93mm is a wide bottom bracket shell width that is commonly found on newer press fit BB92 mountain bikes.
The Bafang kit I am selling is the 100mm version. It will work on bottom brackets 68mm to 100mm wide. I have 2 different non drive side crank arms that come with the kit. One is straight and one angles out. One is for running the kit on 68 to 73mm bottom brackets and the other is for running 74 to 100mm bottom brackets.
