Seized pedals

Update:
I took my bike to the local pro shop and they had them off within five minutes.
Lesson is: the bigger the spanner the better!

I would invest in a cheater bar. Mine is a 2 ft length of scaffold pole which I got from the local metal recycling/dump. I slide it onto the end of a large spanner and the extra leverage makes a huge difference.

One warning though. Make sure when you do this you use the largest adjustable spanner you have. I once put the cheater bar over a smaller spanner and managed to split the metal near the jaws (basically wrecking the spanner).

Yep, that technique also works with those 90° Allen keys, if you use the ring end.

That's a worrying image why do you need to tighten the bolts up that tight?

I’ve had some success using a 1/2 inch socket (with an Allen key bit) with a breaker bar. Yellow Saddle is right none of these propriety anti seize products do a lot of good, you just need lots of leverage. I also use a bit of copper grease when I fit new pedals, there is no need to over tighten them.

This. Well, I use a 3/8" breaker bar but otherwise..

Never had issues using this method (although not done a lot of pedals), but if I still had problems next stop would be heat and oil.

Pour boiling water over the crank and immediately attack with the pedal spanner.

Fixies are easier to get pedals off!
