i couldnt care less either way if theres a button,each to their own,but there HAS to be a kicker as well on any bike i will own.As for getting crossed up and not bein able to kick,that usually happens when you cant plant your left foot anywhere.in this situation get off the right side and roll the kicker with your left foot,often you only need to roll it through halfway.in very rare situations there is no room to open up the kicker(ie jammed in a ditch)
the correct method here is not to cry for an e start,but just admit you f#*ked up and muscle it out!
