Hi My wife likes the look of fatbikes so I bought a Bafang fatbike kit from california Ebike and have just finished getting it fitted into a new Silverback single scoop fatbike for her. We took it out on the trails on the weekend and I am happy with how it goes. She really likes riding it and now when she asks I can truly say her arse doesn't look fat when riding this! 
Pic of orginal bike below.
As she needed a small frame the battery has to be taken apart to fit on the frame. also some slight reshaping of the rear of the battery case was required. I removed the original Bafang chainring and fitted a 34 tooth Blackspire narrow wide chainring to suit the original x 11 sram X1 gearset. overall weight is 22Kgs.
