5 Things That Affects An E-Scooter's Range

Why the range of escooters varies: Not all riding conditions are ideal

The purpose of an electric scooter (or escooter) is to get you from place to place. It follows that how far the scooter can go is one of the most important considerations. However, riders often complain that the range advertised is less than the range they get in real world conditions. Why is that so though? In this article we take an in-depth examination into all the factors that affects or compromises an escooter's max range per charge.

The max range of electric scooters is affected more by external factors, including terrain, weight, slope, temperature, and even whether the air tires have been pumped to the manufacturer's specifications. 

The short answer is that the stated range of an escooter is usually the range achievable under IDEAL conditions. This is not a ploy to over-market or short-change the e-scooter buyer. The manufacturer has to to set certain controls for testing a scooter's range and will accordingly publish that data in its advertising material. 

Of course, some manufacturers outright state under what conditions its data based on, but some do not. A responsible manufacturer (which is really what you want when you splash out a hefty sum for a last mile solution) will clearly state the conditions and circumstances under which they achieve the range they specify. A good example is the recently released Inmotion V10 electric unicycle (EUC). The published range of the V10 is “~70km”. The manufacturer is even careful enough to use the “~” symbol to indicate that this is an approximation. This range was said to be achievable under these conditions:

  • while riding under full power;
  • with 75kg load
  • at temperature of 25°C
  • riding at an average speed of 15km/h
  • on a smooth pavement

They have even gone as far as to declare in advance that “riding habits, environment, temperature, road conditions, load and other factors will affect the range”. This careful and clear treatment of range may have something to do with the intense competition between electric unicycle manufacturers at the time the article was written. Electric unicycle manufacturers are launching large numbers of new high-end machines  and are competing for the purchasing power of riders who care very much about performance.

Many electric scooter manufacturers spare the consumer such details, and simply publish a single figure for the range. While this may be simple and easy for the end consumer to understand, it can lead to customer dissatisfaction when customers take the range at face value.

In this article, we will show you how the battery's maximum range is calculated, and more importantly, what factors affect your electric scooter's your battery so that you can avoid them and maximize your range.


The battery capacity of your scooter is analogous to the size of the fuel tank in a car. The more fuel you can carry, the longer the drive you can get. The motor will be like the engine of a car: the larger it is, the more powerful it is, the power-hungry it will be.

With some basic arithmetic and intermediate physics, we can calculate the theoretical range based on the specifications of the battery and motor. For the tech geek, feel free to geek away:

Above: You can calculate the range if we know the scooter's specifications like battery capacity and motor power. 

Let’s say we want to calculate the range of a typical medium-sized electric scooter with these specifications:

  • Battery: 36 Volts (V) 10.5 Amphere-hour (Ah)
  • Motor power*: 250 Watts (W)

The first formula one that everyone knows (hopefully):

DISTANCE (Km) = SPEED (Km/hr) x TIME (hr)

This formula states that if we know the speed we ride at (assuming we ride at a constant speed), and the duration the scooter can sustain the speed until its battery runs out, we can calculate the distance it can travel per full charge of its battery.

For SPEED, we will use the highest possible speed at which we can ride the escooter. The speed limit for Personal Mobility Devices (PMD) in Singapore, where this article is written, is 25km/hr. And the average at which people use an e-scooter on roads/pathways is close to that number as well. So we'll use this figure for speed.

For TIME, we can calculate it from the battery capacity and motor power.

To do this, we need to figure out the battery capacity. This is measured in Watt-hours (Wh), that is, the energy (in Watts) it can deliver in one hour.

Watt-hour (Wh) = Ampere-Hour (Ah) x Voltage (V)

So the capacity of our battery is 10.5Ah x 36V = 378Wh

Knowing the amount of energy in the battery, and knowing the power (and hence energy consumption) of the motor, we can now calculate how long it will take for the escooter's motor to burn through its stored energy:

TIME (hr) = Battery capacity / Power consumption = 378Wh / 250W = 1.512 hr

Now we have the SPEED and TIME to put into our first formula:

DISTANCE = SPEED x TIME = 25 Km/hr x 1.512hr = 37.8 km.

So in theory, this scooter will be able give you for 37.8 km per full charge before its battery is fully depleted.

* Note: some manufacturers indicate peak power instead of nominal (average) power. If both figures are indicated, use nominal power for a conservative estimate.

