Stick Shake Warning - Segway PT x2 Reference Manual

Stick Shake Warning

One of the ways that the Segway PT notifies you when you are at risk
of falling is by shaking the Handlebar and making growling noises.
This is called the Stick Shake Warning. The Stick Shake Warning can
occur in conjunction with, or independent of the Speed Limiter and
Safety Shutdown alert, depending on your riding situation (see
Figure 18).
