The foot shifter is a pedal shifter, only controlled by your foot and not your finger it is all electric.
That foot shifter connects by wire to the bike.
Yes , but it's just a matter of what someone is used to. Muscle memory and all. Like I said, I wouldn't buy it right off unless it seemed shifting manually by the handlebar buttons was less intuitive. Probably would quickly adjust. It's just nice to have the option.
