it's not just save a newbie stuff we're concerned with. sometimes refreshers or reminders are good for all of us. heavy front braking even if the wheels are straight can cause a problem too. know your bike. know your grip and how the brakes respond individually and together in all kinds of weather conditions. always good to check that before you head out OTR.
i went absolutelyairborne many years ago off a bicycle trying to avoid getting in an accident. water bottle in left hand my reflex went for the front brake(aka free hand) rather than ditching the bottle and using both brakes.
still holding onto the bike i flipped buttoverhead then crashed down hard bike on top of me. broke two ribs and got cut up pretty bad. and that was just on a bicycle.
