On our Delfast blog, we’ve covered topics like how to mount a camera on an electric bike. Today, we’re diving into something even more important for riders: the range of electric bikes and how to calculate it. If you're wondering how far you can go on one charge, you're in the right place.

What is the range of an electric bike?

Electric bikes can have a wide range depending on their battery capacity and design. High-end models with powerful 3 kW batteries can reach up to 200–250 miles on a single charge. Standard e-bikes with smaller batteries (around 400–500W) typically offer 60–75 miles before needing a recharge. For city commuters, most e-bikes will last about 30–40 miles on a full charge.

In 2017, Delfast made headlines when its Delfast Prime model traveled an impressive 228 miles on a single charge, proving that long-range e-bikes are not just a dream.

Factors That Affect the Range of an Electric Bike

The actual range of an electric bike depends on several factors. Here’s what you should know:

• Weather conditions: On sunny days, the range can be up to 15% longer than on rainy days.
• Tire pressure: Soft tires are great for city riding but not ideal for off-road or mountainous trails.
• Rider weight and cargo: The more you carry, the more energy is consumed.
• Battery type and performance: Lower power batteries may lose efficiency with frequent start-stop driving.
• Motor and battery weight: Heavier components can reduce overall range.
• Riding style: Aggressive pedaling and higher speeds drain the battery faster.
• Terrain: Flat roads give better range compared to hilly or mountainous areas.

Understanding Lithium-Ion Battery Performance

Most electric bikes use lithium-ion batteries, which are known for their reliability and efficiency. To ensure optimal performance and longevity, follow these tips:

• Fully charge new batteries before first use. Not doing so can reduce total capacity and lifespan.
• Charge the battery immediately after each ride. Letting it fully discharge reduces battery life over time.
• Avoid extreme temperatures. High heat accelerates battery aging; low temperatures help extend battery life.
• Do not charge a cold battery. Wait until it warms up before charging.
• Use only original chargers to prevent damage.

Why Delfast E-Bikes Are Known for Long Ranges

Delfast has always focused on creating high-performance, long-range electric bikes. Models like the Delfast Offroad, Delfast Prime 2.0, and Delfast Top 3.0 were designed with extended range in mind. These bikes are perfect for adventurers who want to cover long distances without worrying about recharging.

How to Calculate the Range of Your Electric Bike

The range of an e-bike is determined by two main factors: battery capacity and riding speed. A higher capacity battery usually means a longer range, while higher speeds tend to decrease it.

To calculate the range, we use watt-hours (Wh). A battery's Wh rating is calculated by multiplying voltage (V) by ampere-hours (Ah). For example:

• A 50V 15Ah battery = 750Wh (50 x 15 = 750)
• A 30V 20Ah battery = 600Wh (30 x 20 = 600)

On average, it takes between 4 and 35 Wh to travel one mile. So, for flat terrain, a 750Wh battery could give you around 187 miles (750 / 4), while a 600Wh battery would provide about 150 miles. In mountainous areas, where energy consumption is higher, the same 750Wh battery might only give you 25 miles (750 / 30).
