    About

    Since 1974, we've had one goal: Innovate and inspire to improve riders' lives.

    Innovation

    Innovate or Die. Three words behind every design decision we make.

    Stories

    Bikes are part of a greater culture with tremendous stories. This is where you'll find them.

    Sustainability

    We recognize that the decisions we make have social and environmental impacts and that we are responsible for minimizing them.

    Retül

    Helping riders make data-driven decisions to improve the ride.

    Outride

    The Specialized Foundation uses cycling as a tool for children to achieve academic, health, and social success.

    With our Riprock Coaster 12, riding gets boiled down to its simplest element—fun. And to make sure of it, we designed the bike with tons of cool features that are easy for your little ones to use, like a coaster brake for simple stopping, wide 12x2.3" tires that increase stability and confidence, and tough components that will stand up to years of abuse. It"s the perfect bike for your little ripper to start getting out on the trail with—we just wish that we had one when we were kids.
    • 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.
    • 12x2.3" Rhythm Lite tires deliver tons of traction, comfort, stability, and fun over all types of terrain.

    我们的Riprock 倒刹 12寸可以让骑行只留下简单的元素——快乐。为了保证这一切，我们在设计时融入了诸多特点，让我们的小朋友更容易使用，比如倒刹的简单制动，12x2.3宽胎带来的更高稳定性和更强的自信，坚固的配件能够承受多年的粗暴使用。这是你家小朋友开始林道骑行的好伙伴——我们真希望我们小时候有这么一台车。
