Mountain biking is a massively broad activity. Back roads and back flips. No bike does it all well.
First of all, some clarification. What do we mean by “underbiked” and “overbiked”? Aside from a few variables I’d say it’s about a judgement of a bike’s suspension travel and its weight.
An audio version of this article is available to logged in users so they can put our goods in their ears.To be “underbiked” is to be on a short travel sub-14kg bike and attempting to navigate significantly rough and/or steep terrain.
To be “overbiked” is to be a long travel over-16kg bike whilst pootling around smooth and/or shallow terrain.
Because this is cycling, everything is tainted with a tincture of sadomasochism. We admire riders who are underbiked. We mock riders who are overbiked. We prefer riders who put restrictions on themselves as opposed to riders who prefer to enable themselves. Cyclists are weird.
Furthermore, the use of the prefixes “under-” and “over-” implies some sort of baseline. Some sort of norm. I guess this is where the fabled “trail bike” is supposed to exist. I know we’re all supposed to love a good do-it-all trail bike but in my opinion, trails bikes are exactly what’s wrong with mountain biking…

Mostly neither as I select the “right" bike for the route. If anything I’m more likely to enjoy being underbiked as that brings a bit more of a challenge without the requirement for excess speed/risk.
I only have one bike and I’m probably overbiked a fair bit and only really feel underbiked on pretty serious downhill stuff. It can be a bit of slog at times especially on flattish undulating stuff but I don’t mind.
I am about right I think.
I don’t ride such steep stuff anymore. I have never been a big jumper. My skills and bottle is the limiting factor on how fast I go on rough stuff – always has been.
A modern 29er, on modern 2.4 tyres, with decent damping is all the shizzles and basically means my 130/120mm bike is equivalent of older 150/160mm bike IMO from a capability point of view.
I ride local natural stuff and some trail centres, so Orange Stage Evo is just what I need.

So is the point of this, that everyone should ride a bike that weights between 14.0 & 16.0 Kg?
The wombles of Wimbledon were underbiked overbiked.
But they were at least wombling free
Definitely overbiked with seven of the effing things in the garage + two tandems + four motorbikes, God know why as I can only ride one at a time.
Edit – by this measure I suspect I’m underwifed though.
I used to be overbiked but ‘ve gone back to an xc bike (chisel fs 110/130mm) as anything else feels too slow compared to the emtb.
It doesn’t make a huge difference though, on group rides theres everything from rigid singlespeeds to 170mm enduro bikes and everyone rides the same stuff at a similar pace.
If it’s not too much climbing then I’m on the 26″-single-speed-rigid-no-dropper.
It (or rather I) can cope with the FoD stuff and a fair bit of natural Cotswold stuff, but for the big hills I need gears, so the Ti456 comes out.
When I look around at others, I feel under biked even on the 456, but when no one else is around then either bike is perfect for that moment, so I guess I’m in the ‘don’t care’ camp.
I should add that although I ride the trails, it ain’t quick, but it is fun.
Stopped caring about it awhile ago . . . just happy to be “biked."
I just ride my beady. That way I’m both under and over biked at the same time.
Think I’ve finally got it about spot on with a 120mm XC FS, 150mm trail bike and 130mm HT?
The trail bike can cope with everything I have the skill to throw at it and the XC is as quick as my old gravel bike at the other end of the scale. At the XC’s limit the trail is also capable so they overlap well. HT fits somewhere in the middle.
I happily have just the one bike, it is perfect for most of what I ride, but I might sometimes be over biked, sometimes under biked, but always happy to just be on the bike (and even happier at service intervals to have just one).

I dont know if Im under or overbiked. I just pick one of the 2 options I have and go ride it.
I only have older bikes, non of which have more than 100mm. I guess I might be under biked but I don’t really care.
Underbiked on my folding commuter.
Homeostatic on the FS.
Unless you are on a 100% fire road gravel ride, or doing lift served downhill; at some point on the ride you will be either under or over biked.
All depends on where your skills and interests lie. Just like the fabled one bike to do it all – you need to define what you want, and your answer will be different to everyone else’s.
