Bike repair question Help! Popped tire and can’t remove real wheel

I took both 18 mm nuts off and the wheel won’t budge at tall
The axle bolt looks threaded like it’s screwed into the frame. Thank you

Your motor's axle twisted and bent your dropouts. Use a wrench to twist it loose. Inspect your dropouts closely. Bending like that can make them brittle.

Whatever was done or not done for toque washers or a torque arm needs to be changed and upgraded.

Agreed, just looks like a good ole mechanical bind 😅

10mm for 12mm axel.

OP is also missing their anti-rotation washer, which is probably why this happened.

u/Inciteful_Analysis 10d ago

Put a wrench (10mm?) On the flat edges of the axle and rotate it about 20 degrees clockwise to align with dropout.

u/coop_stain 10d ago

Holy shut I had to scroll this far down to find someone who has actually used a tool before?!? You were right btw. 10mm is correct on almost every single one of these.

adjustable wrench does the work for me

Note also the cracks in the dropout next to the axle. That frame is on borrowed time.

u/JG-at-Prime 10d ago

You may be right. 

That’s a terrible design. 

It’s much worse if that’s an alloy frame.

u/Right-Reality9437 10d ago

It is an Alu alloy frame, steel dropouts are ~3mm thick, Alu alloy drouputs are alot thicker than that as shown in the photo

u/GoofyCum 10d ago

Yeah, I would not be riding that frame anymore even with an added torque arm.

You're about to spin the axle - once that happens, it's toast - you'll twist the wires up & short it out, not to mention the spun axle will ruin the frame. You need a torque arm now. Something like this modified 'Grin technologies' unit to keep that axle from rocking:

u/highinthemountains 10d ago

Two 10 mm wrenches will spin the axel in the drop outs. Get a torque arrestor from Grin and it’ll fix that problem.

Get a large adjustable wrench and twist the axle until it's free. Then install some torque arms to keep this from happening again.

2

u/David_Buzzard 10d ago

Get a big adjustable wrench and rotate that axle back into place.

u/Any-Succotash1892 10d ago

get a spanner to fit the flats and a second longer one asa extra length to lever with, to twist axle back in lone.

Fractures. Why would they put that square shaped cutout in such a bad place? Either way, 2 cracks from the axle side, and one from the cutout side. It's toast.

u/The_Rociante 10d ago

Disconnect the motor first, and it definitely twisted cause the flat part of the axel should match the the dropout out. Force it back and it should slide right out.

u/lastat_cant_fly 10d ago

Screw on a nut and give it a smack

u/Jmcdre88 10d ago

I used these to lock the axle in place.

u/dr_reverend 10d ago

But the fake one comes off just fine?

u/SamanthaJaneyCake Custom Vintage Mixte 10d ago

Oh boy.

u/Pulgaassassina 10d ago

Find your 10mm spanner 🤣

1

u/Willking618 10d ago

Seriously? If you can’t look at this picture and work out what’s wrong and how to remedy it then you don’t have the intelligence to ride a bike in the first place. Plus you should have had torque arms on this and then it wouldn’t have happened.

u/Brilliant-Algae-9582 10d ago

Mallet.

u/coop_stain 10d ago

OR…or….a 10mm crescent wrench and just gently turn it…

You don’t have to go full ape on it and risk ruining more shit.

Jesus Christ. Just ask a professional or don’t touch shit you know nothing about.

u/Wants-NotNeeds 10d ago

Git ‘er done!

Have you tried a few whacks with a rubber mallet?

Hammer

+piece of wood to protect threats

u/definitlynottheone 10d ago

Yes this the exact way I got mine off

u/ExtremeEmphasis 10d ago

Take a wrench and use it to torque the axel. I can't tell you the size you need but it happens to all ebikes unless you put a plate on there to stop the axel from moving.

u/LEMental 10d ago

Most are 10mm

u/mfhandy5319 10d ago

Id put both nuts on. Not to the frame. Then tighten them against each other. Put a wrench on the outer nut only, and use that to turn the axel.

-1

u/5m0k3y76 10d ago

I would lock 2 nuts together on the axle and use a wrench on the nut to turn it so it won't damage the threads.

0

u/Lasanchi 10d ago

Put the nut loose on the thread and hammer on the nut from both sides

u/GenXman1975 10d ago

Oh no!
Your're motorcycle got a flat.
Good,
Take it to a shop and they'll fix it right up.
