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
1. Body
2. Control shaft
3. Handlebar of control shaft
4. Charger
5. Toolkit
6. User Manual and Warranty Card
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).
