King Song S18 Sporty EUC


1. Sports Bike inspired design. Aerodynamics with air intake system. Aggressive curvature design
2. Variable Linkage dampening air suspension system using 200-57 suspension
a. X shaped suspension travel of 100mm
b. Suspension is interchangeable and allows for personal modification and custom ride style
c. Adjustable air suspension system from on to off. Off state still reacts to big bumps but will ride similar to a wheel without suspension.
d. Rotary switch for sensitivity adjustment
e. Different pressurization can be adjusted to according to rider weight

3. Padding designed in cooperation with Kujirolls
4. User Experience focused ergonomic design to connect wheel with rider
5. 12 MOS design connected to aluminum body frame for fast heat dissipation without the need of fan
6. Headlights are 2 times stronger to the 16X with 2*5w (high beam) and 2*4w (short beam) with automatic sensor to switch between modes
7. Ergonomic handle designed for pushing and lifting which can be hidden inside body frame when not in use.
8. First ever high performance wheel with limited wiring with all key components housed on PCB
9. Rear light dislaying battery level, braking and turning signals all within one singular unit.
10. 21700 Battery system for better; efficiency to space ratio

EUC Port

Charging port; Switch port; Light sensor port; USB discharge port

Light UP Displays

Rear light housing displays battery level, braking and turning signals all in one unit

Protective Measures

Lift Sensor

Lift sensor accurately senses and determines when wheel is lifted off the ground to stop tire rotation.

Roll Protection

45° left and right side. ( Motor stalls when over 45° )
Place the machine vertically on the ground will restart automatically, no need to restart manually

Speed Limit Protection

Beep alarm or voice alarm when exceed limit speed

Low Battery Protection

Low battery protection activated on 30% battery, speed will decreases linearly; when the battery is lower than 5%, voice alarm for charge, when battery at 0%, the front part of the pedal will rise to decelerate until full stop

Higher Temperature Protection

When the motherboard reaches 80C it will result in tiltback. When the motor reaches 120C it will result in tiltback.

Alarm & Features

Swith On/Off

Short press power key: turn on
Long press: hear a click then turn off

Battery Indicate

Led shows battery level when EUC power on at rest

Hardware Features


The motherboard is designed with a 4 layer structure, allowing for better stability performance. 12 large individual TO-247 imported MOS to sufficiently support the 2200W motor. MOS is attached to the aluminate body frame of the wheel for better heat dissipation.


Bluetooth 4.0. Allowing strong stable data transmission

USB Output

Quick charge 3.0

Front Light

2*5w light high beam with 2*4w short beam. Double the strength of the 16x, providing excellent illumination at night

Temperature System

Temperature of the motherboard is continously closely monitorered to ensure rider safety


Aluminum constructed handle designed for ergonomic pushing of the wheel or lifting of the wheel


Higher power 2200w motor that provides a maximum torque of 140N.m providing fast acceleration

Suspension System

Unique X shaped suspension system. Racing level suspension provides the ultimate support and shock absorption
