Meet the new Seeker X20

The Seeker X20 is a high-performance 20" hardtail mountain bike designed for riders aged 6–8 who are eager to take their trail adventures to the next level. Featuring 100mm RST F1RST air suspension forks and a lightweight frame optimized for trail riding, this bike delivers excellent handling, comfort, and confidence on challenging terrain. Its sealed-bearing wheels with bolt-thru axles provide durability and smooth rolling performance, while Schwalbe Smart Sam 2.35" tires offer exceptional traction on a variety of surfaces. A refined chain-driven system combines a new 110mm crankset with a Shimano CUES 9-speed drivetrain, maximizing pedaling efficiency and making the Seeker X20 an ideal companion for aspiring young trail riders.

A performance optimised aluminium frame

Engineered with performance in mind, the Seeker X20 features a butted aluminium frame built to handle tough impacts while maintaining a lightweight feel.

The tubing is strategically shaped to provide reinforcement where strength is most needed while minimizing excess material elsewhere, creating an efficient balance between durability and weight. Threaded thru-axles enhance frame rigidity, while sliding dropouts allow for geometry and fit adjustments as young riders grow. Internal cable routing keeps the frame clean and protected, and the bike comes ready for dropper post installation.

Long, low and slack

Exactly as it should be.

The Seeker X20's geometry is purpose-built for speed, control, and confidence on technical trails.

A low center of gravity helps maintain stability through corners and berms, while the slack head angle improves confidence and composure on descents. Short chainstays contribute to a playful, agile ride quality and make front-wheel lifts and manuals easier to learn.

A no fuss, full gas chainset

The crankset and single-chainring configuration deliver an impressive combination of performance, safety, and pedaling efficiency rarely found on bikes of this size.

A narrow-wide chainring helps keep the chain secure by reducing movement and preventing drops, while the 110mm cranks promote efficient power transfer. The single-ring setup also reduces overall weight and simplifies operation, allowing young riders to stay focused on the trail ahead.

Anatomically designed cockpit

Designed specifically to support rider development and control, the cockpit offers an ergonomic fit that improves steering accuracy and overall handling.

Lock-on grips provide a secure hold, helping prevent hand slippage during wet and muddy rides.

Big kid forks, little kid bike

The Seeker X20 is equipped with 100mm RST F1RST suspension forks that deliver serious performance in a youth-sized package.

Offering adjustment features typically found on larger bikes, these forks are built to handle rough trails and demanding riding conditions. Riders can fine-tune air pressure, compression, and rebound settings to match their skill level, terrain, and weight, ensuring an optimized riding experience.

Lightweight, adjustable brakes

Tektro Hydraulic Disc Brakes provide dependable stopping power, smooth modulation, and a lightweight design, making them a standout choice for young riders.

Their predictable braking feel allows for controlled speed management without abrupt stops, while the 160mm six-bolt rotors provide strong and reliable braking performance when it matters most.

A Shimano CUES drivetrain

The Shimano CUES 1x9 drivetrain offers a dependable blend of durability, efficiency, and simplicity.

Its low-maintenance design helps reduce weight without compromising performance. Smooth operation, precise gear changes, rugged construction, and reliable performance make Shimano CUES a trusted drivetrain choice for riders of all levels.

MTB wheels that go hard

Built for demanding trail use, the wheelset features fully sealed bearing hubs, double-wall rims, and an optimized spoke configuration, paired with highly grippy Schwalbe Smart Sam tires.

Strong wheels are essential to a capable mountain bike, and these are designed to perform. Sealed bearings help protect against mud, water, and corrosion, while double-wall rims provide added durability when tackling rocks and roots. The optimized spoke count enhances wheel strength and reliability, and thru-axles make tire changes and maintenance quick and straightforward.