Above: understanding your escooter’s range and knowing what affects it reduces the chances of you running out of battery and getting stranded.

In real life situations though, those are not all the factors you need to consider. The calculation has so far has only factored in the battery and motor. We have not yet taken into consideration the rider, riding conditions and other factors.

Now we will examine in detail the other factors that can negatively impact your electric scooter's range, and what you can do to squeeze out the maximum mileage from your e-scooter.

Other Factors that Affect E-Scooter Range

Broadly speaking, these are the other considerations when calculating max range:

  • Overloading
  • Insufficient tyre-pressure
  • Riding uphill
  • Riding aggressively
  • Riding or storing escooter in high temperatures

Let’s look into each one in detail.


Above: lightweight escooters like the Inokim Mini work best with lightweight riders.

An electric scooter will have to work harder to move a heavier rider compared to a lighter one as more power is needed to move a heavier load.

All electric scooters have an indication for the maximum safe payload. Most are rated at 100 Kg, with some larger models at 120 Kg. Some high end or heavy duty models carry as much as 150 kg. The maximum load is not the same as the optimum load. It’s a common practice for electric scooters makers in the market today to use a rider weight load of about 75 Kg for performance tests. This is understandable because 75 kg is the average weight of a healthy adult male.

In other words, any rider heavier than 75 Kg can usually expect the range achievable to be lower than the published figure.

Problems with overloading tend to happen when large riders buy lightweight scooters for the sake of portability.

Of course, some riders using electric scooters for first-mile and last-mile commute need to bring their escooters onto trains or buses. This is a good reason to choose lightweight electric scooters like the Inokim Mini or the Zero 2.0.

These scooters may be underpowered for the big riders, but it is alright if the rider understands there is a trade-off and is willing to give up some range for portability.

Above: choosing an electric scooter with a motor power that matches your weight and body size is a practical starting point to make sure you get the best range.


When purchasing a scooter, where possible, select an escooter with a motor power that matches your body size and weight. This is especially important if you are a large person.

Where practicable, heavy riders should choose motor powers of 350W to 500W or more like the Inokim Quick 3, Zero 10X or other powerful models so the scooter is not constantly performing under strain.

During purchase, the electric scooter salesperson can give you some insights on range versus scooter motor power. Filter the salesperson’s opinions to control for sales-commission motivations and you will have a sense of which scooter power is suitable for you. If there are hills on your route, it usually pays to favour a higher powered scooter (see “Riding uphill” later in this article).

For the scooter itself, shed weight by removing unnecessary accessories and attachments like bags, bottle holders and such to lighten the load on the scooter. Some countries may even have regulations that limit the weight of an electric personal mobility device.

Insufficient Tyre Pressure

It is well-known in both the cycling and automobile community that under-inflated tyres result in reduced fuel economy. Without going into complicated physics or mathematics, the simple but factual explanation is that under-pressurized wheels deforms the wheel from its optimal shape. This results in, among other things, increased contact surface between the wheel and the ground. Generally, more contact area means more friction.

There have been no scientific studies done specifically for electric scooter tyre pressure performance. But research for automobiles shows a clear correlation between rolling resistance and tyre pressure. The closer the tyre pressure is to the pressure intended by the manufacturer, the lower the rolling resistance. A reduction of rolling efficiency happens when the tyres are even marginally lower than the optimum prescribed pressure.

It is important to emphasize that avoiding insufficient pressure is not the same as encouraging over-pressurizing the tyres, which has its own set of problems. The important thing to do is to maintain the correct pressure as indicated by the scooter/tyre manufacturer. This pressure is usually indicated in the user’s manual. The pressure indicated on the tyre itself is usually the maximum pressure, not optimum pressure.


Above: Bicycle pump with pressure gauge. Extremely useful and importatnt to maintain optimal tyre pressure.

If you don’t yet own one, get your hands on a tyre pump with a pressure gauge. This is indispensable. You can check the tyre pressure and pump up the tyre with a single device. Make it a point to check the tyre pressure every few weeks and inflate if it falls below the optimum pressure. Maintaining sufficient pressure has the bonus effect of reducing the chances of getting a flat tire, and increasing the tyre’s useful lifespan. Every scooter has a different optimum tyre pressure, so be sure to check yours with the shop you bought from.

