Introduction: Atomic Zombie's Carnage Chopper Bicycle

Picture of Atomic Zombie's Carnage Chopper Bicycle

Full suspension mountain bikes with v-shaped frames have become very popular over the years, so it's no wonder that the local landfill has been seeing more and more of the cheap steel versions lately. The typical lifespan of a department store type bike seems to be about three years. Although fully suspended, the inexpensive steel versions have no more quality about them than their non suspended counterparts, and this makes them great for chopping and welding. A full suspension chopper? Nah, what's the point? Of course, the unique qualities of the v-shaped frame were quite appealing.

I came across the idea for this chopper by accident one day when I was moving the giant pile of scrap bike frames from one end of my small garage to the other. This regular ritual involves throwing one frame after the other across a 10 foot distance until the pile was at the other end of the garage. As I tossed this full suspension frame onto the pile, it landed upside down with the rear triangle extended outwards as far as it could travel and voila! An idea came to me as you will soon see as you read on.

Step 1: Find a Donor Bike

Picture of Find a Donor Bike

The donor bike has a single spring connected to the rear triangle which is hinged just behind the bottom bracket (Photo 1). The frame consists of two nicely curved oblong tubes shaped like a wishbone; this could easily be transformed into a cool chopper with loads of style. The condition of the suspension is not important, in fact, you do not even need the spring for this conversion. Same principle for the front fork suspension as well. This bike was found at our local landfill, and is pretty much shot - no cables, shifters, brakes, and the front suspension was floppy - a perfect candidate for chopping!

Step 2: Take It Apart

Picture of Take It Apart

I stripped down the entire bike (Photo 2), and found the front rim to be rusted and seized, so it was tossed. The rear wheel had an "old school" chrome rim and sidewall tire, which was good, since I had a matching wheel in a smaller 20-inch size. I always like the smaller front wheel on a chopper, so this turned out ok. As for style, I though a really long, slender look would look great with the cool curves of the oblong frame tubing. The first step was to forge out the basic frame, then see were my twisted imagination took me.

Step 3: Hack the Frame

Picture of Hack the Frame

It wasn't at all difficult to make a stylish chopper frame out of the mountain bike frame - in fact, the entire frame only needed a single cut and two welds! As you can see in Photo 3 above, the little seat tube stub was cut from the end of the frame, and a section of another mountain bike (bottom bracket and down tube) was laid in place were the suspension spring used to be. Not only does this create a low stretched frame, but it places the head tube on a perfect angle for some seriously long forks.

The bottom bracket and length of down tube can be cut from any old frame - I chose one with oversized tubing in order to keep the fat tube look. Notice how the end of the tube (opposite the bottom bracket) has been hammered somewhat flat so that it can be welded to the frame more easily.

Step 4: Weld the Frame

Picture of Weld the Frame

Because this new bottom bracket was the non threaded type for a one-piece crank arm, I did not have to worry about orientation (no threads), I just put it in place then welded it solid (Photo 4). Even though the rear of the frame is still hinged, the addition of his new tube makes it as solid as if it were welded at every joint. The length of the added tube and the position of the rear triangle prior to welding will determine the rake and height of the frame. For my frame, I wanted the chain stays (which are now on the top) to run parallel with the backbone of the frame.

You will notice that the rear dropouts are now reversed. They could be cut and re-welded, but I left them, as this added some danger and weirdness to the bike. Better make sure those rear wheel nuts are tight, buddy!

Step 5: Separate the Forks

Picture of Separate the Forks

Here are the front suspension forks taken apart (Photo 5). There is a long bolt that has to be removed under the plastic cap on each top end of the fork legs. Once the bolt is taken out, the forks just fall apart. Not much of a spring in each leg; it's no wonder why the suspension felt so weak. Toss the springs on your junk pile for some other evil contraption, as they will not be needed for this fork extension.

You may want to leave the horseshoe shaped bit of steel that joins the two lower fork legs together. This piece adds strength to the fork and prevents twisting. It may also help in aligning the extension when it is built, or be a great headlight, fender, or human skull mounting plate. I hated the look of this thing, so I promptly hacked it off, but it's your decision.

Step 6: Fork Extension

Picture of Fork Extension

To extend the forks, I found a pair of 50-inch long lengths of 1.25-inch electrical conduit, and wouldn't you know, it fit snugly over the end of the lower fork legs (Photo 6). Because of this, alignment of the fork legs to the extension tube would be a "no brainer", just put them in place and weld. Since the front forks were to be longer than 4 feet, 1.25 inch conduit was just right. One-inch conduit would be a little too flexible for my taste. Muffler tubing would also work for this.

Step 7: Weld the Fork Extensions

Picture of Weld the Fork Extensions

Getting here was easy, just drop the fork leg into the conduit, and weld it solid. I took this opportunity to fully weld and grind the joint, as it would be much harder to do once the forks were completed. Photo 7 shows the welded fork legs.

Step 8: Join the Fork Stem

Picture of Join the Fork Stem

The fork stem would be fairly easy to join to the fork leg extension tubes since it had a square tube originally connecting the stem to the fork legs (Photo 8). By cutting the original top legs from this square tube as close to the joint as possible, it would be easy to weld the new fork extension legs in place. Once cut, the area was ground slightly to clean up the mess and restore the round profile needed to make a good fit with the conduit.

Step 9: Connect the Fork Stem

Picture of Connect the Fork Stem

To connect the stem to the fork tubing, I measured from the top of each leg, and marked a point that would place all three tubes at the same height (Photo 9). As you will see later on, because of the traditional triple tree design, the fork stem and both fork legs needed to be at the same height.

I also had a front wheel bolted to the fork dropouts and then laid the entire unit on a flat board to aid in alignment. The distance between the top of the fork legs is almost exactly the same as the distance between the lower fork legs or dropouts, about 5.5 inches. You could make the distance between the top of the fork legs whatever you want, but I think it looks best if they are roughly parallel all the way up the bike.

Step 10: Check Fork Alignment

Picture of Check Fork Alignment

Once it was tack welded solidly, I checked the entire fork for alignment by looking down the length while the front wheel was installed (Photo 10). If all checks out, then apply the final welds to the fork stem and fork legs, if not, you know what to do (chop, chop).

If there is only a slight misalignment between the legs, you may be able to just twist the fork while holding the wheel solid to put it back straight. If the entire thing looks like it was thrown off a bridge, then break those task welds and try again.

Step 11: Cut the Gooseneck

Picture of Cut the Gooseneck

The top of the triple tree fork design will be a flat plate bolted to each fork leg and secured to the fork stem via gooseneck stem. Simply cut the top section from an old steel gooseneck so that at least 2 inches of the stem (tube with the angle cut at the bottom) remains as shown in Photo 11. You will not need the bolt and wedge, or the clamp part of the gooseneck.

Step 12: Triple Tree Fork Plate

Picture of Triple Tree Fork Plate

The top of the triple tree fork is just a bit of plate or flat bar rounded at the edges to conform to the width of the fork legs (Photo 12). A hole is drilled at each end to approximately the center of each fork leg, or to allow a bolt to pass through the plate and meet a nut welded into each fork leg as will be shown in the next photo. You may want to weld the two nuts in place first, coming back to drill the holes in the plate later, just in case the two nuts are offset in the fork legs as the ones I used were.

If you really wanted the holes centered on the plate, the nuts would either have to be large enough to fit snugly in the fork tubing, or a washer would have to be welded in first, then the nuts into its center hole. The method I used here (using half inch nuts and bolts) works just fine, and is plenty strong for this design.

Step 13: Weld Nuts Into the Forks

Picture of Weld Nuts Into the Forks

Photo 13 shows the 1/2 inch nuts welded into the fork legs. Since the diameter of the nuts is much smaller than the inside diameter of the fork tubing, they are only welded along one side. This method offers plenty of strength. The nuts should be flush with the top of the fork tubing, and end up as much in the center as possible. The holes in the triple tree top plate are drilled to match the location of the nut centers.

