Hey, ever wanted the power to see peoples heads turn?,

get that hot girl of your dreams (the validity of this statement is unknown :P ),

or just want to look freakin cool?

Then you should invest in building your own chopper bicycle!

Its fun, not so easy, but still fun!

lets get started.


This instructable was based off of mountain lion chopper, but i will actually specify dimensions unlike the other one.

All thanks goes to Atomic Zombie!

*UPDATE*

Now that I have rode around town on this chopper eye candy, I realized what a great decision I made! The looks people give your are PRICELESS, and a couple of times people actually got out of their cars to take a picture. Trust me, this chopper beats riding on the crap 30$ murray mountain bike it was before!

Don't wait, you can pimp out your ride too! just follow the instructions!

Step 1: Get an old mountain bike

If you have a Murray mountain bike, this works best, but any old mountain bike will do.

This is exactly what the bike i used looked like.

yo husamwadi,
am a pre teen and i want one of these, but what do i do
if i get ant taller i'll out grow it really quick (i'm really tall)
or should i mak it and make mods when i get taller

pretty pretty please with extra ice cream, hot fudge, and rainbow sprinkles on top !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
husamwadi (author) in reply to awesomevampireAug 5, 2011. 11:30 AM
listen....there's no such thing as "too tall" for anything.....

If you mod a 26in bike using my methods and measurements, there is NO WAY you could out grow the bike, unless your dad happens to be big foot.

so go ahead and do whatever whenever- with your sprinkles and rainbow pony pickles.

p.s: don't hack your sister's account, unless you like a hand print across your face; take it from a guy with experience.

Funny thing... I'm 6'8" and basically all standard frames are far to short. I'm planning on adding a small frame section to the bottom that pushes the pedals further towards the front tire and creates more leg room.

you do that wooly mammoth. :)

cool chopper dude, enjoy it!!
kavo says: Jun 7, 2011. 7:24 AM
why do you have to modify the frame?
husamwadi (author) in reply to kavoJun 8, 2011. 9:00 AM
If you dont change the angle of the goosneck, and extend the frame, you will make an akward/unstable bike which is impossible to drive.

i see a snapped headtube in your future, good job anyways!
husamwadi (author) in reply to struckbyanarrowMay 30, 2011. 7:01 PM
yep, i hear some creaking...... :P
mikeasaurus says: May 23, 2011. 9:34 PM
Nice rake!
I've seen signs of bike with rake's similar to this fracturing near the head due to stress of the front wheel being so far out, is there a threshold calculation based on frame thickness/rake degree or is just a prototype? Other bikes I've seen have adopted a tension cable from front hub to frame which you may consider.
Either way, the bike looks great!
husamwadi (author) in reply to mikeasaurusMay 23, 2011. 10:35 PM
You should show me this "tension thing", actually this is the first time I have ever made anything from my own, let alone complete it :)

I don't know how long the forks will hold, they are really sturdy though. My rule of thumb is "The First pothole's gunna be the Last pothole :P"
mikeasaurus in reply to husamwadiMay 24, 2011. 10:32 PM
Here's an example of a tension string placement. From what I've seen the tension is held by steel wire with a thickness of about 10mm, from the from wheel hub to somewhere on the frame. I think this would only be necessary with bike with a wide rake, but there's probably a calculated 'sweet spot' where you can maximize the rake without a tension string.

Whatever, this is a homebrew project and there is no need to over-think it. Have fun, break your bike, rebuild it better than before. Be safe and have fun. Keep building those 'choppers!

Thanks, I will consider it.

my current problem right now is that the front wheel is so old that the spokes lost their tension; aka the wheel is warped and about to taco.

I need to find a new wheel :P

Atomic Zombie may have some advice on this 'threshhold calculation' issue. I just bought his book "Atomic Zombie's Bicycle Builder's Bonanza ", and there's a huge section in there about building choppers.

Sweet bike, bro. Once I'm able to afford a welding rig and learn the basics, this looks like something fun to try!