Above: The Segway ES2 is indicated to be able to go ‘up to’ 15 miles (24 Km) depending on ‘riding style and terrain’.

Gradient has a massive impact on electric scooter range. If you ride a bicycle, you will know from experience that riding uphill, even when the slope is quite gentle, takes much more effort than riding on level ground.

Without going into complicated calculations, it is enough to say that any uphill climbs on your route will shave a significant chunk off the range indicated on your scooter manual. Given that scooter-range is calculated on perfectly flat ground but your actual route is not, you are unlikely to ever match the scooter’s published range.

To put things in context, many riders buy an electric scooter to spare them the effort of climbing difficult slopes on foot or on a bicycle. So the loss of range because of a slope is probably a fair trade-off for the effort saved.


If possible and necessary, choose a longer route that goes around the slope. Unless the detour is unnecessarily long, you will usually still end up positive on the range.

Riding Aggressively

Physics tells us that an object at rest tends to stay at rest and an object in motion tends to stay in motion. It takes energy to get a stationary object to move, to increase its speed or to slow it down.

The general energy consumption associated with the type of scooter activity, (from lowest to highest) is listed here:

  1. Scooter is running at a constant speed
  2. Scooter is braking*
  3. Scooter is accelerating from lower speed to higher speed
  4. Scooter is accelerating from stationary position
    *only applies to scooters with electronic brakes

For electric scooters that use an electronic brake (as opposed to a bicycle-style physical brake), battery power is also consumed when braking because the scooter brakes by the using the motor to resist motion.

In short, the more often and intensely you accelerate or decelerate during your ride, the shorter your range will be.

Above: with a patient riding style, even a tiny seated escooter like the DYU Supreme can achieve an impressive range of 60 Km, a range more commonly found on much larger machines.


When it comes to range, patience is a virtue. Reach your cruising speed by accelerating gently without haste. Maintain as constant a speed for as long as possible. The optimum speed is usually the highest speed which can be sustained by the motor without it sounding like it is struggling. There’s a reason why this is called a “cruising” speed. It should be a comfortable speed and certainly not the maximum speed.

If you are riding an escooter with electronic brakes, where possible, coast to a stop rather than braking hard. By riding this way, not only will you gain more kilometres, it will be a safer ride as well. As a bonus Your tyre and brake pads will also have a longer lifespan.

Riding or Storing Scooter in Hot Temperatures

We can’t control the temperature we ride in. But it is useful to know what temperatures are best for your scooter. The main concern here is the health of the battery, which is directly related to range.

The optimum operating temperature of batteries is similar to what is comfortable for people. Battery manufacturers usually point to 20 ℃ or slightly lower as the optimum operating temperature, and with 20 ℃ to 30 ℃ as an acceptable operating range.

avoid leaving your electric scooter in the car boot in hot summer days

Above: It is tempting to keep your escooter in the car boot for convenience. But this can expose the battery to unhealthy high temperatures on warm days.

This temperature offers the best battery capacity (which means it can be charged and discharged more completely and easily) and is best for the lifespan of the battery in terms of total charge cycles (cycle life). At temperatures higher or lower than this range, both capacity and lifespan start to suffer penalties. As the battery capacity drops, so too does your range.


As far as temperature is concerned, think of your escooter as a living creature, sensitive to warmth and cold just like you. Avoid storing your escooter in the boot of the car under the hot summer sun, or leave it parked for long periods in direct sunlight. For storage, a cool dry place that is indoors and out of the elements and protected from winter temperature will protect the scooter. It is comfortable when you are comfortable.


Unless you are the kind of rider who rides a scooter to death and buys a new one every year, being mindful of the factors that hurt the range of your escooter will help you can get the best mileage and a longer lifespan from your ride. And because the battery is often the most expensive component in your scooter and may cost up to a third of the scooter's price, it will ultimately help you save money as well.

It is also important to understand that electric scooter batteries have a limited number of charge cycles (battery cycle life). This is generally about 500-600 accumulated charge cycles, depending on the quality and brand of the battery cells. Their capacity to hold charge in lithium ion batteries degrades gradually over time - the same as your iPhone or Samsung smart phone. So for regular riders, it may be hard to avoid a battery replacement after a long period of intense use. When the time comes, however, pat your scooter for having served its purpose well and accept the need to revitalise it with a brand new battery or retire it forever.
