Why cant I go over sweet jumps?

Trying to get back into trail riding and again plagued by a re-occurring, life-long issue . . .
Why cant I control my bike off of jumps ? The back end always drops and my feet start to unweight from the pedals creating a situation that has proven to be somewhat undesirable. How do you guys get air without this stuff happening? I try to 'twist'(?) the bars but that doesnt really work too well. Not looking for pro-monster type stuff, just clearing small table tops and 3' drops would be great . . .
Any tips would be most appreciated

crawl, walk, run...

Start out with some not so sweet jumps. Once you get a hang of those and build up your skills then move up to the sweet ones. Then after you master sweet jumps then enter the Red Bull Rampage.

Go clipless. That way your feet stay on the pedals. And rear wheel dropping a bit is way better than front wheel dropping.

Do you preload? If you don't have clipless pedals, you can level your pedals so they're at the same height and push down on them. If you have them flat and put the right amount of pressure on them, no side will 'override' the other. Even then, I'd suggest getting clipless pedals, just for safety.

It's been ages since I really jumped a mountainbike, but I just pulled the bars up and forward a bit to keep the pedals in contact with my feet. Similar to jumping over a skateboard or something on a flat road by jerking the bars up and forward.

Thanks very much for all these suggestions.
Im reading all of them. I consider myself a fairy capable rider but Im tired of rolling obsticles I should be getting air over.
I think I am going to start to devote some more time to some single-purpose repetition stuff.

Thanks again

I suck at jumping so I offer no real advice...just a disagreement with everyone who says to go clipless for jumping. 1) Much scarier to jump clipless, and 2) too easy to cheat and develop bad habits when jumping with clipless. A good set of pinned platforms and shoes should be more than adequate...if your feet are flying off of them it's a technique thing, not an "I need clipless pedals" thing.

You need to actively jump the jump, not just be a passenger on your bike. Technically the action is just a bunnyhop that happens through a grade transition. Preload into the face of the jump and then unweight off the lip. Practice practice practice.

I agree that clipless helped me a lot for small stuff. I would never want to do serious jumping with clipless, but they are great for what I encounter riding XC.

Sorry, bad, I know . . . .

'Nother boring question if anyone is still reading this:
How are 29'ers for air stability? I know its mostly rider, but do the bigger wheels spinning have a gyro effect or any weird physics stuff like that?
Cherokee Park in Louisville is my trail system if anyone reading this knows that area

That's actually a very interesting question...

You can see the gyroscopic effect of a wheel by taking it off the bike and spinning it while holding it by the axle. Try turning the tire while it's spinning. Kinda hard to, huh? I have only done this with a 26" tire so someone with 29" and 26" tires could compare the two. If the 29er is harder to turn, then the 29ers will have better (or worse?) air stability.

That's my guess anyway

Not to say that a 29er can't be jumped, but there's a reason you don't see DJ 29ers.

OP, please listen to Zephyr11 rather than this stuff. Having ridden clipless(almost all road) and having eaten **** trying to learn new things on my MTB, the last thing I want is to be new to clipless And stuck to the bike when learning to get decent air on a jump. Talk about an injury waiting to happen. There's a reason DH, Freeride, etc. riders don't ride clipless. The more air/higher the risk of a decent crash, the less you want to be attached to the bike.

First off, DH riders do wear clipless. This is not new or surprising. Second,clipless helps with bunny hopping and keeps the feet on the pedals. As the OP is having a problem with that, clipless is worth a try.

Perhaps racers. That I don't know. When I watch a downhill MTB video of people on rough trails with jumps and drops, they're on flats. OP said he's having a problem with jumps and drops, not bunny hops.

Jumping = bunny hopping. And OP is having a problem with his feet unweighting from the pedals. Which clipless will prevent.

less DH'ers wear clipless than ones that do
Pedal choice depends on terrain. Some places i would wear clipless all the time, but here i wear flats. It's hard to unclip fast enough when spinning in mud going up a steep river bank

I purposely stayed away from this thread until today just so I could be amused by the silly ***** people offer as advice. Listen to cryptid & Zephyr . . . and to 3speed telling you to listen to cryptid and Zeph and tune out the rest of the noise.



For the record, probably about half of DH racers go clipless and half don't; and the majority of DH riders are probably on platforms. Of the racers running clipless, it has almost nothing to do with making the bike more controllable and almost everything to do with (real or perceived) power transfer.

Why are we even arguing over whether downhillers use clipless? The guy's talking about jumping. Yeah, downhill guys jump as a function of their riding, and use it as necessary to get down the mountain, but someone please show me what DJers ride clipless. I mean, maybe there are a couple who do for whatever reason, so if you happen to find one picture, don't waste all our time by posting it and saying "HAH! SEE?!" but it's certainly not the majority.

Didnt mean to cause contention . . . I personally like Primos or Easterns and use them on all of my bikes. I'll try anything once though, twice if its good
I just want to be able to land small hoopty-do type launchs and clear roots without getting tweaked. I can wheelie for miles, in circles even, do stoppies and all other cool stuff, but getting nice clean airs seems to elude me for some reason. Im shopping for a new bike, too . . . Very excited about this coming summer !

This is all of it in a nutshell. You see below where it looks like I've picked the bike up under me. It's not exactly what i've done; but basically, you want the bike to pop off the lip while you bend your arms and legs and let the bike move up under you. If you don't and the bike pushes YOU up, you will start to unweight upward off the bike into a classic 'dead sailor.'






Practice cannot be emphasized enough. I used to be a terrible jumper: off-kilter take-offs, nose-high or nose-low landings, crooked landings . . . you name it. I worked on it. A LOT. I spent an entire afternoon of Sea Otter practice one year doing a three-jump rhythm section over and over just to get it right. Now I love to jump, although I still don't always nail it.

Be smug all you want, but landing 3 foot drops while trail riding is closer to XC than DH and a mile away from dirt jump. Most XC, trail, and AM riders use clipless. Clipless helps people with the bunny hop motion. Ergo, it's at least worth a try. Read the question, answer the question. It's not particularly complicated/

^^ Jumps and drops are jumps and drops, no matter the type of riding you're doing. What the others are saying is that jumping is a basic skill like a bunny hop or 'most anything else. All of those maneuvers should be able to be performed without the crutch of clipless pedals.
