Leaning buggy

clutchdoc - 24-8-2006 at 10:38 AM

I have been thinking about making a homebuilt buggy and it occured to me that I could make better turns and not slide out as much if the buggy leaned into the turn. It would of course have a stabilizing lock so I could ride two wheels if I choose to.
Before I spend the time and money on the concept, let me know what your thoughts are as a group.:thumbup: or :thumbdown:

Hey Clutchy,
If by "leaning" you mean the frame only, that's one thing.
Keeping all three wheels on the ground gives the most traction.

Then you'd consider weight.
How much does this add to the mass?
And where?

Then complexity...

Now we're talking about the joy of experimental fabrication.
A side-avenue of buggying.

The ability of the buggy to slide sideways without overturning (generally) is a control factor.
Scrubs off a ton of momentum/speed.

Define "better turns".
Contrast that to "better piloting skills".

Part of the game is to realize the most out of what we have.
Keeping the buggy utterly simple focuses on skills rather than gear.

I think I read this in a book.

Simple lean.... staggered the rear wheel with one out side larger wheel and tire. and one smaller inside wheel....

to complex :thumbdown:


sucks just to go round and around

ya know, that might not be a bad idea... kind of like a port or starboard bias. I was talking to Richard of Windjet fame, and he has both rear wheels pointing about 15 degrees one way so there is a fast tack and a slow tack. Maybe a specialized thing for record attempts... Not for everyday buggying tho...

Basically the bug has evolved to where it is cause it works, is strong, is cost effective, There's been many attempts at making the ultimate bug, ranging from titanium to kevlar, 2 wheels to 5, 2 wheels front 1 rear, it's all been tried, for some strange reason it just works better the way it is. The different ones that have worked good are usually super expensive.

Another question is how good of a buggier are you, if your a skilled rider, may be an idea to experiment, if your learning, get a basic bug and learn, then tinker.

The only other bug design that works suprisingly well is the Crab Buggy, seems to edge hard and you can change directions without going downwind, similar to an ATB.

I believe the concept of leaning is already in use by the crab buggy.

Hello Clutchdog,

sliding/drifting out in the turns would happen as much with a 'leaning buggy', weight and tyres being the same, since the centrifugal force would still be overcoming any grip you have on a given surface and send you drifting. Overall suspension helps a bit, awesome weight and bigfoots (no slicks) help a lot.

Drifting the turns is half the fun, isn't it?

I also like to modify my buggies. But most of mods involve increasing stability (so I can ride more powered up) and comfort (so I can ride longer) I consider the issue better traction when turning to be a non-issue. I agree with Apple-Jack...Drifting in the turn is half the fun.

But if you still want better traction, there are two far less expensive options to try. 1. bigger fatter tires like Bigfoots (the more tire in contact with the ground, the more traction you have) , or even knobbies (they will
cut down your speed however.) 2. More weight. Many buggier that I know actually attach weights to both the front and/or rear axles. The more weight pushing down, the less likely those tires will break loose.

These are easy and relatively inexpensive solutions that will give better results than simply leaning the tires (which as Apple-Jack stated, wont do much).

Hi Clutchdog,

Actuallly, something similar has already been attempted. It didn't distribute very well because it was quite expensive.

This axle exerts some more pressure on the upwind wheel

If you want, I can establish contact to the maker (last price I read was around 600 US$). Last thing I heard, the guy now works for U-Turn.

brilliant here it is in english


New ideas are born from enthusiasm,
they often remain on the hard distance of a close market, but they are so good sometimes, which they intersperse themselves despite all resistances!

How it Pascal Witthoff of ISidoor kiting with its One air - control axle will go,… we look at it us simply!

About two thirds of the arising forces in the Buggy affect directly on the rear axle, a hard cross course might it even still more be.
With the Tim Andre axle of Libre for the first time a fitted with springs axle in the Drachenshops emerged; … except a pure comfort gain on uneven reason, there were however chassis-technically no advantages, since with each bouncing also the fall adjusted itself.
Clearly further developed the vector axle of Libre then already showed up: By the parallelogram construction developed by Klaus Baumgartner remained the once stopped fall also when bouncing. Which could not be prevented also here, those wheels of the rear axle were loaded unevenly, the rear axle leaned in the horizontals to the Leeseitigem wheel, thus the wheel, which was turned to the screen. The drift uses in relation to a Starrachse clearly later, particularly however on that cross and überpowert on half wind course showed up simply the borders of a such construction.
The One air control sets axle of Pascal Witthoff exactly here.
According to the shears principle the Leeseitige, thus the loaded knuckle, takes up the load, and continues to give it over a central stored fulcrum, fine-proportioned over an absorber, to the luff-lateral, thus unloaded wheel.
The advantage: The typical tilting motion of the axle in the horizontals is missing almost, both wheels equally is loaded, the Buggy receives both sides more Grip, can on that cross more height run clearly and also überpowert on half wind course sets for the drift deutlichst later!



First pictures of the OneAirControl version 2.1, taken up to Sickels with the Buggyevent of the BKO!
To recognize still well, which is quite sumptuous the dimensionings,… however for a first version all right properly!



Beautiful detail photographs of the force shears with the central fulcrum and the absorber.
All construction units are from V4A and the complete axle are simply by removal of the central pin to be dismantled.


Here pictures of the version 2.2, which is to go in August to the sales start.
Well to recognize, the axle has clearly abgespeckt at overall height and weight and might in its dimensionings for instance be comparable with a vector axle now.


For the practice test of the OneAirControl by Jens on Römö the axle was co-ordinated again finely and received an absorber from the motorcycle range. Well, which already successfully in a CBR 600 provided its service, can become only better in a Buggyachse!

Desire on more??? Into the next Kite&Friends gibt´s a detailed practice test
and still more detailed information.


I find´ enthusiasm is ne class thing, if he leads to such ideas!!!

If you want something that'll be slightly more stable when lit up, how bout simply looking into different styles of harness setup. I've seen one from the UK that involved more of a seatbelt style strap going from the 2 buggy frame rails with loops at the middle, your QR attaches to the 2 loops. Basically, when the kite's overhead both straps take the load, when the kite's way over to say the left, the left strap ends up a hare loose, all load is put on the right strap and therefor the right/upwind frame rail. This will apparently give you more stability in the terms of roll overs and such, but doens't help much on the sliding. It does however allow you to load up the downwind rear wheel a little more which may help a bit for the slides. Then you hook up a tether from you to the QR, so if you ever come out of the bug somehow, the kites released from the bug as well. It's been done, tested and works fine. The fellow got stopped in his tracks though when he tried to enter races over there using the new setup.

Hi Popeye,

where did you find the translation?

Never really thought of using this function...

That explains the awkward reading :spin:
