The Trek Kids Wahoo 20 Trail Bike turns neighborhood loops and dirt paths into confidence-building adventures, giving young riders a real mountain bike feel that’s light, responsive, and ready for after-school laps that somehow stretch until dinner.

From Trek’s trail-inspired geometry to the Wahoo 20 Trail’s lightweight carbon fork and hydraulic disc brakes, every detail is built for control and durability, with a 9-speed microSHIFT Advent drivetrain, 20x2.20" tires, and compatibility for an internally routed 31.6mm dropper post as skills level up.
