Trek Kids Wahoo 20 Trail 20" Bike 2025 Plasma Grey Pearl

Built for young riders pushing into trail terrain, the Trek Wahoo 20 Trail combines a lightweight Alpha Silver Aluminum frame with a carbon fork and hydraulic disc brakes for confident control on mixed surfaces. A microSHIFT 9-speed drivetrain paired with a narrow-wide chainring delivers smooth gear transitions and reliable chain retention over uneven ground. Sized for kids 45–52" tall, this setup features wide 2.20" Kenda tires, a sealed bottom bracket, and an integrated saddle mount for a trail-ready ride that handles serious off-road demands.
