Whether you call it an e-bike, electric bicycle, or ebike, one thing is clear — these vehicles are changing the way we move. More people are choosing e-bikes for daily commutes, leisure rides, and even long-distance travel. One of the most common questions when considering an e-bike is: how far can it go on a single charge? This is where range becomes a critical factor in your decision.

Currently, the longest-range e-bike available is from Delfast. Their model holds the Guinness World Record for the furthest distance on a single charge — an impressive 228 miles. The latest version, the Top 3.0i, has pushed this even further with a record-breaking 232 miles thanks to software upgrades. But what does that mean in real-world conditions? Can you estimate the range based on battery specs like volts and amp hours?

The answer lies in several key components: the battery, motor, controller, and overall system efficiency. These elements work together to determine your speed, pedal assist levels, and even give an estimated range. However, the main determinant of range is the battery's capacity, measured in volts and amp hours.

The Voltage of the Battery

Voltage (measured in volts) plays a big role in power and speed. Most e-bikes use 36V or 48V batteries, which are cost-effective but limited in performance. Lower voltage means less power, especially when climbing hills or riding at higher speeds. For a more powerful ride, look for models with 52V or even 72V systems.

Delfast’s top model, the Top 3.0i, uses a 72V lithium-ion battery paired with a 3,000W motor. This combination not only makes it one of the fastest e-bikes in the world but also gives it the longest range. A high-voltage system provides better efficiency and more power, making your ride more enjoyable and longer-lasting.

The Amp-Hours Value of a Battery

Amp-hours (Ah) measure the battery’s capacity — essentially how much energy it can store. A higher Ah value means a longer range. For example, a 10Ah battery might last around 20 miles, while a 48Ah battery could push the range well beyond 200 miles.

But there’s a trade-off. High-capacity batteries are larger, heavier, and more expensive. If you’re looking for a long-range e-bike, consider the size, weight, and cost before making a purchase. It’s important to match the battery capacity to your needs — if you're commuting short distances, a smaller battery may be sufficient.

Batteries for Long-Range e-Bikes

To achieve a long range, your e-bike must have a high-capacity battery. Lithium-ion batteries are the standard, but they come in different sizes. A 20Ah battery with 52V can take you up to 100 miles, depending on conditions. If you want more range, look for models with 48Ah or higher, like Delfast’s Top 3.0i.

When choosing a battery, keep in mind factors like size, weight, and price. A large battery might be great for long trips, but it could be difficult to carry or install. Consider your usage and lifestyle before deciding on the best option for you.

The Leader of the Pack for Range

Delfast’s Top 3.0i is a game-changer. With a 72V 48Ah lithium-ion battery, it delivers a top speed of 50 mph and an incredible range of 200+ miles. Whether you're exploring the countryside, commuting, or just looking for a fun ride, this bike offers unmatched performance and reliability.

It’s perfect for off-road adventures and daily use. If you're looking for a versatile, high-performance e-bike that can handle any terrain, the Top 3.0i is the one to go for. Don’t miss out on the future of electric mobility.
