We've broken the mould with our kid’s bikes. By putting 26" wheels on a kids MTB we've given a boost in performance similar to an adult switching to a 650b/27.5" Trail Hardtail. More confidence, more control & easier riding. For 2018 Whyte has speced a trigger shifter, which will help with the transition to an adult bike. The 403 also comes with Whyte's own Get-a-Grip seat post clamping system. This easy to use clamp allows the post to be raised or lowered on the trail, even with small cold hands.
