Electric Scooter Range Calculator
A manufacturer's range figure is a best case measured in a lab. This tool takes that published claim and adjusts it for how you ride — your weight, your speed, your hills and your weather — to give a realistic band. It is an estimate derived from the claim, never a test result.
The factor moving your number most is terrain (-10%). Change it above to see the effect.
A two-year-old scooter will fall short of this: lithium batteries lose roughly 20–30% of capacity after about 500 charge cycles.

Every estimate starts from the manufacturer's published claimed range and the same correction the rest of this site uses: real-world range lands at roughly 55–70% of the claim, because makers test with a light rider at a low steady speed on flat ground in mild weather with no wind. From that band, the calculator applies five adjustment factors, each of which is shown in the result and documented here so nothing is hidden.
The five factors
- Rider weight. Manufacturers test near a 165 lb rider. We reduce range by about 4% for every 20 lb above that, and add a smaller 2% per 20 lb below, capped so the adjustment never runs away. Weight is one of the largest single influences on range.
- Average speed. Air resistance rises with the square of speed, so range falls faster than speed climbs. From a 15 mph baseline we cut roughly 3% per mph above and add about 1.5% per mph below. Riding flat out is the quickest way to miss the claim.
- Terrain. Flat ground is the baseline. Rolling ground costs about 10%; genuinely hilly routes cost around 25%, because climbing draws far more current than cruising and regenerative braking recovers only a fraction on the way down.
- Temperature. Lithium cells deliver less when cold. Below 40°F we apply a 20% reduction, 40–55°F about 10%, 60–85°F none, and above 85°F a small 5% for heat. Cold mornings are the most common reason a scooter suddenly seems short-ranged.
- Tyre pressure. Under-inflated pneumatic tyres increase rolling resistance and quietly cost range. Keeping them at the recommended pressure is the cheapest range upgrade there is; if you do not check them, we apply a 7% penalty.
Why it is always a band, never a single number
Range depends on too many uncontrolled variables — wind, stop-start frequency, tyre choice, how hard you accelerate — to justify false precision. The output is a band between a conservative and an optimistic real-world figure for your inputs, and you should plan around the lower end. If your daily round trip does not fit comfortably inside the bottom of the band, choose a scooter with a bigger battery rather than hoping for the best.
The one factor this cannot see: age
The calculator assumes a healthy battery. Lithium packs lose roughly 20–30% of their usable capacity after about 500 full charge cycles — two to three years of regular commuting — so a used or older scooter will fall short of any estimate here. Gentle charging habits, keeping the pack between about 20% and 80% and avoiding heat, are what slow that decline. When you buy used, assume the real range is meaningfully below what a new example of the same model would show.
What this is not
This is not a measured test result and we never present it as one. We do not ride scooters to exhaustion and log the miles; we take the manufacturer's own published claim and apply a transparent, documented correction. The full method, including the 55–70% band, is on our methodology page. Treat the output as a well-reasoned estimate for planning and comparison, not a promise.
