The Kiteboogie: Keep Your Tush 7 Inches Off the Ground and Go Way Too Fast




Introduction: The Kiteboogie: Keep Your Tush 7 Inches Off the Ground and Go Way Too Fast

About: the adventure continues

Let's face it: kites are awesome. Especially steerable kites that can pull you off the ground. While last weekend was pretty enjoyable(snorkeling with harbor seals in la jolla and sleeping on beaches), I decided I needed a higher-velocity activity this weekend. The plan was to build a basic kitebuggy from scratch and go out to a dry lakebed and get pulled around much too quickly by a kite. And it worked! I'm sooo sore!

This instructable is about how to build a simple kitebuggy. It cost me about $100 total, and the only tools I used were a cordless drill and a circ saw. No welding required!

Now, after riding this buggy and looking at some kitebuggy websites, I immediately got lots of ideas of how to make it better. When I got back home, I immediately ordered a cheap mig welder and started filling up notebooks with sketches. Still, this one's pretty good, it'll move at an exhilarating speed, especially if you haven't kitebuggied before, and it's quick to build--probably a few hours once you have everything

woohoo! Kiteboogie on! There are some great kitebuggy pictures of us boogieing that my friend Dick took at

*as I'm publishing this one, I'm working on the next version. Let's just say I thought there was too much friction in this one, and I'm playing around with some tarps and gas-powered leafblowers. Tune in in a few weeks and see what happens!

Step 1: Disclaimer

So, I strongly suggest that you use this instructable as a guide, not a bible. Play with a kite a bit and think about what you want in a buggy before you build it. My next designs will be three wheeled and made of welded steel tubing, with a lower slung seat and a longer wheelbase

The most glaring flaw with this design is best illustrated by the story of my first attempted ride:

I had wanted to go kitebuggying for a while, so I picked out a dry lakebed in the california desert, called a bunch of friends and told them we were going buggying, let's all meet there at such and such a time. Of course, I didn't have a buggy yet. A couple days before we were supposed to go out, I figured I should remedy my buggylessness, and so a mcmaster order and several trips to the hardware store later, I had a sturdy buggy.
We drove out to El Mirage dry lakebed, an incredibly flat 5 mile x 3 mile lakebed an hour and a half east of LA. I was driving with my friends Jesse and Jessica. We could tell when we were close because we couldn't see anything, since we were suddenly enveloped in a giant dust storm. The forecast had predicted 15 mph winds, but they felt upwards of 25. Pretty exciting. My kite was a Best 2.2m trainer on 75' lines.
For a while, it was pretty exciting. We drove out on the lakebed and met up with my friends Dick, Jenny and Scott. Wierd ATVs and dirtbikes were roaring around somewhere on the lakebed, quite close from the sound of it, but we couldn't see them because the dust storm limited visibility to 10' or so. You could hear ethereal redneck howls drifting on the wind, punctuated by backfires and the smell of exhaust.
When we got out of the car, we were instantly blinded by whipping dust. Fortunately, I had snorkel masks from last weekend's adventure, so we were all soon outfitted in the height of fashion. It was pretty windy, so we amused ourselves by putting up the trainer and getting the bar ripped out of our hands by the wind. Scott got pulled a good 10' before letting go of the kite, and I sprinted about half a mile in zero visibility in the vague direction I thought the kite went, praying that the dirt bike maniacs wouldn't run me over. While I was out running after a kite, some mutant redneck came roaring by our cars in a huge pickup truck, bouncing over 3' bumps and shedding car parts. Things were literally flying off his car, important things like the bumper and some lug nuts from the tires. He didn't seem upset about it, just gunned the engine and roared on out.
After a while, the dust died down a bit, so we put the buggy together. I put the kite up at the edge of the wind, pointed the buggy vaguely downwind and got in. I tried to put the kite into a figure 8 pattern, but it got instantly ripped out of my hands and I had to run after it again.
We were getting tired of the kite getting pulled away, so we decided to make a harness to clip it onto the buggy. We used some tie-downs and rope to make a system similar to the hook-and-loop kitesurfing harnesses use. I put the kite up again, sat down on the buggy and hooked the kite onto the buggy. "A-ha! I thought. Now there's no way I'll lose the kite!" I put the kite into a figure 8. It promptly lifted the buggy and me up into the air and flipped us over. I reached out a hand from the rubble and crashed the kite. I felt glad I was wearing a helmet.

