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!


BruinBikeSmart Wins SCAG Sustainability Award!


bruinbikesmart_blogThe UCLA BruinBikeSmart program has won the 2017 Southern California Association of Governments (SCAG) Sustainability Award for active transportation. This award is the region's highest honor for projects that promote and improve mobility, livability, prosperity, and sustainability in Southern California.

UCLA BruinBikeSmart is a safety and education program that allows cyclists who receive a moving violation to have their citation dismissed by completing an online interactive bike safety course and paying an administrative course fee. This program is the first of its kind for LA County, and developing it required an extensive amount of coordination between Transportation, UCPD, and the LA County Superior Court.

A total of seven planning projects were selected this year, and will be honored at an awards luncheon on Thursday, May 4. Other recipients include the cities of Long Beach, Lynwood and San Bernardino, the Imperial County Transportation Commission, Los Angeles County Department of Parks and Recreation, and the Transportation Corridor Agencies.

The Cycling Tech that Just Keeps on Innovating


bikelaneCycling goes hand in hand with technological development and environmentally friendly thinking. While the bike and the cyclist are naturally the beating heart of this relationship, there is one little piece of technology which has helped improve the lives and safety of cyclists the world over while not costing us the earth.

That little something is the humble LED bulb. At the beginning of the 90s it came in and replaced the inefficient easy-to-break incandescent bulb as the bike light to use. Since then it has become more effective and more powerful while using a fraction of the energy to use. While it gets more and more affordable, it is also getting better, and crucially, is flexible enough to be woven into a range of new technologies.

Some of these innovations are directly tied to improving cyclist safety. These include:

  • Safety projections - so cars know you are in their blind spot
  • Light display coats - safer than the headlight and the glow in the dark coat combined
  • Illuminated pathways for cyclists and pedestrians - reducing the need for streetlights on some paths.

These are just some of the ideas being developed. You can learn more about these and more by checking out this article on how LEDs are helping to make cyclists safer.

Bike (Re)cycling Day is Back For its Sixth Straight Year!


blog-2016Bike (Re)cycling Day is back and set for Sunday, Nov. 6 from 10 a.m. to 2 p.m. on the rooftop of Parking Structure 8! As always, you will have the opportunity to receive used bikes or used bike parts for FREE.

For those new to UCLA, Bike (Re)cycling Day is our popular annual event where UCLA Transportation gives abandoned bikes and bike parts (as-is) to members of the UCLA community.

Some of the bikes will be in decent working order, some may need a light tune-up and others are stripped down to their frame. Recycled bike frames offer an excellent opportunity for those interested in building their own bike from the ground up or to replace a broken part on their own bike.

Participation is based on a random lottery being held by UCLA Transportation. The registration process will reduce chaos and tent pitching, while helping to create an equal opportunity at cashing in on a free ride! The lottery closed Monday, Oct. 31 at 9:00 a.m.

Eligibility guidelines:

  • ONLY UCLA students, staff and faculty members with BruinCards may participate. You must display your BruinCard and lottery ticket number to claim a bike.
  • Lottery numbers will be distributed via email on Monday, Oct. 31.
  • Limit ONE bike (or parts that total one bike) per person.
  • Bikes will be offered in ascending order starting promptly at 10 a.m. If you are not present when your number is called you will be passed.

Bike technicians from the UCLA Bike Shop will be on-site to answer your questions regarding your new find.

6 Ways to Share the Road with Cyclists


sharetheroadBecause drivers, cyclists and pedestrians all must share the road, accidents are usually unavoidable. And while there are potential dangers to different methods of transportation, driving, cycling or walking can be done safely. Still, if you are aware and cautious of any potential accidents and harm that may come your way, you can more easily avoid causing or being involved in an accident. Here are six situations in which cycling accidents are most likely to occur and how to avoid them.

  1. Turning Left or Right Onto Another Roadway

When drivers are unaware of advancing cyclists upon making a turn, accidents and injuries are likely to occur. Drivers can turn left and hit the cyclist, or the cyclist may not be able to slow down quickly enough and may wind up slamming into the car. As a driver, you can avoid these types of incidents simply by following proper driving etiquette. Come to a complete stop at each stop sign and look both directions for cyclists—and pedestrians and other vehicles for that matter—before proceeding.

  1. Opening Your Door While Parallel Parking

When you parallel park, be sure to watch out for cyclists approaching from behind before you open your car door. If you don't pay attention and open the door too quickly, the cyclist may not have enough time to react and slow down, causing them to run into your car door. In this case, the cyclist may flip off their bicycle or suffer serious injuries while lying helplessly in the middle of the road. You can avoid this type of accident by always checking your rearview and side mirrors for cyclists and opening the door slowly so that any approaching riders will have time to slow down.

  1. Crosswalks

Cyclists often resort to using pedestrian crosswalks when there is heavy traffic on the road. Be aware that cyclists travel much faster than people on foot, and you may not be able to see them without paying close attention. Always be on the lookout for signs, pavement stripes and riders when you approach a crosswalk to make a turn.

  1. Riding Against Traffic

Sometimes cyclists ride against traffic due to one-way streets. On these type of roads, vehicles travel in the same direction, but cyclists may be riding toward you. Look both ways before turning onto a one-way street, and always watch for oncoming traffic. Simply being more aware of cyclists sharing the road can save all parties from getting into an accident.

  1. Turning Right on Red

When you make a right turn at a red light, there may be a bicyclist in your blind spot also attempting to make a right turn. This maneuver can be dangerous because as you both make the turn, you may steer too close to the bicyclist. Avoid an accident by checking your blind spots and checking for approaching bicyclists before making a right turn.

  1. Simply Not Paying Attention

Accidents can occur simply because drivers do not notice cyclists on the road. Being unaware cyclists share the same road as drivers can lead to a number of accidents that can easily be avoided. To make matters worse, there are a number of cyclists who don't wear recommended reflectors and disregard recommended cycling etiquette.

As a driver with more power on the road than a cyclist, ingrain it into your driving habits to watch out for cyclists and pedestrians. When we are more aware of our surroundings and the people that inhabit the same spaces, we can better share the road and avoid accidents.
