Hello, I'm trying to install an engine kit on my Mongoose Excursion 27.5". This bike is 21 speed, and has this assembly on the back of the bike.

In order for this engine kit to work, it needs to have one large gear on the pedals, and the shifter on the back wheel needs to go. I was wondering, is it even possible to remove all of these components and still have a working bike?