Well, now it was time for reflection and analysis. It seemed that catastrophe struck whenever I put the kite into a figure 8, or more accurately, moved it across the wind with any speed. My solution was to not do that any more. I also felt that there was a certain angle between the kite lines and the buggy's direction of motion that I should not exceed, lest I flip the buggy. This angle seemed to be about 60 degrees on either side. I also didn't like the idea of clipping the kite onto the buggy--it seemed like a bad idea to not be able to depower (drop the kite) in a hurry if I wanted to. Next time: some depower system involving shock cord!

Feeling emboldened by my new revelations, I pointed the buggy downwind. By now, the dust storm had cleared and there was a brilliant blue sky overhead, a steady wind and a gorgeous view of the mountains. All of us had some amount of cuts and bruises from wrestling with the kite. Scott, in particular, had rambo-style cloth bandages on his knees. I'd lost some skin on my fingers from having the bar torn out of my hands. We were all covered in dust.
Anyway, I pointed the buggy downwind, put the kite up at the edge of the wind and sat down. I kind of made little scalloping motions at the wind's edge, just enough to keep 20-30 pounds of tension on the line. The buggy started to roll forward, and the kite instantly started to drop. I steered a bit upwind, keeping the kite in the same spot and the tension picked up, as did my speed. It was then I remembered that Scott was wearing my helmet.
I realized pretty quickly I could control my speed well enough just by putting the kite out of the wind and pointing the buggy upwind to slow down. Speeding up was not a problem. After a while, I grew bolder and tried a tack. I got a nice burst of power as I came across the wind and suddenly I was going 15 mph and bouncing over mounds of dirt and I sped across the desert. I became acutely aware of my lack of helmet. I figured this was as good a time as any to stop, so I let go of the kite, steered upwind and then got out and ran after my kite. Success!

Later on, we all got to buggying around, with a pretty high success rate. At one point, while Scott was making adjustments to the buggy, I was holding the kite and enjoying bringing it across the wind in a high speed dive and letting it pull me ten feet into the air. I grew bolder, jumping with the kite and cutting harder and harder turns. Eventually, I put the kite into a very fast dive, and the resulting line tension had roughly equal components of horizontal and vertical force, resulting in my flying 15 feet into the air and turning a rather surprised somersault before landing on the ground in a heap and then running after the kite, which got loose. Now I'm kinda sore.

Anyway--the buggy shortcomings:
The main one is that the distance from the point the kite is attached(your arms) to the leeward wheel is only half the axle length, or 1.5 feet when the kite is 90 degrees to the buggy's direction of motion. This makes the buggy really easy to flip if the kite generates any pull. I definitely wish I had a wider wheel base.
Fortunately, this is a pretty easy problem to manage--never turn more than 60 degrees off the kite lines, and the buggy is perfectly stable. You don't really want to with this buggy anyway--you won't get any pull in your direction of motion, and you'll be doing a lot of work flying the kite and not getting anything out of it. At my current state of limited knowledge, I'm thinking the best 'point of sail' is for the kite to be 45 degrees from your direction of motion, maximizing both line tension and pull in your direction of motion. If you do find yourself at a higher angle, just don't power up the kite.

