my jumps are tall
but what makes them even taller is the dippers inbetween

CMcMahon

WTF are "dippers"?

Prozakk
03-13-06, 09:33 PM
I just made one where I stacked landscape timbers & then covered it with a foot of dirt.

dig out a dip between the landing and the takeoff dips below the ground making the jump taller and a dipper makes you keep your speed better.

CMcMahon
03-13-06, 09:49 PM
So basically what you're saying is to make a weak little racer "double" that you can manual over.

This is a dirt jump (not a particularily large one, but at least it has an actual gap):

jackmcjack
03-13-06, 09:54 PM
no
a rythem of gap jumps have a dip between the landing ramp and the 2nd takeoff
the 2nd takeoff

Expatriate, do you happen to know if English is the primary language in Australia? I thought it was, but I gues I was wrong.

Are you talking about a roller in front of a double?

jackmcjack
03-13-06, 10:07 PM
you pedal up 2 the jump you jump the jump getting air you land on the down ramp and then you go down the dipper..................... then u go up the other side of the dip and you go into the air landing on another down ramp this is called more than one jump in a ROW

CMcMahon
03-13-06, 10:15 PM
Are you trying to insinuate that the double in that picture is the only one in the set? It's not my fault that you can't just phrase your comments in plain English, without some sort of semi-******** jargon.

i like the look of that jump, do you those trails? do you have any good photos of yourself? i mean riding a bike just for the record

CMcMahon
03-14-06, 03:58 AM
No, those trails are in the Hollywood Hills; my friend Tyler goes to school down there, so he rides them. The trails that I'm working on right now are much bigger than that.

And, for the record, there's a link in my signature for a reason.

I don't see what's funny about that. That's probably six times as long as most of the other kids on here have been riding for.

sorry i dont click on everyones signiture, and i dont even know your name how am i supposed to know who you are? probably another stupid question but

lets not generalise about australians here, most or some of us arn't illiterate

I'm older, thus it's funny to me. '73 is when I started riding.

I started riding in 94-ish but since I was 5 I wasn't really serious about it..

Our dirtjumps on average are around a 30 foot gap.

Thats weak

CMcMahon
03-14-06, 09:52 PM
Well, that's nice to know. Note the fact that I very clearly stated "not a particularily large one, but at least it has an actual gap"; the point was to shwo the difference between an actual double and the (much more) weak racer-style jumps on JMJ's website (Copy/Paste Into Browser Window (http://jackmcjack.tripod.com/sitebuildercontent/sitebuilderpictures/race3.jpg)).

edit: I also like how every single post from you so far, DirtKing, has been completely worthless and pointless.

Once I can find my digital camera connector, I'll show you guys an 8ft jump me and my buddies made. It took about two weeks.

CMcMahon
03-14-06, 10:09 PM
That's funny, because you called the jump I linked to weak, but yet it's... eight feet.

Interestingly enough, this one is also... eight feet.



And the set we're building right now at our trails? Eight-foot double. Eight-foot double with a four-foot stepdown. Thirty-foot lefty-hip. Twenty-foot double. Eight-foot hip. And more. And probably more in front of that first one, too.

If thats 8 then are must be like 10

CMcMahon
03-14-06, 10:18 PM
Eight-feet would be an approximation. It's not like I went out there with a tape measure. It's about two bikes long, wheel to wheel.

Where might these jumps be located?

In the land that time forgot. Quite literally.

Most jumps we ever build get plowed, because some stupid little kids end up trying to do it, and break their arms. Then they try to file a law suit on the city.

Expatriate responds - The US and Australia are two countries separated by a common language.

And I've been riding since nineteen seventy something.

ive decided that ignorant is better than illiterate
illiterate:not able to read or write
ignorant:uneducated in the fundamentals of a given art or branch of learning; lacking knowledge of a specific field

Illiteracy is ignorance, in case you weren't already aware.

In your list of jumps, which one is the one in the pic. I know looks can be decieving. I have a small 12 double. It's not very high, you hit it at speed. The tops of the doubles really don't look that far apart. But from take off to landing is 12 feet. I'm not into big ole gapped doubles. I'd rather have a jump I can come up short on, and that my kids can easily ride over withough jumping. Tabletop jumps are prefered on my own track.

we did similar but with oil drums stacked on their side covered in dirt.less dirt less work eh!

None of them. That step-up is in a different pack, but leads into the last hip in the mentioned set, and you can can get to it by making a left turn instead of going straight towards the unfinished pack I talked about.

And I don't have a problem with tables; I was out at the Psykopath "training facility" the other weekend, which is basically a pack of eight or nine lipped tables. They're fine for getting back into riding dirt, but they just don't compare to the real deal.

JMJ your website is totally useless.
On your little bike review, your gradea bike on speed? and looks? Oh thats very important. Seeing as all 20" BMX bikes have the same size tires and all come stock with the same gear ratio they go the same speed. The rider makes the speed.

Oh and after reading your trick page I think I'm ready to enter the X Games. I mean now I can do "Flick Outs," flairs aint got anything on those. Then I can enter the flatland competition and do some wheelies, or should i say "monos." Those are not even considered tricks. And you say you need alot of air to do x ups, then how come i can pull them off curbs without even hopping??

less dirt = more work when you dcide to fix up the jump after it gets messed up

mude
03-16-06, 09:16 PM
for take offs the more dirtyou have the better
for landing you just need a couple inches covering filler

just so u know bmx bikes come with different gear

and did the page say anything about entering the x games huh?!
by the way an x up of a curb is alot different to 10 ft in the air!

no it isn't. if anything, an x-up with a lot of air is a little easier.

before you talk smack why dont you put up some pics of yourself

I_Suck_At_BMX
03-17-06, 02:45 PM
Im not saying I'm a great biker, i mean ive fell hard off a jumps that are alot smaller than 8 ft. Hell, I've broke my nose and knocked my self out on a 4 footer. However I dont go around preaching about the right way to do stuff and giving info on stuff that doesnt exist acting like im professor bmx.

For Instance He wites explanations about tricks that includes one actual trick. He should have a review for manuals not wheelies, a wheelie isnt going to help you anywhere unless your trying to impress kindegardners. As for what he calls a "flick out" its not really a trick. However it is something good for a newbie to do to get used to manuevering a bike in the air.

Why I actually went off is becuase I'm sick about people saying "get this bike its fast" and that stuff and he has a ton of stuff like that. He rates a WTP on looks (what good is that going to do you), Speed (which is all generally the same since stock bmx bikes tend to have the same gearing 44/16, 39/14, 36/13, 33/12, 30/11, 28/10, 25/9, or 23/8. The only thing that could make a slight difference is crank arm length, however my friends cranks is 5mm longer and we are still neck and neck when we race. As for the gearings, there might be more but i only listed what I can think of off the top of my head). He also rates a bike on spin. Everybike spins, you make the bike spin.

As for pictures, I dont have any. The only camera I have is my dads and he wont let me leave the house with it.

And I'm sorry for going off on you, I guess you really didnt deserve it.

*Note* 44/16 39/14 36/13 33/12 30/11 28/10 25/9 23/8 are all the same.

CMcMahon
03-17-06, 03:00 PM
They're not the same (except for 44-16 and 23-8, and 44-16 handles the torque much better), but they're close enough so that the difference in negligible.
