I searched all Spring for a fat bike in my size (XL) before something reasonably priced popped up. No new ones in sight, people were asking MSRP or more for used ones. The only other option was a whole shed load of Northrock (Costco) 'One Size Fits All' fat bikes, which likely wouldn't work for me or OP.

Through patience and a willingness to drive 2+hrs away at moments notice I did find a good quality one (2017 Norco) for less than a new one would cost, but it took a while.
