Questions people ask about the AAIRSK XT90 Emtb
How much does it weigh?
The AAIRSK XT90 Emtb weighs 29.1 kg. That is 15% below the median weight for mountain e-bikes, which is 34.2 kg. It is not the lightest e-bike you can find, but it is lighter than many in its class.
How much torque does it have?
The motor delivers 75 Nm of torque. That is 6% below the median torque for its type, which is 80 Nm. For steep climbs, you might want more torque, but it is adequate for most trails.
What speed class is it?

How far does it really go?

What does it cost to run?
The purchase price is 971 USD, which is 38% below the median for its type. Running costs depend on electricity and maintenance. Use the cost calculator to estimate your own costs. The warranty is not listed, so factor that into your decision.
Where it falls short
The AAIRSK XT90 Emtb has a hub motor, not a mid-drive. Hub motors can feel less natural on technical trails. The torque is 75 Nm, which is below the median of 80 Nm. Also, the maximum payload is not listed, so you do not know the official load limit.
Who should buy it
This bike is for riders who prioritize battery capacity and value. It offers a 960 Wh battery at a price well below the median. It is also lighter than average, which helps with handling.
- You want a long estimated range of 55 km for longer rides.
- You want a mountain e-bike that costs less than the median price of 1554 USD.
- You prefer a lighter frame, at 29.1 kg, compared to the median of 34.2 kg.
Look elsewhere if you need high torque for steep climbs or if you require a throttle. This bike has no throttle. Also, if you need a foldable or step-through frame, this is not it.
