What riders ask about the AAIRSK GT900
How much does it weigh?
The GT900 weighs 25.9 kg. That is 24% below the median weight for e-MTBs, which is 34.2 kg. A lighter bike is easier to handle off-road or when carrying it up stairs.
How much torque does it have?
The motor torque is listed as 0 Nm. That is unusual, and it may mean the manufacturer does not publish a torque figure. The median torque for e-MTBs is 80 Nm, so this bike likely has less climbing power.
What speed class is it?
It is a standard pedelec class, with a top speed of 25 km/h. That means the motor assists up to 25 km/h, and you must pedal to get assistance. It has no throttle.
How far does it really go?
The manufacturer claims a range of 69 km. MathBikes estimates the range at 27 km, with a band of 24 to 30 km. That estimate is 61% below the claim. The estimate comes from a formula, not a test ride.
You can adjust the assumptions with the range calculator. Your real range depends on your weight, terrain, and assist level.
What does it cost to run?
The purchase price is 755 USD. Running costs include electricity for charging and maintenance. The battery is small, so charging is cheap, but you may need to replace it sooner if you ride often. Use the cost calculator to compare long-term costs.
Where it falls short
The GT900 has a small battery and a low estimated range. Its 468 Wh battery is 44% below the median of 840 Wh. The estimated range of 27 km is 45% below the median of 49 km. That means you will need to charge often, even on short rides.
Who should buy it
The AAIRSK GT900 is for budget-conscious riders who want an e-bike for short trips. It is light and inexpensive, but it is not built for long-distance or high-torque riding.
- You ride less than 25 km per trip and can charge at home or work.
- You want a light e-MTB for gentle trails or paved paths.
- You are buying your first e-bike and want to keep the cost low.
Look elsewhere if you need a long range or strong hill-climbing power. The GT900's 0 Nm torque and 27 km estimated range will frustrate you on steep or long rides.
