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 |
| Weight | 24.9 kg | 36.3 kg |
| Motor torque | 60 Nm | 60 Nm |
| Top speed | 40 km/h | 45 km/h |

- 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.
Who each one is for
Fiido M21
Suits you if you want:
- 60 Nm of torque, enough for rolling ground
- built to carry a load rather than just a rider
- rated to 120 kg of rider and luggage together
- about 37 km estimated, which covers a 18 km each-way commute
Fiido T1 Pro
Suits you if you want:
- 60 Nm of torque, enough for rolling ground
- fast class, which keeps up with city traffic
- built to carry a load rather than just a rider
- rated to 200 kg of rider and luggage together
- about 45 km estimated, which covers a 22 km each-way commute
What it asks in return:
- 36.3 kg, which is a bike you park rather than carry
- fast class, so it is registered and helmeted in most places
Each line above is read straight from the specification: torque, weight, payload, battery and our range estimate. Nothing here is a preference, and neither bike is being recommended over the other.
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.
| Over five years | Fiido M21 | Fiido T1 Pro |
|---|---|---|
| Purchase price | $999 | $999 |
| Charging | $68 | $68 |
| Servicing | $972 | $972 |
| Battery replacement | ||
| Resale value | $-244 | $-244 |
| Total | $1,795 | $1,795 |
Run these numbers on your own mileage
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.
