Old anarchy bike concept, needing help from bike know-it-alls

**davi** · December 24th, 2003, 01:05 AM

this is an old concept i did for one of those DSG's

I want to redesign it so it's more practical. it's based off the akira gangbikes and the dodge tomahawk(http://www.factoryfat.com/images/tom..._1280x1024.jpg). here's what i want it to do....

Topspeed 350 mph
Accerlication: 0-60 mph: 2.5 seconds
Max Engine Speed: 6500 rpm
Very high speeds on gravel and broken concerte
Enough 'coushin' to land from eh... 10feet while going 300mph without having damage to the bike

I know NOTHING really about bikes. I know it needs whells and a seat.... and headlights. I don't know what the shape of a powerful engine would look like... i don't know where and how the whells need to be set either..

Basicly i want to design a highspeed dirtbike that can be used for unpractical combat.

**davi** · December 24th, 2003, 04:37 AM

Ok, i started over and this is what i have so far, i moved the front whell closer. Added a diagnol slice down the sides for desgn, not sure if you can tell where i'm going with it but i promise i'll make it look better. Tried to make it as aerodynamic as i could, while still having it look strong and 'rugged'

Great work!

About dirtbikes; basically, a dirt bike is an off road vehicle. The body is suspended fairly high off the wheels and it's got some heavy-duty shocks. Your bike comes closer to looking like a crotch-rocket because of it's set-up. You'd need a pretty flat road undernieth where as a dirtbike can go just about anywhere because of it's hight allowance undernieth and light frame. http://www.just-in.net/clipart/dirt/img/dirtbike.jpg

You have to ask yourself what you want it to do. Your rendering is absolutely fine. it's just a few things like the placement of the wheels in proportion to the body and the rear tire-guard that may be considered impractical mechanically. Again though, great work!

**davi** · December 24th, 2003, 07:59 AM

i totally see what you mean, it's suppose to be kind of an insanely fast dirt bike... i honestly had fun learning some of the mechanics of motorcycles and drawing it and all... but seriously....this design f'n sucks. i need to revamp alot of it.

**R_M** · December 24th, 2003, 08:30 AM

Davi, what you are asking this bike to do is impossible at the moment.
Not even GP500 bikes reach that kind of speeds, and they travel on very good road.
That kind of speed would probaly make the bike fly....
I am not sure of the phisics involved but I don't think it is possible on earth.

oh one more thing the rider has to wear something to cover his arms, other wise he will dehidrate very very fast at that kind of speed.

I know I am spoiler..:o

take a look at the big japanese bikes (hayabusa, ninja whatever) they are shaped like bullets, and are barely capable of 250mph. any faster and your arms can't hold a grip on the handles. there is a reason why the bosshoss bike doesn't have an official speed just an indicative number

**davi** · December 24th, 2003, 08:41 AM

well i know what your saying, but if it were possible i wouldn't be sitting here trying to create pretend ways for it to visually work :]

I just need it to look functional yet... not at the same time.

The akira bikes wen't at least 150+ and they used melee weapons at the same time, not practical at all, but visually fun as hell

**Idiot Apathy** · December 24th, 2003, 02:38 PM

My 2 cents and a nickel:

Aerodynamics would certainly be necessary, maybe bring in the front tire and lower the front of the bike.

If it is too hard to stay on the bike and hold onto the handles going 250+ then the bike would have to be redesigned. Perhaps change the sitting position to a more laid back approach (Think astronauts in a space shuttle, but not that extreme). Change the position of the handlebars, or change the steering all-together.

I get the feel that you want this bike to be designed or modified for Bosozoku gang combat, Akira Style. A scabbard would do nicely

.

Overall I think it would look better if it were longer and shorter.

The beauty of design is in the eyes of the beholder, good luck!

Thanks, the idiot.

**davi** · December 24th, 2003, 07:42 PM

how can something be both longer and shorter at the same time...?

I used the of the dirt bike( http://www.just-in.net/clipart/dirt/img/dirtbike.jpg ) for the whell placement, i'll try to make the front whell in closer but i'm afraid it will make it appear less...offroad.

I'm going to try to impliment more futuristic nonsense into design, so i can get away with saying that it goes 300mph

This game dropped in mind...

**davi** · December 25th, 2003, 01:49 AM

those links are hot, thanks man, i'm trying to stay away from closed tops and 'tron'like designs.

here's what i got so far...

i lengthed it, made the front 'stronger appearing, changed the backand gave it a fan of some sort.

if the anatomy of the chest/back looks odd, check out my first design, it's the same rider. My theory is that the helmet and the suit both create an aerodynamic arch, also, it's a parashoot, so if the rider does fly off for some reason he can use it to decent his...crash

Yeah, that's how things come out when I'm tired, I meant longer and lower to the ground.

Looking good, the rider certainly puts it into a better perspective.

