We’ve downsized everything except the performance so you can start them right with a Whyte.

Our 405 set a whole new standard for junior MTB performance and the new 403 makes the gift of a truly great kids bike more affordable.

A specific lightweight tubeset - not just sawn off versions of adult pipes - shrinks climbs and puts a tailwind into every ride. We’ve downsized our maximum confidence Trail geometry and fitted air sprung forks that properly work for lighter pilots so their rides are full of thrills not spills. SRAM NX or Shimano single ring transmissions gives simple, instinctive, sequential shifts but still have the gears for every climb and a chainset sized for shorter legs.

We’ve even stripped down the spoke count on the 26in wheels and fitted the same grippy front, fast rear tyre combinations as our full sized trail bikes, so they’re fast and fun, and make every adventure easier.

Expanding horizons even further, we’ve also introduced two of our award-winning, benchmark-setting Trail suspension bikes, the T-130 SR and T-130 S, to the Youth collection by making them available in XS size.

"The excellent Whyte 403 offers a ‘grown up’ ride while serving up lashings of confidence, reliability and above all fun to the most important mini-shredder in your life" Enduro Mountain Bike Magazine

More Confidence, More Control

We've broken the mould with our kids 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 and easier riding.

Trigger Shifter

For the new 403 Whyte has specced a trigger shifter, which will help with the transition to an adult bike.

Get-a-Grip

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.

 
it’s a bike we all wish we had owned as a kid
