Depends on what you mean. If you're skilled enough you can get on backwards on just about any bike, and ride it facing the wrong way.
If you've got what's called a fixie(a bike where the pedals always move then the rear wheel moves) then it can be ridden backwards.
If you've got a bike with a freecoaster rear hub you can roll backwards down a ramp or something like that.
Yes, most notibly the Honda Goldwing GL1500 and GL1800 have a reverse gear. The reverse feature utilizes the starter motor and is engaged by pulling up the reverse lever and hitting the starter button. Reverse is slow but allows you esentially back the heavy bikes out of tight spots such as parking lots and garages or if you need to back the bike up an incline.
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.

you need a special wheel that has a "coaster brake"
the difference is that one goes on a bike and the other goes on a dirt bike, the second reason is that one is smaller than the other one to
Of course.
