The Wahoo 20 is a lightweight, simple, and convenient children's hybrid bike that gives your child the ability to get the most out of every ride. This versatile bike has been designed with ease of use in mind: it is lightweight, capable of riding on different surfaces and equipped with an 8-speed single-chainwheel transmission and a wide gear range to accompany your child everywhere. For children aged 6 to 8 and measuring 114 to 132 cm .

A lightweight Alpha Aluminum frame that kids can lift and maneuver with ease, multi-surface tires that provide grip on different terrains, and an 8-speed single-chainring drivetrain that makes shifting easy so kids can focus on the essentials : enjoy.


The + product:

  • Lightweight and Capable: The Wahoo's aluminum frame is strong and durable, yet light enough for kids to easily master.
  • Lugs closed with Trek's exclusive ThruSkew system, a safety system that prevents accidental detachment of the wheels.
  • The 8-speed single-chainwheel drivetrain makes shifting easy, so kids can think of only one thing: having fun.
  • Avoid buying your child's bike where you buy your cereal. Unlike what happens in big box stores, Trek kids' bikes are put together by people who know the bike.
