The SAMEBIKE CY20 leads on 1 of these, the SAMEBIKE M20 on 3. Neither sweeps it, so the choice comes down to which of those you actually use.
What each one costs to own
Over 5 years the SAMEBIKE CY20 costs about 1,156 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 SAMEBIKE CY20 covers about 19,200 km before its pack is due for replacement; the SAMEBIKE M20, about 51,200 km. Ride less than that and the replacement never enters the sum.

Which one to buy
- Pick the SAMEBIKE M20 if you ride to the edge of the battery and dislike planning around it.

Verdict
On the measured axes the SAMEBIKE CY20 is the better buy, and the SAMEBIKE M20 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.
