Previously, on the Delfast blog, we shared articles about how to mount a camera on an electric bike. This time, we’re diving into something more critical: the range of electric bikes and how to calculate it. So, how far can you go on a single charge?

What is the Range of Electric Bikes?

The maximum range of some high-performance e-bikes can reach up to 200-250 miles. These are typically designed for long-distance travel and come with powerful 3 kW batteries. Standard models with smaller batteries (around 400-500W) usually offer 60-75 miles before needing a recharge. For city commuting, most e-bikes can cover 30-40 miles on a full charge.

In 2017, Delfast made history by officially revolutionizing the e-bike market when the Delfast Prime traveled an impressive 367 km (228 miles) on a single charge.

Factors That Affect the Range of an Electric Bike

Calculating the exact range of an electric bike isn’t straightforward—many factors influence it:

• Weather conditions: On sunny days, the range can be about 15% longer than on rainy days.
• Tire pressure: Soft tires are good for city riding but not ideal for hilly or mixed terrain.
• Rider weight and luggage: Extra load increases energy consumption.
• Battery type: Lower-power batteries may lose efficiency with frequent stops and starts.
• Motor and battery weight: Heavier components can reduce overall range.
• Riding style: Faster speeds and harder pedaling drain the battery quicker.
• Terrain: Flat roads give better range than mountainous ones.

What About Range on Lithium-Ion Batteries?

Lithium-ion batteries are the most common in e-bikes due to their efficiency and durability. They come with built-in control systems that help manage power usage effectively.

To maximize the life of a lithium-ion battery, follow these tips:

• Charge a new battery fully before use. Partially charged batteries at purchase can lead to reduced capacity over time.
• Recharge immediately after discharge. Letting the battery fully drain can shorten its lifespan.
• Avoid exposing the battery to extreme heat. Ideal storage temperature is between 68–77°F (20–25°C).
• Store the battery in a cool, semi-discharged state for long-term storage.
• Do not charge a cold battery. Allow it to warm up to room temperature first.
• Always use the original charger to avoid damage.

Why Delfast E-Bikes Offer the Longest Ranges

Delfast bikes are engineered for long-distance rides. Models like the Delfast Offroad, Delfast Prime 2.0, and Delfast Top 3.0 were developed with extended range in mind, offering some of the best performance in the industry.

How to Calculate the Range of Your E-Bike

The range depends on two main factors: battery capacity and riding speed. The higher the battery capacity, the longer the range. However, higher speeds tend to reduce it.

Electric bike batteries are measured in volts (V) and ampere-hours (Ah). To find the watt-hour (Wh) capacity, multiply V by Ah:

Example: - A 50V 15Ah battery = 750 Wh - A 30V 20Ah battery = 600 Wh

On average, it takes 4–35 Wh to travel one mile. For flat terrain, using 4 Wh per mile gives a much longer range:

750 / 4 = 187.5 miles 600 / 4 = 150 miles

For mountainous areas, where energy consumption is higher, using 30 Wh per mile results in:

750 / 30 = 25 miles 600 / 30 = 20 miles

Delfast Smart Technology

Delfast e-bikes are more than just powerful—they're smart. Our bikes come with built-in apps like anti-theft systems, remote start, Bluetooth connectivity, and motor blocking features. Whether you're looking for convenience or security, Delfast has you covered.
