    Jumping on a rigid fatbike

    So when I bought my fat bike I peeled off a sticker that said "Warning: this bike is not built for jumps or drops greater than 2 feet in height". Well, a 2 foot threshold would ban anyone from almost any black diamond trails. Needless to say I've gone right ahead and put my fat bike through some pretty nasty treatment, but where should I start drawing the line?

    I'm not trying to do crankworx on this beast, I'm just trying to get the peace of mind of knowing what it takes to bend the fork or crack the frame. What's the first thing to go and how do I avoid getting into trouble? I have an SE F@R/Fuji Wendigo/BD fb5 frame.

    Depends on your skill level. Hans Rey could land a 15' drop on a road bike and do it smoothly enough to cause no damage. Me, I'd probably break any bike at 4'.

    I'm a clyde and I catch a little air on my fattie all the time. Doesn't hurt it a bit.
    But... My bike is all custom. Like stremf said, if you're skilled, you won't hurt it.

    Break yourself on a 4' drop you mean? I would hope a good bike can survive 4 feet of gravitational impact.

    Regarding the whole skill thing, we all try not to fight gravity more than we have to, but dropping is still dropping and not all jumps or TTFs can boast "soft landings when skilled". There's purely gnarly stuff out there which can just be abusive. I don't think Andreu Lacondeguy could run a fatbike down Captain Ahab without a scratch.

    It's the forks and wheels that your going to have to worry about. Already seen videos of those cheaper fat bike forks folding on landings. People do it but doesn't mean bike is meant for it. Also why they made forks like the bluto.

    I don't exceed about 18" with mine, I have carbon fiber forks but 4.7 tires to take up the force of the landings.

    If you had a better fork I'd be less concerned. But with one of the cheaper forks I'd be afraid of folding it off more than a 12" step.

    I call BS on that. Just because you don't see it break in the video doesn't mean he isn't subjecting it to stresses exceeding the design criteria. I think all those videos give you a false sense of what bikes can handle and how easy it is to do stuff like that. For sure, what they do is impressive, takes a lot of practice, strength, conditioning, but make no mistake it's abusive as hell. They might minimize their impact, but to say they cause no damage is a huge oversight IMO.

    This phrase is just about in any manual I've seen or somewhere in the fine print. Even downhillers /freeriders sometimes have this somewhere in the manual, which is absurd.

    It's basically protection of the firm against any kind of claims you might have after an accident.

    Yeah I agree--see the Fabio Wibmer video of him shredding Leogang on a city bike. The bike clearly has broken a hundred times during the project, but the video makes it look like it holds up just fine (almost).

    Oops maybe I meant Portal trail or whatever trail they practice on before Rampage.

    If you know how to PROPERLY do jumps and drops, you will be fine. Just remember, your legs and knees are taking the impact. Also, have a decent amount of air in your tires, or this could happen, good thing I planned on replacing these rims anyway.

    A week after I took my 9:ZERO:7 down the lift runs at Windham mountain bike park, I noticed a crack in the frame; I'm sure it's just a coincidence, though.

    I took mine down Windham too, got some funny looks from other riders. Was it a carbon frame?

    First thing to do is make sure you have a good health insurance plan, because you are going to need it sooner or later! My question is who thinks it's a good idea to take a super cheap BD fatbike off 4 foot drops? You are clearly riding the wrong bike or riding the wrong trails. Fatbikes are designed to ride on soft surfaces at moderate speeds, not to ride in a bike park on black diamond trails. It might not break the first time you take a 4 foot drop, but eventually it will....

    Nobody can tell you what that threshold is, as it varies widely. A smooth 125lb rider will have very different results from a 250lb bull-in-China-shop rider.

    It's all about the right tool for the job.

    You kids and your fact checking culture is ridiculous. See the big picture. Just merely making a point.

    By the way, never seen Hans Rey on a roadie. Plenty of him on the GT hard tail back in the day. How strong wheels are these days, even road wheels (mine are 32h and strong as MTB wheels), he prob wouldn't have issues, although it may take a few tries.

    And I'm sure all of you have seen Road Bike Party. He takes some pretty big drops in that vid:

    I have a couple cracks around my BB in my frame right now, but I could put together a pretty kick ass riding video where you don't see any of it. I jump and have raced many times. I'll continue to do these things, but I realize it's not a DH bike or a trials bike.

    Pfffft. I have a set of Hed's on my Echo that I bought 2.5 years ago with all of 200 miles on them that have hung on the hook with no issues what-so-ever. Good as the day I bought them and have held up great when I go out to the garage with a beer or cup of joe and stare at 'em. We're talking some serious stares here, not no girly glances. True as the day I got 'em.

    Alloy w 135mm rear. To be fair, my local trails are strew with rocks, logs and other technical features; I may have not had the best technique when I started riding that bike and the weight didn't help. I tend to ride through obstacles, rather that float over them...

    How soon before you'll be able to ride? No apology for derailling this thread, it needs it.

    https://www.facebook.com/pg/eswgames/photos/There's a bunch of shots of people jumping way more than 2-3 feet in this link. If the jumps are built right you can take big air easily.

    Okay that was seriously the funniest thing I've read all day. Maybe even this week.

    How come there still hanging on the wall ?
