Alignment and tension are the most important things to adjust. Check you derailleurs and spring tension devise. Clean the gears and lubricate them, look for rusted areas of your chain. Assure that your cable connections and hand adjusters are also adjusted correctly and free of encumbrance.
Depends on what's wrong with them and what kind they are. www.sheldonbrown.com, www.bicycletutor.com and www.parktool.com all have info on how to fix your bike.
It depends on the bike if the engine of bike is heavy it has more gears. Usually 5 gears are max gears.
There are seldom only 2 gears on a bike. Many have 12, 18 or 21 .
an average bicycle has up to 24 gears but a bicycle has up to 30 gears
depends on the model. from 2-7 gears
MotoGP bikes have 6 gears.
how do you fix the bike in my sims agents
Depending on the bike yes most adult sized bikes have gears
if you don't keep your chain and gears on your bike greased it will rust and come off.
A good bike today is most likely to have 11 gears(MTB) or 22 gears(road).
a track bike, or a bike with internal hub gears.
To change gears on the bike, all you have to do (while riding it) is press the B button. You don't have to hold it in, either. ~Lucario
Depending on the mountain bike that you have will depict the amount of gears. Most bikes for adults typically have about 21 gears. If this does no answer your question then what are levels?
Unfortunately, you can't change gears on bikes in HeartGold.
big and small

Changing Gears Flagstaff and the Mountain Bike - 2011 was released on: USA: September 2011
That'd depend on what you think of as a standard bike. I'd say that the majority of bikes sold today have several gears, but in my interpretation of a "standard" bike it'd be one with only one gear. Those having gears are most often 10 speeds.
Depends on why it's jumping. It might jump because chain and sprockets are too worn, it might jump because chain tension is too low, or if its a bike with external gears it might jump because the gears aren't adjusted properly. Have a look at www.parktool.com, www.sheldonbrown.com or www.biketutor.com and read more.
I think you mean bike gears, because a faster speed means a better time (the shorter it will take you to get to wherever you are going).That's just common sense.With bike gears though:Higher gears are tougher to petal but allow you to put more push into each stroke.Lower gears are easier to petal but you will petal a lot more often per rotation of the bike wheels.Example: If on high gears it takes you 5 pushes to get to your destination, it will take you 15 pushes with low gears.
Take it to Halfords they fix every bike they can because there's nothing else i can think of
Depends more on what type of gears that you have than it does on the size of the wheels. If the gear levers are the same type as on a bigger bike the 24 inch bike will shift just the same way.
there is no acro bike on Pokemon platinum, you press B to change gears
