Minibike or real bike?

I havent got my cargobike yet it takes some more months before I get any and in the meantime I train on a minibike in my home but I have always wondered if training on a minibike like this one gives you the same excersice as a real bike does?

I also have thought of buying a bike like this to have indoors and train on it when its raining or snowing outside and I cant use my real bike.
