Questions people ask about the Koolux X11
How much does it weigh?
The X11 weighs 36.3 kg. That is 27% above the median for folding e-bikes. You will feel the extra weight when lifting or carrying it.
How much torque does it have?
The motor torque is listed as 0 Nm. That is not comparable to the class median of 50 Nm. MathBikes does not estimate torque, so we cannot say more.
What speed class is it?
The X11 is a standard pedelec class. Its top speed is 25 km/h. It has no throttle, so you must pedal to get assistance.
How far does it really go?
The manufacturer claims 150 km. MathBikes estimates 80 km, which is 47% below that claim. The estimate comes from a formula, not a test. You can see how it works with the range calculator.
What does it cost to run?
The X11 costs 1284 USD. That is 20% above the median for its type. Running costs depend on electricity and maintenance, which are not listed. You can estimate them with the cost calculator.
Where it falls short
The X11 is heavy. At 36.3 kg, it is 27% above the median for folding bikes. That weight makes it harder to carry upstairs or onto a train. It also has no torque listed, which may mean the motor is weak.
Who should buy it
The X11 is for riders who want maximum range from a folding bike. Its large battery gives an estimated 80 km, which is 67% above the median. It is not for riders who need a light bike.
- You commute long distances and need a folding bike for the last mile.
- You have a place to store a heavy bike and rarely carry it.
- You value battery capacity over portability and price.
Look elsewhere if you need a bike you can lift easily. The X11 is 36.3 kg, so it is not a good choice for stairs or public transport. Also, if you want strong acceleration, the lack of torque data is a warning.
