The front suspension fork enhances comfort by absorbing shocks, although the lack of rear suspension might be a drawback for some rough terrains. The aluminum frame keeps the bike lightweight yet durable, and the 26-inch wheels with 4-inch wide puncture-resistant tires offer excellent traction on various surfaces including sand, snow, and gravel. The bike is equipped with front and rear disc brakes, providing reliable stopping power and quick heat dissipation, which is crucial for downhill biking. It also features a professional 7-speed transmission system, enhancing its versatility and climbing capabilities.
