I own a Charge Fatbike and am in love! Like many, I will look to find ways to either make it a bit lighter or buy another... but it's a good value for sure. What line of bikes does your shop carry? There are many major brands now that are carrying Fatbikes as well, so you may have even more options. The truly cool thing about FAtbikes is that you always change wheels and eitherstay 26" or larger/narrower and create a whole new bike... great to change things up a bit.

Have fun deciding what you want; they certainly are a LOT of fun!!
