The AAIRSK F6 is a folding e-bike with a 576 Wh battery. That capacity sits 14% below the median for its type, which is 672 Wh. It weighs 23.5 kg, which is 19% below the median of 29 kg. The low weight is the number that most sets it apart from other folding e-bikes.
You get a 250 W rated motor and a 48 V system. The battery holds 12 Ah. MathBikes estimates a range of 42 km, with a band of 37 to 47 km. The maker claims 52 km, so the estimate is 19% below the claim. At 615 USD, the price is 41% below the median of 1049 USD.

Questions people ask about the AAIRSK F6
How much does it weigh?
It weighs 23.5 kg. That is 19% below the median for folding e-bikes, which is 29 kg. For a folding bike, that matters when you lift it into a car or carry it up steps. It is still a heavy object, so test your own lift before you buy.
How much torque does it have?
The torque is not published. The median for this type is 50 Nm, but you cannot compare the F6 to that figure because the maker does not list a torque value. If torque matters to you, ask the seller for it in writing. Without it, you cannot judge hill climbing from the spec sheet.
What speed class is it?
The speed class is not published. The top speed is not published either. That means you cannot tell from the listing whether it is limited to a lower assist speed or a higher one. Check the local rules where you ride before you buy.
How far does it really go?
MathBikes estimates 42 km, with a band of 37 to 47 km. The maker claims 52 km, so the estimate is 19% below the claim. The estimate uses one reference ride for every bike on the site: Tour assist, rolling terrain, mild weather, brisk pace and an 80 kg rider. It is not a measurement. You can run your own numbers with the range calculator.
What does it cost to run?
The battery holds 576 Wh, or 12 Ah at 48 V. Charging cost depends on your electricity price, which is not part of this brief. The purchase price is 615 USD, which is 41% below the median of 1049 USD. Use the cost calculator to add your own power price.
Where it falls short
The F6 gives up battery capacity and range to hit its price and weight. Its 576 Wh battery is 14% below the median of 672 Wh. Its estimated range of 42 km is 12% below the median of 48 km. The maker's claim of 52 km is 19% above the estimate, so plan around the lower figure. Torque, top speed, speed class and warranty are all not published, which leaves real gaps in the spec sheet.
Who should buy it
Buy the F6 if low weight and low price matter more to you than range. It folds, so it suits mixed trips with a car, train or bus. The 150 kg maximum payload is generous for a folding bike. Just accept the smaller battery and the missing torque, speed and warranty figures.
- You fold and lift the bike often, and 23.5 kg is easier to handle than the 29 kg median.
- You want a low entry price, and 615 USD is 41% below the 1049 USD median.
- You ride short trips where 42 km estimated range is enough, and you can charge often.
Look elsewhere if you need long range, strong climbing or full published specs. The 576 Wh battery and 42 km estimate will not suit all-day rides. The missing torque and speed class figures make it hard to compare on performance. If those matter, choose a bike with a larger battery and a complete spec sheet.
