Competitive Advantage:
This 21-speed basic version mountain bike is a highly competitive product. In terms of performance, its 21-speed transmission system is highly flexible. The TX30-7 gearshift, Lingxiang front gearshift, and Lingxiang rear gearshift, combined with the Polysteel three-piece chainring and Sanyou non-positioned seven-piece flywheel, can provide a wide range of gear ratios. When climbing slopes, it can easily switch to a less labor-saving low gear ratio, and on flat roads or downhill roads, it can quickly adjust to a high gear ratio, adapting to different road conditions. The mechanical wire disc brake system has strong and stable braking force, ensuring timely parking on any road surface and enhancing safety. The shock-absorbing front fork can effectively filter out road vibrations, reduce bumps, and enhance riding comfort and handling.
In terms of material and craftsmanship, the high-carbon steel frame is sturdy and durable, capable of adapting to complex riding environments. The double-layer aluminum alloy knife ring is lightweight and has high strength. The Antai flower drum rotates smoothly, reducing resistance. The ergonomic design is considerate. The mountain-specific seat fits the buttocks closely, relieving fatigue from long rides. The straight handle combined with the knife-edge pair handle offers a variety of grip postures, reducing hand fatigue. The PVC anti-slip footrests increase friction to ensure stable and safe riding.
In terms of cost performance, the configuration is balanced without obvious weaknesses, and the price is affordable. It is a high cost-performance choice for consumers with limited budgets but who pursue performance.
