City, Mountains, Travel, all in one: The UNIT X Choice

A full chromoly rigid frame without suspension, and 29x2.6 inch semi-fat tires.
The configuration is surprisingly simple, but because of that, the information from the ground is direct and incredibly fun.

The UNIT X is more of an All Terrain Bike than a "Mountain Bike," meaning a bike that can go anywhere.
It's a bike that still cherishes "something" that modern MTBs lost in exchange for downhill performance.

The neutral geometry with a 68-degree head angle feels natural in the city and provides a sense of security on dirt.
That's why you can purely enjoy riding, regardless of the location.

Reasons to Play Hard Even with a Rigid Setup

"You can't ride trails without suspension." The UNIT X easily overturns such preconceptions.

The MAXXIS RECON 29×2.6 tires absorb shocks with a micro-suspension effect from their air volume.
It's also a welcome feature that they are tubeless-ready from the start, combined with WTB ST rims.

The drivetrain uses SHIMANO DEORE 1x12 speed.
It firmly covers a wide range of situations, from the light gears desired on trails to the 10T top gear useful on paved roads.

It's not a bike for aggressive downhill riding, but you can directly enjoy the sensation of the tires gripping the dirt and overcoming roots.
Trail riding can be freer, and that's the riding experience it offers.

Expandability for Cargo, Singlespeed, and Dropper Post

One of the biggest appeals of the UNIT X is its overwhelming expandability.

With eyelets provided on various parts of the frame and fork, it flexibly supports panniers and bikepacking.
Handling remains stable even when loaded, showing its versatility for going straight onto dirt trails.

The slider dropouts allow for rear center adjustment and singlespeed conversion.

Furthermore, it supports internal dropper posts, allowing for customizable setups that are easy to handle on both trails and city rides.

A complete bike where "how you use it" is up to you.
That's what the UNIT X is.

Summary | Why the UNIT X is Called 'The Strongest'

Neutral geometry that's not overdone, and a Reynolds 520 chromoly frame
29x2.6 tires and DEORE 1x12 speed for serious off-road fun, even with a rigid setup
High expandability for cargo, singlespeed conversion, and dropper post compatibility
A modern ATB that can handle city, mountains, and travel all in one
Its high degree of freedom makes it the "strongest" choice among complete bikes

Speed, efficiency, numerical superiority. Mountain bikes have increasingly been discussed in such terms.

But bicycles were originally more innocent, freer vehicles, weren't they?

Riding without a destination, turning into interesting side roads, continuing onto dirt when the pavement ends, loading up luggage and going further.

The UNIT X is a bike that truly embodies the "feeling of riding a bicycle for the first time" in a modern complete package. A chromoly full rigid frame with large 29x2.6 tires.

It lacks flashy mechanisms, which is precisely why it keeps you closer to the ground and makes riding itself enjoyable. You don't need to change your riding style for the city, mountains, or travel. Just follow your mood.

Commuting today, trails on the weekend, then loading up your gear and heading to unknown roads...

The UNIT X doesn't negate any of these uses. It offers time to laugh and ride with childlike glee, spinning those big tires. The UNIT X is a monster machine that will be a long-term companion for anyone who wants to make cycling a "hobby" in their life.