Step 14: Completed Triple Tree Forks

Picture of Completed Triple Tree Forks

Here are the completed triple tree forks installed on the bike (Photo 14). Notice how the top plate is rounded around the edge of the fork legs. This gives the bike a professional look. The nice thing about this triple tree design is that it does not restrict you on what type of handle bars or gooseneck you have to use. The top of the plate is blank, and you could weld the clamp form the butchered gooseneck back to the top for a standard set of handlebars, or go for something more radical like I plan to do as you will soon see.

Step 15: Spoke Accessories

Picture of Spoke Accessories

Since the top of my workbench was clean (rare event), I decided to get out the jigsaw, some scrap steel and work on some eye candy for the bike. Photo 15 shows a cool looking evil spike thing I cut from some paper to install on the rear dropouts (drop-ins on this bike). I like to work with paper and scissor for this kind of thing, as it is easy to make adjustments then trace the design onto the desired material.

Step 16: Making Designs From Steel

Picture of Making Designs From Steel

12 gauge steel is light, easy to find, and can be readily cut with a grinder or jigsaw with a steel blade. I use this stuff for most fenders, gussets and eye candy work. I traced the shapes outline on the steel using a black marker (Photo 16) so it could be cut.

Step 17: Cut Steel Shapes With Jigsaw

Picture of Cut Steel Shapes With Jigsaw

The shapes are cut from the steel using a jigsaw with a steel cutting blade (Photo 17). Take your time, especially around sharp corners and your blade will last a long time. This blade is quite a few years old. If you have to start cutting in the middle of the plate, drill a 1/4 inch hole just outside the cutting line to get the blade in.

Step 18: Weld Cutouts to Dropouts

Picture of Weld Cutouts to Dropouts

The newly cut spike shapes are welded to the tops of the rear dropouts (Photo 18). A few tack welds were done first, so I could bang the steel into the correct position, then it is fully welded and ground clean. Those things are sharp!

Step 19: Start Making the Fender

Picture of Start Making the Fender

Since the jigsaw and sheet metal were already laying on the workbench, I decided to make a custom rear fender using the same method as the dropout spikes. I cut two sides and a center strip out of the steel (Photo 19), and they will be welded together to form a fender. The center strip is longer than the side parts because it has to fit around the curve. Those boring formulas you learn in math class do actually come in handy some day!

Step 20: Tack Weld the Fender

Picture of Tack Weld the Fender

To make the center strip conform to the curve on the fender, it is first tack welded to the end, then bent along the curve, placing tack welds at about every half inch (Photo 20). Just keep tack welding and bending until the entire length is completed.

Step 21: Check Fender Curve

Picture of Check Fender Curve

Once you are done tack welding and bending the center strip, it should for a perfect curve along the top of the fender (Photo 21). At this point it is easy to manipulate the sides to ensure the entire fender is aligned properly.

Step 22: Weld the Entire Fender

Picture of Weld the Entire Fender

To ensure that your fender will be solid, and for that professional look, the entire length of the joint on both sides of the center strip should be welded (Photo 22). It's best to weld with the amperage a little low, even though the weld will be chunky. We are going to grind it all away anyhow. Do a bit of extra grinder work, rather than fill in a burn through on this part of the build. Do not weld inside the fender, or it will warp out of the sides.

Step 23: Grind the Fender

Picture of Grind the Fender

If you have some patience, the finished fender will look factory pressed after you grind the welds (Photo 23). I always do the rough grinding with a heavy disc, taking the weld area almost flush with the metal, then I switch to a cut off disk for the fine work. Once the fine work is done (this includes re-welding pits and holes), I use a sander disk to clean it right up.

Welding the small missed areas and pin holes usually takes two or three tries to get right, so have patience and you will be able to make a perfect fender. Your grinder is your best friend when doing this kind of work.

