i did see a 68 x 142, on ebay.... it might be made to kinda fit.... ?
ebay search: Bike Bicycle Bottom Bracket 68 x 142mm Square Taper

and there is an Origin8 that's not too spendy... it might work with spacers and a lock ring... ? you'd lose a half inch of shell contact, per side...
ebay search: ORIGIN8 XLT Square Taper BB 100mm x 164mm English JIS Steel Bottom Bracket

or go to a box store that stocks several fat tire bikes, measure a few BBs, and contact THAT MFG for a spare part....

Thanks, we will follow up with your suggestions

pic of manuf, Bike was built 2014-2016 by DK MTB and is the "Duke" model. We have attempted to contact the manufacturer this morning. We did look at the parks on the web site but it is not listed.
