Note: obviously it's not a direct comparison. The car & motorcycle are faster than the e-bike. So their efficiency is calculated at a higher average speed.

But the imbalance is countered somewhat by the fact that we're comparing the best case efficiencies of the car & motorcycle, vs. a flat-out worst case run on the e-bike.

Yes, I avoided using the brakes as much as possible, but I did not drive for load or accelerate gently to minimize resistance & Peukert losses, as I try to do in the car. No, I pretty much had the twist grip pinned on "GO!!!" for the full 8.7 km.

Also worth noting: if I'd pedalled some, maybe I could have doubled the electric efficiency. Not an option (yet! ) in the ForkenSwift or on the motorbike.
