Questions people ask about the DYU C3
How much does it weigh?
The DYU C3 weighs 39.9 kg. That is 52% above the median weight for folding e-bikes, which is 26.3 kg. This is a heavy bike, so consider how you will carry it.
How much torque does it have?
The motor delivers 30 Nm of torque. That is 25% below the median torque of 40 Nm for its type. It is a hub motor, so it will assist you but not give you strong hill-climbing power.
What speed class is it?
It is a standard pedelec class, with a top speed of 24 km/h. That means it assists you while you pedal, up to that speed. It has no throttle.
How far does it really go?
The manufacturer claims a range of 40 km. Our estimate is 25 km, with a band of 22 to 28 km. That estimate is 38% below the claim. The estimate is based on a reference ride, not a test. Use the range calculator to adjust for your conditions.
What does it cost to run?
The purchase price is 499 USD, which is 50% below the median of 999 USD. Running costs depend on electricity and maintenance. The warranty is not listed, so you cannot rely on published coverage. Use the cost calculator to compare long-term costs.
Where it falls short
The DYU C3 makes clear compromises to hit its low price. The battery is 48% below the median capacity, and the estimated range is 49% below the median. The weight is 52% above the median, making it hard to carry or maneuver when folded.
Who should buy it
The DYU C3 is a budget folding bike for riders who value low upfront cost above all else. It fits a specific niche: short commutes, flat terrain, and minimal carrying needs.
- You want the cheapest folding e-bike available, and you accept the low range.
- Your commute is under 10 km each way, and you can charge at work.
- You have a place to store it where you do not need to lift it often.
Look elsewhere if you need a bike that can handle hills, long distances, or frequent folding. The heavy weight and low torque will frustrate you. Consider a bike with a larger battery and lighter frame, even if it costs more.