Step 24: Weld Fender to Seat Stays

Picture of Weld Fender to Seat Stays

The fender was welded in place just inside the seat stays in order to hide the welds (Photo 24). Three short welds per side are plenty to hold the fender in place, and I would avoid welding the entire length or you may end up warping the frame, fender or both. It's best to weld the fender in place with a wheel installed, so you can make sure nothing rubs.

Step 25: The Steering Wheel?!

Picture of The Steering Wheel?!

Yes, it's an old skool racing steering wheel (Photo 25). When I was a kid, I always wanted to build a chopper with a steering wheel, but always got caught trying to take the one from the family car, so now was my chance. Will this even work, you ask? Why not? You hold on, you turn - what's the difference if it's a bicycle handle bar, steering wheel, or axe handle? None, just as long as you can turn the forks.

Since the top of the triple tree plate was blank, all the was needed is two bolts welded to the top that would hold the steering wheel. I found some old wheel stud bolts that would fit the holes in the steering wheel just fine.

Step 26: Install the Steering Wheel

Picture of Install the Steering Wheel

I placed the bolts tightly on the steering wheel, held it in the proper place, then tack welded the bolt heads to the top of the triple tree plate (Photo 26). The steering wheel was then removed and the bolds were welded all the way around and then ground clean. Putting a steering wheel on a chopper was not that hard to do after all!

Step 27: Make Seat Supports

Picture of Make Seat Supports

The seat was made by cutting to sides from the left over sheet metal (Photo 27) using the jigsaw. These were bolted to a plywood base so that is fit snugly over the original bottom bracket - which was on the top of the frame.

Step 28: Make the Seat Base

Picture of Make the Seat Base

The seat base is cut from 3/4 inch plywood and placed directly on the frame and fender (Photo 28). The two steel sides cut earlier hold the seat snugly between the retired bottom bracket, no bolts are necessary. As for padding, I plan to glue some rigid black foam directly to the plywood and leave it as is - no vinyl. Rigid black foam looks fine with no covering, and is very resistant to wear and moisture.

Step 29: Put It All Together

Picture of Put It All Together

I threw the bike together to make sure all the components fit and had proper clearance (Photo 29). Everything looked just right, and the steering wheel gave the bike a unique look indeed - a cross between a car and chopper, hence the name Carnage. I chose a minimalist front chaining and crank set from am old BMX, and then cut the chain to fit on the mid rear cluster gear. I resisted the urge to test ride the bike, I wanted to take it out fully painted for the first time.

Step 30: The Seat

Picture of The Seat

Here is the completed seat (Photo 30), including the rigid foam and painted sides. Because the seat just drops over the top of the frame with plenty of extra room underneath, it is a good place to hide things - but try to avoid border crossings with contra-ban under your seat!

Step 31: Suicide Brake

Picture of Suicide Brake

In line with the car-chopper fusion theme, I installed the brake lever as though it was a stick shifter. On a motorcycle, this kind of installation is called a "suicide shift", since you have to take your hand of the steering to us it. Kind of ironic that this is also the brake, don't you think? As shown in Photo 31, a small stub of tubing from a handle bar is welded to the frame so the lever can bolt on to it.

Step 32: Priming

Picture of Priming

The next few photos show you how to get a decent look from a spray can without having a proper area to paint. I hung the frame from the clothesline in the backyard with a bit of rope (Photo 32). Try to get the frame hanging in the center of your yard if possible, and move anything important at least 10 feet away from where you are painting. Windless, bug-free nights are best if you have such a thing in your area.

First, I take a can of metal primer, shake it vigorously, then just apply a light dusting using quick strokes at about 10 inches from the frame. Do not spray directly at the same spot. Always do it in strokes. The first coat of primer should look like it does in the photo, just a very light dusting, no more. Let it dry for 15 minutes.

