How to Change Your Bike’s Tire

He always gets the job done in time

He always gets the job done in timeFlat tires on your bike are always a frustrating thing to have to deal with. However, all of this can be avoided if you're adequately prepared. So grab your tools and follow these simple directions to get back on that road in no time.

Before we begin, make sure you have all the necessary tools: a spare tube, a pump, tire levers, spare tube, wedges, and rim tape.

Remove The Wheel

  1. We’ll begin by loosening the nuts that hold the axle to the frame. Use lubricant if you run into problems while trying to loosen them.
  2. Remove the wheel from the frame. If it's the rear tire, you will need to lift the chain clear of the gear cluster. For better instructions on how to do this, watch the video above for a step by step run down.
  3. Deflate the tube completely by pressing down on the small plunger located in the center of your tire/inner part of the valve.
  4. To remove the tire, use tire levers, or a similar object. With the first lever, pry the tire over the rim. Repeat process four inches away with a second lever, move lever around the rim to release the tire.
  5. Remove the wheel and tube completely - you may need to unscrew a small nut at the base of the valve stem to take out the inner tube.

Inspect, Repair, or Replace

  1. Make sure inspect the punctured tube thoroughly - check the outer surface of the tire for any signs or foreign objects (cuts, tears, etc.) that may have punctured your tire (make sure to also check the inner surface of the tire for similar damage).
  2. Wash up and dry up the damaged area (rubbing down the damaged surface with sandpaper will help the glue adhesive stick).
  3. Adjust patch and place over adhesive after removing all sharp/foreign objects from inside the tire casing. Replace the inner tube or tube and tire if damage is severe
  4. Before replacing, make sure to purchase the right tube and tire size. Measurements can be found on the old tire.

Replace Your Wheel

  1. We’ll begin by checking the tire wall for an arrow or similar symbol to indicate the direction of rotation - some tires have a "direction specific" tread pattern.
  2. Put one side in first, then ease the partially inflated tube into the tire and locate the valve. Make sure no part of the tube is sticking out.
  3. Starting at the tire edge closest to the valve, use your thumbs to work the other side of tire over the rim and into the well. You may need to use the levers to do the last bit and pop it back into the rim.
  4. Use your thumbs to ease the tire from the rim around the entire wheel, make sure the tire is not pinching any part of the tube. When you inflate the tube, if it's pinching, it will pop and you will have to start over.
  5. Inflate the tube slowly and carefully, while checking to make sure the tire is on evenly and nothing is "pinching."
  6. You’ve done it! Enjoy your ride!


The ABC’s of Bike Safety

Cycling and Sport Concepts: Handsome Caucasian Rider Having a Bi

Cycling and Sport Concepts: Handsome Caucasian Rider Having a Bi

UCLA's Bike Week festivities may have come to an end, but National Bike Month is still in full swing. As an academic institution, we’re all about instilling the ABCs, and this is the perfect occasion for a refresher course on the nuts and bolts of bike safety. Whether you’re fresh off the training wheels or a long-distance cyclist, it never hurts to study up.

A is for air. Check the tire pressure. Use a pressure gauge to insure proper pressure. In a pinch a quick squeeze with your fingers can work. Tires should be inflated to the rated pressure noted on the sidewall (pounds/square inch). Spin the wheels and check for any cuts or damage too.

B is for brakes. Take a look at the hand brakes by lifting the bike up, img_Bikesafe_homepagespinning one wheel and squeezing the brake level to make sure the tire stops. Check the coaster, or back pedal brakes, by spinning the back wheel and applying the brake. Brake pads need to be clean, straight and make proper contact with the rims.

C is for cranks, chain and cassette. Grab the crank arms, the part of the bike on which the pedals are attached, and wiggle side to side. There should be no movement. Make sure the chain isn’t dry, rusty or excessively greasy or dirty. The chain should be straight and the crank and pedals tight and secure.

Quick Release: Quick-release hubs need to be tight, but not too tight; quick-release brakes, which are opened when removing or installing wheels, need to be in the closed position and quick-release seat clamps need to be in the right position. And, make sure your seat is the correct height.

Check: Take a slow brief ride to check that your bike is working properly.

Inspecting your bike for mechanical safety is something that should be done before every ride.

Here are some additional guidelines for safely sharing the road: obey all traffic regulations, ride in a straight line and avoid weaving, never ride against traffic and remember pedestrians have the right of way on walkways. Beware the “right hook” by waiting in the designated right turn lane and watching for vehicles also turning and heading into the intersection and avoid the “door zone” by staying 3 to 4 feet away from parked cars. Always pay attention to your surroundings and remember to use hand signals and make eye contact with others.

Happy riding!

Melvin: ‘Thank You For Having the Earn-A-Bike Program’

I work from 5:30 p.m. to 2 a.m. at the UCLA Immunogenetics laboratory. Since there were no convenient public buses to catch for the ride home, I would drive my car to work. However, with the Earn-A-Bike Program, that has all changed.

The TREK HYBRID bicycle is a nice bike.  Weight-wise, it is a light bike. I had no problem lifting the bike ontoBike and KOBE the dog. the bus bike carrier on those days when not commuting round trip. It is a solid bike for those times in traffic when you must take the street pot hole. Of course, you do your best to avoid them; otherwise, you will damage your wheel.

What can I say about riding home at 2 a.m.? It is more fun than bicycling to work in the afternoon. You still have to be careful since there are still cars on the road at 2 in the morning.

Thank you for having the Earn-A-Bike program.
