What riders ask about the YINYU14
How much does it weigh?
The YINYU14 weighs 20 kg. That is lighter than most folding e-bikes, which average 28.6 kg. You can carry it up stairs, but 20 kg is still a solid lift.
How much torque does it have?
The hub motor delivers 35 Nm of torque. That is 30% below the class median of 50 Nm. Expect modest acceleration and limited hill-climbing power.
What speed class is it?
It is a standard pedelec class. The motor assists up to 25 km/h. There is no throttle, so you pedal to move.
How far does it really go?
The manufacturer claims 25 km. MathBikes estimates 27 km, based on a standard reference ride. That estimate is 8% below the claim. Real range depends on your weight, terrain, and assist level.
The estimated range is 44% below the class median of 48 km. This bike suits short commutes or errands, not long tours. Use the range calculator to see how it performs under different conditions.
What does it cost to run?
The purchase price is 474 USD. Running costs depend on electricity, maintenance, and replacement parts. The battery is 374 Wh, which is small, so charging is cheap. But the warranty is not listed, so factor in potential repair costs.

Where it falls short
The YINYU14 makes clear trade-offs to hit its low price. The battery is 44% smaller than the class median, and the motor torque is 30% lower. That means short range and weak hill performance.
Who should buy it
The YINYU14 is for budget-conscious riders who make short, flat trips. It is light enough to carry onto a train or up stairs. It is not for heavy riders or long-distance commuters.
- You want an affordable e-bike for rides under 25 km.
- You need a light folding bike for mixed commuting.
- You ride on flat terrain and do not need much torque.
Look elsewhere if you need a long range, strong hill climbing, or a high payload. The max payload is 100 kg, which includes the rider and cargo. This bike is not cargo capable and has no step-through frame.
