I don't know what "total transport efficiency" is or how is it measured, I just noticed you mentioned 70% of energy wasted by ICE as if humans waste less than that. As for more efficient than anything else in terms of MPG, you might want to check the current MPG record, it's in range of 15K MPG on some hydrogen powered car if memory serves.
A human on a bicycle is efficient because of mass and that the bicycle itself is a very efficient machine. A cyclist will burn around 30cal/mile of riding. If a gallon of gas has about 31.5k kcal of energy, then that's about 1,000MPGe for a human on a bike. A 200lb person + 20lb bike requires very little energy to overcome rolling resistance compared to a 2000+ lb ICE vehicle that spends the majority of its energy just to move its own mass.
