I was riding when I suddenly had the pedal come off. I got the bike home and tried to screw it back in unsuccessfully. It is slightly off straight. Is this repairable, or do I need a new pedal and crank? Super bummed out. I just got it back from a tune up at my local bike shop.

You most likely need a new crank arm and pedal. Luckily it shouldn’t be expensive, judging by the bike
Can you check your crank to and pedal to see if you stripped out any threads when the pedal came off?
I’ve had the issue on a mountain bike where in a rush to get on the bike after a rebuild, I didn’t fully torque down the pedal. When the pedal came out, it stripped out some of the threads in the crank.
Yeah. I screwed it in from the reverse side and it sat perfectly, but some material from the threads came out, and when I tried to screw out in from the proper side it was angled again. I just dropped quite a lot only for both the bikes I brought in to be fucked within a two rides.
I think you already know the answer sadly. Unless the LBS can rethread the crank arm, you probably just need another crank.
I would go back to the LBS that did the tuneup because one would think that a simple bolt-check would be on the tuneup list to avoid situations exactly like these. It costs them nothing in materials and very little in time to check and torque all the bolts and pedals.
That said, I wouldn’t come at them in an accusatory manner but maybe ask if they can cut you a deal on a crank since it just came from a tune up and that you’re disappointed to have to replace something immediately after service. They should at the very least comp you the labour for install since, IMO, they shouldn’t have loose pedals leave the shop on a bike that was just tuned up.
You probably stripped out the crank arm. Most bike shops can put what’s called a Helicoil in it to fix it, or you can DIY for cheap. Most auto shops and hardware stores have kits and plenty of explainer videos on youtube. Pedal likely shot.
Get it tapped and run the pedal back in.
Unrelated, but did that saddle and bar tape come together as a combo on Ali Express or something? Only asking cause I bought a 2nd hand Kona Jake on Marketplace that came with that exact same combo
Thread it through from the back and hope you can fix the fucked up threads. That might hold for a bit, if you’re just after keeping it alive you can jb weld the pedal into the crank after “fixing” it, because you’re probably going to wreck the outer 20% of the threads.
I doubt the shop pulled your pedals off but it’s worth talking to them, if they didn’t tighten them back and you stripped em riding they should cover a new crank, or at the very least give you labor on a new crank install and budget cranks are super affordable to get you riding.
