The Alpha Silver Aluminium frame keeps the Wahoo 20 Trail both lightweight and robust, making it easier for kids to handle while standing up to the bumps and scrapes of regular use. Its carbon fork helps reduce weight further and provides precise steering for more confident control.
With a microSHIFT Advent 9-speed drivetrain, the Wahoo 20 Trail offers young riders a wide range of gears, making climbs easier and giving them the ability to keep up speed on the flats. The Tektro hydraulic disc brakes ensure reliable stopping power in all weather conditions, offering parents peace of mind when it comes to safety.
The 20” wheels are fitted with Kenda Amrak tyres, designed for grip and stability on a variety of surfaces, from woodland paths to gravel tracks. Trek’s ThruSkew system adds security and simplicity to wheel fitting and removal, providing an extra layer of reassurance compared to standard quick-release skewers.
Perfect for riders between 114–132cm tall, the Trek Wahoo 20 Trail gives kids the tools they need to develop their riding skills and enjoy more challenging adventures. It’s a thoughtfully designed, trail-ready junior bike that makes every ride both fun and confidence-building.
