In recent years, the world has witnessed a huge rise in the popularity of electric bikes. More people are choosing e-bikes because they’re eco-friendly, cost-effective, and easy to use. The pandemic also played a role—many turned to cycling as a safe, healthy way to get around during lockdowns.

Modern e-bikes come in various models with different speeds, power, and prices, making it easier for riders to find one that suits their needs. But how fast can an e-bike actually go? And what are the legal limits?

Are There Any Legal Restrictions?

Before riding, it's important to understand the laws in your country or state. In the U.S., for example, e-bike regulations vary by state. Some allow speeds up to 20 mph, while others go up to 30 mph. Most states classify e-bikes into three categories:

• Class 1: Pedal-assist only, up to 20 mph (32 km/h)
• Class 2: Throttle-controlled, up to 20 mph (32 km/h)
• Class 3: Pedal-assist up to 28 mph (45 km/h)

All classes may have motors up to 750W. However, many states don’t have clear definitions, so manufacturers often limit speeds to 20 mph to stay on the safe side. If you buy a bike that goes over 20 mph, it might be classified as a motor vehicle, which comes with additional requirements.

Do I Need a License?

If your e-bike exceeds 20 mph using just the motor, you may need a moped license. This includes registration, a license plate, and a state decal. Without these, your bike might not be considered street-legal. However, if you only ride it on private property, you’re usually fine.

Age Restrictions

You must be at least 12 years old to ride an e-bike, provided it meets certain criteria. For example, a 20 mph e-bike with a 500W motor is generally allowed. If the bike is more powerful, like a motorcycle, it may fall under stricter rules.

Maximum Speed of E-Bikes

Many manufacturers offer a wide range of speeds, but some models are built for speed. Delfast, for instance, produces one of the fastest e-bikes in the world—the Delfast TOP 3.0, which can reach up to 50 mph. It’s perfect for long trips and tough terrain. Some companies include speed limiters to comply with laws, but there are ways to remove them.

How to Speed Up Your E-Bike

1. Keep it light. Avoid carrying extra weight, as it slows you down.
2. Stay seated. Standing reduces efficiency and speed.
3. Check tire pressure regularly. Under-inflated tires increase resistance.
4. Avoid throttling when the battery is low. It affects performance.
5. Replace tires when needed. High-speed tires wear out faster.

Derestricting Your E-Bike

Some riders choose to "derestrict" their e-bikes, meaning they remove speed limits. However, this can void the warranty and may not be legal in all areas. It increases speed but doesn’t boost power.

The Fastest Electric Bike in 2020

Delfast continues to push the boundaries of e-bike technology. Their TOP 3.0 model features a 5,000W hub motor and can reach 50 mph. With a 72V, 48Ah battery, it offers up to 200 miles of range on a single charge. In October, Delfast announced a new strategy focusing on the TOP line, phasing out older models like the Prime, which once held the Guinness World Record for longest range—370 km on a single charge.

Currently, there’s a big sale on previous models with discounts of up to $900. Don’t miss this chance to own one of the most powerful e-bikes on the market!
