Yes that is a way to do it but that means, lifting it off of the floor, which means getting the stand out which is stowed away in my very small garage so I tend not to bother too much as its only a chain..Just turn the rear wheel backwards, does the same as back pedalling.

I know whats been said earlier but it only runs on the plastic jockey wheels and it doesnt seem to harm either them of the cassett/chainring.
