How does the Aairsk GT900 Full Suspension Electric Bike battery work?

The GT900 uses a 36V 13Ah, 468Wh battery integrated into the frame. Manufacturer material has described removal differently across versions, so confirm whether the exact TrailSurge unit is intended for routine off-bike charging before ordering. Use the supplied charger and allow roughly 5–6 hours from low, with the bike or battery kept dry and ventilated.

What is the difference between the Aairsk GT900 and Unibike Aairsk Q7 Electric Bikes?

The GT900 has the larger 36V 13Ah battery, 21-speed gearing and a more comfort-focused suspension setup. The Q7 uses a smaller 36V 10Ah battery, seven gears and 26 × 2.6-inch tyres for a simpler mixed-surface package. Choose the GT900 for gearing range and energy capacity, or the Q7 for straightforward everyday use.

How should I maintain the Aairsk GT900 Full Suspension Electric Bike?

Check suspension fasteners for play, keep the 21-speed drivetrain clean and verify that all front and rear gears shift without chain rub. Inspect mechanical disc-brake pads, cable tension, rotor alignment, tyre pressure and spoke tension regularly. Use only GT900-compatible electrical parts because displays, controllers and connectors can look similar across Aairsk models.

Is the Aairsk GT900 Full Suspension Electric Bike easy to assemble?

The Aairsk GT900 Full Suspension Electric Bike arrives mostly assembled. Final setup normally includes aligning and securing the handlebars, fitting the pedals and completing essential safety checks. Allow approximately 20–30 minutes, or select our professional assembly and PDI service.

Is the Aairsk GT900 Full Suspension Electric Bike water resistant?

The Aairsk GT900 Full Suspension Electric Bike is not fully waterproof. Avoid prolonged exposure to heavy rain, and never submerge or pressure wash the bike or its electrical components. After riding in wet conditions, wipe the bike dry and store it in a dry, sheltered location.

Description

The Aairsk GT900 full suspension electric bike brings added comfort to outdoor cycling. With front and rear suspension, 26-inch wheels and Shimano 21-speed gearing, it's designed for riders who enjoy recreational routes where the surface and gradient can change.

Key Features

Front and rear suspension to soften bumps on uneven ground.
26-inch mountain-bike wheels for familiar handling.
Shimano 21-speed gearing for a wide choice of pedalling ratios.
36V 13Ah battery to support assisted rides.
Mechanical disc brakes, LCD display and NFC activation for practical control.

Extra Comfort on Changing Surfaces

Unlike a front-suspension-only design, the GT900 features suspension at both ends of the bike. This helps reduce the harshness of bumps on suitable trails and provides a more forgiving feel during relaxed outdoor adventures.

More Gears for More Flexibility

The 21-speed gear system gives you plenty of options when pedalling uphill or along flatter sections, while the electric system adds assistance when required. For riders looking for a 26-inch full suspension electric mountain bike, the GT900 combines familiar controls with a comfort-focused setup.
