Jerome K Jerome's advice on bicycles from 100 years ago or so, still applies to present-day technologies:
There are two ways you can get exercise out of a bicycle: you can "overhaul" it, or you can ride it. On the whole, I am not sure that a man who takes his pleasure overhauling does not have the best of the bargain. He is independent of the weather and the wind; the state of the roads troubles him not. Give him a screw-hammer, a bundle of rags, an oil-can, and something to sit down upon, and he is happy for the day. He has to put up with certain disadvantages, of course; there is no joy without alloy. He himself always looks like a tinker, and his machine always suggests the idea that, having stolen it, he has tried to disguise it; but as he rarely gets beyond the first milestone with it, this, perhaps, does not much matter. The mistake some people make is in thinking they can get both forms of sport out of the same machine. This is impossible; no machine will stand the double strain. You must make up your mind whether you are going to be an "overhauler" or a rider.
