Trek Wahoo Trail 20 Kids Bike
The Trek Wahoo 20 Trail is a lightweight, durable kids’ bike built for off-road adventures. Its robust aluminium frame offers easy handling as young riders navigate trails, while being tough enough to endure rough terrain. The 9-speed 1x drivetrain provides a range of gears for climbing steep trails, and the disc brakes deliver superior stopping power, allowing for quick, precise braking. Ideal for riders between 114 and 132 cm tall, it’s the perfect companion for trail exploration.
