what is a bicycle? what is its uses?

See my pic...Jesus used it when his donkey was having a day off !!!

It is opposite the direction the bicycle is moving

A good site is Weight Weenies.  Shows the weight of many bicycle parts.

you use your hands to pedal...it has different gearings on the cogs, freewheel, and sprocket. it is a funny position to ride in but is very good to strenghthen your arms and your whole upper body. it just takes getting used to.

First thin is what kind of bicycle you want or like? road , mountain, speed, bmx, etc. Then check your budget. Even though if you have plenty of money, you have to start with a nice but not expensive bike. Why? you have to adapt firt. What about that after you buy an expensive bike, you do not like it( that's an ex. ) Then after a while if you know taht this is what you wanted or you are very good at it sell it and buy a very good bike. Remember to buy a helmet too.

What bike... What are you talking about????

Quite simple.\nYou pedal the cycle to rotate a gear . The gear is connected to a chain which rotates another gear connected to the wheel and when this wheel rotates, it pushes you forward.\nAs for the balance, it depends upon the rider.

The wheel rotates while the axle connects two or more wheels together and provides a means for the wheel to be used for motion (as in a vehicle).

I am an "ordinary cyclist", maybe even less than "ordinary" and it works for me.  I use a rim drive trainer with a mountain bike.  Extremely boring though.

A bicycle seems like a good base. If you connect it to a automotive alternator and 12v battery you can produce and store power using cheap available items.\n\nIf you want 220 volts, you can buy inverters that produce it from a 12v battery, again using "off the shelf" equipment.\n\nHappy cycling cause I think you are going to find the human body quite limited at power production.\n\nps, To build something using the items I suggest would mean supporting the bicycle, hopefully you could use the wheel as a pulley without its tire and drive the alternator (having the gears of a standard bicycle being better than an exercise bike to try and match the ratio you need) Since we're not talking much power, the drive belt wouldn't need to be too technical but you may want to change the pulley on the alternator to something wider to match the wheel. If your bicycle support is bolted to a piece of plywood laying on the floor, you should be able to bracket the alternator to that plywood and keep the belt tight enough.\n\nThe electrical connection is fairly simple, connect the big lug on the alternator to the car battery +ive and the casing to the -ive. You will need to connect a small indication light between the small lug and the +ive as this is part of the charge circuit. I suggest a ammeter in the circuit to prove the doubting people on here they are wrong and that you can drive a charge current into the battery but don't buy one with too big of a range :-)\n\npps Try to select a low power alternator (off a small car). \n\nppps If you want to do this without incurring a large expense, you need to make best use of parts that are readily available and do the engineering to suit. If this is not your best subject, you may need to seriously consider whether you want to waste any time any money attempting it.

look up the question on here "why do bicycles gain stability as the speed increases?" then do a report on that, its original fun and fantastically interresting

All I can think of...\nGravity (weight of bike + person), friction (of ground and all axles), pedal force (not constant because you are pushing on an arc), air resistance, inertia (this is why it gets easier to pedal once you get to constant speed), sprocket ratio, gyroscope effect (makes it easier to balance).

Go get on your bike, and try to do some tricks.  This is a stupid question.

By law, if you're riding a bike on the roadways of America, a bike is considered a vehicle and are subject to same laws as if you were driving a car. Check it out.

Balancing on a bicycle is mostly the act of correcting the wobble.  As you start to tip right, you angle the wheel to the right a tiny bit and roll the bike back underneath yourself.  The actions are automatic and subtle, but in order for this mode of balancing to work, the bicycle has to be moving, otherwise turning the wheel doesn't do anything.\n\nThe other balancing, moving your body back over the bicycle, is more difficult, and less important, so most people never get to practise it during their normal use of a bicycle.\n\nGyroscopic effects are unimportant, even moving very, very slowly on a bicycle with very light wheels is much easier to balance than being stopped on the same bicycle.

bicycling. Especially mountain biking. It is fun, challenging and a great workout.
