I mean, bikes are weird though right? They actually have multiple modes of steering. You're right, the standard mode is to lean the bike which causes the steering, however you generally counter turn the wheel to initiate the lean. Most bikes are much too stable to lean purely with weight alone.

Secondly, at lower speeds and higher turning radius' bikes do in-fact steer with the front wheel, counter to their lean. Often encountered while navigating a parking-lot for example. I imagine an All-terrain bike is more likely to be needing to operate more often in this envelope however, so am also a bit confused on how it's anticipated to work.
