If it's time to stop pushing and start pedaling, the 2015 Specialized Hotrock 12 inch Boy’s Bike makes the transition fun, easy, and sets him up for a lifetime of riding. With a constant desire to innovate and improve on bike design, Specialized have even taken the humble training wheel to a new level. Gone are the days of having to fumble with wrenches to remove training wheels (and then re-fumbling with them when your kid decides they want them attached again), the new 2015 12 inch Hotrock features easy-on/off training wheels that use a large thumbwheel.
