The most effective fats bikes are cartoon-looking mountain bikes with enormous tractor sort balloon tyres. If you happen to fancy one, here is what that you must know.
Think about a mountain bike coming to life off a cartoonist’s drafting board. Nicely that’s a fats bike. Large balloon tyres ship gobs of grip and a sasquatch-size footprint within the dust. The big air quantity within the tyres additionally makes them surprisingly snug, even with out suspension, and meaning the frames may be less complicated with much less to go flawed. When you’ve tried fats, there’s no going again, or so they are saying.
The final tyre width window on fats bikes is 4in to 5in. Usually and traditionally talking, the rim dimension is often 26in. However there are actually 27.5in rim fats bikes popping out. And, as ever with fats bikes, there are people who’ve gone OTT and made 29in fats bikes. It’s arguably greatest to disregard rim dimension for now. Tyre width is much extra vital with fats bikes.
Something a lot narrower than 4in and also you’re coping with a Plus bike. If you happen to’ve already tried the greatest mountain bike fashions within the conventional scene, a fats bike could tick the containers you’re extra desirous about.

What are fats bikes for?
“Why?” is the flawed query. Fats bikes are all about “Why not?”
What are fats bikes for, although? That’s a surprisingly troublesome query to reply. Though it’s true that fats bikes have been initially invented for using throughout sand or snow, that isn’t the explanation why fats bikes exist now. The overwhelming majority of fats bikes are ridden on the conventional trails that you just journey any mountain bike on.
You may journey fats bike… wherever. Fats bikes are at the start about grip. Traction tractors. The fats tyres aren’t actually an alternative choice to, or various to, suspension. Don’t go for a fats bike for those who’re searching for a suspension bike expertise. Fats bikes aren’t greatest handled as bump soakers. They’re for hoovering up terrain. ‘Floatation’ is a generally bandied about time period.
Why journey a fats bike?
There’s one easy reply. A solution that trumps all different solutions: since you wish to. You don’t must justify it.
That stated, the marketplace for fats bikes is much from easy or freed from tech. When you go down the rabbit gap of fats bikes you’re shortly into the sophisticated compatibility-strewn world of Q-factors, hub widths, chainlines and super-precise PSI.
Initially, it’s nearly not price even excited about tyre tread sample and design. The sheer footprint of fats tyres is what generates the traction. Err on the facet of minimal knobbles although. When you’ve bought a couple of rides below your belt, you can begin to consider what kind of different tyre tread chances are you’ll want to check out.
As for sidewalls and tyre weight, don’t be tempted with the lightest tyres yow will discover. They simply don’t journey very effectively. They wibble round and deflect like mad. Additionally they provide no damping in any way to counter bike bobbing.
Tyre strain is the whole lot
Tyre strain governs how the fats bike will work together with the bottom. It’s a excellent concept to get your self a digital strain gauge. Large quantity tyres run at MUCH decrease strain numbers than regular mountain bike tyres; fats bike tyres run at round 10psi. Up the strain a few psi at a time for using firmer trails. Decrease it for looser or muddier circumstances. An excellent place to begin is 8psi. Suck it and see.
Attempt to bear in mind to verify your tyre strain earlier than each journey as some setups lose air faster than you may assume.
Hubs and backside brackets
The elephant within the room of fats bikes. Hub and backside bracket requirements are everywhere. As a result of you may’t match these outsized tyres into common mountain bike frames and forks, this has resulted in a scarcity of constant method to hub widths and likewise backside brackets (cranks must be set wider aside to suit both facet of the expanded uncommon stays).
It many it’s in all probability greatest to not fear an excessive amount of about it. No matter you go for you’ll be left stranded. There’ll be spares and upgrades for all requirements for fairly some time but.
That stated, if you wish to depart the choice of working a suspension fork in some unspecified time in the future, get a fats bike with 150 x 15mm entrance hub.
The rear hub width that seems to turning into the commonest is 197 x 12mm. In some methods this can be a little bit of disgrace because it results in actually particular huge Q-factor cranks (assume: John Wayne) however that’s the best way it seems to be going.
Some notes about Q-factor. Common mountain bikes have a Q-factor of round 170mm. Trendy fats bikes are coming with Q-factors hovering round 200mm.
