I just bought my first Fattie three weeks ago for $720. It’s a rigid Fuji Wendigo 2.1 with 5” tires. The bike is a beast that I’ve gotten down to 34 lbs with a few simple mods. (
see post here).
It was a complete impulse buy. The first time I saw a fat bike on a trail I actually thought to myself, “That’s just dumb”. Here I am a few years later, riding one - and loving it!
Mind you, mine is a budget buy to get me through winter and a wet spring. So far it’s paid off but come summer I’ll be riding my faster, quicker, lighter and more agile trail bike. To me Fat bikes are a niche market that are almost utilitarian. Not sure dropping a lot of coin on one is a smart investment. Of course, “a lot of coin” is relative. Only you can make that call.
Good luck!
