And of course there is the other approach. Armour the crank end. Use those indestructible double sided Shimano SPD pedals. And make it known to that wall if it tries to stop you, it will pay. Then just do it. Eventually you'll blast a path through. (You may eventually have to armour the entire bike but those paths will happen a lot faster when you hit with your 20 pounds of bike and 80 of case hardened steel.
(And you'll develop some real climbing legs.)
