Understanding range — and what really affects it

Materials

"How far does it go on one charge?" is the first question almost every end-user asks, and the one a distributor is most often pushed to answer with a single number. But a wheelchair's range is not a fixed quantity the way its weight is — it's a figure measured under set conditions that real-world use almost always shortens. For a buyer, the value isn't in quoting the biggest number; it's in understanding what the number means, what moves it, and how to frame it so the chair performs to expectation in the field. Get that right and you head off the single most common after-sales complaint in the category: "it doesn't go as far as the brochure said."

What "range" actually means

Range is the distance a power wheelchair can travel on one full charge — measured under controlled, favourable test conditions. Manufacturers across the industry quote range the same way: a set rider weight, flat smooth ground, a steady moderate speed, a fresh fully-charged battery and mild temperature. Those are ideal conditions, chosen so the figure is repeatable and comparable — not so it predicts what any given user gets on a given day.

That's why you'll see range written as "up to X km." The phrase is deliberate: it states a ceiling, the most the chair will do when everything lines up, not a floor or an average. Read it the way you'd read a car's quoted fuel economy — a benchmark for comparing models, achieved in the lab, rarely matched on a real route.

The honest one-line framing for your sales team: "up to X km per charge under ideal conditions — expect less with a heavier rider, hills or cold weather." Setting that expectation before the sale prevents the complaint after it.

What really affects range

Battery size sets the size of the energy tank; everything below decides how fast that tank empties. The main factors:

Factor How it affects range Direction
Battery capacity (Wh) More stored energy means more potential distance, all else equal — watt-hours are the size of the tank Bigger Wh → further
Rider weight & load A heavier rider, plus bags, oxygen or shopping, draws more energy per kilometre Heavier → shorter
Terrain & gradient Hills, ramps, kerbs, soft ground, gravel and thick carpet all demand far more energy than flat smooth pavement Hillier / rougher → shorter
Temperature Lithium cells deliver less usable energy when cold; winter range is typically noticeably lower Colder → shorter
Tyre pressure Under-inflated tyres increase rolling resistance, so the motors work harder for each metre Softer tyres → shorter
Speed & driving style Higher speeds and hard acceleration burn energy faster than a steady cruise Faster → shorter
Stop-start use Frequent stopping and restarting (busy indoor or urban use) costs more than continuous travel More stops → shorter

The takeaway: the lab figure assumes the best case for every one of these. A real user is almost never in the best case for all seven at once — so real-world range sits below the quoted number, often well below it in winter, on hills or with a heavier rider.

How to read a manufacturer's quoted range

Once you know how the number is produced, you can read any spec sheet — yours or a competitor's — without being misled:

  • "Up to" is a ceiling, not a guarantee. Treat it as the model's best-case comparison figure, never as a promise to an end-user.
  • Compare like with like. A meaningful range comparison between two chairs assumes the same test basis. Where two figures look close, the real differentiator is usually battery watt-hours and whether a spare or second pack is available — not the headline kilometres.
  • Range and battery size are linked but not the same. Two chairs can quote similar range on very different batteries if their weight, motors and efficiency differ — which is why Wh, not range alone, is the apples-to-apples energy figure (covered in our dedicated battery guide).
  • A bigger number isn't automatically a better chair. Range trades against weight and cost: a long-range chair carries a larger, heavier battery. The right figure is the one that matches the user's real daily distance, not the largest on the page.

Setting expectations with your buyers

Wanderoll publishes range the same industry-standard way — as a rated, ideal-condition figure. For example, City Range (CITY-01) is rated up to 25 km per charge, and the folding scooter Scout is rated up to 20 km, both on removable batteries. Read both as ceilings under favourable conditions, and frame them to end-users that way.

The practical advice to pass down the chain:

  • Discount the headline for the real scenario. As a working rule of thumb, plan around the user travelling comfortably within the rated figure — not to its edge — once rider weight, terrain and weather are accounted for. Quote the distance the user actually needs between charges, with margin, rather than the maximum the chair can do.
  • For longer distances, specify more capacity — or a second pack. Where a user genuinely covers long daily distances, the answer is a larger battery or a dual-/two-battery configuration, not optimistic reading of a single number. Across the Wanderoll line, City One (CITY-02) offers a dual battery bay (288 / 576 Wh), City Flex (CITY-04) comes in two battery configurations (250 / 499 Wh), and Scout carries two removable batteries that share the load.
  • Lean on removable batteries. A quick-release pack lets the user carry a charged spare and swap mid-day — which extends real usable range far more reliably than chasing a higher quoted figure, and matters most to active or long-day users.

Should you ever quote range as a fixed promise? No. Range is a conditional estimate, not a guarantee. Match the chair's rated range to the user's daily distance between charges, build in margin for weight, hills and cold, and steer long-range needs toward larger or dual-battery models so the user can carry a spare. That's the difference between a sale that sticks and one that comes back.

Because every Wanderoll model is built on the same line and is OEM / ODM-ready from low minimums, you can stock one chair for everyday around-town range and a dual-battery option for longer-distance users under a single brand and one set of documentation — and brief your dealers with the same honest range script across both.
