Questions people ask about the DYU C3 14
How much does it weigh?
The DYU C3 14 weighs 20.4 kg. That is lighter than most folding e-bikes, which average 28.6 kg. You can fold it, but the manufacturer does not publish a folded size.
How much torque does it have?
The motor torque is listed as 0 Nm. That is not a real figure. It means the manufacturer does not publish torque for this bike. The median for its type is 50 Nm, but you cannot compare without a published number.
What speed class is it?
It is a standard pedelec class. That means the motor assists up to 25 km/h. There is no throttle on this bike.
How far does it really go?
The manufacturer claims a range of 34 km. MathBikes estimates 20 km, with a band of 17 to 22 km. That estimate is 41% below the 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 purchase price is 403 USD. Running costs depend on electricity and maintenance. The battery is small, so charging it costs little. Use the cost calculator to compare long-term costs.
Where it falls short
The DYU C3 14 has a small battery. At 270 Wh, it is 60% below the class median of 672 Wh. That directly cuts the estimated range to 20 km, which is 58% below the median of 48 km.
Who should buy it
This bike is for short, flat trips where you value low cost and light weight. It is not for long commutes or carrying cargo. The manufacturer does not publish a max payload, so do not assume it can carry heavy loads.
- You ride less than 17 km per trip and can charge at work or home.
- You need a light folder to carry onto public transport.
- You want the lowest possible entry price for an e-bike.
Look elsewhere if you need more range or a higher payload. The DYU C3 14 is a niche product. It fits a specific budget and distance, and it does that well.
