DYU C1 vs DYU FF500

Where each one wins

• DYU FF500 is 51 Nm more torque.
• DYU FF500 is 21.8 kg lighter.
• DYU FF500 is 510 Wh more battery.
• DYU FF500 is 25 km further on range.
• DYU FF500 is 13 km/h faster.

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.

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.

Which one to buy

• Pick the DYU FF500 if you ride to the edge of the battery and dislike planning around it.
• Pick the DYU FF500 if you would rather charge less often than carry less weight.

• Pick the DYU C1 if the five-year total is what you are optimising.

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.
