Questions people ask about the DYU FF500
How much does it weigh?
The FF500 weighs 18.1 kg. That is light for an e-mtb. The median weight for its type is 28.1 kg. You can lift it more easily, but it is not a lightweight acoustic bike.
How much torque does it have?
The motor delivers 86 Nm of torque. That is 8% above the median of 80 Nm. It is a hub motor, so the torque feels different from a mid-drive. It should handle hills, but not like a mid-drive.
What speed class is it?
It is a fast-class e-bike. Assist goes above 25 km/h. The top speed is 45 km/h. That means it is not a standard pedelec. Check local rules before you ride.
How far does it really go?
The manufacturer claims 72 km. MathBikes estimates 57 km. That is 21% below the claim. The estimate comes from a formula, not a test. Use the range calculator to adjust for your own conditions.
What does it cost to run?
The price is 1999 USD. That is 5% above the median of 1899 USD. Running costs depend on electricity and maintenance. The warranty is not listed. You can compare costs with the cost calculator.
Where it falls short
The FF500 is a fast bike, but it has no throttle. You must pedal to get assist. It is also not cargo capable. The max payload is 150 kg, which is fine for one rider and gear. But you cannot carry heavy loads.
Who should buy it
The FF500 is for riders who want a fast, light e-mtb with a big battery. It is not for utility or comfort. You should buy it if you value speed and range over convenience.
- You want a 45 km/h top speed for fast commutes.
- You need a 960 Wh battery for long rides.
- You prefer a lighter bike at 18.1 kg.
Look elsewhere if you need a step-through frame or a throttle. Also consider other bikes if you want a longer warranty. The warranty is not published, so you cannot compare it.
