Meet the new Seeker X20

The Seeker X20 is a premium 20" hardtail bike built for young riders aged 6–8 who are ready to push their trail riding further. Equipped with 100mm RST F1RST air suspension forks and a lightweight, trail-optimized frame that is dropper post ready. The Seeker X20 offers outstanding control, comfort, and confidence on rough terrain. Sealed bearing wheels with bolt-thru axles deliver strength and smooth, consistent rolling, while wide Schwalbe Smart Sam 2.35" tires ensure superior grip across mixed surfaces. The refined chain-driven drivetrain features a new 110mm chainset and a Shimano CUES 9 Speed drivetrain for improved pedal efficiency. Making the Seeker X20 the perfect choice for ambitious young trail riders.

The full story

A performance optimised aluminium frame

Built for performance, the Seeker X20 features a butted aluminium frameset that’s precision engineered to absorb big hits like a champ.
The frame tubing has been deliberately crafted to balance strength (at the pressure points) with lightness (everywhere else), to ensure we don’t add unnecessary weight or hinder progress.
Threaded thru axles ramp up frame stiffness while sliding dropouts enable handing and size tweaks as little riders progress.
The Seeker X20 features internal cabling and comes dropper post ready, making installation of your preferred post a dream.

Long, low and slack

That’s the assignment and we understood it.

The Seeker X20 is built for performance with a geometry optimised for speed, technical acumen and confidence on the gnarly bits.

The low centre of gravity keeps them balanced in the berms while the slack head tube angle takes (some of the drama) out of descending. The short seat stays give the bike a playful responsive feel (while also making manuals just a little easier to master).

A no fuss, full gas chainset

The crankset and single ring set-up give the Seeker X20 an awesome mix of performance, safety and pedalling efficiency that you simply won’t find on other bikes this size.

The narrow wide chain ring stops the chain from flapping and slipping and works in harmony with 110mm cranks for pedalling efficiency.

The single ring set up saves weight while allowing progressive young riders to focus fully on the trail.

Anatomically designed cockpit

The cockpit is anatomically designed for progression and control. When everything fits right, steering becomes more precise, more controlled. The lock on grips prevent hand slip in the inevitable wet muddy conditions.

Big kid forks, little kid bike

The Seeker X20 comes equipped with 100mm of smash proof front suspension courtesy of RST F1RST. Featuring the same levels of adjustability typically found on much bigger kids’ bikes, the Seeker X20 can withstand pretty much anything little rippers decide to throw at it.

Fine tune the float with adjustable air suspension, compression and rebound to dial in their ride according to the demands of their skill set, terrain or current weight.

Lightweight, adjustable brakes

Featuring a lightweight, smooth modulation, plenty of adjustability and ultra reliable braking, it’s no wonder we’re such big fans of Tektro Hydraulic Disc Brakes

Braking feedback is predictable with a smooth modulation that prevents unnecessary emergency stops while the 160mm 6 bolt rotors give bold riders the confidence they need to go hard, and stop harder.

A SRAM GX drivetrain

The Shimano CUEs 1x9 drivetrain is a robust, efficient, and versatile drivetrain that balances simplicity with performance. The low-maintenance setup which saves valuable weight without sacrificing performance. With its smooth, light action, accurate shifting, superior weight and robust build, there’s a reason why Shimano CUEs is the drivetrain of choice for so many riders.

MTB wheels that go hard

Fully sealed bearing hubs, double wall rims and optimised spoke count, wrapped in Schwalbe super grippy Smart Sam tires means these wheels are ready to rip.

Because there’s no point spec'ing a great bike with weak wheels.

Sealed bearings keep mud, water and corrosion at bay while double wall rims give you twice the confidence on rocks and roots.

The optimised spoke count means you won’t have to worry about buckled wheels while thru axles makes the rare times you do need to swap tyres a breeze.
