Well, maybe I want to get this.
On days when I'm tired, it's raining, or the ground's icy, I would want to have this. This all-in-one wheel conversion to make an electric bike. It would make it easy to convert from my comfortable middle-distance touring-esque bike (that can average 20+ mph on the flats) to an around-town runabout (with a 20mph limiter).
What I like about it is the modularity.
... and the music.
