How do you fill the tires on this bike. The valve stems are not typical bike tire stems. I am (obviously) a novice biker and have not owned a bike in several years. The pump I bought is a Schwinn pump (I would assume it is meant for the bike) and has two attachments a yellow one with one wider end and one narrow end and a traditional "football/basketball" silver attachment. Which do I use and how

The adapter for car tires should work on the bike tires. If you are using a compressor with a regulator and gauges then with a full tank of air adjust the regulator so the output gauge is set to the pressure you want the bike tire be be. This makes it take longer to fill the tire but reduces the changes the tire is overfilled and damaged. If you have an old fashioned bike pump and want some exercise that is different than biking then that works also. The valve stems on the bike tires have threads just like the car valve stems and the valves and caps are interchangeable.

This pump is a bit strange to use. The valve in the filler head is odd in that it controls the flow of air in both direction...which is not a great design in my opinion...but it does allow for use in different filling applications. The trick is getting the pump into its different filling "modes"

For a Schrader bike valve:
1. Make sure the pump is in "tire mode" by blowing into the valve with your mouth. If you then pump the handle you should feel air filling your mouth.
2. Put the "locking lever" in the unlocked position, the unlocked position is when the silver metal lever is parallel to the air hose, or said another way it makes an "L" with the air outlet that goes on the tire air filling stem. To verify this is correct, look in the air outlet and move the lever from locked to un-locked, you will see slight change in the diameter of the outlet.
3. Push the air filler hole over the schrader valve really hard and make sure it is seated all the way down. Close the "locking lever" (silver metal lever should now be perpendicular to the air house and be in line with the air outlet... i.e. point straight out away from the tire filler stem.
4. Pump.

For a Presta bike valve:
1. Make sure the pump is in "tire mode" again.
2. Take off plastic caps off presta valves on bike tire.
3. Unscrew the little nut on the presta stem to allow the tire valve to open when pressure is applied (you can test this by pushing the stem in a little and air should escape, the nut holds the valve closed, so it needs to be loosened).
4. Take the adapter from the locking lever (silver metal lever) on the pump and screw it on the presta valve. The adapter is the brass looking thing. Screw the rubber gasketed side down on the presta valve.
5. Press the air pump tire filler outlet onto the adapter.
6. Close the locking lever to seal the filler head on the adapter.
7. Pump.
8. Unlock the locking lever and pull it off quickly.
9. Unscrew the presta adapter and screw down the presta valve nut but just finger tight.
10. Screw on the plastic cover cap for the presta valve.

To Fill a Ball:
1. Twist the ball pin filler out by rotating the gray plastic tab around until the ball pin filler is pointing straight out (in-line with the air hose).
2. Make sure the pump is in "Ball mode" by again blowing into the filler. Sometimes shaking the filler valve really hard is necessary.
3. Put the filler pin into a ball.
4. Pump.

Hope this helps.

also most bike stores will probably help you out for free

Valve stems typically cost anywhere from $.59 to $2.00 to $3.00 a piece depending on where you go.

Sears would probably charge about $2 or $3 for a valve stem in one tire.

Your bike tube has Presta style valves. Automotive style valves are known a schraders. To inflate the tube, you will need either an adapter, presta to schrader or a hand pump that has a head for presta valves. Any bike shop will have one for sale. To fill the presta valve style, remove the black cap(if it is there) You will see little stem with a small knurled nut. Screw the nut all the way up until it stops. Put the pump head over the stem, making sure it is pushed down. Flip up the lever on the pump head, fill to desired pressure 100 to 120psi...yes, that much pressure, it's a road bike. Flip the lever on the pump head down and remove it from the stem. The PSST you will hear is the air from the line on the pump...not the tire. Screws the knurled nut down and replace the black cap. If you do not srew the little nut down and push on the stem you will let the air out of the tire. If you need more help, you can email me @ [email protected] and I will send you pictures of the process, or the staff at your local bike shop should be able to show you how.

Replace the valve stem or have it replaced. There is a special tool to unscrew the valve stem. Remove the wheel and tire from the car and depress the pin in the stem to release the air in the tire. When you have about 90% of the air out of the tire, insert the tool into the stem an turn counterclockwise to remove. After you install the new valve stem, get a ride to a gas station that offers free air and fill the tire up. As long as the tire is still seated to the lip of the rim (check just for your safety but I very highly doubt it unseated from the rim) and fill the tire to the cold psi rating which is stamped on the sidewall of the tire. If you want to check the tire itself for a slow leak prior to doing the steps above, here is what to do. Get a pan or plastic tub that is sightly wider and longer than the tire and rim. Fill the tub with water and set them it in the water (while it is still filled with air) and slowly roll the tire in place and look for small air bubbles to rise. If you see bubbles, there is a leak.

Why? it should work unless the valve on the tyre is faulty than you need an inner tube for it. You can order inner tubes from www.buggypitstop.co.uk

the tire industry recommends 32-34 PSI in all 4 tires

The first step is to remove the wheel assembly from the bike. Once that is done insure all the air is removed from the tube by holding in the needle on the valve stem. You may have to remove the cap from your valve stem first. Next, using a flat blunt tool, pry the inside lip of the tire away from the rim and hold down the tool. Make sure you don't have the tube pinched with your tool. Next, using a second tool, repeat the first step about 6" from the first tool. This should start the tire to come off the rim on the side you are working on. You should now be able to pull out the tube and inspect for holes. Use a simple tire patch kit if you can or simply replace the tube.

To replace the tube, remove the valve stem cap and insert it from the tire side through the hole in the rim for access. Replace cap on stem to help hold valve in place. Carefully lay tube inside tire without folding it. You may have to bunch it up a bit. Start pushing tire edge back around the edge of the rim. When you get almost to the end it will get tough to if the tire is tight.Use your blunt tool to help it over the edge of the rim. Once the tire is on, make sure the valve stem is pulled up tight and straight before refilling with air. Inspect the tire to make sure it is seated on the rim all the way around on both sides. If not, release air from tube and make adjustments and refill. Replace wheel on bike and enjoy your day!
