Questions people ask about the DYU King 750
How much does it weigh?

How much torque does it have?

How far does it really go?

Where it falls short
The King 750 gives up torque and carries extra weight. Its 60 Nm motor is below average for mountain e-bikes. The 35.8 kg frame is heavy. You trade climbing punch and handling for battery capacity and price.
Who should buy it
This bike fits riders who value range and speed over light weight. It is for those who ride mostly flat or rolling terrain. It is also for budget-conscious buyers who want a large battery.
- You want a long estimated range of 55 km, well above the class median of 42 km.
- You want a top speed of 45 km/h for faster commutes.
- You want a price below the median for its type.
Look elsewhere if you need strong hill-climbing torque or a light bike. The 60 Nm motor and 35.8 kg weight will not suit everyone. If you plan to carry heavy loads, note the max payload is 150 kg, but the bike is not cargo-rated.
