Understanding battery capacity and range
What battery capacity really means for your ride
When you’re looking to ride your electric scooter or electric bike for up to 80 km (about 50 miles), understanding battery capacity is crucial. The battery is the heart of your electric ride, directly affecting how far you can go on a single charge. Battery capacity is usually measured in watt-hours (Wh), which tells you how much energy the battery can store. The higher the Wh, the longer your range miles—assuming all other factors stay the same.
How battery specs translate to real-world range
It’s easy to get lost in numbers, but here’s the simple part: a bigger battery pack generally means more miles range. However, the actual distance you’ll cover depends on more than just the battery size. The motor power, your average speed mph, tire type (like fat tire or standard), and even how much you use pedal assist or throttle all play a role. For example, a 500Wh battery on a lightweight ebike with pedal assist will likely take you farther than the same battery on a heavier, pure electric scooter with a powerful hub motor.
- Motor and battery: The combination of your motor and battery ebike setup determines how efficiently you use stored energy.
- Speed and riding style: Riding at higher speed mph or using throttle miles instead of pedal assist drains the battery faster.
- Tire and terrain: Fat tire electric bikes or scooters with disc brakes and rear hub motors may use more energy, especially on rough terrain.
Why battery type and build matter
Most modern electric scooters and electric bicycles use lithium battery technology. Lithium batteries are lighter, last longer, and provide more consistent power compared to older types. The way your battery is built—its quality, how it’s integrated into the frame, and even how easy it is to remove or replace—can impact both your battery life and your overall riding experience.

How to calculate the right battery for your needs
Calculating the Battery Size for Your Desired Range
When planning for an 80 km ride on your electric scooter or ebike, you need to match your battery capacity to your expected range miles. The process is straightforward, but it’s important to factor in real-world conditions like speed, tire type, and motor efficiency. Here’s how you can estimate the right battery pack for your needs:
- Determine your average energy consumption: Most electric scooters and electric bikes consume between 10 and 20 watt-hours (Wh) per mile, depending on the motor, riding style, and terrain. For fat tire or heavy builds, expect higher consumption.
- Convert your desired range to miles: 80 km is roughly 50 miles. This helps when comparing battery specs, as many manufacturers in the United States list range miles.
- Calculate total energy needed: Multiply your estimated consumption (Wh per mile) by your target miles range. For example, if your scooter uses 15 Wh per mile, you’ll need about 750 Wh for 50 miles (15 Wh x 50 miles).
- Check battery voltage and amp-hours: Battery capacity is often listed as voltage (V) times amp-hours (Ah). For example, a 48V 16Ah battery gives you 768 Wh (48 x 16).
It’s easy to overlook factors like pedal assist, throttle miles, or pure electric mode. Using pedal assist can extend your battery life, while riding at higher speed mph or using only the throttle will drain your battery faster. Also, tire electric types (like fat tire or standard) and motor type (hub motor, rear hub, or front rear setups) can affect efficiency.
| Battery (V x Ah) | Total Wh | Estimated Range (miles) |
|---|---|---|
| 36V 20Ah | 720 | 45-50 |
| 48V 16Ah | 768 | 50-55 |
| 52V 20Ah | 1040 | 65-70 |
Remember, your actual range will depend on factors like speed, tire pressure, weight, and how much you use pedal assist versus throttle. If you’re planning to build or upgrade your own electric bike or scooter, always check compatibility with your motor and controller. A lithium battery is recommended for its balance of weight, battery life, and performance.
For those who want to maximize their ride time and ensure a reliable commute, investing in a quality bike battery or battery ebike pack is key. Don’t forget to consider disc brakes and tire quality for safety, especially if you’re upgrading to a larger battery for longer rides.
