AAIRSK GT900 Full-Suspension Electric Mountain Bike

Built for Comfort and Mixed-Terrain Riding

The AAIRSK GT900 is a full suspension electric mountain bike designed for everyday roads, gravel paths and light recreational trails.

Available with 24″ or 26″ wheels, the GT900 combines a 250W rear hub motor, front and rear suspension, Shimano 21-speed gearing and mechanical disc brakes for riders who want greater comfort and flexibility across changing road surfaces.

250W Rear Hub Motor

The EU/UK GT900 configuration uses a 36V 250W rear hub motor with electric assistance limited to 25 km/h (15.5 mph).

The GT900 also has fully functional pedals, allowing it to be ridden as a conventional bicycle when electric assistance is not required.

Full Suspension

A lockout front suspension fork works together with multi-link rear suspension to help reduce vibration over uneven roads and gravel surfaces.

This makes the GT900 well suited to everyday riding, park routes and light recreational trails without positioning it as an extreme downhill or professional off-road bike.

Shimano 21-Speed Gearing

The GT900 features a Shimano 21-speed drivetrain (3×7), giving riders more flexibility when adapting to flat roads, gradual climbs and changing terrain.

13Ah Battery

The GT900 is supplied with a 13Ah battery specification for everyday and mixed-terrain riding. Battery performance and riding distance can vary depending on rider weight, terrain, temperature, speed, riding mode and other conditions.

Up to 52 km Estimated Riding Range

The GT900 offers an estimated riding range of up to 52 km under suitable riding conditions.

Actual range may vary, so the 52 km figure should be treated as an up-to estimate rather than a guaranteed distance.

24″ and 26″ Wheel Options

The GT900 is available in two sizes:

24″: generally suited to riders around 155–170 cm

26″: generally suited to riders around 165–185 cm

The 24″ version provides a more compact riding setup, while the 26″ version offers a more traditional full-size riding feel. Individual fit may vary.

Mechanical Disc Brakes

Front and rear mechanical disc brakes provide controlled everyday braking across normal roads and mixed riding surfaces.

Braking performance may vary depending on weather, road conditions, tyre condition and brake adjustment.

LCD Display with NFC

The GT900 features an LCD display with NFC functionality, allowing riders to view key riding information and use the bike's supported NFC access function.

Mostly Pre-Assembled

The GT900 arrives mostly pre-assembled, with only a limited number of final components normally requiring installation or adjustment before riding.

Always follow the supplied instructions and complete basic safety checks before the first ride.

Warranty and After-Sales Support

The GT900 includes a 2-year warranty for the frame and 1-year coverage for the battery, motor, controller and other eligible original components, subject to the AAIRSK Warranty Policy.

AAIRSK also provides after-sales assistance and compatible replacement parts for supported models.

Who Is the GT900 For?

The GT900 is a good fit for riders who want more suspension comfort and wider gearing than a basic commuter e-bike.

Its combination of full suspension, 21-speed gearing and two wheel-size options makes it suitable for commuting, leisure riding, uneven roads, gravel paths and light recreational trails.
