How the VIVI " with Removable ，7 Speed performs, on paper

Computed from this bike's catalogue figures with the published formulas. Nothing here was measured on a ride.

Estimated against claimed rangeHow far the brand says it goes, against how far our formula says it does.

ClaimedNot stated

The brand states no range claim, so there is nothing to compare the estimate with. How we work this out

Estimated range by rider weight and terrainHow the estimate moves with the weight of the rider and the terrain.

The range calculator's formula with the reference ride's settings: Tour assist, mild weather, brisk pace, knobby tyres. The ring marks the published estimate (176 lb rider, rolling terrain).
