Legal Speed limits for E-Bikes around the world

Electric bike (e-bike) speed limits are subject to regulations that vary globally, and they often depend on the classification of the e-bike. Different countries and regions have established specific rules to ensure safety and compatibility with existing transportation infrastructure. Here's a general overview, but it's crucial to check local regulations for the most accurate and up-to-date information:

  • In the UK, e-bikes are divided into two categories:

  • EAPCs (Electrically Assisted Pedal Cycles): Maximum assisted speed of 15.5 mph (25 km/h).

  • Speed Pedelecs: Maximum assisted speed of 28 mph (45 km/h).

United States:

  • In the U.S., the Consumer Product Safety Commission (CPSC) sets the federal regulations for e-bikes. Class 1 and Class 2 e-bikes are limited to a maximum assisted speed of 20 mph (32 km/h). Class 3 e-bikes, which are allowed in some states, have a maximum assisted speed of 28 mph (45 km/h).

European Union:

  • In the EU, e-bike regulations are standardized across member states. E-bikes are divided into three classes:

  • Class 1: Maximum assisted speed of 15.5 mph (25 km/h).

  • Class 2: Maximum assisted speed of 15.5 mph (25 km/h) with a throttle.

  • Class 3: Maximum assisted speed of 28 mph (45 km/h).


  • Canada generally follows similar regulations to the EU. Class 1 and Class 2 e-bikes have a maximum assisted speed of 20 mph (32 km/h), while Class 3 e-bikes are capped at 28 mph (45 km/h).


  • In Australia, e-bike regulations vary by state. However, the common theme is that e-bikes are often divided into two classes:

  • Pedal-assist e-bikes: Maximum assisted speed of 15.5 mph (25 km/h).

  • Throttle-controlled e-bikes: Max speed varies by state but is typically 12.5 mph (20 km/h) or 15.5 mph (25 km/h).


Factors Affecting an E-Bike's Speed

Motor Power:

  • The heart of any e-bike is its motor. The power of the motor, usually measured in watts (W), significantly impacts the bike's speed capabilities. Higher wattage generally translates to greater speed potential.

Battery Voltage and Capacity:

  • The battery is the energy source for the electric motor. A higher voltage and capacity allow the motor to generate more power, impacting both acceleration and top speed. However, these factors also influence the overall weight of the bike.

Bike Design and Weight:

  • The design and weight of the e-bike play a crucial role. Sleek, lightweight designs contribute to better aerodynamics and can result in higher speeds. However, factors like the frame material and additional components also affect the overall weight.

Regulations and Classes:

  • Different regions have regulations governing the maximum speed of e-bikes. In many places, there are distinct classes of e-bikes with varying speed limits. Class 1 e-bikes typically assist up to 20 mph (32 km/h), Class 2 includes a throttle with a similar speed limit, and Class 3 e-bikes may assist up to 28 mph (45 km/h). The regulations should be taken into account when you purchase an e-bike with a powerful motor, because as noted above speed restrictions will apply in many countries that limits the e-bike's speed. This means that even the fastest electric bike, will probably come with a speed limiter that doesn't allow it to reach high speeds.


Common Speed Ranges:

While speed capabilities vary among e-bikes, here are general speed ranges for different classes:

Class 1 E-Bikes:

  • Typically assist up to 20 mph (32 km/h). The electric motor assists the rider while pedaling, and the speed is often regulated to comply with local e-bike regulations.

Class 2 E-Bikes:

  • Similar to Class 1 but equipped with a throttle for electric assistance without pedaling. Speed is generally capped at 20 mph (32 km/h).

Class 3 E-Bikes:

  • Pedal-assist e-bikes with the potential to assist riders up to 28 mph (45 km/h). They are subject to specific regulations to ensure safety.

The fastest electric bikes: Recent advancements have seen the emergence of high-speed electric bikes designed for enthusiasts seeking an extra adrenaline kick. Some specialized e-bikes can reach speeds well beyond the traditional limits, often exceeding 30 mph (48 km/h) or more.

Most electric bikes have pedal assistance, where you apply your own pedal power. Even if bikes include electrical assistance, they are still entitled to use designated bike lanes for traditional bikes.


Where to find the best E-Bikes?



The speed of an electric bike is a dynamic interplay of motor power, battery capacity, bike design, and local regulations. Whether you're opting for a class-compliant commuter or exploring the boundaries of high-speed e-bikes, the world of electric cycling offers a diverse range of options to cater to different preferences and riding scenarios. As technology continues to evolve, we can anticipate even more exciting developments in the realm of electric bike speeds, promising a thrilling and efficient future for two-wheeled travel. So, buckle up (or rather, pedal up) as electric bikes redefine our notion of speed and transform the way we move.
