We designed the BB86/92 Adapter set to allow a68mm Bafang motor to fit a BB86/BB92 bottom bracket(inner diameter 41mm) frame without having to modify or disassemble your motor. This will only work with frame with 41mm inner diameter BB.
Note: This adapter is designed to work with frames with a BB frame tube outer diameter of less than 47mm ideally (48mm will work but motor will space out 2mm). Carbon frames often have a thick layer of carbon and the motor can’t fit. From our experience we have found frames with ISG chain guide mounts may require some modification as these mounts can interfere with motor clearance. Feel free to contact us before purchasing this if you are unsure.
