    Traction, control, confidence, and fun—the Riprock 20 Coaster is the perfect bike for your kid to start hitting the trails with. And with the simple coaster brake design, safety and fun aren"t mutually exclusive anymore. While there are many notable features that make the Riprock awesome, it"s the 2.3-inch tires that provide a high degree of, well, shred-ability—delivering exceptional traction, control, and confidence for riding rough, off-road sections and city streets alike. And when you combine the big tires with sturdy 20-inch wheels, an easy-to-use coaster brake that all but eliminates the threat of the dreaded endo, and a single-speed setup, you have the perfect mountain bike to get your little Ripper out on the trail.
    • The A1 premium aluminum frame is lightweight and built to withstand the tough use by kids, while the geometry features an ultra-low standover that makes it easy for your little ones to fit on and grow with the bike.
    • Steel coaster brake is a reliable, easy to use brake perfect for safe stops and awesome skids.
    • 20x2.3" Rhythm Lite tires deliver tons of traction, comfort, stability, and fun over all types of terrain. 

    牵引力，控制力，自信心和乐趣——Riprock 20是您孩子学习林道骑行的好伙伴。采用简单的倒刹设计，安全性和趣味性不再相互排斥

    Riprock非常棒，它有许多值得称赞的特点。它的2.3英寸的轮胎为骑行崎岖的越野路面和城市道路带来的超强抓地力，控制力和绝对的信心。当大轮胎与坚固的20英寸轮组相结合，再加上机械碟刹和7速变速，你就得到了一辆非常棒的山地自行车，可以让您的小开膛手踏上享受美好林道骑行时光的路。

    • A1高品质铝合金车架在轻量化的同时能够经受小朋友的粗暴使用，超低跨高的几何让车辆更好地贴合小朋友不断变化的身高。
    • 钢制倒刹可靠，易用，非常适合安全地停车或者酷炫的甩尾。
