Please do not arbitrarily modify the part of the U2, this will affect its performance and damage it, and
maybe it will cause a serious damage.
Weight Limit of the Driver
The reason for limiting the weight of driver are as following:
Guarantee the driver’s safety.
Reduce the damage to U2 cause by overload.
Maximum weight limit of the driver: 80KG
Minimum weight limit of the driver: 25KG
WARNING! Overweight will make you be in danger of falling over.
Maximum Driving Distance
Maximum operating range of U2 is influenced by many factors, such as:
Ground type: the driving distance will be increased when it is driven on smooth and flat ground. On the
contrary, the driving distance will be reduced.
Speed and driving style: keeping medium speed will increase driving distance. Frequent stopping,
accelerating and decelerating will reduce driving distance.
Weight of the driver will influence the driving distance. Store and drive U2 under recommended
temperature value, the driving distance will be increased.
On the contrary, the driving distance will be reduced.
Speed Limit
When the driver drives U2 at a speed approaching the maximum permission speed, U2 handlebar will
actively lean to the driver, which is reminding the driver to stop accelerating; When the driver drives
backward at a speed approaching the limit speed for driving backward, the buzzer will sound an alarm
which reminds the driver to decelerate or to drive forward.
NOTE:
Please, do not drive or steering on the slope, which will cause misregistration of balance angle
of U2 and influence the driving safety.
Alarm and Warn
U2 will give an alarm and warn the driver under the following situation: (1) over-speed driving forward
(2) over-speed driving backward (3) User tries to get on U2 in charging mode. Please stop incorrect
usage immediately under situation (2) and (3). If violent vibration occurs in the process of driving,
please get off U2
immediately. Please don’t continue driving in the process of vibration.
WARNING! When the driver gets off U2, it will keep balance for one second.
