Bought the bike a week ago, assembled it myself so warranty isn’t going to cover it. I’ve checked other cases like that but I’m not sure how bad mine is. I checked a pedals twice before riding out before and still didn’t realize I somehow didn’t screw it in properly🤦♂️
I would be grateful for any advice I really do how I fucked it up like that.
EDIT: brought it to the store, getting it fixed for 45aud until tmr morning. Turned out it’s not too big of a deal.

It can’t hurt to contact Kona and inquire about a replacement crank.
Or a replacement crank shouldn’t be too bad. In rather scenario, get a shop to throw it on for you and do once over on the bike.
The tread is gone so you got 2 options. The cheaper one is to have it repaired with helicoil. Or just getting a new crank.
Get something called a helicoil. It can save the crank. In the future, grease the threads of pedals and initially thread them CAUTIOUSLY until you know they’re threaded correctly.
Just happened to me, had to get a new crank
New crank new pedals, take it to a shop
Screw the pedal in from the back to clean up the threads then re do it from the front carefully to make sure it catches straight then it should work. Test it carefully before you decide whether to replace.
Was it not all the way in and then ripped out during riding?
Other than that, this happens when people mix pedal sides, trying to install the right pedal left, with force. In that case, the other side is probably done too.
Other than that, it could maybe have been misalignment, but that should have been noticable.
For the first 98 % of threading the pedal in, you shouldn’t need tools at all, or only two fingers to turn the hex key. If there’s any resistance, something’s wrong.
What crank do you have? Just pick up a second hand one.
There goes another left crank arm… OP probably tried to screw the pedal in the wrong way, and or didn’t grease the threads…
So many questions.
Did you have to put a lot of effort in to get the pedal in?
Did you screw the pedal in the whole way? Did you use any force to tighten the pedal (you really don’t need a lot).
Did you use any form of grease or lubricant on the threads?
I have a general rule when assembling new things – if it doesn’t go together easily or you need to use a lot of force to put things together, you need to investigate why. If you just yeeted on the spanner until it was in, that is where costly mistakes happen.
If you want to DIY, get a new crank. Fitting a helicoil requires a degree of mechanical aptitude that may be above your current level.

It is too late for this one and you might already know this, but this video for reference does wonders: https://www.youtube.com/watch?v=qTtxoheAG10
Wait, did LG make bikes?
Does Kona ship direct to consumer now? I thought they were a bike shop brand
Did the left pedal feel gritty or resistant right from the first turn? Left side threads backwards so folks muscle it the wrong way and this is usually the result. Also worth checking if it had any grease on it before you started, dry aluminum on aluminum chews threads fast.
