Unknown engine, does anyone with good nose have clues?

My next project will be to transform a total carbon that is already mine.Specialized Enduro 29 Expert Carbon 29 !!
As a line of idea is to maintain lightness and evaluating all the possibilities, the most interesting is certainly this.

7,66 kg :shock: !!!

the space between the pedals is perfect could accommodate both motor and battery

My problem is figuring out what kind of engine designer Partin Platter has incorporated.

Analyzing it on sight it looks like a BRUSHED! But it is not possible because in the third photo the engine pinion has no free wheel.
Nor does the crown of the bike cranks have no freewheel. see

Brushed has too much resistance.
But also brushless outrunners.
So I thought INRUNNER! They are very free without resistance. Inrunner 2 poles are free to spin indefinitely little little resistance. But many many KV !
Any idea? Do you see something that escapes me? :!:

a thousand thanks

Many greetings Amberwolf , I have read everything, I too have thought of an engine with planetary reduction. But it is not: it is not possible if you remove the pinion protection, the motor would be too short.
Theoretically how low Kv could an inrunner be? :?:

there are examples of motors for surf foil, without gearbox at low kv but expensive! and difficult to cool in air better underwater
