Fatty Weight

Decided to weigh my bike today. 35.26 lbs (16 kilos) which I thought was not bad. Mongoose Argus Comp. I changed out the saddle, seat post (longer so that added a few grams), tires to JJs, pedals and converted to 1X (eliminating derailleur, frame adapter, cable, shifter and 22T chainring). Still has standard-issue heavy tubes so I think there may be another 2 pounds to be had there. Not much different than most full-suspension bikes, but, of course, far more rotating mass.

One day I may weigh mine, but why?. If you have a significant other who is fun, reliable and like to be around and are you going to weigh her/him?

35lb sounds about right.

Ya know, for an extra $4000 you can have on that's 10lb lighter.
OR, for an additional $6000 you can have one that's 15lb lighter.

I don't think ya need to tho.
Only weak people need super light bikes.

Grab a 35 lb fat bike and pedal it up a hill. Then grab a 25 lb fat bike and pedal it up a hill. The reason why will become apparent.

The size of your significant other has nothing to do with physics.

I've done the climbs, numerous times and yes it was more difficult, but it was also a lot more fun coming down.
Why? Because a simile can be informative, relative, comparative, but certainly no intention to offend the spouses

Yes. You purchased a bike shaped object.

That is highly unusual. Probably a few dollars more than the $300 I paid for mine

Some random reference data. Not sure if the reviewers actually weighed the bikes or just used manufacturer published weight (which is usually at least a pound optimistic). I'll have to weigh mine without pedals, water bottle and cage.

Only weak people need super light bikes*???

Do you read your posts as you write them or is it similar to this guy I know who is in court a lot these days sort of stream of consciousness sort of deal.

Heavy bikes don't have really many or any advantages in most cases and a watt is a watt if I am pushing 100 watts on a bike it is 100 watts, the heavy bike is just going to make it harder to sustain and get up to a higher amount (not that 100w is high) A lighter bike is more pleasant to ride especially if you have a fat bike with wide heavy slow tires I would rather have something lighter that is easier to move so I can potentially go further or have an easier time on sand and snow. If my fattie is a fatty I am more likely to sink in rather than float like a butterfly (and sting like a bee).

I haven't weighed mine yet but I would hazard a guess in the current state it is 13lbs but it has no cranks or wheels on it currently and very little fluid in the rear brake.I am sure it will be much heavier with the needed parts on it but it has gone on a diet removing all of the e-bike kit components on it so it should be nice a light soon.

A few more:

$4700 Otso Arctodus Ti SLX titanium, tubeless, rigid fork - 32lbs
$5850 Otso Arctodus Ti XT titanium, tubeless, rigid fork - 31lbs
$2400 Otso Arctodus, ChroMo Steel - 34.4lbs
$2500 Kona Woo aluminum - 33lbs
$1000 State 6061 steel - 39lbs
$1700 Salsa Heyday aluminum 34.5lbs
$3700 Trek Farley 9.6 carbon - 29lbs

** these are from reviews. Weights, of course, are variable due to frame size, specs, tube/tubeless, etc. That's why most manufacturers don't even play the game and won't publish weights.

The weigh weenie trend fell out of style 5 years ago.
Being in a fat bike forum makes it even less relevant.

I'll see if I can find my hanging scale and report.
I'm guessing 35-40.

My ICAN in size XL, with a Wren suspension fork came in at around 25 pounds. Cost was about $2,500 so pretty good for what I built.

I bought the frame in late 2019 just before things went to hell in a hand basket. Got a lot of the parts for cheap early in 2020 when people were expecting bike sales to tank. Yes, it rides very nice.

Would I have been just as happy with a 10 pound heavier bike? If I hadn't ridden the lighter one yes, I would have.

The only other Fat bike I have ridden was an Alloy Specialized and it was before I bought the ICAN. It was a lot of fun to ride.

^^^ That's absolutely astounding (fat bike + suspension fork + $2500) compared to anything else I've been able to find. What wheels does it have? I've only found data on 2 carbon bikes with a suspension fork - both were north of $5000 and around 30lbs.

I did a re-weigh minus the pedals and accessories (water bottle and cage) which seems to be the standard method and am at 34.08 lbs (ready to ride = 35.26). l'm thinking it will be 32.5-33lbs once I do the tubeless conversion. This was an $1150 bike when new in 2017. 100mm rims and 4.8 tires right now. All that said, I have no complaints with the way the bike rides as is - it is great fun!

I'm interested to see some more actual weights posted (i.e. weigh it with the scale) since about the only thing you usually see is marketing department fantasy weights or guesses of what somebody thinks a bike weighs. Some specs, pics and what you've done to reduce weight, if anything, would be helpful. It would make for a nice database for those searching for a new bike or looking for ways to save some weight.

State has come out with a new aluminum frame bike:

$1000 State 6061 Trail+ aluminum frame - 39.9lbs (manufacturer claim). And the same weight as their old steel-frame bike.

Your bike's weight sounds about right. Its fine.

Don't pay too much attention the the responders here. Some of the claims about bike weights and/or claimed total costs are typical internet BS.

My Wednesday is somewhere around 35 lbs ready to ride. Steel frame, rigid, full fender coverage (rear, front, downtube), dropper post, bottle cages, pedals. That's 3 lbs heaver than my Canfield Tilt, a fairly burly FS bike. The Wed also cost about 1/4 what the Tilt did. It does not really hold me back in any way. Yes, I have owned much lighter MTBs (my bikes were nearly 10lbs lighter in the 90s). Yeah, lighter is nice, but It really makes little difference to me on the Fattie. I am sure as hell not going to spend the extra $ on CF stuff for that bike. Though I will likely go Al over steel for the next one.
