Mountain Flyer
Tested: Specialized Riprock Expert 24

Jun 2017

Plus tires, legit components, and great geometry make for a standard setting kid’s bike. “Hey dad, how do you spell ‘Mac-as-kill’?”, After years of helping my daughter google Barbie — Life in the Dreamhouse, Strawberry Shortcake, GoNoodle and the like, hearing those words drift from the computer desk and out the window to where I was working in the yard just warmed my heart. It’s a mountain biking father’s dream.