It could really feel weird speaking about suspension when coping with fats bikes however, as we stated above, a fats tyre isn’t a substitute for the greatest full suspension mountain bike. Suspension and fats tyres do two very totally different jobs. A suspension fats bike isn’t a pointless factor.
A 4in tyre isn’t an alternate 4in-travel suspension fork.
Fats tyres are about amount-of-rubber in touch with the bottom. Fats tyres use their dimension to deform below strain (from above and beneath) to extend the quantity of tyre adhering to the path. They aren’t there to soak up tough stuff.
Fats tyres usually are not for absorbing bumps (though they do take in small path buzz admittedly). A great deal of folks assume that’s what fats tyres do. It isn’t appropriate.
Consider fats tyres for traction and suspension for management. Suspension has damping. Suspension continues to be the factor for controlling the fast after-effects of enormous exterior forces (bumps, laborious corners, G-outs and many others).
So, as with common hardtail mountain bikes, be happy to go for one with a suspension fork. We’d really strongly suggest it if you need a fats bike to be your solely/most important bike. RockShox and Manitou are the names to look out for right here.
That stated, for those who’re merely fat-curious or need a fats bike to turn into a part of your fleet of obtainable mountain bikes, there’s so much to be stated for saving cash (and weight and servicing) and going for a inflexible fork fats bike.
Regardless of what anybody might attempt to inform you, body materials has just one impact on the bike: weight. There’s merely no approach that any inherent journey attribute of the chosen body materials is detectable by 4 inches of rubber.
Go carbon when you have the funds and wish to save weight. Go titanium when you have extra money than sense and just like the look. In any other case simply go for an aluminium or metal body fats bike.
How floaty would you like your fats bike to journey? The precept alternative right here is 4in tyres or bigger-than-4in tyres. Not many riders are effectively served by tyres greater than 4in.
Except you genuinely are primarily using on sand or snow, don’t get immediately sucked into the temptation of the fattest tyres doable. They’ll be insanely sluggish and bouncy and can shortly turn into not-fun. And enjoyable is what that is all about.
4in tyre fats bikes provide the whole fats expertise with hardly any drawbacks or compromise.
Rim widths vary from something 50mm as much as loopy beamers of 100+mm huge. You actually do must match your tyre width to your rim width very rigorously. It’s this side that may find yourself being pricey for those who dive in to buying a fats bike too eagerly with out doing all of your analysis. Fats bike wheels aren’t low-cost.
For 4in tyres that you must pair them with rims of between 60-80mm huge. For fats bikes with tyres wider than 4in, rim width is an advanced enterprise the place single millimetres have an pronounced impact. Evidently, for 5in tyres we’d suggest not going over 100mm in rim width.
Not like on common mountain bikes, the place we might at all times suggest tubeless, with fats bikes ‘going tubeless’ is less complicated stated than achieved and the advantages are minimal at greatest. Certain it will possibly save a little bit of weight however not that a lot. And the additional heft of fats rubber is definitely a part of the journey expertise and efficiency. WOOMPH-ing your approach throughout the panorama is a giant a part of the expertise.
So though you may go tubeless, it may be difficult getting tyres to seal and should require outlay on a tubeless tyre inflator.
Resulting from their snow bike heritage – and present wilderness bike wannabe standing – you may generally discover cable actuated disc brakes on fats bikes.
To not beat in regards to the bush, cable disc brakes suck. Their one and solely benefit is that the may be mechanically/agriculturally bodge repaired in the event that they go flawed in the course of the Artic Circle. Are you going to be using within the Arctic Circle? No. Get hydraulic disc brakes.
How a lot to spend on fats bike
You get what you pay for, as with all issues in life. You will see that fats bikes being knocked out for very tempting costs. Very like with area of interest bikes like fixies, singlespeeds and even arguably BMXs, a budget choice may be very tempting. The issue is although, they gained’t journey very properly and so they gained’t final very effectively.
We’d strongly suggest fats bikes nearer the £1,000-£2,000 mark. From a recognisable and respected bike model. And buy it through a correct bike store who will assist you set it up and kind out obscure spares and many others.
