Electric Scooter Battery Range Calculator

Pick a starting rate from a scooter whose numbers are published, not from a category label. Each row below pairs a maker's own printed pack size with its own printed range and divides one by the other. The last column is what that pair implies; it is not a figure any maker states.

The arithmetic is one division per row: 275 ÷ 18.6 = 14.8, 486 ÷ 31 = 15.7, 551 ÷ 34.2 = 16.1, and 864 ÷ 40.0 = 21.6 watt-hours per mile. Segway's ECO row is 551 ÷ 43.5 = 12.7.

Read those as best cases under each maker's own conditions, and note that only Segway prints what its conditions are. They are a floor on what a scooter can do, not a budget for a commute. The same energy arithmetic shows up everywhere a battery does work, which the watts in a 12V battery page walks through on a stationary pack.

RiderGuide, an independent test publication, rode 12 scooters until the battery died and set the result against each maker's claim. Its published protocol is a 165.0 lb rider on a fully charged pack, the scooter in its maxed-out performance mode, over a route with many stops, rough roads and some uphill travel.

Across those 12 scooters the measured range averaged 71% of the claim. The best was 90%: the VMAX VX5 Pro GT returned 19.7 of a claimed 22 miles. The worst was 53%: the Segway Ninebot Max G30P returned 21.6 of a claimed 40.4. Two more models come from makers in the table above, the NIU KQi2 Pro at 63% (15.7 of 24.9 miles) and the Segway Ninebot E2 Pro at 74% (16.0 of 21.7). That spread is why a single derate applied to every scooter would be a guess.

For a planning rate, RiderGuide prints a rule: divide the pack's watt-hours by 30, and says a 551 Wh battery gives roughly 18 real-world miles. It puts normal commuting between 25 and 35 Wh per mile. Apollo's own Explore 2.0 spec sheet prints a standard power consumption of 1.8 kW per 100 km, the units as printed, which read as energy is 18 Wh per kilometre or 29 Wh per mile. Those two independent figures are why this calculator opens at 30 Wh per mile on the 551 Wh Segway pack: the default result, 18.4 miles, is the same answer RiderGuide's own worked example gives. If you want the underlying energy-divided-by-load reasoning in its plainest form, the battery runtime calculator and the guide to how to calculate battery runtime cover it for loads that do not move.

Any rate in the table is a stand-in for the number you do not have yet. One ride replaces it with your own: your route, your weight, your weather, your tyres.

1. Charge to full and write down the pack size. Volts times amp-hours gives watt-hours, so a 48 V 10.125 Ah pack is 486 Wh. The amp-hours calculator converts in either direction if your pack is labelled the other way round.
2. Ride a route you actually ride, in the mode you actually use, and record the distance from the scooter odometer or a phone GPS.
3. Read the battery percentage left at the end. Treat it as rough: most scooter gauges read voltage, and voltage reads high when the motor is off.
4. Divide. Energy spent is pack watt-hours times the fraction used. A 486 Wh pack down to 40% over 11 miles is 486 × 0.60 = 291.6 Wh, and 291.6 ÷ 11 = 26.5 watt-hours per mile.
5. Enter that number in the consumption field above, with the mode set to the one you rode in.

Do it again on a cold morning and you have a winter figure too. Two measured numbers beat any table, because the one thing a table cannot know is you. The same method works on a pedal-assist bike, which is why the e-bike battery range calculator starts from a lower base rate: there, the rider supplies part of the power.
