The cheapest available BMW i3 listed for sale is around $14k. The cheapest available BMW S1000RR motorcycle listed for sale is around $8k. For $22k + ???, how difficult would it be to remove the electrical components from the car and replace with the bike engine?

It would net a car that is < 2,500 lbs, RWD, with 200 HP, a 13k redline, and 6 speed sequential manual transmission.

Why has nobody tried this yet? What is the hold up from doing so?
