I have a 2020 Explore E+4 and do not have the same issues. I'm in New Zealand so maybe some model differences? I think the bike is amazing, so happy with it. 10/10 easy for the money paid. Goes anywhere does it all (within reason)
Just some answered below..
1) The terrible Owners Manual.
What are you missing?
2) The only slightly better fork manual
What are you missing?
3) The shifter levers: If you move the set so that the down shifter lever doesn't rub against the base of your thumb it is then hard to reach the up shifter lever.
?? Mine is perfect, maybe the shop tech set it up wrong?
4) The fact that the heel of my left shoe hits the kickstand when pedaling.
My kickstand mounts are back by the rear axle/hub... Never comes close to hitting
5) The seat post doesn't allow the seat to slide back enough for proper knee pedal alignment.
I'm 6' 6 and have XL frame. No issues at all. Is your bike proper fit?
6) the fact that Giant eliminated the computer read-out and gives you the Bluetooth option instead.
I like the minimalist approach, may still get a Ridecontrol Plus once avail but plenty of apps avail for all the info
7) That there is no good place to mount a water bottle holder.
It has mounts, What do you mean??
Anyone considering this bike, I highly recommend.
