Summary
Not directly, because the batteries run from 374Wh in Velotric's Tempo e-bike and 451.2Wh in NIU's KQi Air scooter to as much as 17.3 kWh in Zero's motorcycles, and each maker states its test conditions differently or not at all. Dividing the claim by the battery size gives a fairer view, and it shows pedaling doing a large share of the work in an e-bike's headline figure.
Four range claims and what stands behind them
| Vehicle | Battery | Range claim | Conditions stated |
|---|---|---|---|
| Velotric Tempo (e-bike) | 374Wh | 60 miles on pedal assist, 40 on throttle | "A 187-lb rider using Eco mode on flat roads" |
| Brompton Electric T Line (folding e-bike) | 345Wh | Up to 56 miles | Varies with "assist level, terrain, and rider weight" |
| NIU KQi Air (e-scooter) | 451.2Wh | 31 miles, or 30 in another section of the page | None |
| Zero Motorcycles (range of models) | 3.6 to 17.3 kWh | An example of "Max Range: 223 Miles" | "Max numbers achieved in strict testing protocol" |
Miles per 100Wh
Worked out from the makers' own figures, the Tempo's pedal-assist claim comes to 16.0 miles per 100Wh and its throttle-only claim to 10.7. The Brompton's 56 miles from 345Wh is 16.2 miles per 100Wh. The KQi Air, which has no pedals, comes to 6.9.
The only difference between the Tempo's two numbers is whether the rider pedals. Same bike, same battery, same stated test rider, and the claim drops by a third on the throttle alone. The scooter, carrying a standing rider on 9.5-inch wheels, is lower again.
Zero's figure cannot be converted the same way. The charging page shows the 223-mile example without saying which battery produced it.
What each maker says changes the number
Lectric lists eleven things that change an e-bike's real-world range, among them pedal assist level, throttle use, rider and cargo weight, hills, wind and temperature. It adds that range estimates "are not promises that every ride will produce an identical number."
Zero's list for its motorcycles is shorter and overlaps almost completely: "Steep climbs, driving into wind, weight, and tire inflation will all impact range," and actual range varies with "speed, weight, wind, incline etc." Zero also says its range numbers "don't always reflect average typical use."
Charging time scales with the battery
NIU gives the KQi Air a 5-hour charge. Zero says its motorcycles take about 8 hours on a household Level 1 outlet, "Up to 10 hours for larger batteries," or 1 to 4 hours on a Level 2 charger, and that "Level 3 is not yet available for Zero Motorcycles."
