The DYU C3 does not lead on a single measured axis here. That does not make it the wrong bike, but it does mean the DYU King 750 is the one to justify not buying.
What each one costs to own
Over 5 years the DYU C3 costs about 1,000 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 C3 covers about 19,200 km before its pack is due for replacement; the DYU King 750, about 51,200 km. Ride less than that and the replacement never enters the sum.

Verdict
On the measured axes the DYU C3 is the better buy, and the DYU King 750 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.