**Al Ian** · December 25th, 2003, 11:13 AM

I want a motor cycle like that!

**davi** · December 25th, 2003, 12:09 PM

if i put the bike closer to the ground i'd be afraid it would mess up the fact that i want it to beable free fall from at least 10feet while going near top speed

**Idiot Apathy** · December 25th, 2003, 02:34 PM

Ah, well that changes everything. You might want to put a built in cross that comes out and stands erect and recites a prayer when they jump 10 feet at full speed.

Ha! J/K looking forward to what is still in your mind.

**Hunger_Artist** · December 25th, 2003, 05:23 PM

technical issue: at 300mph a well placed bit of gravel could take you down (assuming it was riding behind somthing)

im no expert, but maybe it should have jet thrusters somewhere too.

**davi** · December 25th, 2003, 06:31 PM

http://www.allpar.com/cars/concepts/tomahawk.html

max mph = 300mph
500 horsepower viper v-10

**Idiot Apathy** · December 25th, 2003, 07:54 PM

Unless I'm mistaken, and last I heard the tomahawk has never been riden. All the stats they have are simulated, like in a dynomometer.

**cartoonfox** · December 25th, 2003, 07:56 PM

oh my god!! no one is going to ride that. at least not reach 300+mph. thats just crazy! no one can be that suicidal and 'ard!!

... makes games like 'extreme G' etc seem all that more realistic!!

**davi** · December 25th, 2003, 09:47 PM

i'd ride one if it had a mounted machine gun and a plane that could pick me up for refueling.

**Idiot Apathy** · December 25th, 2003, 09:49 PM

Well yeah! Who wouldn't! Tell ya what Davi, get a sidecar and I'll be your gunner.

**davi** · December 25th, 2003, 11:54 PM

mmm sidecar not a bad idea for next design.

here's an update:

**winjer** · December 26th, 2003, 12:34 AM

I think you should sink the handlebar things into the chassis so theres like a little alcove that the guys hands go in. makes it more aerodynamical. Maybe the legs too. It would be like he has to wear the bike.

**Juice5942** · December 26th, 2003, 12:55 AM

The tires look too small now. Put two dirt bike tires together and they are about equal to the overall length of the bike.

I would say don't worry too much about the 10 foot fall, if you go too much for a dirt bike feel, you'll lose the "speed" look of the bike. Dirt bikes aren't meant to go fast, just like a jeep can handle rocks, but isn't much for top end.

I like where you're taking it though. Also keep in mind the way you see the bike taking the jump. If it's going to be a long, low jump, a crotch rocket can possibly land on both wheels at once if the jump is wide enough, but chances are that once it hits that ramp, it'll tilt backwards and the rider will have to touch down on the back wheels first.

The way you have it right now, it looks like if he did that, the rear wheel might just snap off.

Also, I'm curious as to what the thing is that the rider has on his back?

**davi** · December 26th, 2003, 05:59 AM

ok i'll do my best to fix the stated issues.

and juice, i'm trying to make this look like a fictional bike. i know that dirt bikes don't go 300mph, that's the point of this attempt... i'd just be drawing a bike if i didn't give it bizarre features.

**Idiot Apathy** · December 26th, 2003, 04:10 PM

Just a minor suggestion and a pretty big problem.

Minor Suggestion: If you like how it looks I'd consider bringing in the part of the bike where his legs/knees meet the chassis. May not be very clear, so make an indent in the middle of the chassis where his knees meet the bike.

Pretty Big Problem: He can't touch the ground with his feet! Eek! Perhaps you should put the seat at an angle like this \ only not as sharp. Or give him training whells

.

Looking real good davi, I'm getting excited to see the final concept.

Thanks, the idiot.

**gallon** · December 26th, 2003, 07:16 PM

I just saw some Harley documentary on discovery... I had a name for you but it slipped...sorry. So, do this , check out hanover and harleys on google. They have the biggest custom fairs in Da world. Pretty cool stuff, and the new european custombuilds looks really cool and could bejust what your looking for.

Adi granov have some slimmed bikes on his site, remnant-section (http://www.sofos.com/adi/), but I guess you already looked at those.

**davi** · December 27th, 2003, 12:23 AM

Idiot Apathy, your minor suggestion confuses me, but your major one makes perfect sense, thanks!

gallon: yeah that bike adi is fantastic, i wish he had more on his site..

**eviltwins** · December 27th, 2003, 12:36 AM

The rider needs to be WAY lower tucked. Rear swingarm needs to be a lot longer, and there should be an airfoil of sorts to direct air away form the rear tire, as that is a primary source of drag. And on a purely technical note, you would need a hugely overdriven final gear in your trans, a numerically low final drive ratio, or a very tall tire to hit 300 MPH with a 6500 RPM rev limit

I shift my bike at 10600 RPM's and it's considered a fairly low revving bike, when you look at the 600CC'ers that spin to 15K.
