The right tire pressure is of great importance for your electric bike. It not only determines how comfortable you ride, but also affects the range, safety and lifespan of your tires.
In this blog we cover everything you need to know about tire pressure , including practical tips and answers to frequently asked questions.
What is tire pressure and why is it important?
Tire pressure, measured in bar or psi, refers to the amount of air in your bike tires. It seems like a small detail, but it plays a big role in:
- Ride comfort: a tire that is too hard feels uncomfortable, while a tire that is too soft is heavy to pedal.
- Efficiency: the correct pressure reduces rolling resistance and extends the range of your electric bicycle.
- Grip and safety: correctly inflated tires provide more stability, especially in rainy weather.
- Service life: optimal pressure prevents unnecessary wear on your tyres and saves costs.
General guidelines for tire pressure
The ideal tire pressure varies by type of bike and use. Here are some guidelines:
- City bike (e-bike): 3.0 – 4.0 bar
- Mountain bike: 1.8 - 3.0 bar
- Racing bike: 6.0 - 8.0 bar
- Fatbike: 0.5 - 1.5 bar
The recommended pressure for your tires is usually stated on the sidewall of the tire. The recommended tire pressure for the Levante E4 is 3.0 – 3.5 bar.
Factors that influence correct tire pressure
- The type of tire
Fat tires require lower pressure than thin tires. Wide tires, such as on a mountain bike, have more air volume and provide stability at lower pressure. Thin road bike tires, on the other hand, require higher pressure to ensure efficiency and speed.
- Weight
The total weight of the rider, luggage, and the bike itself affects tire pressure. A heavier load means that the tires need more pressure to prevent deformation. Add about 0.1 to 0.2 bar extra for every 10 kg of extra weight.
- Driving surface
- Asphalt: On paved roads, you can increase the pressure slightly to reduce rolling resistance. This promotes a smooth and efficient ride.
- Gravel, sand, or mud: Here tires perform better with lower pressure, as this provides more grip and shock absorption.
- Weather conditions
In rainy or slippery conditions, you can reduce the pressure slightly to improve grip. However, always be sure to stay within the recommended range.
- Driving style
A sporty rider will benefit from a higher pressure for speed and efficiency, while recreational cyclists want more comfort and will opt for a slightly lower pressure.
How do you measure and adjust tire pressure?
Measuring and adjusting tire pressure is easy with the right tools. Use a bicycle pump with a built-in pressure gauge or a separate tire pressure gauge. Follow these steps:
- Check the valve type: e-bikes usually have Presta, Schrader or car valves. Make sure your pump is compatible with your valve.
- Connect the pump: Place the pump firmly on the valve, making sure no air escapes.
- Measure the current voltage: check if the pressure is within the recommended range.
- Adjust the tension: pump in or out air until the desired tension is reached.
Why is regular checking important?
The tire pressure of your bike changes due to natural air loss and temperature differences. Regularly checking prevents discomfort and extends the life of your tires. Here are some recommendations:
- Monthly check: keep your tire pressure consistent.
- Extra control for long journeys: this way you can avoid unexpected problems on the road.
- Pay attention to seasonal differences: pressure can drop in cold temperatures. Therefore, check your tires more often in winter.
How does tire pressure affect range?
Low tire pressure increases rolling resistance, which forces the engine to work harder and drains the battery faster. This significantly reduces the range. With the right pressure, you can get up to 15% more kilometers from your battery.
Common mistakes with tire pressure
- Over-inflated tires: This results in less grip and comfort, especially on rough roads or in wet conditions.
- Under-inflated tires: This increases the risk of punctures and makes cycling unnecessarily difficult.
- Irregular control: air loss occurs gradually, which can cause your tension to become too low without you noticing.
- Using the wrong valve: Make sure you have a pump that is compatible with your valve type.
Tips for optimal tire pressure
- Invest in a good bicycle pump: a pump with an accurate pressure gauge is essential.
- Experiment with tension: adjust the tension and find out what works best for your riding style and environment.
- Keep your tires clean: Dirt can accelerate wear and affect pressure.
- Check for wear regularly: cracks, bumps or other damage can reduce the performance of your tires.
Frequently asked questions about tire pressure
- How often should I check my tire pressure?
It is advisable to check the tire pressure at least once every 2 weeks. For long trips or in changing weather conditions you can do this more often.
- What happens if my tires are underinflated?
Underinflated tires increase rolling resistance, which means you use more energy when cycling. This can also reduce the range of your electric bike and increase the chance of flat tires.
- Can I overinflate my tires?
Yes, overinflated tires can make the ride uncomfortable and reduce traction, especially on slippery roads. Always check the maximum recommended pressure on the sidewall of your tire.
- Why is my tire losing pressure?
Tires gradually lose air due to the rubber material and temperature differences. This is normal, but regular checks help to prevent large pressure differences.
- Does the type of valve affect tire pressure?
No, the type of valve does not determine the pressure, but it does determine which pump you need to inflate the tires. Make sure you have a pump that is compatible with your valve.
- Can the tension differ per wheel?
Yes, depending on weight and riding conditions you may choose to use slightly different pressures for the front and rear wheels. The rear wheel often carries more weight and may require higher pressures.
- What is the effect of temperature on tire pressure?
In cold weather, tire pressure can drop, while in warm weather, pressure can increase slightly. Keep this in mind and check your tires regularly in extreme weather conditions.
Conclusion
The correct tire pressure is essential for the comfort, safety and performance of your electric bike. By regularly checking and adjusting the pressure to your riding style, weight and conditions, you will get the most out of your bike.
Paying attention to your tires will not only improve your driving experience, but it will also extend the life of your tires and battery. Make it a habit to check your tire pressure, and enjoy an efficient and comfortable ride, whether you’re commuting daily or taking long bike rides.
