A bike "has a" engine. So this becomes "has a" relationship.

But, how can we create an obj of a class before even creating it?

But inheritance rule is only derived class can access base, base class can not access derived class.

This method is also called as 'containership' or 'nesting of classes'.

Here class bike inside have created the object of engine class. So we can easy to access data member of engine class.

Here by creating the Engine objEng in the Class Bike will make a access to the Class Engine and also the data member of the Class Engine, Only if it (Class Bike) is having the Member function. And By this we can access the data member of the Class Bike via Class Engine itself.
I think this reason is correct, if anything is wrong please correct me with exact reason.
