What each one costs to own

Over 5 years the VTUVIA SX20 costs about 700 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 VTUVIA CMB Pro covers about 35,840 km before its pack is due for replacement; the VTUVIA SX20, about 38,400 km. Ride less than that and the replacement never enters the sum.

Verdict

On the measured axes the VTUVIA SX20 is the better buy, and the VTUVIA CMB Pro 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.
