We just got in a new Fatbike from Mongoose. The Malus $349.99 retail. 1x8, with grip shift. Not a bad bike at all. (We have 3 on the floor right now) They are the upgrade to the Dolomite bike, but with ALUM frame, better rear D, and shifter.
The Mongoose Vinson's sale price for the month of March is $549.99 We have on on the sales floor right now. I hope to get another one or two in a few weeks.
