How to Pump Up the Tires on an Electric Bike
And how to choose the right pressure

How to Find the Recommended Tire Pressure

You can find the recommended range of any standard tire on the tire itself.
In the photo, you can see the recommended tire pressure easily, as it's circled in red. But it's a confusing string of numbers! However, these numbers are easy to interpret, once you know how.
The first numbers here are the recommended pressures in kiloPascals, the second set is in Pounds per square inch (PSI), and the final string is in bars. KiloPascals, PSI and bars are all measures of pressure, and we could use any of them to pump up the tire.
However, this also depends on what units our pump uses!
Our pump here at Powerbikes.com uses PSI, which is common in the United States. As you can see on the example tire, the minimum tire pressure is 50 PSI, and the maximum is 75 PSI.
Why are the minimum and maximum tire pressure important?
The pressure in your tire is important--it's one of the primary determinants of your ride quality.
If your pressure is too low, you're at increased risk for flats.
And if it's too high, you'll be putting unnecessary strain on the tire and tube.
Therefore it's important to remain within the recommended range of pressures on the tire.
Choosing the right tire pressure for YOU
Why you might choose LOW pressure
There are many benefits to running your tires with a lower pressure.
In poor conditions, a lower pressure helps the tire maintain maximum traction, which is important, especially in winter or icy conditions.
Additionally, the lower pressure means a more comfortable ride. With lower pressure in the tire, small bumps in the road are absorbed by the tire, and this effect increases the wider the tire, and the lower the pressure in the tire.
Why you might choose HIGH pressure
There are benefits to running tires at a higher pressure.
One major benefit is a sportier and more responsive ride. Higher pressures make it easier to turn quickly and easily, and make the ride more efficient. This is because there is less "rolling resistance" and less friction with the ground. If you are looking to maximize the range of your battery and are looking for a sporty ride, try pumping your tires up to the higher side of the recommended pressure range.
Additionally, at higher pressure there is a reduced chance of certain types of flat tire.
