VIVI MT20UL vs VIVI MT26GUL

Where each one wins

• VIVI MT26GUL is 125 Wh more battery.
• VIVI MT26GUL is 9 km further on range.

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 MT26GUL is the one to justify not buying.

What each one costs to own

Over 5 years the two land within 5% of each other, which is inside the error on any of these inputs. Cost is not the deciding factor here.

That figure moves mostly on the battery. The VIVI MT20UL covers about 19,947 km before its pack is due for replacement; the VIVI MT26GUL, about 26,613 km. Ride less than that and the replacement never enters the sum.

Which one to buy

• Pick the VIVI MT26GUL if you would rather charge less often than carry less weight.

Verdict

On the measured axes the VIVI MT26GUL is the better buy, and the VIVI MT20UL 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.
