Fiido M21 vs Fiido T1 Pro
On the numbers that decide this pair, the Fiido M21 is 11.4 kg lighter than the Fiido T1 Pro. Everything else is below, including where it loses.
Range is our estimate under the reference ride, not the manufacturer's claim. Cost is over 5 years at 3,000 km a year, on the same formula the cost-of-ownership calculator runs. How we work this out
| Spec | Fiido M21 | Fiido T1 Pro |
|---|---|---|
| Estimated range | 37 km | 45 km |
| Battery | 557 Wh | 696 Wh |

Where each one wins
- Fiido M21 is 11.4 kg lighter.
- Fiido T1 Pro is 139 Wh more battery.
- Fiido T1 Pro is 8 km further on range.
- Fiido T1 Pro is 5 km/h faster.
The Fiido M21 leads on 1 of these, the Fiido T1 Pro on 3. 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 two land within 5% of each other, which is inside the error on any of these inputs. Cost is not the deciding factor here.
That figure moves mostly on the battery. The Fiido M21 covers about 29,707 km before its pack is due for replacement; the Fiido T1 Pro, about 37,120 km. Ride less than that and the replacement never enters the sum.

Which one to buy
- Pick the Fiido T1 Pro if you ride to the edge of the battery and dislike planning around it.
- Pick the Fiido T1 Pro if you would rather charge less often than carry less weight.
- Pick the Fiido M21 if you carry the bike up steps, onto a train, or into a flat.
- Pick the Fiido T1 Pro if your commute has fast stretches where the assist cutting out matters.
Verdict
On the measured axes the Fiido T1 Pro is the better buy, and the Fiido M21 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.
