Becuase it does not have a reverse gear; reverse gear in a gearbox requires more cogs and drives so it makes the gear box alot more heavier than it needs to be. A bike is meant to be moveable by 'hands & feet'. In the early days (and in some military applications) some combinations (motorcycle & side car) did have a reverse gear; the old German BMW combo also had a drive shaft to the third wheel under the side car.

What is the motion of charges when ac is flowing through a conductor?
Remember, electrons can move very fast indeed, even up to the speed of light which is 300,000,000 (300 million) meters in a second. So, in a wire that is conducting AC (alternating current) the electrons move in just the same way as they do for DC (direct current) except they go back and forth at the frequency of the alternating current. If it is the normal power main's frequency that will be either 50 cycles per second (as in Europe and elsewhere) or 60 cycles per second (as in USA, Canada, etc.). If the alternating current is sound waves going to loudspeakers or headphones the frequency could be as low as 10 cyles per second or higher than 20,000 cycles per second - or even lower or higher than those frequencies but you may not be able to hear them!
