Answer 1

Flat Tyre:

Take off wheel (If you are still using bolts to attach the wheel I would invest in a set of quick release skewers.

Take all of the air out of the tyre (Even with punctures there is sometimes a bit left.) Place tyre levers between tyre and rim - push both down and slide one lever around rim to remove tyre. (Two spoons also work for this).

Take out tube, inflate and place in lightly soaped water. Look for bubbles and use repair kit once hole is discovered (Ask for slime for birthday. Will solve a lot of problems).

Partially inflate tube and place in tyre before re-fitting to wheel. Re-inflate and replace wheel (You may need to undo brakes on some bikes.

The chain

This might be tricky as the number of links that you need might be different on your second bike. Also, if one bike has a different number of gears you could have problems.

However, buy a new chain. If chain is old, the wear might damage your sprokets. Take off old chain (Chain tool needed). Count number of links. Use chain tool to set new chain length. I would also conect using a SRAM power link so that you can take the chain off/on again easily. Try this site for chain:

For how to guid:

www.parktools.com

For the seat. There will either be a one or two bolt system that conects your seat to the seatpost. Undo bolts, which will loosen a clamp. Remove old saddle and replace, tightening clamps. Note: the seat angle can usually be altered from here, so check that your saddle is horizontal at this point. Look at the Park Tools site for how to guides if needed.

Answer 2

If the chain doesn't have a joining link you will need a chain breaker to part the chain for removal. Buy your new chain (a SRAM one will come with a powerlink). Remove the old chain, lay it out and use it to gauge the length you need. If using a link remember to allow for it. ie using a chain breaker remove 1 link more than the old chain length. Fit the chain and join it.
When you say a new seat are you replacing just the saddle or the saddle and seat post? If just the saddle you will need a small wrench or an allen key to loosen the seat clamp. Before removing the saddle measure from the nose to the centre of the headset. This will allow you to position the new one in the right place. Fit the saddle and tighten the clamp - go ride.

Answer 3

Well the picture did not work for me and I have not worked on a bike for a long time

Taking the chain off can be a little tricky. You need to take a look at the chain, there should whats known as a split link, it is like a U that is there to keep two links together. You can push that off and then the chain should come apart into two pieces. Putting the new chain on should be the same.

As for the saddle, there is usually a bolt you have to loosen to adjust the seat. Some just have handles that you can unscrew to take the saddle off

Answer 4

If you look closely you will see a catch on the chain to release so you can pull the chain off, how ever if you need to resize the chain to fit the other bike you will nee a chain seperator tool. They should sell them at any good bike store

tools

full set of wrenches
screw driver
channel lock
allen wrench set
hammer

For the tub you need two screw drivers
Pry one screw driver between the tire and weel frame amd put the tire bead up.
take the second screw driver slide it un the hole and keep going around pryting as you go. the first bead will be loose you now can pull the tube out for

Answer 5

Some people have already given you some good answers.

One addition--screwdrivers can work to remove your tire but are not the best tools. You could easily damage the rim or the tire with screwdrivers. They can get the job done if you have no other choice but... If you can, go to the nearest bike shop and they will have things called "tire irons" or "tire levers" they are made from nylon and are much easier on your rims and tire and especially, the new tube you are putting in your tire. And they are cheap to buy. Thinking of cheap to buy. Two places to buy nice parts at not HUGE prices (although they have that too) are Bike Nashbar and Performance Bicycle.

One other note, it is very easy to get parts of the tube stuck between the tire bead and the rim. If it is, when you inflate the tire, it is likely to explode. I've done it many times. So before you inflate the new tube, check to make sure no parts of it are bulging past the tire bead.

Answer 6

Oliver,
I like your honesty this shouldn't be too hard
1. if you know what size of tire you need make a note of it
go to the store and get it. You mentioned you think you can replace the tube, you don't sound sure so get you dad to help you. 2, Your chain sounds like it needs to be replaced. Before you go on the bike make sure your chain is lubricated good. The same for the bearings.
3. The seat those can be bought at any hardware or bike shop store. I think all seats can be removed put on.

Answer 7

to take the chain off you need a chain breaker and no its not a hammer. its a tool that loosens the pins which hold the chain together. you can find it at a local bike shop or http://www.danscomp.com/811087.php?cat=TOOLS

otherwise you need simple stuff wrench, allens keys

Answer 8

i will no longer be able to verify it being a difficulty, till getting great thighs is frowned upon in ballet. Bicycling does wonders for cardivascular wellbeing, improves stability and coordination, and is a great non-effect workout for the legs too. even though it may deliver approximately huge, meaty thighs. i admire my legs that way, so cycling's the sport for me. :-)
