Whether you call it an e-bike, electric bicycle, ebike, or electric bike, one thing is clear: these vehicles are changing the way we move. More people than ever are choosing electric bikes for commuting, recreation, and even long-distance travel. But one of the most common questions when considering an e-bike is: how far can it go on a single charge?

The answer isn’t straightforward. It depends on several factors, including battery capacity, motor power, terrain, rider weight, and riding style. The current leader in range is Delfast, with its Top 3.0i model holding the Guinness World Record for the longest-range e-bike. With a top range of 232 miles on a single charge, this bike pushes the limits of what’s possible.

But how does that translate to real-world conditions? What should you look for when evaluating the range of an e-bike? Let's break it down.

The Role of Battery Voltage

The voltage of an e-bike’s battery plays a key role in both performance and efficiency. Most consumer models use 36V or 48V batteries, which offer decent power for daily use. However, if you're looking for more speed and longer range, higher voltages like 52V or 72V become important.

A 72V system, like the one found in Delfast’s Top 3.0i, delivers more power and better efficiency. This means the bike can maintain higher speeds while using energy more effectively, resulting in a longer range. While higher-voltage batteries tend to be pricier, they offer a much smoother and more powerful ride—especially when climbing hills or riding at higher speeds.

Understanding Amp-Hours (Ah)

If voltage determines speed and power, then amp-hours (Ah) determine how long the battery will last. Ah measures the total amount of energy stored in the battery. A higher Ah rating means the battery can supply more current over time, leading to a longer range.

For example, a 20Ah battery can power a 10A motor for two hours, while a 48Ah battery can do the same for nearly five hours. That’s why many long-range e-bikes use high-capacity batteries, often 48Ah or more. These batteries are larger and heavier, but they’re essential for those who want to ride farther without recharging.

Choosing the Right Battery for Your Needs

When selecting an e-bike, it's important to consider not just the specs, but your actual usage. If you're commuting short distances, a 10Ah–20Ah battery may be sufficient. But for longer trips or off-road adventures, you’ll need something more robust.

• Size: High-capacity batteries take up more space. Make sure your bike frame can accommodate them.
• Weight: Larger batteries mean more weight. If you need to carry your bike up stairs, this is a key factor.
• Cost: High-capacity batteries are more expensive. Decide whether the extra range is worth the investment based on your needs.

Delfast’s Top 3.0i – The Ultimate Long-Range E-Bike

Delfast’s Top 3.0i is designed for those who want maximum performance and range. It features a 72V 48Ah lithium-ion battery, a 3,000W motor, and a top speed of 50 mph. This combination allows for an impressive range of up to 232 miles on a single charge.

Whether you're exploring the countryside, commuting across the city, or simply looking for a fun ride, the Top 3.0i offers versatility and power. It’s perfect for those who want to push the boundaries of what an e-bike can do.
