okay. there is hardly any resources on how to make motorbikes.

how the fuck do I build this?

Why would you waste so much time on a moped?

That's a modified moped. There are plenty of resources on modifying 2-stroke low displacement mopeds.
Bore kits, exhaust, carburetors, spark gap, variator weights, sprockets, and so on.
There's a great deal you can tweak on them to make them faster. Not so much you can do to make them more reliable though.

There are some forums for specific popular brands (Like Tomos and Puch) and more overall boards like Moped Army (which has a horrible layout).

>that seat
nigger what the fuck are you doing
in all honesty though, that is a motorized bicycle that's been modified, no joke. I've built a few and they are cool, but if you want a full motorbike you should go all out and build an indian or a bobber. It might even be easier since you don't have to compact everything together. Frames are expensive though so buying a secondhand fixer-upper might be you best option to get a blend of diy, affordability, and coolness.

The only things you're really going to physically make yourself on a motorbike, in regard to functionality, is the frame, handlebars and maybe a few cosmetic items. Everything else you'll have to source new or from a wrecked bike.

Realistically you're not going to make your own forks, engine,braking system etc. I mean, if you watch shows like American Chopper, they're pros with a shop full of machine tools and even they order in most of their stuff.

I had a series of videos I downloaded from Demonoid on frame construction for a chopper. They were pretty good. I assume they'd still be available somewhere on the internet.

You'll need to become proficient in welding and tube bending.

[Anonymous No.325669]

I would seriously pay someone to make this for me.

[Anonymous No.325725]

Okay. So i'm getting a 4stroke engine, I have a decent frame, disc brakes, etc

If anyones experienced, all I can't find is the headlight(probably custom honestly) and the wheels/tires.

If what you're building is actually custom and not just a collection of aftermarket kits, it takes a great deal of tools, time, and know-how to make one-off motorcycle or Moped.

Pic related is the one-off "Go-kart motorcycle" I made this summer.
Customized mopeds are much easier because of the wide variety of aftermarket parts available.

>>HOWW???
I'm a CAD/CAM tech and protyping specialist at a small company that has a machine shop. So everything involved is stuff I do most of my working hours (except welding which I only have a couple months of practice at).

Short version is I have a dirt bike frame, bought a lawn mower engine and a Go-Kart CVT, then made a motor-mount for it, and added a bunch of other stuff to get it working the way I wanted it to.

[Anonymous No.326650]

Customized motorcycles are not something you should buy or build to some other person's plans. They are a highly personalized exercise in creativity, aesthetics and craftsmanship.
Buy the best bare canvas you can afford and impress us with your own masterpiece.

About how much did it cost to build the whole thing, how many hours you put into it, and did you use any tuts?

I'm basically making a moped. I'm trying to make it at least go 40 or 45(For emergency maneuvers, I'll be cruising at 35 maybe)

My original plan was to get a bike motor and go from there

[Anonymous No.326660]

>>326654
>About how much did it cost to build the whole thing
$700 excluding the frame, which I've had for a couple years. But don't take that figure as a ballpark because I got a fair number of the parts really cheaply.
>how many hours you put into it
1 or 2 months worth of free time. I had it running fairly quickly but there's always a long teething process involved in making something like this where you have to weed out and solve technical problems.
The CVT came with the wrong size belt and it took quite a while for me to find out. The chain tensioner went through a number of revisions before it wasn't causing wear on the chain. The electrical system was a little challenging to get it working the way I wanted. And I had plenty of issues with cheap parts like turn signals crapping out quickly.
>did you use any tuts?
I did some reading on Go-Kart power trains and I have experience modifying mopeds. I also used several gear ratio calculators and tire/rim size charts.
But there's just not going to be anything like a "how-to" for this sort of thing.

Is correct.

My Tomos A35 will hit 50 on flats. It has a DMP kit, Biturbo exhaust, upgraded gearing.

Total cost, 700 including the bike.

I have plenty of pics, and I've posted all of them here before.

Other than the price (which will vary greatly depending on where you live and what you can find) this might be your best option.

If you want electric start look at I think all the A55 models (Streetmate, Targa, or LX) have one included.

I had a streetmate a couple years ago. Rode it year-round. Made my feet fall asleep fairly often.

Umm, pretty sure A55 models are still pedal-start.

You can pedal-start them, but some models include a starter motor and switch as standard.
My streetmate had electric start. I'm not sure which of the other A55 models include one.

>CAD/CAM

CAD rarely solves involved in making one-off objects (except sometimes fabricating intricate parts, usually just for aesthetic purposes).

rule of thumb: if you cannot solve a mechanical design problem with pencil and paper and your head, a computer will not help you.

fantastic work is done with ordinary tools, yes, even or especially in the 21st century. no luddite here -- just pointing out that running to complex tools isnt problem solving, its problem-creating.

Duh. And I was only listing my job title.
CAD is best used as just a paper substitute. It's not going to do any of your thinking for you.

[Anonymous No.327221]

If you wanna make a thing like that on the cheap I suggest you go out and buy a second hand bike and a 50cc engine (like off a pocket rocket) off ebay. Then put them together.
or if you wanna know how they work buy a small bike (ct110 or something) that is in disrepair and fix it up.
I went for the second option and bought a larger bike that's really rare outside japan and worked on that. I'd really recommend either option.
