DYU C6 vs DYU D3F
On the numbers that decide this pair, the DYU C6 is 11.8 kg lighter than the DYU D3F. 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 | DYU C6 | DYU D3F |
|---|---|---|
| Estimated range | 32 km | 25 km |
| Battery | 450 Wh | 360 Wh |
| Weight | 29.9 kg | 41.7 kg |
| Motor torque | 45 Nm | 40 Nm |
| Top speed | 24 km/h | 24 km/h |
| Price | $1,099 | $499 |
| 5-year cost | $1,548 | $1,093 |
Where each one wins
- DYU C6 is 11.8 kg lighter.
- DYU C6 is 7 km further on range.
- DYU C6 is 90 Wh more battery.
- DYU C6 is 5 Nm more torque.
The DYU D3F does not lead on a single measured axis here. That does not make it the wrong bike, but it does mean the DYU C6 is the one to justify not buying.
Who each one is for
DYU C6
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:
- 45 Nm of torque, so long climbs will ask for your legs
DYU D3F
Suits you if you want:
- folds, so it fits a boot, a train or a hallway
- rated to 120 kg of rider and luggage together
What it asks in return:
- 40 Nm of torque, so long climbs will ask for your legs
- 41.7 kg, which is a bike you park rather than carry
- about 25 km estimated, so it wants a charge most days
- 360 Wh, a small pack to keep an eye on in winter
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 D3F costs about 421 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 C6 covers about 24,000 km before its pack is due for replacement; the DYU D3F, about 19,200 km. Ride less than that and the replacement never enters the sum.
| Over five years | DYU C6 | DYU D3F |
|---|---|---|
| Purchase price | $1,099 | $499 |
| Charging | $68 | $68 |
| Servicing | $648 | $648 |
| Battery replacement | ||
| Resale value | $-268 | $-122 |
| Total | $1,548 | $1,093 |

Which one to buy
- Pick the DYU C6 if you ride to the edge of the battery and dislike planning around it.
- Pick the DYU C6 if you would rather charge less often than carry less weight.
- Pick the DYU C6 if you carry the bike up steps, onto a train, or into a flat.
- Pick the DYU C6 if your route has real hills, or you carry cargo or a passenger.
- Pick the DYU D3F if the five-year total is what you are optimising.
Verdict
On the measured axes the DYU D3F is the better buy, and the DYU C6 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.
