Why We Like The Grunge 20 in Single Speed Bike

GT's Grunge 20 in Single Speed Bike is designed to test our kids' limits and push them further. It's constructed with 20-inch wheels and all-terrain tires that can take on a good variety of territory, and our little rippers will benefit from the responsive handling this ride can provide. Powerful brakes offer stopping power that inspires confidence, and a low and stable geometry keeps them moving and grooving with ease.

  • Start off strong with an easy-to-ride bike
  • 20-inch all-terrain tires offers smooth rolling over most surfaces
  • An aluminum frame is lightweight and durable
  • Soft rubber grips provide traction for smaller hands
  • A low and stable geometry inspires confidence
