How Fast Can An eBike Go?

Electric bike (e-bike) speed can vary depending on the class of the e-bike, the power of the electric motor, the capacity of the battery, the weight of the rider and any cargo, and the terrain. In this article, we will explore the different speed classes of e-bikes, the laws regulating e-bike speeds in the USA, and how various factors can affect the speed of an e-bike.

The speed of an e-bike is determined by the amount of power being provided by the electric motor as well as the rider's own pedaling. Generally speaking, e-bikes equipped with pedal assist can reach speeds of 20-28 mph, depending on the model and the level of assistance chosen by the rider. Without the pedal assist, as with any other bicycle, you can go as fast as you can cycle.

E-Bike Classifications

E-bikes are classified into three classes based on their top speed and the type of power assistance they provide. These classifications are used in the USA, Canada, and many other countries to regulate the speed and power of e-bikes:

Class 1: This group includes eBikes that do not have a throttle and are powered strictly by pedaling or assisted pedaling. Additionally, the maximum motor-assisted speed for Class 1 eBikes is 20 MPH. Class 1 eBikes are generally allowed on bike paths and bike lanes that are shared with traditional, non-assisted bikes.

Class 2: This group follows the same 20 MPH motor-assisted limit as Class 1, but Class 2 eBikes have a throttle in addition to or in place of pedal assistance. As with Class 1 eBikes, you can generally ride them in the same places as an analog bike.

Class 3: The last group of eBikes under this class system has a maximum motor-assisted speed of 28 MPH. Typically this top speed is only allowed to be achieved with assisted pedalling, with any throttle option only allowing up to 20 MPH.

It's worth noting that some countries may have different classification criteria or different speed limits for e-bikes.

Factors Affecting eBike Speed

The speed of an e-bike can be affected by various factors, including:

Power of the electric motor

The power of the electric motor is measured in watts and it plays a significant role in determining the speed of an e-bike. Generally speaking, the higher the wattage of the motor, the faster the e-bike can travel. 

However, it's also important to keep in mind that the more powerful the motor, the more energy it will consume and the quicker the battery will drain. This means that an e-bike with a high-powered motor may be able to travel at faster speeds, but it may also have a shorter range on a single charge.

Capacity of the battery

The capacity of the battery is measured in amp-hours (Ah) and it also plays an important role in determining the speed and range of an e-bike. The larger the battery, the more energy it can store and the farther the e-bike can travel before needing to be recharged.

However, it's worth noting that larger batteries also add more weight to the bike and can reduce the overall speed and performance.

Weight of the rider and cargo

The weight of the rider and any additional cargo on the e-bike can also affect its speed. An e-bike will be slower when carrying a heavier load as the extra weight will cause the motor to work harder and consume more energy.

Additionally, the rider's own weight can also play a role, as a heavier rider will require more power to maintain a certain speed.


The terrain can also affect the speed of an e-bike. Riding on flat ground will consume less energy than riding up a steep hill, as the e-bike's motor will have to work harder to overcome the resistance of the uphill slope.

Additionally, riding on gravel or other off-road terrains can also cause the e-bike to slow down, as the extra resistance and potential for loss of traction can impede the speed of the e-bike.


In the USA, e-bike laws are regulated at the state level, so the rules can vary depending on the state you're in. However, most states classify e-bikes into the three classes mentioned above and regulate their speed accordingly. Some states also have additional regulations in place, such as requiring e-bike riders to wear helmets or limiting the use of e-bikes to certain areas or trails.

It's important to check the laws in your state and municipality before buying or riding an e-bike, as breaking the laws can result in fines or impoundment of the bike. People For Bikes is a great resource for state-by-state electric bike laws.
