Bent frame- Is it toast? Could it be safe ride?
Hey all- first time poster here.
Bad accident today has bent my frame slightly, see the pic. Is it toast? Could it be safe to ride? I havent bought a new wheel to try it out on yet (as you might guess the old wheel is out of commission now!) but thought maybe I could get some advice on whether I'm gonna need a new frame now....
thanks.

There are tools that will straighten that kind of bend. Basically a two long pipes. One goes through the top tube; the other is a spreader that braces against the bottom bracket.
Not enough of an expert to comment on the absolute wisdom of your bend, but the tubes have collapsed and I am skeptical about both the possibility and wisdom of a repair.

Yes, all of those, and you'll be lucky if the front wheel clears the pedals, let alone your feet. It's gone, be grateful you are doing well enough to post the picture and type.

The frame is scrap. Not reasonably repairable. Get a new bike. Period.

I'll add fuel to the toaster. Give it a decent funeral and replace it RIGHT NOW.

haha, thanks everyone, i think i get the message 
for those interested, i was going down hill (in a bike lane) and crossed an intersection and a car tried to drive across me (turning left across the street) and i had the choice of slamming into its bonnet or veering into oncoming traffic. i chose the former. i'm just bruised luckily, might have cracked a rib at the worst.

I'm usually the guy that says stuff is OK to ride, but this is well beyond that.
Not only is it toast, it's badly burnt toast, far beyond anything you'd butter and eat.
In any case there's no reason to even consider whether it's safe. I'll bet that if/when you stick a wheel into the fork, it'll jam against the down tube.

Not only is the frame way beyond done, but I bet the fork is done. Stick a fork in that bike, it is way beyond saving other than maybe some parts from the rear of the bike.
Just out of curiosity do you have pics of the wheel and the fork? But yeah, once metal collapses like that with folds, its beyond repair short of replacing the tubing.

Unless you enjoy messing around with unremarkable old stuff, it'd prolly be a good move to donate it to a co-op for parting out.

Just curious, what would it take for you to say it was bent badly?

haha alright alright, i've never bent a frame before and until seeing these reactions I don't think I'd quite realised how ****ed up it was.
I'll post a pic of the fork/wheel bobotech, but yeah I am absolutely going to salvage the parts and either use them to build a new one or just donate them to bike pirates co op for somebody else to use.

This is sort of like posting a picture of a pretzel and saying your bread stick is slightly twisted.
To quote Mr. Python:
US: No no! 'E's pining!C: 'E's not pinin'! 'E's passed on! This parrot is no more! He has ceased to be! 'E's expired and gone to meet 'is maker!
'E's a stiff! Bereft of life, 'e rests in peace! If you hadn't run 'im into that sedan 'e'd be pushing up the daisies!
'Is metabolic processes are now 'istory! 'E's off the twig!
'E's kicked the bucket, 'e's shuffled off 'is mortal coil, run down the curtain and joined the bleedin' choir invisibile!!
THIS IS AN EX-FRAME!!
(pause)
You: Well, I'd better replace it, then.

That said, I sooner replace it than try to fix it, even as a temporary solution. There are lots of bikes out there...
