Boy's Hotrock 20 Street

Part No.  
Your little dude might not be ready or interested in riding trails, but what kid doesn't want to cruise the neighborhood on a miniature performance machine that would make Mom and Dad jealous? Good question. Let his bike be the next topic of conversation at the tree fort with the Boy's Hotrock 20 Street. It features a lightweight, yet durable, 20-inch A1 Premium Aluminum frame that's designed to take a hit while they're goofing off, while a super tough alloy fork is designed to withstand curb jumps galore. Then there are a whole host of other components that are plenty tough enough to stand up to your little man, so you can rest assured that you'll be spending more time riding with your kid and less time waiting in line at the repair counter.
  • Tough, light, and durable, the A1 Premium Aluminum frame is built to stand up to years of tough riding.
  • A straight blade alloy fork is strong and durable, so it will withstand your little ones trying to catch air for the first time.
