Built for young riders ready to explore singletrack, the Trek Wahoo 20 Trail pairs a lightweight Alpha Silver Aluminum frame with a carbon fork and trail-ready 20x2.20" Kenda Amrak tires. The 9-speed microSHIFT drivetrain and Tektro hydraulic disc brakes provide confident shifting and braking performance across varied terrain. With kid-specific touchpoints, integrated light mounts, and a total weight under 22 lbs, it’s optimized for control, comfort, and off-road capability.
