For e-bikes, maintaining a speed of around 20 km/h gives a good range.
This recommendation is based on several considerations:
The weight of an e-bike affects its speed and range: The weight of a vehicle directly affects its speed on the road. A heavier vehicle may require more force to accelerate, especially when travelling uphill or when high speeds are required. Lighter vehicles lose less energy while travelling, such as CEAYA's new e-bike, the R8SE, which weighs just 25kg, so it can use its battery energy more efficiently, thus increasing its range.
Power saving and range: Studies have shown that e-bikes consume the least amount of power when the speed is controlled at around 20km/h, which is the most energy efficient state. Therefore, controlling the speed within this range can maximise the range of the e-bike.
Air resistance and motor power: As the speed increases, the air resistance increases accordingly, resulting in the motor needing to output more power to maintain the speed, thus increasing the consumption of battery power. Therefore, controlling the speed reasonably is crucial to extend the range.
Driving habits: In addition to controlling speed, good driving habits are also key to extending range. These include avoiding hard starts, reducing the frequency of sharp braking and stopping, and maintaining a constant speed, etc. These measures can effectively save power and thus extend the range.
To sum up, in order to get a good range, e-bike users should try to control the speed at about 20 km/h and adopt energy-saving driving habits, such as avoiding hard acceleration and hard braking, and keep driving at a constant speed. This not only improves the range, but also protects the battery to a certain extent and prolongs its service life.
