What people ask about the Fiido D3 Pro

How much does it weigh?

The Fiido D3 Pro weighs 17.7 kg. That is 33% lighter than the median folding bike. You can carry it up stairs, but it is not featherweight.

How much torque does it have?

It has 60 Nm of torque. That is 50% above the median for its type. This helps on hills, even with a modest motor.

What speed class is it?

It is a standard pedelec class. That means it assists up to 26 km/h. You pedal to get power, as there is no throttle.

How far does it really go?

The manufacturer claims 80 km. MathBikes estimates 28 km, with a band of 24 to 31 km. That estimate is 65% 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 price is 399 USD, which is low. Running costs depend on electricity and maintenance. The warranty is not listed, so factor that into your budget. Use the cost calculator for a fuller picture.

Where it falls short

The biggest drawback is the battery. At 374 Wh, it is 46% below the median for its type. That directly cuts the estimated range to 28 km, which is 43% below the class median. If you ride longer than that, you will run out of power.

Who should buy it

This bike fits riders who value low cost and easy portability over long range. It is a practical choice for short commutes or errands in a compact area.

  • You need a light bike to carry onto a train or up stairs.
  • Your daily ride is under 20 km and you can charge at work or home.
  • You want an affordable entry into e-bikes without a big investment.

Look elsewhere if you need a long-range bike or plan to carry heavy loads. The max payload is 120 kg, and it is not cargo capable. Also, if you prefer a step-through frame, this bike does not have one.
