How do you rate the rate the Giant road E and are there any minus points.
I would rate it as the best bike I have owned.
Negatives mean being really picky, but..
1/ Its not easy to shift up to the big ring when not under power, and I fancy that doing so will wear it out (shifting up under power is perhaps the main cause of chipped teeth) . By this I dont mean it wont change up, I mean you have to be sure to ease off if under the cutoff. I have found the quickest way away from the lights is to set off in 4th on the 34T inner, spin it up and then shift to the 50T outer with the sudden cadence drop bringing the power on tap in a very satisfying way.. To stay on the small ring means you are quickly up to 10 or 11 shifting 2 or 3 at a time.
2/ Power drops off at low speed with high cadence.. Not sure exactly as I dont yet have a cadence sensor on but if you like to spin up to 100 rpms in a low gear there isn't much help from the motor if under the cut off.
3/ The mode buttons are in a bad place and are a bit hard to push, but that's the drop bars with not too many mounting options.
4/ The charger plug is awkward to push in but there is a knack to doing it.
As I said really picky, not complaints, nor even grumbles....
If I could change one thing (excluding the display) I would go 48T on the outer ring (an old man thing...)
