel and high-elasticity high-density memory foam. It is soft and elastic, which helps to absorb shock. 2.[Ergonomics] The overall curvature of the extra-wide convex seat cushion conforms to the ergonomic design, which can perfectly fit your round and convex buttocks. The nose design allows the thighs to move freely without rubbing the inner thighs. It is widened and thickened to get rid of the traditional narrow and long seat cushions and create a comfortable riding experience. 3.[Double shock-absorbing balls] The two shock-absorbing balls placed under the bicycle seat ensure that the impact from bumps, potholes or any difficult terrain you ride is absorbed. The metal alloy seat bow is combined with the reinforced nylon bottom plate, which is light in weight, high in strength and has a long service life. 4.[Enjoy a comfortable ride] The surface of the seat cushion adopts an anti-slip texture design, which is wear-resistant and non-slip, and is not afraid of sweat and rain corrosion. Soft, elastic, non-slip, waterproof and wear-resistant.
