welcome to the forum. I moved your thread to Alt Bikes from framebuilding, and hopefully some of the alt bikers can help you out

you're going to try and weld/build it up yourself? from scratch or mod something?

with a motor? because I've never done that and don't know about extra stresses.

truthfully I'm nobody's expert on it. I do the cut up freakbike thing. the easiest would probably be to mod/cut up a Schwinn occ chopper. I don't like how they steer though, no matter what you do with them (maybe lessen the rake, but I didn't try that). I don't have a completed rideable Schwinn chopper. I just couldn't get what I wanted out of them.

the better base bike to me, is the huffy jesse james wcc chopper. probably just as easy to mod, but maybe a little harder to find. I also think they're a little easier to ride unmodded as an adult (I'm 5'11"), but still pretty cramped.





here is one of two that I stretched of these with a stock wcc to compare. the other has the stock wheels on it. this one has a 26 front 24x3 rear tire. adding the rear took some extra cutting I don't think I'd deal with again. had a lot of chain interference too, so now it's a single speed again. you can see the stretch (the primered tubes). cut it in half and separate the front and back about 8.5". the tubes kind of all fall into place

style-wise, probably the easiest thing is to combine the two. start with a wcc and stretch it, then add the back section of an occ to get the 20x4 tire, and add the bottom bracket from the occ to space out the pedals/sprocket to match. if I ever do another that's what I plan to do (I think I'm building my last chopper right now though).

this is what I'm working on now



but like I said, I'm no expert. I've been fooling with it off and on for years and building as the idea comes to me. I also have no motor plans so I don't know how much more stress beyond pedaling it would take.

good evening my friend , first of all i want to thank you for your help, the problem is that in my country you can't find this type of bicycle so if i want to have a chopper bike i must build it from scratch this why i want to know the measurement to have a clear idea about the size of the bike

I would think that each bike is "unique".

Schwinn made a number of "chopper" bikes that are available around here, some are dirt cheap.

However, you can browse the internet for direct side views of bikes you like. Then import them into your favorite graphics program. The compare dimensions to known sizes such as wheels.

If you're going to be the intended rider, then you can use your arm reach and leg reach as some of the intended dimensions. Head tube angles can vary significantly.

Chromoly (4130) is a common frame building material, but you can also build with a cheaper high tensile steel.

Perhaps there would be two design approaches.

Bottom Up:
Browse around for good deals on parts available. Wheels, cranksets, & etc. Then design your bike around what you come up with.
Top Down:
Design your bike to your ideal specs. Then head out and find the parts you need to make it happen.
In reality, you'll probably do a bit of both. Figure out what is available as a target for your design. Otherwise you'll spend a fortune on new and custom parts.

Here in the USA, there are a few cheap fat tire bikes.

The Mongoose Massif can donate 20 x 4 1/4" tires.
The Mongoose Dolomite has 26" x 4" tires
Perhaps a few others too.

Front tires on choppers can be big or small, your choice for your design approach.

There are quite a few unique bike builds on Rat Rod Bikes

eh... back in my day... we just sawed whatever spare forks we had off at the crown and hammered them on to our bike forks. we didn't know nuthin' 'bout fancy geometries, weldin', safety, color co-ordinatin' or nuthin'.

Yup I had a chopper with forks that were from a scaffold hammered right over the original fork tubes.

There's about a free bike a week on Craigslist here. I was thinking of getting one and chopping that up to get the geometry for a chopper.

My dad did this when I was a kid with parts he found at the local dried up " Creek "/ unofficial dumping area.
If I remember right he actually put screws in it, but he sold it to a neighbor friend a long time ago.
It worked for sure but wasn't how I would choose to do it today.
If I was to do this I'd go with some kind of ratrod theme and make it appear as though it's supposed to look cobbled together from junk.

Ah yes, those truly were the days! Saw/chop, weld & paint. Voila! Custom bike!

I choppered a Murray Monterey one time, looked cool but the long rake gave it the turning radius of a battleship, also the coaster brake was not enough going down Seattle hills. If you make the rake too steep the front wheel will just kind of flop rather than turn...

That thing when you pull a wheelie and the front wheel and fork extensions roll off. Best thing was to jump off the back and start running.
We used to whack a set of 27" forks on a 20" frame. Did the trick and a bit safer.

Yup did this as a kid. There was a junkyard-ish place up the road and they always had chunks of galvinized pipe so we would cut off the dropouts from an old BMX fork, slide the tubes on, drill them for the axle and let gravity keep them on. Used to use a 12" scooter wheel for the front. Sketchy as heck but tons of fun.

If you want your chopper to be rideable, read up on rake, head angle and trail before you start cutting.

one of the mascots at the local bike coop.
