I was wondering, if I hit backpack first would an equal amount of energy be transfered with less shoulder crumple?
@IR, I'm 6'1 and yeah the natural thing to do is try to go over things, but I recon I can get my mass down low for a hit. #poloplayer #examericanfootball
As much as tipping one on it's back looks like fun I'm less sure I could get an up and over push from my bike on the front.

Have your calculations taken into account the body mass of the fat blonde/estate agent/fat blonde estate agent driving said vehicle?

The camber of the road should help a little.

Whatever you crush at the interface (Khornight, backpack, helmet or body panels) will absorb energy, and we've already established that you don't have enough energy to knock over a smart car, so it's probably best to save yourself and use your strength to flip it onto its back later.

I think it's reasonable to assume an inelastic collision, in which a crushed and broken combination of Khornight2 and bicycle temporarily sticks to the side of the car before falling away in a crumpled bloody heap. In which case, conservation of angular momentum (with the pivot point at the base of the car's tires on the far side) will give the initial angular velocity of the car's CoM, from which we can work out how much kinetic energy was delivered.
Do you still have the figures you found for the car's mass, width and CoM height ?
