Step 1: Count the number of gears at the base of the pedals.
If you want to learn how to shift gears on your bike, you'll need a bike that has gears in the first place.
Luckily, this is easy to check.
Start by looking at the pedals.
In the center of the pedals, there should be one or more metal rings with teeth on the outside that fit into the chain.
These are the the front gears.
Count how many gears you see.Most bikes will have between one and three front gears. -
Step 2: Count the number of gears on the rear wheel.
Now, look at the back wheel.
You should see the chain run from the front gears over a different set of rings at the center of the wheel.
These are the rear gears.Count how many you see.
If your bike has gears, there will usually be more rear gears than front gears.
Some bikes have ten or more. , Now, just multiply the number of front gears by the number of rear gears.
This tells you the total number of gears your bike has.Some people also call this the number of "speeds." For example, if you have three gears in the front and six gears in the back, your bike has 3 × 6 = 18 gears (or "speeds").
If you have one gear in the front and seven gears in the back, your bike has 1 × 7 = 7 gears.
If your bike only has one gear in the front and one in the rear, it has 1 × 1 = 1 gear.
This sort of bike is called a "fixed-gear" or "fixie." Unfortunately, you can't shift gears on fixed-gear bikes. , Bikes with gears almost always have hand controls on the handlebars to use for shifting.
When you use the left hand controls, a metal loop called a derailleur ("de-railer") shifts the chain from side to side to make it catch on a new front gear.
There are a few different mechanisms for shifting that are common on bikes.
These include:
Grip shifters that you work by turning your wrist Small levers above or below the handlebars that you work with your thumbs Larger levers next to the handbrakes that you work with your finger tips More rarely, electronic shifters or levers mounted on the frame of the bike , The rear gears have their own derailleur.
Using the right hand controls will move the rear derailleur side to side, making the chain catch on a new rear gear.
The rear gears almost always use the same mechanism as the front gears.
If you can't keep your hand controls straight while you're riding, remember: "right = rear."
You can change your gears to make riding your bike easier in certain situations.
For example, shifting into a "lower" gear lets you pedal quicker and easier, but each pedal won't push you as far.
There are two ways to do shift down:
Shift into a smaller gear in the front.
Shift into a bigger gear in the back. , The opposite of shifting down is shifting up into a "higher" gear.
These gears make it harder to pedal, but each pedal will push you further and make you go faster.
There are also two ways to shift up:
Shift into a bigger gear in the front.
Shift into a smaller gear in the back. , A good way to get the hang of shifting is to simply start doing it! Go someplace safe and flat (like a park) and start pedaling forward.
Try using one of the hand controls to shift up or down.
You should hear the chain click or rattle and you'll feel your pedals get either easier or harder to push depending on whether you shifted down or up.
Try using both sets of controls to shift in both directions until you get the hang of them. , If you're used to a bike that needed you to pedal backwards to brake, this can take some time getting used to.
The chain can only catch on new gears if it is stretched tight, which requires you to pedal forward.
If you shift while you're pedaling backwards or not pedaling at all, the chain won't be tight enough to catch.
When you start pedaling again, it may rattle around or slip off of the gear.
This isn't something you'll want to happen while riding. , The first few pedals you take on your bike are often some of the hardest because you need to go from standing still to cruising speed.
Whenever you start riding, shift down to a fairly low gear to make it quicker and easier to get back up to speed.
You'll also want to do this whenever you come to a complete stop and start pedaling again (like at a red light).
If you know you're going to stop riding soon, it's a good idea to shift into a low gear so you can get started easier next time.
This is especially true if you know you'll have to get out of a tricky spot — like if your home's driveway goes uphill. , As you get going faster and faster, you'll find that the lower gears start to feel "too easy" after a while.
If you want to keep building up speed, shift up.
You'll notice the pedals feel more difficult to push and you'll keep accelerating.
If you're riding around on moderate terrain (like city streets with a few minor hills), a "middle" gear will usually work well for your default cruising speed.
For example, if you're on an 18-speed (three gears in front, six in the rear), using the second gear in the front and the third in the rear should give you a good "middle of the road" option. , This is an important skill to learn — without it, you'll be stuck walking your bike up larger hills.
It's almost impossible to get up a hill in high gear.
However, lower gears let you pump your way up the hill slowly and steadily without too much extra effort.You may find it difficult to slowly climb hills in a low gear at first.
Since you're moving at a low speed, it's a little more difficult to keep balanced than normal.
However, moving slowly means it's easy to drop a foot to the ground if you lose your balance. , If you're trying to build up as much speed as possible, using higher gears on this type of terrain is the way to go.
Gradually shifting to your highest gears will allow you to keep accelerating at a steady rate until you reach your top speed.
Be sure to ride especially carefully when you're going this fast — it's easier to hurt yourself.
Being in a high gear is one of the only ways to be able to speed up while you're going downhill.
Lower gears won't turn the chain quick enough to keep up with the wheels when you're rolling downhill, making it basically impossible to speed up except from the hill itself. , It can feel satisfying to "pump" your bike into motion in a high gear, but it may be bad for your body in the long run.
Straining hard to push a bike that's in too high of gear can put stress on your joints (especially your knees), leading to soreness and even joint problems over time.
It's also not as good of exercise for your heart and lungs as pedaling in a lower gear at a steadier pace.To be clear, you can use your bike's higher gears, but you should only shift into them gradually after you've already built up speed. , As you shift your gears, if you look down at the chain, you may notice that it sometimes points in a slightly diagonal direction.
This isn't a problem unless you pick gears that make the chain run at extreme diagonal angles.
This can make the chain wear down and break over time and can cause rattling and slippage in the short term.
In general, you'll want to avoid having the chain on either the biggest or smallest gears in both the front and in the rear.
In other words:
Don't use the largest front gear with the larger rear gears.
Don't use the smallest front gear with the smaller rear gears. -
Step 3: Multiply the two numbers to find how many gears your bike has.
-
Step 4: Use your left hand to shift the front gears.
-
Step 5: Use your right hand to shift the rear gears.
-
Step 6: Gear down to make your pedaling easier but less powerful.
-
Step 7: Gear up to make your pedaling harder but more powerful.
-
Step 8: Practice shifting up and down in a flat area.
-
Step 9: Only shift while you're pedaling forward.
-
Step 10: Pick a low gear when you start off.
-
Step 11: Gradually gear up as you build up speed.
-
Step 12: Shift down for hills.
-
Step 13: Shift up when on fairly level ground and for downhill areas.
-
Step 14: Shift up carefully to avoid hurting your joints.
-
Step 15: Avoid choosing gears that "crisscross" the chain.
