Have you ever come across the phrase, "gotta go fast"? If that sounds familiar, you likely have a deep appreciation for speed.
Even if it doesn't ring a bell, chances are you're drawn to the excitement and adrenaline that speed brings – after all, that's probably what led you here in search of the world’s fastest electric bike.
You’re in the right place. At ENGWE Bikes, we take pride in discovering—and designing—some of the best electric bikes to match your performance needs. Read on to explore what makes the world’s fastest electric bike so extraordinary.
How Fast is an Electric Bike?
Most electric bikes can reach speeds of around 15 to 20 miles per hour (24 to 32 kilometers per hour) with motor assistance. This is the typical cruising speed for most standard models.
Some more powerful electric bikes are capable of going up to 28 mph (45 kilometers per hour) or even faster, especially performance or off-road versions. However, these fast e bicycle models are usually designed for experienced riders or specific terrains.
Factors That Affect the Speed of an Ebike
It’s a common misconception that only the build of an electric bike can determine how fast it can go. While it’s very important, there are many other factors affecting the speed of a fast electric cycle. These include:
Motor Power – The higher the motor wattage, the more speed the bike can generate. A stronger motor gives better acceleration and helps maintain higher speeds – especially uphill or with heavy loads.
Battery Voltage – A higher battery voltage (like 36V or 48V) can push more power to the motor, which supports faster riding. But it also depends on how efficiently the motor and battery work together.
Pedal Power – Your own pedaling effort matters – especially on pedal-assist bikes. The harder or faster you pedal, the more the motor assists, which helps you reach top speeds faster.
Rider’s Weight – A heavier rider (or added cargo) makes the bike work harder, which can slightly reduce speed. It’s particularly true when climbing hills.
Terrain & Wind – Smooth, flat roads let you ride faster. Hilly or rough terrain slows you down, even with motor help. Similarly, riding into strong wind or sitting upright increases air drag, which can slow the bike.
Tire Type – Wider or under-inflated tires create more resistance. Meanwhile, thin and properly inflated tires help you roll faster on smooth roads.
What’s the Fastest an Electric Bike Can Go Legally?
Legally, the fastest most electric bikes can go depends on local regulations. In many places like the United States, the legal speed limit depends on the following classes:
Class 1 & 2: Max motor-assisted speed is 20 mph (32 kilometers per hour)
Class 3: Pedal-assist only, up to 28 mph (45 kilometers per hour)
Anything faster is usually considered a moped or motorbike that requires a license, registration, and possibly insurance.
However, in most European Union countries, e-bikes are legally limited to:
-
15.5 mph (25 kilometers per hour) motor-assisted speed
-
250-watt motor limit
If the bike goes faster than 25 kilometers per hour or uses a stronger motor, it is no longer considered a bicycle. Instead, it becomes a speed pedelec (also called an S-pedelec). These can reach up to 45 kilometers per hour (28 mph) and require:
-
An insurance
-
A helmet
-
License plates
-
Rider age restrictions (varies by country)
Countries like Germany, France, the Netherlands, and Italy follow these EU-wide standards, though some local rules may add extra requirements (e.g., where S-pedelecs can ride).
