DYU C1 vs DYU FF500
On the numbers that decide this pair, the DYU FF500 is 51 Nm more torque than the DYU C1. 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

| Battery | 450 Wh | 960 Wh |
| Weight | 39.9 kg | 18.1 kg |
| Motor torque | 35 Nm | 86 Nm |
| Top speed | 32 km/h | 45 km/h |

The DYU C1 does not lead on a single measured axis here. That does not make it the wrong bike, but it does mean the DYU FF500 is the one to justify not buying.
Who each one is for
DYU C1
Suits you if you want:
- rated to 120 kg of rider and luggage together
- about 32 km estimated, which covers a 16 km each-way commute
What it asks in return:
- 35 Nm of torque, so long climbs will ask for your legs
- 39.9 kg, which is a bike you park rather than carry
DYU FF500
Suits you if you want:
- 86 Nm of torque, which is steep-hill territory
- 18.1 kg, light enough to carry up a flight of stairs
- fast class, which keeps up with city traffic
- rated to 150 kg of rider and luggage together
- about 57 km estimated, which covers a 28 km each-way commute
What it asks in return:
- 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 DYU C1 costs about 1,140 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 DYU C1 covers about 24,000 km before its pack is due for replacement; the DYU FF500, about 51,200 km. Ride less than that and the replacement never enters the sum.
| Over five years | DYU C1 | DYU FF500 |
|---|---|---|
| Purchase price | $799 | $1,999 |
| Charging | $68 | $68 |
| Servicing | $648 | $972 |
| Battery replacement | ||
| Resale value | $-195 | $-488 |
| Total | $1,320 | $2,551 |

Which one to buy

Verdict
On the measured axes the DYU C1 is the better buy, and the DYU FF500 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.
