Electric bikes, or e-bikes, are gaining immense popularity worldwide. There are several compelling reasons behind this trend. The pedal-assist feature of e-bikes makes cycling accessible to a broader audience. People who might not consider themselves physically fit can now enjoy long rides with ease. Additionally, e-bikes serve as a practical and healthy commuting solution in urban areas plagued by traffic congestion.

A common question among those considering purchasing their first e-bike is: how fast can an electric bike go? Many are also curious about whether the speeds these bikes can reach fall within safe and legal limits. While the answers to these questions aren't always straightforward, it's important to note that e-bikes in the US are generally allowed to reach speeds of up to 20 mph (32 km/h), whereas in Europe, the limit is typically 15.5 mph (25 km/h). These legal caps are set by regional regulations, but some e-bikes can go faster depending on the type of motor they use.

In this article, we'll delve deeper into the topic of speed. We'll explore some technical factors that influence it. As an e-bike owner, staying informed about local laws governing the use of such vehicles is crucial. Adhering to legal speed limits ensures both safety and enjoyment during your rides.

The Role of Motor Power in Determining Speed

When riding an e-bike, you rely on the motor for assistance. Naturally, this means you can expect to achieve speeds higher than what you could reach through manual pedaling alone. On average, cyclists can pedal between 7.5 and 9.5 mph (12-15 km/h) using just their leg power. Consequently, an e-bike can easily double or even triple that speed.

The speed of an e-bike hinges largely on the electric motor. Under similar conditions, such as flat terrain, a more powerful motor will result in higher speeds. However, the relationship between electric power and speed isn't linear. Consider the following approximate speed values on flat terrain:

• A 250W motor can yield speeds of up to 20 mph.
• A 500W motor can reach speeds of up to 25 mph.
• A 750W motor can reach speeds of up to 28 mph.
• A 1000W motor can reach speeds of up to 35 mph.
• A 1500W motor can reach speeds of up to 40 mph.

It's worth noting that 250W is the most commonly used motor power for e-bikes, ensuring compliance with legal speed limits in many regions. However, not all e-bikes are designed to reach these maximum speeds.

The Classification of E-Bikes

For regulatory purposes, electric bikes are categorized into three distinct classes. However, this classification system hasn't been uniformly adopted across the US. In certain states, e-bikes are treated similarly to traditional bicycles, requiring no special licensing or age restrictions for riders. Conversely, other jurisdictions impose regulations akin to those for motor vehicles.

Class 1: Pedal-Assist Only Up to 20 mph

These vehicles offer pedal assistance only and cease providing help once the rider reaches 20 mph.

Class 2: Pedal-Assist and Throttle Up to 20 mph

This type of e-bike also tops out at 20 mph but includes a throttle mode. The most common types of throttles are twist or thumb throttles located on the handlebars. Activating the throttle propels the bike without the need for pedaling, similar to riding a motorcycle. Despite having a throttle, class 2 vehicles are not the fastest e-bikes available.

Class 3: Pedal-Assist Only Up to 28 mph

Functioning much like class 1 e-bikes, class 3 models can reach speeds of up to 28 mph. This extra speed allows riders to cover distances more quickly. Although you may not always need to ride at maximum speed, it's reassuring to have the capability when needed.

Race Track Mode: Unrestricted Speed

If you're a speed enthusiast, you can experience the thrill of high-speed riding on a race track or private property with an e-bike equipped with a race track mode. Some e-bikes, like the Delfast Top 3.0, allow the use of throttle to reach the full potential speed of the electric motor.

Forbes has named the Delfast Top 3.0 as the fastest electric bike globally. With a top speed of 50 mph (80 km/h), it surpasses all competitors. This remarkable achievement is due to its powerful 3000W motor and advanced battery technology.

The Delfast Top 3.0 is versatile enough to serve as both an off-road adventure vehicle and a reliable commuter. Its race track mode provides pedal assistance beyond the standard 28 mph limit, while its pedal-assist mode offers options for lower speeds.

Choosing Between Low and High Speed

For leisurely rides, cruising at a slower pace can be enjoyable. Exploring new trails or simply enjoying the scenery at your own rhythm is a delightful experience. However, there are times when you may need to move faster, such as when running late for work. In such scenarios, the ability to go at top speed becomes invaluable.

If you're passionate about speed, investing in a high-performance e-bike is ideal. Keep in mind, though, that riding at maximum speed on public roads might not always be feasible due to legal restrictions. Therefore, a versatile e-bike like the Delfast Top 3.0 is an excellent choice. It offers a wide range of speed options, making it suitable for various activities, from casual cycling to race track adventures.