Step 33: More Primer

Picture of More Primer

Once the first light dusting coat of primer is dry, you can fully coat the frame with primer (Photo 33). Again, shake the can often, and only make short back and forth stokes with the can held at least 10 inches from the frame. This will take a while and may use more than one can of primer, but will result in a run-free well coated finish. To get to this stage, I used the entire can of primer. Be sure to get the entire frame from all angles - lay on the ground if you have to.

This coat of primer should set for about an hour. How does your lawn look now?

Step 34: Painting

Picture of Painting

Once your primer has dried, and if the neighbors have not called the cops on you for stinking up the neighborhood, you can now start painting the frame. The first coat of paint should be done like the first coat of primer, just a light brushing of paint, not worrying about all the blotches or missing spots (Photo 34). The idea is to just dust the frame so the next coat will take.

Let this first paint coat sit for about half an hour or so. If the sun is out, it will dry even faster. If it rains, you're screwed!

Step 35: Final Painting

Picture of Final Painting

Now you can fully paint the frame, using the same side to side strokes with the can held away from the frame. Shake the can often, and do not spray the same area over and over. Keep moving around the bike, dusting the frame until the actual color starts to become uniform and solid (Photo 35). You will probably need 1 full can of spray for a frame this size. If you take your time, moving around the frame at all times, the final paint will be a smooth, run free coat.

Although the paint will not be nearly as scratch resistant as a professionally done powder coat, it should look just as good.

Step 36: Looking Good!

Picture of Looking Good!

The painted and assembled bike is sleek looking unique chopper / muscle car fusion. (Photo 36). A huge light was added to the top of the forks, and the frame was painted black at the tips of the forks, dropouts and head tube. The suicide brake lever was connected to a side pull brake, hidden under the rear of the frame, and it does indeed work.

Step 37: Different, But Cool

Picture of Different, But Cool

The steering wheel and upright brake lever give the chopper a surreal look (Photo 37). I think it all came together nicely. It's hard to tell this frame is nothing more than a slightly modified suspension mountain bike!

Step 38: Checking It Out Some More

Picture of Checking It Out Some More

The bike is long, and low (Photo 38). The overall seating position ended up being very comfortable, and could accommodate riders of varying heights easily. For more adjustability, the bottom bracket could be made to slide forward for riders with much longer legs.

Step 39: The Finished Rear End

Picture of The Finished Rear End

Photo 39 shows the rear details of the bike - seat, fender, and brake.

Step 40: Add Some Pizzazz

Picture of Add Some Pizzazz

The frame is purple and black with white stickers on each side (Photo 40). I'm not sure what the huge dual colored light is from (possibly a railway crossing?), but it looks cool on the bike anyhow.

Step 41: Cool Rider on a Cool New Chopper

Picture of Cool Rider on a Cool New Chopper

Nothing odd about riding Carnage - in fact, the steering wheel feels just like a handlebar (Photo 41). The crazy brake lever on the other hand, is definitely an acquired taste - install at own risk!

Step 42: Easy Rider Ready for the Road

Picture of Easy Rider Ready for the Road

Well, there you have it, another unwanted bicycle rescued from the scrap heap and churned into a unique and rebellious ride! With only a few welds, and a handful of steel, Carnage (Photo 42) was born. What will your imagination bring to life?

Im definitely going to build this thing.... I have a pretty nice mongoose, but I hucked it off too big a ledge when I was at a local mountain last summer, and ruined the suspension! Its all stripped, and shot... It would cost more to get it fixed than buy a new one.... (of the same type (my uncle owns a bike shop. (bikes=free labor=expensive))) But he lives in colorado..... Im from NY.

