Coming along nicely...

In addition to everything already said in this thread (which I agree with), noone has yet mentioned that this thing has no brakes.

You've asked for criticism - here's some. This thing is a rolling death wish. There's so many ways things can go wrong here, and hurt not just yourself, but someone else around. If you insist on riding this (which is a really, really bad idea), at least make sure you won't be doing it near other people. If you want a Darwin award, it looks like a surefire way, but it would really suck if some innocent bystander got hurt.
 
That frame appears to be aluminum,and normally frames constructed from it are heat treated after welding to increase strength. This would be imperative for a powerful "e" system IMO.

A potential thief who knows about e-bikes might take a fancy to the battery and take a box cutter and remove it and walk away with it.

👍 good point!

Note to self: Never buy a duct taped battery at the flea market. Could be stolen. Now that they’ve made <$1000 of shoplifting illegal here again, thieves may “steal” from more places than the drugstores, big box stores, groceries or Home Depot.

Cleaned up the wiring finally. Shortened, heat shrinked, conduit, even found an off brand ignition switch at the thrift shop

It's wedged in that iron strap cradle pretty good. The chicken wire is mainly for show. Not to say it isnt a possibility though I will admit. Any suggestions as to how to make it more secure? Besides buying an ebike with a lockable battery

Your creation is looking much better than in the first picture. Is the bike frame aluminum or steel?
Yes to brakes! I'd say finish it up and ride it. Afterall:
Vaya con dios.

It's steel, currently looking for a hub with a disc to swap over to this wheel for the front. As for the back brakes, still pondering that one. No room to mount pinch brakes, nowhere to mount the clamp style. Caliper is... Maybe possible. I'd have to use the saw blade as a disc but I doubt that it's true
 
Okay okay let's say I properly rewelded every seam and crack, and put new quality brakes on it. Would it be good then? Or would it still be considered suicide with more steps. Cuz don't think I don't appreciate all this shit talk, y'all's opinions matter to me and I know y'all have good intentions that's why I asked for the criticism in the first place
 
Rewelding every seam and crack would take more time, effort and ultimately cost than getting a new (used) frame - especially since this one appears to be a folder, which would be even less trustworthy. You have components that look usable, so in order of importance:

* New more trustworthy frame
* Brakes on both (not optional) wheels
* A rigid, splash/dustproof battery enclosure solidly mounted to the bike

Would immediately make it a much more sensible proposition. I know that you've put a lot of effort in that frame, but as others have said, you have likely severely compromised the structure. Starting off with a traditional hard tail with a large triangle to fit your battery would be that much easier. Since you have what appears to be quite a strong motor and pedaling seems very much optional, maybe you could find something like an old moped with a busted engine and move it all over. That could have all the components needed...

If you know we have good intentions, you should realize it's not shittalk. I really do not think your choice of frame, and mods done to it, look good for your intended purpose.

Bananu7 made some excellent suggestions I would follow. And, if you post each step here, like looking for suitable frames, I'm convinced you will get a lot of people trying to help you along, it's just that people don't feel comfortable helping you with this build because they fear they might feel guilty if something happened to you while riding, at least that's my interpretation.

It's all done from a good place, no bad intentions.
 
Ok duely noted everyone I am aware of the risks involved and I will be making improvements as I am able. At the moment I need someway to get the from place to place within a short radius. This product is a culmination of whatever I have had lying around. Surely I hope people don't think I wanted it to look like this. I know I started with shit and I know what it is. I'm just trying to make it into the best shit I can with what I have at my disposal. I know very well the danger I've only rode it for a half block at a time when I take it out. I think it'll go much faster yes, but I'm taking it slow. This is if anything a learning experience for me also looking back at the original pictures.

To paraphrase: I don't plan on passing this down to my kids but I do plan on it becoming an option

Some wire ties, shoelaces, or some thing to tie wires so they not flopping around.

Chain gear behind seat? Bicycles can be dangerous. Dangerous + chain gear = more dangerous.

Red painted chain = Beautiful from a artistic point of view.

Red painted chain = Bad for mechanical reasons.

Motor oil is good on chains. Make sure links are not painted stuck. Wiggle every link.

Happy to see a seat. I was having trouble comprehending how to stop with no brakes if there was no seat. Trying to put feet down to stop with no seat could be problematic.

What happened to the place image inline button?

Hey there everyone been riding ebikes for about a year now been riding and building motorcycles and motorbikes for over a decade this is my first homebrew ebike build. 72v 3000w Amazon motor. Homemade (if that's not obvious) 72v battery just took it on its first ride today. Not far just a block. Besides just showing off I was wondering if anybody out there would be so kind as to criticize my work maybe some tips from people who know more than I do. And yes I am aware it has only one pedal. Thanks all
