How Fast Do Electric Bikes Go? From Street Legal to High-Performance
Share
Are you wondering how fast do electric bikes go and whether they can truly keep up with the pace of your daily life?
At Electro City Bikes, we know that understanding the speed limits of an electric bike is essential for a safe and legal ride. While there is a firm legal cap for the streets, we also offer a high performance range of electric bikes that push the boundaries of power on private land. Read on to discover the difference between a street legal commuter and an off road beast as we reveal everything you need to know about e-Bike performance.
Whether you are stuck in a gridlock in the heart of the city or looking to conquer a steep mountain trail, the question is always the same: How fast do electric bikes go? Speed is about more than just a number on a screen; it is about the freedom to move, the efficiency of your commute, and the thrill of the open road.
If you have ever wondered if an electric bike can truly replace your car or how it compares to the best electric scooter options on the market, you are in the right place to find out.
The Bottom Line on Speed
In the UK, we follow specific rules to ensure everyone stays safe on the road. For a bike to be considered a standard electric bike UK model, the motor must stop assisting you once you hit 25 km/h, which is about 15.5 mph. While your own leg power can take you faster, the motor is legally required to take a breather at that point.
The Legal Landscape: UK vs. The World
Understanding the rules is the first step to finding the best electric bike for your needs. We take pride in being experts on UK electric cycle regulations so that you can ride with total peace of mind.
- UK and EU Law: Most of our e-Bikes for sale are designed to meet the 250W limit with a 25 km/h speed cap. This allows you to ride on cycle paths and roads without needing a license or insurance.
- The US Standard: Across the Atlantic, they use a tiered system. Class 1 and 2 bikes usually cap at 20 mph, while Class 3 bikes can reach 28 mph with pedal assistance.
- Private Land Use: If you are riding on private property, the rules change. This is where our high-performance models with 750W motors really shine, offering breathtaking acceleration that exceeds standard street limits.

What Affects Your Real-World Speed?
Even with the best electric bikes, your actual speed on the road can vary. At Electro City Bikes, we want you to have a realistic expectation of performance.
- Rider Weight and Cargo: Heavier loads require more energy to move, which can affect how quickly you reach top speed.
- Battery Voltage: A higher voltage system, such as the 48V batteries found in our E26 and M20 models, generally provides more "push" and better performance under pressure.
- Terrain and Incline: Speed will naturally dip on steep climbs. However, models like the E26 are engineered to handle a 30 degree climbing degree, ensuring you do not stall out.
- Tire Pressure and Type: The 4.0 inch fat tires on our folding e-Bikes like the Engine X provide great grip, but they have more rolling resistance than the sleek tires on the N1 Air.
