Sarah wants to fix a flat wheel on her bicycle. What tool will he use?
Sarah will use a tire lever or an adjustable wrench to fix a flat wheel on her bicycle.
To fix a flat wheel on a bicycle, Sarah will need the following tools:
1. Tire levers: These small plastic or metal tools are used to remove the tire from the wheel rim. They help in prying the tire off the rim without damaging the tube.
2. Patch kit or spare tube: If the flat tire was caused by a puncture, Sarah will need either a patch kit or a spare tube. A patch kit typically includes adhesive patches that can be applied to the punctured area of the inner tube, while a spare tube can be used to replace the entire tube.
3. Pump: A bicycle pump is necessary to inflate the repaired or replaced inner tube. It can either be a hand pump or a floor pump, depending on what Sarah has available.
4. Wrench or Allen key: A wrench or an Allen key is needed to remove the wheel from the bicycle frame. This tool will vary depending on the type of wheel axle and fasteners being used.
5. Optional: It can be helpful to have a bucket of water or soapy water to locate the source of the puncture by submerging the tube and looking for bubbles.
With these tools, Sarah will be able to fix the flat wheel on her bicycle.
To fix a flat wheel on a bicycle, Sarah will need a few tools, including a tire lever and a bike pump.
First, she will need to use a tire lever to remove the tire from the rim. The tire lever helps to lift the tire bead over the edge of the rim, making it easier to take the tire off. Sarah should place the curved end of the lever under the edge of the tire, then pry it upwards to detach the bead from the rim. She will need to do this on both sides of the tire until it can be pulled off the rim completely.
After removing the tire, Sarah will need to locate the puncture in the inner tube. She can do this by inflating the tube slightly and listening for any hissing sounds or feeling for air escaping. She can also submerge the tube in water and look for bubbles to identify the puncture.
Once she identifies the puncture, she will need to patch it. Sarah can use a bicycle patch kit which typically includes rubber patches, sandpaper, and adhesive. She should use the sandpaper to gently roughen the area around the puncture, then apply a thin layer of adhesive. After the adhesive becomes tacky, she can stick the rubber patch onto the puncture and press it firmly. Let it set for a few minutes to ensure a secure bond.
With the puncture patched, Sarah will need to reassemble the tire. She should start by inserting the valve stem through the valve hole in the rim, then evenly work the tire bead back onto the rim starting from the opposite side of the valve stem. Using her hands, Sarah can push the tire bead back onto the rim. If needed, she can also use the tire lever to assist in getting the last part of the tire back onto the rim.
Finally, Sarah should inflate the tire using a bike pump. There are various types of pumps, so she should use the appropriate pump based on the valve type of the inner tube (such as a Presta or Schrader valve). She should attach the pump head securely to the valve, and then pump air into the tire until it reaches the recommended pressure level, which is typically indicated on the sidewall of the tire.
By following these steps and using the necessary tools (such as a tire lever and a bike pump), Sarah will be able to fix the flat wheel on her bicycle.
