Head to head

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

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.

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.

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.
