If you're feeling overwhelmed with nostalgia right now, don't worry—your little girl or boy can get one, too, with the Hotrock 16 Coaster. It has one gear that's easy to spin and a simple-to-use coaster brake. This means that the bike is easy to ride, but just as importantly, it means less maintenance for you. We also made the bike to be plenty tough to stand up to the hard use that every kid is capable of, with a durable 16-inch A1 Premium Alloy frame that has an ultra-low standover to make getting on and off the bike a breeze. Then there's a bombproof fork that'll take curb hops in stride and a whole host of strong components. Add it up, and you get a machine that's built for pure fun with a thoughtful design that'll have you spending more time riding with your kid and less time at the repair counter.

  • Tough, light, and durable, the A1 Premium Aluminum frame is built to stand up to years of tough riding.
  • A steel coaster brake makes slowing down and stopping as easy as can be.
