at a glance everything about the 7 is upgraded bike component wise... the motors are the same.

also you don't need a comparison page.. just look at the specs pages for each and compare....

Like the original poster I was comparing the 7 and 5.
The obvious difference I noticed was the wider tires on the 7 (2.8") vs the 5 (2.35").
I've not done well with wide tires, which I know makes me counter to all of the popular trends (they just bounce too much laterally for me, so tracking gets difficult).
Some component differences; brake Shimano M6000 vs M315
Gears: 11 vs 10 : the 7 goes to a 46 tooth but the 5 only goes to a 42 tooth
Derailleur: Shimano Deore XT M8000 vs M6000
Side by side comparison:
Fly 7 vs Fly 5
