Instructables
In this Instructable you can see how to make a cool chopper/lowrider bike the cheapest way with some old bikes. Watch the bike down below, I just made it with two old bikes and some iron pipes.
I got the idea from another Instructable, watch the link below:

Step 1: What you need

Parts:

- At least two old bikes, one bike is also possible but gives your design lesser freedom.
- Bikes need to have two good wheels, the best is to have two different sizes. Notice: you should use a front and a rear wheel.
- Front fork
- Good working pedals
- Two bicycle chains
- Four meters of iron pipes
- Spraypaint
- Sheet iron
- Saddle
- Handlebars
- Keep the spare parts of the bikes, you could use them to finish your bike.

Tools:

- Welding materials
- Ironsaw
- Handtools
- Grindtool

Step 3: Saw the pieces you need

Now you can saw the right pieces you need from the frame and the front fork.
Saw with a iron saw and mark the place where you're going to saw.

Step 4: Try to fit the parts together and start welding.

Try to fit the frame parts together and measure it comparing your body.
Saw the pipes in the correct length.
Start welding the different parts together step by step.
Last welding job: extension of the front fork, use two iron pipes of the same length.
Watch out: Keep the frame straight and the wheels should be in line.

Step 6: Paintjob

Picture of Paintjob
Start by cleaning the bike carefully and take the bike apart.
Start painting with a spraycan of the color you like.
alot of work to get something you want

The bike looks good, but I hope you didn't trash the LeRun you got that seat off of.

Couple of bits of pedantry: Take the bike apart BEFORE cleaning it, as you'll have to clean where they've been, anyway. Also, why no sign of primer/undercoat? It does serve a purpose - Red Oxide slows rust, grey and white help your colour 'pop'.(the paint manufacturers will recommend one or the other for each colour, but experimentation can work well). Personally, I tend to use the Red Oxide first, then the grey, and finish with the white - the number of coats depending on how bright or rich I want my finish. And a clear (and, indeed, a not so clear) lacquer will protect you paint job,, as well as giving it more shine and depth. Anyway, those are picky things (probably because I haven't watched the video) - as others have said, "It's a chopper, therefore it's good". If I had them, you'd get FOUR thumbs up (and still I'd wish for more)!
The welding on the video was helpful. I may attempt this.

congratulations ! Nice and well done "teenager's bike" indeed but does not look very comfortable for the biker + lack of power (?). and what about aerodynamic when riding ?
Who the frick cares about aerodynamics and power! It's a chopper!
lilpep...and so on, Please consider the facts : driver is not in good position to push the pedals for acquiring some speed whithout getting soon tired and with the hands at eyes height he catch all the wind as if he was an "entonnoir". But, indeed, you are right, it's a chopper, even a Great " Wind Chopper" even if I found it fine and well done. Thank you for your comment.

nice ride.. when you refer to iron pipes, and sheet iron, i am presuming you mean steel?

I think so,mine has Lite Steel written on the handlebars

nice bike, might look better with a smaller front wheel i guess. ;)

it shouldn't be that hard to configure a set of brakes for the bike. just grab an old U-Brake caliper, measure and drill the holes and you should be fine. finding a cable may be a little difficult, so shop around and I would advise against having front brakes. because of the extra length on the bike, you would probably lose balance and the tail might kick out while braking. the brakes, and 8" rise bars, and it should be close to perfect

is the bike hard to steer? are chopper bikes sensitive?
That bike is Badass. I might try to get my friend to make it to compete with my chopper. Good Job

Thanks It was my first experience with a chopper bike so I was very pleased with it I'm glad you liked it.
bumpus6 years ago
that bike looks very well done, not like some of the hack-jobs done to bikes on instructables

Thanks for your comment.
Well I don't see you trying to make any cool bikes. I reckon most of the bike instructables are quite good. Don't criticise if you have no experience.
its just my opinion, and i favor this instructable over most of the others.
