jobin Posted June 25, 2016 Share Posted June 25, 2016 I've seen a few of these bikes with monster big tires, tall and very wide, but have never understood the logic. I guess they are usually mounted on mountain bikes or special bikes. What gives and what's the merit/demerit of such tires? Link to comment Share on other sites More sharing options...
moonoi Posted June 25, 2016 Share Posted June 25, 2016 Look up fat bikes on Google. They are meant for use on sand/snow originally, large volume tyre with low pressure gives better grip. Sent from my turnip using Tapatalk Link to comment Share on other sites More sharing options...

Absolutely, have never understood their popularity in Thailand, there's hundreds of them at the Skylane even, although I suppose they are giving the rider a decent workout......

impulse Posted June 25, 2016 Share Posted June 25, 2016 Just out of curiosity, has anyone tried one on a Thai beach? Are they even allowed on the beaches? The concept looks okay- fat tires to keep from sinking axle deep, but how's the reality in Thailand? We used to MTB (and drive) on the beaches in Texas, but they were flat beaches and the packed sand surface was almost like pavement until you got to the dunes about 50-100 meters back off the beach.

AlQaholic Posted June 27, 2016 Share Posted June 27, 2016 (edited) Ohh! cool, beach race in Thailand, what a great idea. Wonder which beach would be the best? Jomtien up to the hill and then continue up Pattaya beach? would be about 4 - 5 k on sand. Then one would have to contend with all the beach vendors, umbrella sales persons and umbrella beach owners:) That would be an extra:) Edited June 27, 2016 by AlQaholic Link to comment Share on other sites More sharing options...
Hayduke Posted June 27, 2016 Share Posted June 27, 2016 Another factor is their appearance is so strange. Around town, people notice them and they turn heads. Some riders no doubt enjoy being the momentary center of "look at me" attention.. Link to comment Share on other sites More sharing options...

In Town Posted June 27, 2016 Share Posted June 27, 2016 They are also useful during floods. If the water is deep enough, you will sink to about axle-level and then float, and if you pedal fast enough the centrifugal forces will keep you upright, and the tread in the tires will provide enough propulsion to get you across. Not recommended for normal water transport, but works in a pinch. Link to comment Share on other sites More sharing options...

williet98248 Posted June 27, 2016 Share Posted June 27, 2016 These bikes and tires are for sand and snow or possibly mud. On pavement the skinnier the tire the better they roll and the less the rider effort. I suspect that unknowing or unsophisticated riders buy these bikes because they are different and they can be the center of attention. Or maybe they just want to be 'cutting edge' and 'trendy'. But they are working much harder than the skinny tire bikers and have to peddle harder to keep up (if they can keep up) with the skinny tire guys. Even knobby MTB tires will be faster on the pavement with less work. Because I am too old and unbalanced for off-road biking anymore I replaced the 1.95 knobbies on my MTB with skinnier road tread tires for less roll resistance. That wasn't enough so I bought a lightweight skinny 23 mm tire road bike. The bicycle equivalent of a sports car. I blow right by these fat tire guys on my 10 kg skinny tire road bike and the thought in my head is, "What are you thinking?!" Link to comment Share on other sites More sharing options...

bluebluewater Posted June 27, 2016 Share Posted June 27, 2016 ^ I guess that is just great except I'm not in a race and you are welcome to get wherever you are going sooner than I will if that is what you want. I do note that with bikes with the bigger tires that on these crappy crappy roads that we travel on that the ride is MUCH smoother. Link to comment Share on other sites More sharing options...
bobfish Posted June 27, 2016 Share Posted June 27, 2016 I've considered a fat bike purely to cruise along the beach at low tide and sunset, but apart from n+1 I really can't think why I'd do it. Last time I rode my 2.35 tyred MTB on the hard sand, it was fun. Afterwards, cleaning all that salt and sand from expensive components was not! Certainly, fatties look like a hoot, but slow, bouncy and unwieldy seem to be commonly used adjectives. Unless you ride somewhere you need all of that flotation, I don't think I'd bother.

bobfish Posted June 27, 2016 Share Posted June 27, 2016 And, a 29er Plus size [3" wide tyres] is probably more than enough. http://p.vitalmtb.com/photos/users/109/photos/90725/s1600_BT_20150416_untitled_shoot_047.jpg?1429910900 I recall playing with 3" wide tyres on on my 26in DH bike years ago.

jesimps Posted June 27, 2016 Share Posted June 27, 2016 (edited) I should think that these tyres don't pick up as many punctures. I seem to average about one a week where I cycle on my normal mountain bike tyres. You'd also need disc brakes with them at a guess.

aussiandrew Posted June 27, 2016 Share Posted June 27, 2016 I hadn't ridden a bike for years and wanted something a bit different when I brought my big fat tires bike some 18 months ago. I am big tall guy just over 100 kgs and wanted a softer ride over the as been said earlier pot holes and cracked in the roads and pathway. Todate very happy with it had to change the size of the seat. Link to comment Share on other sites More sharing options...

Turns out that centrifugal force is not what keeps you upright on a two wheel or one wheel machine. Read an article on it and it appears that if you start to fall one way or the other you make a slight turn correction in that direction to recover. Watch a guy on a unicycle. He is all over the place making huge corrections trying to stay upright. Centrifugal force only works in a circular motion. Link to comment Share on other sites More sharing options...
Global Guy Posted June 27, 2016 Share Posted June 27, 2016 I've been riding monster bikes on and off for a three years now and have been an avid mountain biker and road cyclist for decades. Yes, they were originally designed for snow and sand. But I like how much the tires absorb the shock from rocks, road imperfections, and going up and down curbs. The issue of resistance is determined by the tire tread and how you dial in the air pressure. I dialed them up so I didn't notice any resistance issues. What others may mistake with that is that the rims and tires are considerably heavier than the skinnier mountain bike tires so what they consider resistance from the tire on the ground might actually be the added weight. Up to 2x or 3x heavier than MTB tires. My first one had 5 inch wide tires and my second one 4.5 inch wide. Since the tires absorb more, there is also less chance of bending a rim. Lastly, I like the extra wide footprint for extra traction/stability. So, there is a considerable practicality to them if you like to ride. I don't use it for long distances because it is heavier than my other bikes, but for hopping around town it's fun. They do look different and are a fun conversation starter as well.

I have had five punctures in the two months that I have owned my road bike. Several punctures on my MTB. None of the bike shops seem to have heavy duty puncture resistant tires and/or tubes. Only cheap Chinese made crap. I have gotten fed up and ordered off eBay two Kevlar clad, heavy duty, puncture resistant Michelin road bike tires made in Germany. Also several puncture resistant tubes to go with them. The tires are called 'Gator Skins'. The tubes are by Continental tire. No more punctures, I hope. Shop in the USA is called Bikesmith.

Good reasons to have one. I have a regular MTB for errands and around the town and the skinny tire road bike tor the tours and exercise. Link to comment Share on other sites More sharing options...
Stevemercer Posted June 27, 2016 Share Posted June 27, 2016 I ride a normal road bike and used to get many punctures until I changed the rim tape. The rim tape that came with the bike was poor quality and allowed the inner tube to get pinched in the holes for the spokes. So if you are plagued with punctures, the first thing to try is to replace the rim tape (two layers may also help). Remember to keep your tyres at at least 90 psi. Unlike most western countries, Thailand does not seem to have a grade test on blue metal (gravel road fill) and you often get triangular pieces of stone. An inevitable pinch puncture if you hit one at speed. Link to comment Share on other sites More sharing options...
