Segway Inc. is recalling all Segway PT i167, i170, and i180 models (i Series), p133 models (p Series), XT, GT, i2, and all e167 models (e Series). These personal transporters can unexpectedly apply reverse torque to the wheels, which may cause a rider to fall. This hazard occurs when the device is tilted back by the Speed Limiter and the rider comes off and then back onto the device within a short period of time. The recalled units were sold to both consumers and commercial customers.
If you own an affected Segway model, you should stop using the device immediately and contact Segway Inc. to receive a free software upgrade.