Looks nice

Hey man, Nice bike and tutorial. I looked over all your work you posted here and was just curious. Is there any way you can make a real cool chopper (similar to this) in a trycicle form with the back so someone could stand on it or with a side car? I'm just thinking it would be cool if (without making it look stupid) if you could have a 2nd person on the bike. I have always been a fan of sidecars and trycicles.

hi. My name is JR Wilson, and i'm living in thailand at the moment. i'm 14 years old, and have quite a wide range of experience with motorcycles. i've been racing since i was 7, and currently i have a honda CB 400. its pretty sweet. well, i got interested in chopper bicycles a few months ago, and i think it would be cool to build one. i like the stuff you do. its some really good stuff. i wanted to know if you could help me find a design for a chopper bicycle. i kinda want it to be long, as well as tall, but i want a laid back riding position. i dont know what sort of a thing i should do. i saw your mountain lion bike, and i really liked what you did. i just didnt like the akward riding position. if you know of the blue chopper that Robert Lalonde made, i think that would be nice. but difficult to make. i need to find the right way to build the frame. i like the second one as well, but i just cant figure out how to make it. i was wondering if you could help with an idea? i have a guy down the street that can do the cutting and welding....i like your work!

butthead95 (author)wilsonjames2008-07-08

make the back tire 8" smaller than the front. you might want a banana seat tilted back real far. and finally extended handlebars at a 35-40 degree angle. my cousin and i are 13 and do stuff like this but no frame xtension bcuz we dont have the sources

This is great bike and I love riding mine I just completed mine but it appears others think its cool too cause after to weeks it was stolen last night >< so make sure its locked up ALOT cause there are talantless people that cant build their own that steal other peoples creations

paappraiser (author)2007-06-21

are you stick welding ? Ive been looking to do some fun bike project like this and want to pick up a cheap welder and cant decide on stick or gassles mig. Suggestions on a cheeepie?

cvxdes (author)paappraiser2008-01-23

Gas isn't that expensive, and it's definitely better than flux core in my opinion. It's worth your time to just use gas, if you do mig welding. If you're doing arc though, I don't see how you can go wrong with a "cheap" machine. As long as it works, there isn't much that CAN go wrong with an arc welder

Cam F (author)paappraiser2007-06-21

I suggest NOT buying a "cheepie"-think of is as and investment in all your future projects

8thDay (author)2008-01-17

What kind of welder did you use and what were the settings and type of wire or rod used Thanks. P.s. the trike rocks

KoolKat (author)8thDay2008-01-23

I have welded much thinner than .035 using my AC setup, and without a doubt MIG, TIG, even DC would make the job much easier. When I started doing this, I made a decision to never use anything else in my shop but an angle grinder AC welder and the most basic tools. My welder actually has a DC setting, but I always leave it on AC and only use 6013 rods - 3/32 for almost everything, and 1/16 for steel as thin as bike fenders. I only do this so that anyone can do what I do without spending a lot of money on tools. But without a doubt MIG, TIG, etc are the logical progression as you become more skilled and need to work with aluminum or exotic alloys. Chromo is no problem with AC, though. I guess I do get a twisted bit of satisfaction when I show a welder some of the complex robot body parts made from 1/32 steel, and try to convince them that I welded all the edges with 3/32 6013 ac rod. I do have some advice for those just starting to weld with stick – cover up, or remove the Amperage settings on your welder, and adjust it by feel. 45 amps may be good one day, but 2 hours later, you may be doing the same weld at 60 amps. Be one with the machine, forget about the numbers on the dial. Stubborn forever, Brad

8thDay (author)KoolKat2008-01-23

awesome reply especially about the feel of the welder. I suck at brazing and I was trying to decide between a wire feed or stick welder and will mostly want to work with bikes I have used a Hobart Handler 125 in the past just wire no gas and did not know if it would work. thanks again and keep up the sweet rides

AAAH! I remember as a kid in the late 60's early 70's - when Easy Rider came out. We all mangled our bikes to try and produce choppers. Or course, some were better then most. Great job, that's a wild bike - now if I were about 35 years younger. Thanks Duane E Smith

Do you do this for a living? Do you sell these choppers?

Unfortunately, we don't sell the completed bikes. We do sell the plans so you can build your own. Tons of pictures and step-by-step instructions. The goal is to help anyone design and build their own custom creation, instead of "cookie cutter" factory products. Dare to be Different!
