Buy something really odd all your mates rip the piss relentlessly !! Realise after riding you’ve made a huge error but your loathe to admit it so ride solo taking pics to prove your actually riding it ..
Kind of true I guess 🙂 I mostly ride on my own, because that’s what I prefer, but that does mean I have the freedom to ride a stupid bike if I feel like it. I wouldn’t take it on any of the (rare) group rides that I do. Not because I care about the piss taking, but because it has different strengths and weaknesses, so doesn’t suit being in a group with lots of “normal” bikes.
epicyclo also makes a good point. Personally, I wouldn’t bother with a fatbike if my only (legal) riding options were trail centres and bridleways. It is the fact that I have the right to ride my bike (responsibly) anywhere I like coupled with the large expanses of untracked heather and peat moorland (which has snow on it for a few months most years) that makes a fatbike look like a viable option.
