VIVI ACE01 vs VIVI MT20UL
On the numbers that decide this pair, the VIVI ACE01 is 221 Wh more battery than the VIVI MT20UL. 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

- VIVI ACE01 is 8 km/h faster.

The VIVI MT20UL does not lead on a single measured axis here. That does not make it the wrong bike, but it does mean the VIVI ACE01 is the one to justify not buying.
Who each one is for
VIVI ACE01
Suits you if you want:
- 90 Nm of torque, which is steep-hill territory
- rated to 150 kg of rider and luggage together
- about 42 km estimated, which covers a 21 km each-way commute
VIVI MT20UL
Suits you if you want:
- 65 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 36 km estimated, which covers a 18 km each-way commute
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 VIVI MT20UL costs about 308 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 VIVI ACE01 covers about 38,400 km before its pack is due for replacement; the VIVI MT20UL, about 26,624 km. Ride less than that and the replacement never enters the sum.
| Over five years | VIVI ACE01 | VIVI MT20UL |
|---|---|---|
| Purchase price | $1,000 | $561 |
| Charging | $68 | $68 |
| Servicing | $972 | $972 |
| Battery replacement | ||
| Resale value | $-244 | $-137 |
| Total | $1,796 | $1,463 |

Which one to buy
- Pick the VIVI ACE01 if you ride to the edge of the battery and dislike planning around it.

Verdict
On the measured axes the VIVI MT20UL is the better buy, and the VIVI ACE01 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.
