City, mountains, and travel. A "modern ATB" that lets you enjoy it all.

The KONA UNIT X is a rare modern mountain bike that is "simple and can do everything."

Its chromoly full-rigid frame and 29x2.6 tires may seem classic at first glance. But once you ride it, you'll be surprised by the balance of its agility and off-road capability.

It's not just for attacking mountains. It's also fun to cruise around town, and you can load it up and go on a trip. Furthermore, its high expandability, allowing for single-speed conversion and dropper post installation, is also attractive.

It's the perfect "modern ATB" for those who want to "play with everything on one bike."

Not just fast, but a ride that reminds you of "all the fun"

Simple, yet incredibly fun

A chromoly full-rigid frame without suspension, and large 29x2.6 tires. The configuration is very simple, but that's what makes the UNIT X so interesting – you can feel the road surface and terrain directly.

While incorporating modern geometry, it achieves an exquisite balance that doesn't lean too heavily towards downhill performance, resulting in natural handling that feels at home even in the city.

A raw trail feel only rigid bikes can offer

An MTB that lets you feel the terrain with its tires and your body

MAXXIS RECON 29x2.6 tires and tubeless-ready specifications provide a surprising sense of security for a rigid bike.

The sensation of traversing tree roots and treading on soil offers a different kind of appeal than a full-suspension bike. Coupled with the wide gear range of SHIMANO DEORE 12-speed, it's a reliable setup for both climbing and touring.

Flexible for loading and customizing. Expandability that doesn't limit how you play.

Supports both touring setup and single-speed conversion

In addition to the frame's various braze-ons, the slider dropout allows for adjusting both loading style and ride feel.

You can shorten the rear center for a playful ride or extend it for stability. It also supports single-speed conversion and dropper post installation, offering the freedom to decide "how to ride" – a unique feature of the UNIT X.

An all-around MTB that expands "what to play" with

The KONA UNIT X is not just a trail bike.

It's a bike that accompanies you on days cruising the city, days embarking on a journey with luggage, and days spontaneously heading into the mountains – all in one package.

It's the kind of bike that reminds you of "the pure joy of cycling itself," distinct from the high-spec competition.

For those who want to enjoy MTBs more freely without overthinking them, the UNIT X is a truly special option.
