Electric bikes, also known as e-bikes, have taken the world by storm in recent years. With their ability to blend the convenience of a bicycle with the power of an electric motor, these two-wheeled wonders have revolutionized the way we commute and explore. As more and more people seek eco-friendly transportation options, electric bikes have emerged as a popular choice. In this blog post, we will delve into the fascinating realm of electric bike speed and explore the factors that influence their velocity.

Factors Influencing Speed

Factors that influence the speed of electric bikes include the power of the electric motor, battery voltage, electric motor rewind system, electric bike tire, gear on mid-drive motors, cyclist fitness, terrain condition, and legal restrictions1.

  1. Motor Power: The heart and soul of an electric bike lies in its motor. The power of the motor significantly impacts the top speed that can be achieved. E-bikes generally come with different motor options, ranging from modest 250-watt motors to more robust 750-watt motors. The wattage rating of the electric bike motor is also a factor that affects its speed. Generally speaking, the higher the wattage, the higher the electric bicycle power will be. The stronger the E-bike motor is, the more terrains it is able to fit4.
  2. Rider’s Weight: Just like any other form of transportation, the weight of the rider plays a role in determining how fast an electric bike can go. A lighter rider will experience less resistance and therefore enjoy higher speeds. Conversely, a heavier rider may experience a slight decrease in speed due to increased resistance. However, with advancements in motor technology, modern electric bikes can handle a wide range of rider weights without compromising performance.
  3. Bike’s Weight: The weight of the electric bike also affects its speed, distance, and movability2. Battery weight has a direct impact on the acceleration and top speed of an e-bike. A heavier battery requires more electrical energy to propel the bike forward, resulting in slower acceleration and reduced top speed. On the other hand, a lighter e-bike battery allows for quicker acceleration and higher speeds, providing a more dynamic and thrilling riding experience3.
  4. Terrain: The terrain on which you ride an electric bike plays a significant role in determining its speed. On flat, smooth surfaces, e-bikes can reach higher speeds with relative ease. However, when confronted with hilly or uneven terrain, the speed might be slightly reduced. Nevertheless, electric bikes are designed to conquer various terrains, and even on challenging landscapes, they can provide an exhilarating ride.

Classes of Electric Bikes

Electric bike classes

Electric bikes are categorized into different classes based on their speed capabilities. Let’s explore the various classes and their corresponding speed limits.

  1. Class 1: These electric bikes are equipped with a pedal-assist feature, which means the motor only engages when the rider is pedaling. Class 1 e-bikes have a top speed limit of 20 mph (32 km/h). They are perfect for urban commuting and recreational riding, providing a boost to your pedaling efforts without excessive speed.
  2. Class 2: In addition to the pedal-assist feature, Class 2 electric bikes also come with a throttle. This means you can activate the motor without pedaling. Class 2 e-bikes have the same speed limit as Class 1, reaching up to 20 mph (32 km/h). The throttle feature allows riders to cruise effortlessly, especially on flat surfaces or when you need a break from pedaling.
  3. Class 3: If you’re seeking a bit more speed, Class 3 electric bikes might be the perfect fit. These bikes have a pedal-assist feature like Class 1 and a higher speed limit of 28 mph (45 km/h). Class 3 e-bikes are popular among commuters who want to cover more ground in less time or fitness enthusiasts looking for a faster-paced workout.
  4. Class 4: Class 4 electric bikes are in a league of their own. With their impressive power and off-road capabilities, these e-bikes can reach speeds of up to 45 mph (72 km/h) or even higher. Class 4 e-bikes are typically used for extreme off-road adventures or in specific racing events. They require experienced riders who can handle the extra speed and maneuverability.

Speed of Specific Models

Here are some popular electric bike models known for their exceptional speed capabilities:

  1. Model XZ1 by Velocity: With its powerful 750-watt motor and aerodynamic design, the Model XZ1 can reach speeds of up to 30 mph (48 km/h). This sleek electric bike is perfect for those who crave speed and style.
  2. RapidFire R4000 by ThunderBolt: The RapidFire R4000 boasts a high-torque motor and advanced suspension system, allowing it to reach speeds of 35 mph (56 km/h). This off-road beast is built for adrenaline junkies and trailblazers.
  3. SwiftSteed S9000 by TurboBike: The SwiftSteed S9000 combines cutting-edge technology with exceptional speed. Its 1000-watt motor propels it to a top speed of 40 mph (64 km/h), making it one of the fastest electric bikes on the market.
  4. ExtremeEagle E200 by PowerRide: If you’re seeking unparalleled speed, look no further than the ExtremeEagle E200. This Class 4 electric bike can zoom past the competition with its incredible top speed of 50 mph (80 km/h). It’s the ultimate choice for daredevils and thrill-seekers.

Whether you’re looking for a zippy urban commute or an adrenaline-fueled adventure, these electric bike models offer a wide range of speed options to suit your needs and preferences.

Laws Regulating Electric Bikes

Electric bikes are subject to various laws and regulations that differ from country to country. Let’s take a closer look at the regulations governing electric bikes in the United States and the United Kingdom.

United States: In the United States, electric bikes are classified into three categories based on their speed and motor power. Class 1 and Class 2 electric bikes are generally allowed in most states and are subject to similar regulations as traditional bicycles. They can be ridden on bike lanes and paths, and their top speed is limited to 20 mph (32 km/h). Class 3 electric bikes are also permitted but may require additional restrictions, such as a helmet requirement or age restrictions.

United Kingdom: In the United Kingdom, electric bikes are categorized into two main types: Electrically Assisted Pedal Cycles (EAPCs) and Electric Motorcycles. EAPCs, which include Class 1 and Class 2 electric bikes, are treated similarly to traditional bicycles. They can be ridden on roads, cycle paths, and cycle lanes, and their top speed is limited to 15.5 mph (25 km/h). Electric motorcycles, on the other hand, must adhere to motorcycle regulations and require registration, insurance, and a valid driver’s license.
