Fiido D3 Pro vs Fiido X

Where each one wins

• Fiido D3 Pro is 28 Nm more torque.
• Fiido X is 240 Wh more battery.
• Fiido X is 17 km further on range.
• Fiido D3 Pro is 2.3 kg lighter.

The Fiido D3 Pro leads on 2 of these, the Fiido X on 2. Neither sweeps it, so the choice comes down to which of those you actually use.

What each one costs to own

Over 5 years the Fiido D3 Pro costs about 120 EUR less to own, once purchase, charging, servicing, a battery replacement where one is due, and resale are all counted.

That figure moves mostly on the battery. The Fiido D3 Pro covers about 19,947 km before its pack is due for replacement; the Fiido X, about 32,747 km. Ride less than that and the replacement never enters the sum.

Which one to buy

• Pick the Fiido X if you ride to the edge of the battery and dislike planning around it.
• Pick the Fiido X if you would rather charge less often than carry less weight.
• Pick the Fiido D3 Pro if you carry the bike up steps, onto a train, or into a flat.
• Pick the Fiido D3 Pro if your route has real hills, or you carry cargo or a passenger.
• Pick the Fiido D3 Pro if the five-year total is what you are optimising.

Verdict

On the measured axes the Fiido D3 Pro is the better buy, and the Fiido X needs a reason of its own: a colour, a frame, a shop you trust, a price that moves. None of those are in our numbers, and all of them are legitimate.

Range here is an estimate under one reference ride, not a measurement. Yours will differ with terrain, weight, tyres and weather, which is what the range calculator is for.
