Tranny not fitting

72t oh wow I have a 54t right now but haven't been able to ride still in process of building. As for my tranny I got it from bikeberry.com they have what to me was an upgrade tranny because not only was it bigger its geared to something like 6:1
This piece of $100 junk?
Does not say Hoot or 4G or anything about 6 to 1 ratio.
Count the teeth on the 2 internal gears which will be about 3 to 1.

Yes that link you put in your reply is the tranny I purchased. My apologies if the name of tranny I used was incorrect but I'd heard them called that more than a few times & I still very new to motored biking as my current build is my first. There are dual chains internally with 41teeth gears and the outside driving gear has 11 for tranny. There was something said about another internal gear that drove the drive gear that had something like 6 teeth also. Which comes down to about 6:1 ratio
