BBSHD 68mm to 100mm

[EJ25]

Hello everyone, so I currently have a bbshd on an old hard tail bike it's a 68-73mm motor that I want to swap into a dual suspension bike. I recently purchased a 2012 giant trance X1 for a cheap price so I wasn't really fussed if anything fit because I knew I can sell it for a profit. However I would like to fit the bafang up to it, problem is the bottom bracket is an 89mm pressfit which is much wider than my hardtail BB, is there anyway that I could make that fit? or do I pretty much have to buy a whole new motor that's already 100mm, if that's the case then I'll sell the bike and wait for a older model to pop up. Cheers guys
