HAND PUMP

hand pump is a mechanical device that uses human power to lift or move liquids. They are typically used in situations where there is no electricity or an alternative power source is unavailable. Hand pumps come in a variety of designs and can be used for a variety of purposes

Hand pumps:These are small and portable pumps that can be mounted on a bicycle frame. They are a good option for carrying on a bike ride in case of a flat tire. However, they can be more difficult to use than floor pumps.

Here are some of the features to consider when choosing a hand pump:

• Valve compatibility: Make sure the pump is compatible with the type of valve on your bicycle tires.
• Pressure gauge: A pressure gauge allows you to see how much pressure is in the tire. This is important because over-inflation can damage the tire and tube.
• Barrel size: The barrel size is the length of the pump. A larger barrel will inflate a tire more quickly, but it will also be more difficult to carry.
• Hose length: The hose length should be long enough to reach the valve on your tire.
