Questions people ask
How much does it weigh?
The Koolux X16 weighs 30.8 kg. That is 8% above the median for folding e-bikes. You will feel the weight when carrying it up stairs. Folding helps, but the bike is still heavy.
How much torque does it have?
The motor torque is listed as 0 Nm. That figure is not comparable to other bikes. The motor type is hub, but torque is not published. If torque matters to you, check with the manufacturer.
What speed class is it?
It is a standard pedelec class. Top speed is 25 km/h. That means the motor assists up to 25 km/h. You can go faster downhill, but the motor stops helping.
How far does it really go?
The manufacturer claims 113 km. MathBikes estimates 54 km, with a band from 47 to 60 km. That estimate is 52% below the claim. The estimate comes from the range calculator, which uses a standard reference ride. It is not a measurement.
What does it cost to run?
The purchase price is 852 USD. Running costs depend on electricity and maintenance. Use the cost calculator to compare. The warranty is not listed, so budget for potential repairs.
Where it falls short
The Koolux X16 has no torque, which means weak hill climbing. The motor torque is 0 Nm, so it may struggle on steep slopes. The bike is also heavy at 30.8 kg. That weight makes it less agile and harder to carry.
Who should buy it
This bike fits riders who want a low-cost folding e-bike with a large battery. It is best for flat routes and short commutes. The 749 Wh battery gives you a range above the median. The price is below the median, so you get more for less.
- You need a folding bike for mixed commutes, like train and road.
- You ride on flat terrain and do not need high torque.
- You want a large battery for longer trips between charges.
Look elsewhere if you live in a hilly area. The 0 Nm torque will not cut it. Also, if you need to carry the bike often, the 30.8 kg weight is a problem. Consider a lighter model, even if it costs more.
