Trek Wahoo 26

When you step back and look at the kid's bikes, they all start to look the same: Heavy frames, heavily treaded tires and a clumsy suspension fork that isn't really needed most of the time. Trek's Wahoo is different approach to those first long bike rides beyond the neighborhood. A lightweight Alpha Silver aluminum frame helps to keep your little shredder feeling less tired on hot summer days. Instead of deeply-treaded monster-truck tires, the Wahoo sports low-profile rubber to help keep their momentum. A single 8-speed Shimano trigger shifter control a rear Shimano derailleur, simplifying gear changes. a 11-34T rear Shimano cassette boasts a wide gearing range for hilly trails (and that last climb when riding to school). Linear-pull brakes help keep speed in check. A bottle cage mount and rear rack mounts on the frame show that Trek left nothing off when building a bike for the next cycling generation.

The size chart says "Fit for riders 53-66 inches tall", but come in for a test ride just to be sure.