Also, some usual kite safety stuff:
Kites are hella powerful. Respect 'em. I'd flown trainers a bunch (50+ hours) and this was by far the strongest wind I'd experienced. I was very glad the kite wasn't any bigger.
It's definitely worth getting acquainted with a trainer before you try the buggy. By 'worth' I mean necessary. It's a lot of things to be thinking about at the same time, and it's good to have some fundamental understandings of all of them.
The general premise of kitebuggying is the same as sailing, so go out and sail a boat around for a bit, and everything on a kite will make more sense.

p.s. isn't this photo awesome? I feel like I should be running around with stillsuits and thumpers.

Step 2: The Buggy Itself

So, I wanted to make this buggy. The general requirements were: foot steerable, low to the ground and wide.
I'm still pretty new to LA, and I haven't accumulated metalworking tools yet, so most of it would have to be wood.
Also, there were bonus points for making it come apart easily and go on/in my prius.

I eventually settled on a four wheel design with 14 inch wheelbarrow wheels, solid steel axles and a plywood/2x4 frame. The final buggy was about 5' long and 3' wide.

p.s. See those bandages Scott has on? Those are learning bandages. Wear pants, helmets and maybe knee and elbow pads. I'm excited about getting an ugly leather trenchcoat at a thrift store to make my skin un-scrapeable

Step 3: Parts!

I could have got pretty much everything from my local hardware store, which is totally kickass--True Value in pasadena on Fair Oaks next to the 210. I spend half my waking hours there.
As it was, I put in a mcmaster order before I realized how much stuff the hardware store had.

Here's a list of parts I used:
4x 14" wheelbarrow wheels, 3/4" shaft
2x 3' long 3/4" shaft, general purpose carbon steel
8x shaft collars for 3/4" shaft.
4x 3/4" U-bolts with long (3") threaded ends
1x flange for 1" i.d. diameter threaded pipe
1x 1" diameter 2 inch long pipe nipple, threaded at both ends
1x flange for 3/4" i.d. diameter threaded pipe.
1x 3/4" diameter 4 inch long pipe nipple, threaded at both ends
3x 3/4" tee fitting
2x 3/4" diameter 7" long pipe nipple threaded at both ends
1x 3/4" inner diameter galvanized washer.
2x 2'x4' 3/4" plywood
2x 2"x4"x8' two by fours
8x 1" 1/4-20 bolts and nuts
a box of 1 3/4" wood screws
some 1/16" galvanized steel strips

All this came out to ~$100. If you have a decent junkpile you could probably do it for cheaper

Step 4: Building It: the Rear Axle

Moving right along, let's build it!
Put the wheels, with shaft collars at either side onto one of the axles. Line it up so that the outer shaft collars are flush with the ends of the axle.
Now take a tape measure and measure the distance between the inner shaft collars. Cut a 2x4 piece that length.
Now, on your 2x4, measure in about 6.5" in from either end. This is where you'll put the U-bolts that hold the shaft in place. Mark the spot.
Use the bolts as a reference and making sure they're centered, mark the spots to drill.
Drill out the holes for the U bolts. Go ahead and bolt 'em in place. Now slide the shaft through the two bolts, and go ahead and put the wheels back on, wheel collars and all. When everything's lined up, take a wrench and tighten down the nuts on the U bolts well. Put some threadlocker on 'em, too. My U bolts were too short to clear my 2x4, so I kinda chiseled a hole into the 2x4 a bit to bear the nuts. I actually think this was a good thing, since it let the 2x4 rest flush with the plywood that comprised the cart body.

Sweet! You have a nice secure rear axle!

Step 5: How Long Are You?

Now is a good time to get dimensions for the cart body. Sit on the edge of a plywood piece and see how far out the tips of your toes are, with your legs straight. Measure that distance. I'm about 3.5' from my butt to my toes. Take about .5' off that distance, and that's a good spot for your steering column. Measure off that distance and mark it on your plywood.

Leave about 6" beyond where you'll put the steering column and then trim off the plywood beyond that point.
If you like, you can taper off the car body--leave a width of 6" or so at the tip for the steering column, but feel free to make whatever shape you want, as long as it'll be comfy to sit on.

woohoo! You have a body!

