you need a special wheel that has a "coaster brake"
Fixie bike are bikes (usually road bike frames) that have a fixed rear sprocket which allows you to pedal forward like normal, but does not allow you to just coast . If you pedal backwards it goes backwards if you pedal slow it will remain slow. The whole point of a fixie is to eliminate brakes shifters to simplify a road bike.
The friction is useful on a bike when you push it.
To revert or ride backwards you need to pedal backwards with the chain and the speed of the wheel and then when you get to the right time you can twist around either doing a bronco or fakie or a wheelie around commonly known as a half cab.
A rachet is use in a mechanism that can turn or rotate in one direction, but not in the other direction. Similar to being able to pedal forward on a bike, but not backwards.
You can either pedal backwards while riding fakie, or buy a freecoaster hub which doesn't require any sort of pedaling while you ride fakie.
If the cycle has a fixed wheel with no release ratchet then it will go in reverse when you pedal backwards.
No there is not
Yes you can. It has 25x9 gearing. That means it has a cassette in the rear wheel. Eastern cassette's click very loud if you are into that sort of thing.
PEDAL
Your muscles.
most bmx bikes dont have front brakes now ans if you pedal backward and it has pedal brakes its not a bmx bike
you can use pedal in a sentance like this the pedal on my bike is blue and many other colors
