Low Battery Alarm:The nixie tube of the unicycle shows you the battery level (10 bars). If battery power is more than 85%, the nixie tube shows full bars. As the battery power is used, the battery bars decrease. When battery power left is less than 10%, the nixie tube flashes and the buzzer rings. In this case, you are not advised to ride the vehicle any longer. Check battery level each time you want to ride the vehicle. Speed Limit:Its maximum speed is 18 km/h. If the riding speed reaches 13 km/h, the buzzer will ring and the pedals rise, alerting riders to slow down. In this case, you are advised to adjust your center of mass, avoiding potential risk due to loss of control.

Leaning Protection:If the vehicle tilts less than 45°, the buzzer will ring for alarming. This helps eliminate the risk of personal injury by the high-speed running vehicle if users are falling down. Restarting the vehicle will clear the alarm.

Charging Protection:If the battery is fully charged, the protection system will act, preventing damage to the battery even though the charger is not removed.

Dustproof and Waterproof Protection:It can be protected against intrusion of any object; run in 5cm deep water or snow, and ridden in drizzly days for a short period of time.
