Previously on the Delfast blog, we discussed how to mount a camera on an electric bike. This article focuses on calculating the range of electric bikes and what factors influence it. So, how far can you ride on a single charge? That depends on several variables.

The longest range for an electric bike can reach up to 200-250 miles. These bikes are typically designed for long-distance rides and are equipped with 3kWh batteries. Standard electric bikes with smaller batteries (around 400-500Wh) can cover distances of about 60-75 miles without recharging. City-commuter electric bikes generally offer a range of 30-40 miles per charge.

Back in 2017, Delfast made waves in the e-bike industry when the Delfast Prime traveled 367 kilometers (228 miles) on a single charge, setting a new benchmark for long-distance electric biking.

Several factors can significantly impact the range of your electric bike:

• Weather conditions: On sunny days, the range tends to be about 15% longer compared to rainy days.
• Tire pressure: Soft tires are great for city roads but don't perform well on mixed or mountainous terrains.
• Rider's weight and extra luggage can lead to faster battery depletion.
• Battery type: Low-power batteries can be affected by frequent starts and stops.
• The weight of the bike's motor and battery can reduce the overall range. If you're planning a long trip without access to charging points, consider this factor.
• Your riding style—how hard you pedal and your speed—also plays a role in battery consumption.
• Terrain: Riding on flat surfaces offers better efficiency compared to mountainous areas.

What Kind of Range Can You Expect from Lithium-Ion Batteries?

Lithium-ion batteries are the most commonly used for electric vehicles due to their convenience and performance. To ensure these batteries last as long as possible, follow these guidelines:

• Before using a new lithium-ion battery, charge it fully. Many people mistakenly use their e-bike batteries right after purchase, which can reduce the battery's lifespan and total capacity.
• After discharging, recharge the battery immediately. Constantly bringing the battery to full discharge can damage it and shorten its life.
• Avoid exposing lithium-ion batteries to high temperatures. Heat accelerates battery aging. The optimal operating temperature should be kept between 68-77°F (20-25°C). Even a slight increase in temperature can drastically reduce the battery's lifespan.
• Low temperatures and partially discharged batteries tend to have longer lifespans.
• Never charge a battery that is still very cold. If your bike has been ridden in freezing conditions, wait until it warms up before charging it.
• Always use the original charger provided with your electric bike.

Why Delfast E-Bikes Stand Out with Long-Range Options

Delfast bikes were designed with long-distance travel in mind. Models like the Delfast Offroad, Delfast Prime 2.0, and Delfast Top 3.0 have consistently impressed users with their impressive ranges on a single charge.

Calculating the Range of Your Electric Bike

The range is determined by the battery capacity and your riding speed. Higher capacity means more range, while faster speeds usually result in shorter distances before needing a recharge. Let’s break it down using watt-hours (Wh) to measure battery capacity. This can help you estimate how far you can ride before running out of juice.

An e-bike battery is measured by its voltage (V) and ampere-hours (Ah). To calculate the Wh, multiply the voltage by the ampere-hours. For instance:

A 50V 15Ah battery has a capacity of 750Wh (50 x 15 = 750).

A 30V 20Ah battery has a capacity of 600Wh (30 x 20 = 600).

On average, an e-bike battery provides about 1 mile for every 4-35Wh of energy. For flat terrain, energy consumption is minimal, so the range is higher. Let’s assume 4Wh per mile:

750 / 4 = 187.5 miles.

600 / 4 = 150 miles.

For mountainous terrains, energy consumption can be much higher, around 30Wh per mile:

750 / 30 = 25 miles.

600 / 30 = 20 miles.

Delfast Software:

Delfast electric bikes are packed with smart features. Our fans love us for our powerful motors and impressive range, but Delfast offers much more than just specs. We’ve integrated a suite of apps into our bikes, including anti-theft systems, remote start, color displays, start-stop buttons, Bluetooth connectivity, alarms, and motor blocking.
