How Far Can An Electric Bike Go On One Charge?
One of the highest priorities of an ebike owner is knowing how far they can ride before recharging their battery. Range anxiety is a real thing and can turn a fantastic day into a stressful one. So, how far can an electric bike go on one charge?
How To Calculate Electric Bike Range
First, you need to know the battery's capacity. This is indicated in watt-hours (Wh). Then, you need to estimate the power consumption, which depends on the variable factors we discuss later in this article. But, on average terrain, most electric bike motors consume 10 to 20 watt-hours per mile (Wh/mile) and moderate assistance.
So, to calculate the theoretical range of an ebike, you need the following formula:
Formula
Range (miles)=Battery Capacity (Wh)/Power Consumption (Wh/mile)
Example Calculation
Battery Capacity: Suppose your e-bike has a 500Wh battery.
Power Consumption: Assume an average power consumption of 15Wh/mile.
Range=500Wh/15Wh/mile =33.33miles
What Affects Electric Bike Range?
Having a simple formula to work out your ebike's range is great. However, the answer is more complex. There are many variables that affect an electric bike's range. It's important to know these variables so you don't have to push up that last hill on the way home.
Rider's Weight
Your weight is a significant factor in how far your electric bike will take you. Heavier riders require the motor to work harder, which drains the battery faster. Lighter electric bike riders will find that they can ride further on one charge.
Cargo Weight
Sometimes, we have to carry extra stuff with us on our rides. Whether you're a delivery person or carrying stuff for a nice day out, your range will drop when you're loaded up. So, if you know you'll be carrying extra weight, remember that you may have to manage your battery life a little more carefully.
Battery And Motor Combo
Your electric bike's battery and motor combo make a huge difference in its range. An ebike with an efficient motor powered by a large-capacity battery will give you excellent range. For example, a 500Wh battery would give you more range than a 300Wh battery. Therefore, it's essential to know your typical journey length and cross-reference it with the range of an electric bike before buying.
The Profile Of Your Journey
When we say "profile of your journey", we mean how hilly it is. If your local area has flat, smooth roads, you'll achieve a good range from your ebike. However, your motor and battery must work harder if you ride in a hilly area, as climbing hills zaps power. With this in mind, plan your route to avoid steep hills if range is an issue.
Weather Conditions
There's nothing we can do about the weather, and unfortunately, it makes a difference to your bike's range. Cold weather can reduce battery efficiency, cutting your range. But you'll notice that riding in milder temperatures will give you optimal battery performance. Additionally, wind plays a part in your range. Riding into a headwind for long periods has the same effect as riding up a gradual hill, which will use battery power up quicker than you may expect.
You can fight the effects of cold weather by insulating your battery. This will keep the battery closer to its optimal temperature, improving range.
Your Riding Style
In the early days of ebike ownership, you'll love accelerating hard and using high assistance levels. However, you'll soon learn that riding aggressively with spirit prematurely uses up your battery power.
To extend your range, you must learn how to ride more smoothly. Avoid stopping and starting by being aware of your surroundings. Slow down for traffic lights and junctions well in advance to take advantage of rolling starts; this is more efficient than setting off from a standstill every time. Also, try to maintain a steady, moderate pace rather than riding at high speeds.
Riding in high assistance levels demands more power from the battery, reducing range. If you need to ride further, use lower assistance levels. You'll need to work harder, but your range will be extended.
Tyre Pressure
One aspect of riding an electric bike often overlooked is tyre pressure. Underinflated tyres have more rolling resistance, which drains your battery faster. We recommend checking your tyre pressures regularly to ensure your battery lasts as long as possible. But don't over-inflate your tyres, as you will experience less grip on the road.
Terrain Type
The terrain you ride on affects how long your battery lasts. Riding on rough surfaces uses more battery power than smooth roads. So, if you notice your battery running low when riding off-road, try to find a smoother route to help you get home.
Battery Age
Your electric bike battery degrades as it ages. Depending on the model, most batteries are good for 800 to 1500 charge cycles. One charge cycle is when the battery depletes to any level and is recharged. As a battery approaches the end of its charge cycles, it holds less charge and depletes more quickly. Regularly checking your battery's health and replacing it when necessary can keep you going further.
Maintenance
The final factor that affects range is how well you care for your electric bike. If you regularly clean and lubricate your chain and inspect the brakes and other components, your ebike will run more efficiently, allowing you to ride further on a charge.
Real World Example
Let's look at some real-world examples. The 417.6Wh battery on a 250W Fiido X on a flat city commute might get you 130 KM / 80.7 Miles. Alternatively, the Fiido Air's 208.8Wh battery and 250W motor should last 80km /50 miles. But, on hilly terrain with a heavy load, expect fewer miles.
How Far Can an Electric Bike Go on One Charge? - Answered!
As you can see, the answer to the question of "How far can an electric bike go on one charge?" isn't straightforward. Several factors determine how far you can ride before needing to plug in. But don't get too stressed over this, as electric bike brands state the ranges of each product. It's important to understand that these stated figures are probably estimates or the results of testing in optimum conditions. This is understandable, as electric bike brands can't predict everyone's experiences.
Fiido offers some excellent electric bikes with long ranges, thanks to efficient motor and battery combos and drivetrains. The Fiido website is a fantastic place to start when looking for your next electric bike; check it out.