Step 6: Build the Support Frame

Remember the length of your legs you measured in the last step? You took 6" inches off that to figure out where to put the steering column. Take another 6" off, and cut a 2x4 to that length. This will run the length of your cart, under the plywood, to add support.
Find the center of your rear axle(take the wheels off--it'll make the rest of this easier) and line up the 2x4 piece you just cut so it's centered.
Now, take those galvanized strips you got at the hardware store(I don't know what to call these. anyone?)
Bend them by hand into 90 degree angles, and then using woodscrews, screw them into the rear axle 2x4 and the piece you just cut. Do this on either side of the joint.
These galvanized bits won't hold the angle to 90--the plywood will do that when you put it on top, but they will keep the joint from pivoting or flexing downwards much.

Well cool--it's coming right along. All you really need is a front axle and steering

Step 7: Attach the Support Frame to the Car Body

Line up and center the rear axle with the rear edge of the cart body. Liberally using woodscrews, and making sure that the support frame is square with the cart body, attaching the cart body to the support frame.

Step 8: The Front Axle

For the front axle, measure the diameter of the 3/4" flange. Add 2" to this number--that'll be the width of your front axle. Cut a strip of plywood this width to the same length as the 2x4 from your back axle.

Measure in 6.5" from either end of the plywood strip and mark the holes to put in the U-bolts, the same as you did for the back axle. Also, mark the center of the plywood strip.

Bolt in the U bolts and put the axle through them. Go ahead and tighten down the nuts and put on threadlock. Now, center the 3/4" flange over the center mark you made, and mark location of the four bolt holes. Make sure the holes will clear the shaft on the other side.

Drill out the holes and mount the flange onto the plywood. Use the 1/4-20 bolts and tighten 'em down real good. Put some threadlock on the nuts.

sweet! You've got a front axle.

Step 9: The Steering Column

Now you need to drill a clearance hole for the steering column to come up through the cart body. The clearance hole should be 1" to clear the 3/4" pipe. Drill the hole at the mark you made for the steering column on the plywood cart body. Put a piece of 3/4" pipe through the hole and make sure it moves smoothly. File out the hole a bit until the pipe can rotate pretty frictionlessly.
(I know my hole is ugly, but it just had to be a clearance hole and I didn't have a jigsaw. I've since bought a jigsaw--I actually just got back from the hardware store)

Now center the 1" flange fitting over the hole you just drilled and mark the four bolt holes. Drill them out and mount the 1" flange onto the cart body.

Screw the 2 inch long 1" nipple onto the flange

Step 10: Putting on the Front Axle

Screw the 4 inch long 3/4" nipple onto the flange fitting on the front axle. Put the 3/4" washer on over the nipple. Now, lift up the body and put the pipe coming off the front axle through the flange fitting and pipe on the body. Now you can put it back down.

Screw on the tee fitting onto the 3/4" pipe. Put the 7 inch segments of 3/4" pipe on either end of the tee, and put tees at the ends of those pipe segments. Your steering column is now complete!

Step 11: Ride It Around

Well, the buggy is now pretty complete. Hop on and ride it around. Get used to steering with your feet. Get a feel for it. I stomped on mine alot to make sure it was sturdy

One thing that's very important to check for is the travel of the front axle. When you steer all the way in one direction, does the axle hit the support frame, or do the wheels run into the cart body? If the wheels run into the cart body, that's no good--they'll bind easily and that's a good way to flip or skid the cart. If that's the case, you'll want to put in stops to prevent that from happening. I screwed some 2x4 blocks underneath the frame to act as my stops.

The last thing you need is a seat. I made mine out of the remaining plywood and 2x4s, but if I had to do it again, I'd do something else.
The important parts are a backrest to brace against and some side railings to keep you from getting pulled out sideways. You can use whatever kind of seat you like. The wood one worked for me, but I wish I'd kept my seat back lower.

