How U2 Works 

TT  Includes  body,  motor  and  electrical  system.  The  motor  is  installed  at  the  two  sides  of  body,  and 
power  supply,  control  circuit,  driving  system,  sensor  and  control  switch  are  installed  inside  the  body, 
between the wheel and body is rotation, speed sensor and angle sensor they will transmit turn angle 
and dip angle information to the control center in order to balance U2

’s gravity center (combination of 

human and TT). U2 is just like human body, when your body bends forward, you will have to move a 
step forward to keep balance. When you stand on U2 and bend forward or backward, the power unit 
will  control  the  wheel  to  move  forward  or  backward  to  keep  balance.  The  handlebar  will  control 
steering function, when  you move the handlebar leftward, U2 will steer leftward; and when you move 
the handlebar rightward, U2 will steer rightward. When the handlebar is in the middle, U2 will stay in its 
direction.  The  built-in  inertia  dynamic  stability  system  will  keep  the  level  of  forward  and  backward 
directions, yet it can’t guarantee their stability. Hence, when the driver operates the U2 steering, the 
driver’s  body  shall  lean  with  the  steering  lever  in  order  to  control  the  steering  centrifugal  force  and 
enhance the safety steering. 

 

U2 INSTALLATION 

The content of this part is to check components that U2 contains and installation guidance. 

Check if All Parts in U2 Packing Box Are Complete

Install U2 

Step 1: Install the control shaft with the handlebar according to the direction shown in the figure (Mind 
forward and backward directions).  

Step  2:  Insert  components  of  the  control  shaft  into  the  body  as  the  direction  is  shown  in  the  figure 
(Mind forward and backward directions of the control shaft).
