VTUVIA CMB Pro vs VTUVIA SX20
On the numbers that decide this pair, the VTUVIA CMB Pro is 25 Nm more torque than the VTUVIA SX20. 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
| Spec | VTUVIA CMB Pro | VTUVIA SX20 |
|---|---|---|
| Estimated range | 39 km | 51 km |
| Battery | 672 Wh | 720 Wh |
| Weight | 28.1 kg | 34 kg |
| Motor torque | 85 Nm | 60 Nm |
| Top speed | 45 km/h | 32 km/h |
| Price | $2,299 | $1,299 |
| 5-year cost | $2,779 | $2,023 |
Where each one wins
- VTUVIA CMB Pro is 25 Nm more torque.
- VTUVIA CMB Pro is 13 km/h faster.
- VTUVIA SX20 is 12 km further on range.
- VTUVIA CMB Pro is 5.9 kg lighter.
- VTUVIA SX20 is 48 Wh more battery.
The VTUVIA CMB Pro leads on 3 of these, the VTUVIA SX20 on 2. Neither sweeps it, so the choice comes down to which of those you actually use.
Who each one is for
VTUVIA CMB Pro
Suits you if you want:
- 85 Nm of torque, which is steep-hill territory
- fast class, which keeps up with city traffic
- rated to 150 kg of rider and luggage together
- about 39 km estimated, which covers a 19 km each-way commute
What it asks in return:
- fast class, so it is registered and helmeted in most places
VTUVIA SX20
Suits you if you want:
- 60 Nm of torque, enough for rolling ground
- folds, so it fits a boot, a train or a hallway
- rated to 150 kg of rider and luggage together
- about 51 km estimated, which covers a 25 km each-way commute
What it asks in return:
- 34 kg, which is a bike you park rather than carry
Each line above is read straight from the specification: torque, weight, payload, battery and our range estimate. Nothing here is a preference, and neither bike is being recommended over the other.
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.
| Over five years | VTUVIA CMB Pro | VTUVIA SX20 |
|---|---|---|
| Purchase price | $2,299 | $1,299 |
| Charging | $68 | $68 |
| Servicing | $972 | $972 |
| Battery replacement | ||
| Resale value | $-561 | $-316 |
| Total | $2,779 | $2,023 |

Which one to buy
- Pick the VTUVIA SX20 if you ride to the edge of the battery and dislike planning around it.
- Pick the VTUVIA SX20 if you would rather charge less often than carry less weight.
- Pick the VTUVIA CMB Pro if you carry the bike up steps, onto a train, or into a flat.
- Pick the VTUVIA CMB Pro if your route has real hills, or you carry cargo or a passenger.
- Pick the VTUVIA CMB Pro if your commute has fast stretches where the assist cutting out matters.
- Pick the VTUVIA SX20 if the five-year total is what you are optimising.
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.