Step 12: Outtakes

For anyone designing their own buggy--one major tip:

The first bearing I planned on using was a lazy susan bearing. My assumption was that it was only a thrust(axial) load on between the front axle and the body. I built that version and took it out rolling on the streets near my house. What I didn't realize was that when I push on the steering column to steer, I add a significant radial component, and lazy susan bearings are not built for that. All the balls fell out of my bearing and the steering locked up, making the cart head (to my dismay) down a hill (I live in the mountains, so this is a non-trivial problem). A lot of designs for braking mechanisms went through my head, but I settled on the most practical and grabbed onto the rear wheels as hard as I could. My hands were instantly pulled between the wheel and pavement, where they made excellent brakes. A bit of blood loss later, I was shlepping the cart back home, my lesson painfully learned. The picture was after I washed off--there was a fair amount of blood.

Another thing worth thinking about is that you want to keep your steering column as short as possible. The longer it gets, the more stress it puts in the bearing, and you don't really get any benefit.

What's the weight limit for the vehicle??

That bepends how you build it.

This is really cool. I have no plans tomorrow, and I want to make a version of my own.

i will do this... i have an idea to use the remains of an old go kart, which will make everything safer, due to the fact that it has a roll cage, albeit a flimsy one.

If you go the hovercraft route, you'll learn something about why sailboats have keels and those wheels have to be pointed in some other direction than put up pictures, though.


Reply 12 years ago on Introduction

However, a hovercraft with 2 "keel" wheels that only provide enough side force to maintain a heading would probably have less drag than a buggy with 4 wheels digging into the sand. It could be the vehicle equivalent of a small planing sailboat vs. a large displacement hull.


Reply 12 years ago on Introduction

yeah, that's the general idea. I'm calling it a hoverproa and building the first full version this weekend (I built a few small gas-powered hovercraft yesterday that were able to support me). It'll have two wheels, each on arms about 6' long coming off either side of the main hoverboard. Both wheels are off the ground when I'm unpowered or doing a dead run and are pretty analogous to the ama in a real proa (although is an ama a windward hull?). On a reach or upwind tack, the leeward wheel will dig into the ground and let me maneuver without slipping downwind. Steering will work by pivoting the leeward wheel, and I'm still working out an elegant linkage or other mechanism to let me do that. I'm sure it'll take several iterations to get something that works well, but it seems like a buildable project. The original reason I moved to hovercraft was that I wanted to put a suspension in my next buggy, and a hovercraft is possibly the cheapest full suspension system, with the added bonus of removing almost all static friction from the buggy. Plus, saying 'kitepowered hoverproa" is just ridiculous. Ridiculously awesome! enough spoilers! Tune in the weekend after next for pictures of us taking the hoverproa and a few new buggies out to the desert!


Reply 12 years ago on Introduction

um... do you mean a hovercraft powered by a kite? Also, how could someone do something like this without much wind? if its a bigger kite, how big? its not always windy here in ma... help appriecated. (sorry about spelling)


Reply 12 years ago on Introduction

I mean a hovercraft that has separate engines to provide lift, but gets its thrust from a kite. In general, if you're going to use kite power, you need wind. Yeah, you could have a bigger kite in lighter wind, but I have no way of giving you an answer without knowing what kind of wind speed you're talking about. Generally, I've found that for land sports, you can get by with about 10mph wind and a 2m kite, but you're not going to go anywhere fast. Get some good ~15mph-20mph wind--there's plenty on the coast in MA, and then you can use smaller kites and have much more fun. I guess what it boils down to is that the simplest way to have fun kiting is to find places and times when there's good wind


Reply 10 years ago on Introduction

a hover craft would be cool, but you would only be able to go down wind since there is no friccion with the ground to move parallel to the wind, there for you would have to walk back to where you started

I just realized that I have almost enough junk to build one of these. Fun fun fun!

what if you put another larger parachute over you kinda like a powered parachute. Then if you made the boogie lighter you could go somewhere.

This is genius! Where is that desert?
