Bikes: too many bikes from 1967 10s (5x2)Frejus to a Sumitomo Ti/Chorus aluminum 10s (10x2), plus one non-susp mtn bike I use as my commuter

It's a common misconception that we somehow "balance" a bicycle. The reality is that we're in a constant state of falling to one side or the other. We stay upright by steering the bicycle back under our center of gravity, using the same mental/physical processes we use when walking and running.

With some experience, we detect and respond to the beginning of a fall sooner and need ever smaller corrections. This is also why riding very slow is difficult. With greater speed the time, required for the front wheel to track back across is shorter, so our corrections happen that much faster before we're as far off out point of balance.

Bicycle fork geometry, and mechanical steering forces help, but the core of the process is learned reflexes, which is why it's nearly impossible to ride a bike where the steering inputs are different or reversed.
