What the numbers say
There are 17 of these in the database. The middle one costs about 989 EUR, which is below the 1,203 EUR the catalogue sits at, and carries 749 Wh of battery against a catalogue median of 720 Wh.
Weight runs to a median of 36.3 kg, above the 29.5 kg typical elsewhere, and that is most of why the estimated range lands at 51 km against 47 km across the catalogue: a heavier bike spends more of its battery moving itself. The estimate is above the catalogue median.
Across the group our estimate lands 32% under the claimed range, below the 46% we see catalogue-wide. The Koolux X7 PRO holds up best, -5% under its claim; the Koolux X9 Mini is furthest out at 64%. A wide gap is a difference of test conditions, not an accusation: a claim measured on flat ground in Eco with a light rider is a real number answering a different question.
