A 36V electric bike refers to an e-bike that operates using a 36-volt battery. The battery’s voltage is a key determinant in the bike’s overall power, speed, and performance.
It is crucial to understand that while the voltage of the battery plays an important role, other elements such as the motor power, the bike’s weight, and the terrain all contribute to the final top speed.
Motor Power and Speed Limits
The motor's power plays a pivotal role in determining the top speed of an electric bike.
Most 36V e-bikes come with motors that range between 250W to 500W. The 250W motor is typically sufficient for urban commuting and light off-road trails, whereas a 500W motor provides better speed and power for steeper inclines and longer rides.
In general, a 36V electric bike with a 250W motor can achieve a top speed of around 15 to 20 miles per hour (24 to 32 km/h), while a 500W motor can push the bike to speeds of 20 to 28 miles per hour (32 to 45 km/h), depending on various factors.
Battery Capacity and Speed Performance
While voltage directly correlates to the motor's power, battery capacity (measured in amp-hours, or Ah) also plays a role in determining how efficiently an electric bike can maintain high speeds.
A higher amp-hour rating provides more energy, allowing the motor to perform better over longer distances. In the case of a 36V battery, a 10Ah battery offers a good balance of speed and endurance, allowing the motor to run at optimal performance over longer periods without overheating.
If you want consistent high-speed performance, it’s important to pair a 36V battery with a motor that matches its capacity.
This ensures that the bike doesn’t underperform or experience excessive strain when pushing towards its speed limits.

Factors That Affect the Speed of a 36V Electric Bike
The top speed of a 36V electric bike is influenced by multiple factors beyond the motor and battery.
Terrain and Surface
The type of terrain you ride on plays a significant role in determining the actual speed you can achieve.
On flat, smooth surfaces, a 36V electric bike can reach its maximum speed with ease.
When riding uphill or on rough trails, the bike may experience a reduction in speed due to the increased load on the motor and the effort required to maintain momentum.
Rider Weight
The rider’s weight is another critical factor. Heavier riders put more stress on the motor, which can affect both the speed and the range of the bike.
Lighter riders may notice better performance, with the bike reaching higher speeds more easily. It’s recommended to consider your weight when selecting the motor power for an electric bike to achieve optimal speed and efficiency.
Motor Controller and Legal Limitations
Many electric bikes come equipped with speed limiters or governors that restrict the bike’s top speed to comply with local laws and regulations.
In many regions, e-bikes are limited to a maximum speed of 20 miles per hour (32 km/h) for legal road use, especially for bikes classified as Class 1 e-bikes.
Certain bikes can be upgraded or modified to remove these limitations, allowing riders to unlock higher speeds.
How Fast Can a 36V Electric Bike Go on Different Terrains
Flat Roads
On a flat surface, a 36V e-bike with a 250W motor can comfortably reach speeds of around 15 to 20 miles per hour (24 to 32 km/h).
For 500W motors, the speed can range between 20 to 28 miles per hour (32 to 45 km/h), depending on factors like rider weight, battery charge, and bike design.
Smooth, paved roads offer the least resistance, allowing the bike to perform optimally.
Uphill Riding
When riding uphill, the speed of a 36V electric bike will be noticeably reduced due to the added resistance.
A 250W motor may struggle to reach more than 10 to 15 miles per hour (16 to 24 km/h) on a moderate incline, while a 500W motor may reach speeds of 12 to 18 miles per hour (19 to 29 km/h), depending on the grade of the hill and the weight of the rider.
Off-Road Trails
Off-road terrain, which includes dirt paths, gravel, and muddy trails, introduces additional challenges for an electric bike.
The bike’s speed will generally be lower than on paved roads due to the increased rolling resistance.
A 36V e-bike may achieve speeds of around 10 to 15 miles per hour (16 to 24 km/h) on rough trails, but this can vary depending on the specific trail conditions and the bike’s suspension.
36V vs Other E-Bike Voltages
24V E-Bikes
These bikes generally have a top speed of around 12 to 18 miles per hour (19 to 29 km/h), making them slower than their 36V counterparts. 24V e-bikes are best suited for light commutes or casual riders on flat terrain.
36V E-Bikes
A 36V e-bike typically reaches speeds between 15 to 20 miles per hour (24 to 32 km/h) depending on the motor power and terrain. This makes it an ideal choice for daily urban commuting, light trail riding, and those looking for a balance of performance and affordability.
48V E-Bikes
With 48V batteries, these bikes can reach speeds of 25 to 30 miles per hour (40 to 48 km/h). 48V e-bikes offer a significant performance boost over 36V models, providing more torque for climbing hills and better efficiency for longer rides. Riders seeking a faster, more powerful bike for varied terrains often opt for the 48V.
Conclusion
A 36V electric bike can achieve impressive speeds, typically ranging from 15 to 28 miles per hour (24 to 45 km/h) depending on factors such as motor power, battery capacity, terrain, and rider weight. While it might not be as fast as 48V e-bikes, it offers an ideal combination of speed, efficiency, and range for urban commuting and light recreational riding.
FAQs
Can I go faster than 28 mph on a 36V e-bike?
In most cases, no. Most 36V e-bikes are limited by motor capacity and legal restrictions to a maximum speed of around 28 miles per hour. However, some bikes can be modified to remove speed restrictions.
How long does the battery last on a 36V electric bike?
The battery life of a 36V e-bike depends on the battery capacity and the type of usage. Generally, you can expect a range of 20 to 50 miles per charge, depending on terrain and riding style.
Is a 36V e-bike suitable for climbing steep hills?
A 36V e-bike with a 500W motor can handle moderate hills fairly well, but for steeper inclines, you may want to opt for a more powerful bike, like those with 48V batteries or 750W motors.
