The mukluk looks like a nice fattie--i got a used fatbike a few winters ago and really enjoy winter trail riding. A real hoot and a fun technical challenge with traction and balance, I get a kick out of trying not to have to dab or put a foot down. Plus sliding is always fun and it's all good for keeping bike control skills up. Don't use it really in the summer, snow to me is where it's most fun.
Have fun with new toy when it arrives. A pinion belt drive bike would be a gas, but pretty unlikely in reality, but fun to read about.
There is no snow here, so mine gets used for beach riding and touring where sand is expected and well playing on single track.
