Three Basic Bike Maintenance Tips You Can Do Yourself
If you have read any of my other articles you would know I am pretty adamant about bikes being a utilitarian machine. The reason I say that so much and why I believe is because I believe anyone is capable of maintaining their own bicycles and I am going to give you a few tips and resources to get started.
Co-ops, Tool Libraries, and More
Problem 1 – Flat tire, tube, damaged tire replacement or new tire
Tools you will need: tire levers and a bike pump
Tires and tubes are the most commonly replaced item on your bike because of the material they are made out of and how much they get used. Make sure the wheel is off of your bike before you begin. To remove your tire, first deflate it by unscrewing the top if you have presta valve and pressing down on the valve head itself. If you have a Schrader valve there is a small metal pin inside the valve stem that you should press for the same effect. Once the tube is flat you should the sides of the tire come unstuck from the bead in the rim.
Removing the Tire
If the bead does not come unstuck, position your thumbs parallel up against the tire and your other fingers on the opposite side perpendicular to the tire. Now work the bead of the tire into the center ditch in the rim. With space now in between the tire and the rim use your lever by positioning it under the bead of tire, leveraging it against the rim to pull that first part of the bead outside the rim of the tire.
Tough tires may require two levers working in tandem, one after the other to work that first side of the bead all the way off. Some tires fit looser and you can just slide the lever along the rim pulling the bead over the rim as you go. Once one side of the bead is removed it is time to remove the tube.
Unscrew the valve nut if there is one and push the valve stem up through the rim, then continue by removing the tube from inside the tire puling it out completely. Next, get the other side of tire’s bead out by using the same process on the same side of the rim we removed the bead from the first time.
Once the tire is off you have many different options to choose from. If you are replacing the tire go ahead and get your next tire lined up. If the old tire is still good I would keep it in case you need a quick replacement in the future. If you are keeping the tire, rub your thumbs along the inside surface of the tire looking for punctures or sharp objects that could cause damage to your tube. Once you have determined that tire is in good condition it is time to check the rim for any problems as well.
Checking For Punctures
Run your thumbs along the ditch of the rim check for any sharp objects and any damage done to the rim tape. There often isn’t any problem here but sometimes there is and the rim tape needs to be replaced also. Now take the first bead of your tire and work it up onto the rim. Make sure you pay attention to any directional markings on the tire so your tread faces the right direction. The first side should be easy to be hand using your fingers and thumbs in the same rocking motion I mentioned before.
Once one side of the bead is on, get your new tube and inflate it using the pump just a little to give it a shape. Match up the tire brand and logo with the valve stem and the valve hole. Put the valve stem through the valve hole and work the rest of the tube into the tire. Once it is properly seated, work the remaining tire bead back over the rim using the motion I described before. It will be getting tighter and tighter as you near the end and may be difficult to do with your hands. If you must use a tire lever be extremely careful as not to pinch the new tube between the lever and the rim.
Once the tire is properly seated on the rim and no parts of the tube are stuck between the rim and tire, inflate the tube to the desired pressure. You can find the min and max printed on the side of your tire. Your optimum pressure may be somewhere in that range based on your weight and the type of terrain you are riding.
Problem 2 – Seasonal Drive train Wear
Tools you will need: Bucket of soap and water, mini scrub brush, dry rag, chain lube
It is important to keep your drive train clean and lubed. If you do not take care of your drive train parts can begin to wear out and cause much more damage and cost much more to replace than just doing some regular maintenance.
To begin, fill a bucket with a gallon (2.5 liters) or so of water and a tablespoon of dish soap. I am sure you can use other types of soap but this always works for me. Slosh the mixture around and make sure the soap is evenly dispersed. Put your bike up in a stand or if you don’t have one just lean it up against a wall with the drive train facing out. Dip your brush in the water and begin scrubbing all the parts of the drive train.
This includes the crankset, chain, jockey wheel on your rear derailleur and your cassette or freewheel. It doesn’t have to be sparkling but the cleaner the better. Sometimes I like to turn the cranks and just hold to brush in place over the cassette or chain. This guarantees that each part gets the same amount of cleaning. Once you are satisfied with your drive train take a hose or different bucket of water and rinse it down, getting all of the soapy residue off. All of the water will evaporate and your drive train will be as good as new.
To re-lube the chain pick a spot on the chain and stick the nozzle of the chain lube bottle and hold it. I usually do it right on top of the chain back by the cassette but not over the cassette. I do it there just because it is easy to reach. Now, turn the cranks while applying a steady bead of lube to the chain. Do this for about 3 revolutions. Now take a dry rag and pinch the chain in a place that is safe for you to hold while you turn the cranks. Let the chain slide the rag getting any excess lube off while you turn the cranks. That is all there is to it.
Problem 3 – Worn Brake Pads or Brake Pad Replacements
Tools you will need: Appropriate allen or hex keys, fourth hand tool (not critical)
If your bike has any type of rim brake (caliper, v brake, or cantilever) then this repair is for you. Sometimes pads get worn and you need to replace them or adjust the pull to account for pad wear. Follow these steps to adjust your brakes.
First you want to release the tension of the brake cable. Most brakes will have a way you can release the tension without fully releasing the cable. For caliper brakes there should be a lever you can pull up on the drive side of the brake. For v brakes just remove the noodle from its slot, and for cantilever brakes one end of the cable will have a cable end that you remove from its slot.
Once you have access to your brake pads, begin by removing them using the appropriate hex key. Most pads are tightened into place using a 5mm bolt and additional angling washers. Remove everything but be sure to remember what order the mounting and angling washers went in. With the pads visible check for wear or any major damage. You will see little bits of aluminum embedded in the pads. This is completely normal and helps give the bike more stopping power as the pads wear.
To replace caliper or road pads you would just tighten the new ones into place on that caliper break arm. It is very important that you follow the arrows imprinted on the pad so that the brake pad faces the right way. Sometimes you can just replace the pad and sometimes the whole pad mount needs to go too.

So these are some simple repairs you can do with basic tools. There are other repairs you can do with tools that are relatively cheap. Remember to use the multitude of resources you have both for tools and for new knowledge. The internet has most things you would need to fix your bike. Don’t be discouraged if you can’t do the repair just right, try again and you will get better each time.
