Properly inflated bike tyres are critical to ensure a safe, comfortable and efficient ride. Inflating a bike tyre is a relatively simple process, but it can be confusing for those who are new to cycling or have never done it before. This guide will provide a step-by-step process for pumping up your bike tyre, as well as an overview of the different types of bike tyre valves.
Before you begin, you will need a few tools: a bike pump, a tyre pressure gauge, and a valve adapter (if necessary). A tyre pressure gauge is important to ensure that you are inflating the tyre to the correct pressure, which will be marked on the sidewall of the tyre. A valve adapter may be needed if your pump is not compatible with your valve type.
How to pump up a bike tyre
Step 1: Determine Your Valve Type
There are two main types of bike tyre valves: Schrader and Presta. Schrader valves are similar to those found on car tyres, while Presta valves are thinner and have a threaded top that must be unscrewed before inflating. The valve type can typically be determined by looking at the valve stem, but it is always a good idea to double-check before inflating.
Step 2: Remove the Valve Cap
The valve cap is a small plastic or metal cap that covers the valve to prevent dirt and debris from entering. It is important to remove the valve cap before inflating the tyre.
Step 3: Unscrew the Presta Valve
If you have a Presta valve, you will need to unscrew the threaded top of the valve before inflating. This will allow air to enter the tyre.
Step 4: Attach the Pump to the Valve
The pump should be attached to the valve by pressing it onto the valve stem and then flipping the lever or tightening the screw to secure it in place. If you have a Presta valve, you may need to use a valve adapter to ensure a tight fit.
Step 5: Inflate the Tyre
Begin inflating the tyre by pumping air into the valve. You should continue to pump until the tyre reaches the recommended pressure, which will be marked on the sidewall of the tyre. Use a tyre pressure gauge to check the pressure periodically as you inflate the tyre.
Step 6: Remove the Pump from the Valve
Once the tyre is fully inflated, remove the pump from the valve by releasing the lever or unscrewing the screw. If you have a Presta valve, screw the threaded top back onto the valve.
Step 7: Replace the Valve Cap
Replace the valve cap to protect the valve from dirt and debris.
What are the different types of valves?
Valve Types: Schrader valves, also known as American valves, are the most common valve type and are typically found on mountain bikes, cruisers, and many hybrid and comfort bikes. They are similar to the valves found on car tyres and can be inflated with a standard bike pump.
Presta valves, also known as French valves, are thinner and lighter than Schrader valves and are typically found on road bikes, high-end mountain bikes, and some hybrids. They have a threaded top that must be unscrewed before inflating and can be inflated with a bike pump that has a Presta valve adapter.
Both valve types have their advantages and disadvantages. Schrader valves are generally more durable and less prone to damage from rough handling, but they are also heavier and may require a pump with a larger opening. Presta valves are lighter and easier to inflate to high pressures, making them ideal for road bikes, but they can be more delicate and require a specific pump or adapter.
Inflating a bike tyre is a straightforward process, but it is important to use the correct valve type and inflate the tyre to the correct pressure to ensure a safe ride.
