General Specifications of Electrical Self-balancing Vehicles
1 Scope
This document defines the terms and definitions of electrical self-balancing vehicles, specifies
the classification, technical requirements, inspection rules, packaging, transportation and
storage requirements of electrical self-balancing vehicles, and describes the test methods.
This document is applicable to the design, production and sales of electrical self-balancing
vehicles that use batteries as the power source, except for military, police and other special
purposes.

3 Terms and Definitions
The following terms and definitions are applicable to this document.
3.1 electrical self-balancing vehicle
A wheeled manned mobile platform that is based on the inverted pendulum model and the
principle of static instability, and is equipped with a rechargeable electric drive system, thus
maintaining dynamic balance in an autonomous or manual mode of operation.
NOTE: the electrical self-balancing vehicle is referred to as the self-balancing vehicle for short.
3.2 steering column
A component used to control the steering of an electrical self-balancing vehicle, which may be
equipped with other electronic displays or lighting equipment.
3.3 remote control software
An application software installed on an intelligent mobile terminal to set up, control or monitor
an electrical self-balancing vehicle via a wireless connection.
3.4 safety alarm
An alarm (such as: sound, light and vibration, etc.) that may be clearly noticed by the user after
being sent to the user, when an electrical self-balancing vehicle detects internal faults (such as:
abnormal battery voltage and balance control unit failure) or dangerous driving actions or
abnormal working conditions of the vehicle.
3.5 brake
An action of an electrical self-balancing vehicle to stop or decelerate its wheels by self-
induction.
3.6 rated mileage
The mileage accumulated during the period when a fully charged electrical self-balancing
vehicle runs at a constant speed of 60% of the maximum speed prescribed by the manufacturer
on a flat hardened surface at a total load of 75 kg at room temperature, then travels at the
maximum speed that it can reach in the case of failing to run at the speed above due to low
power, until the self-balancing vehicle is unable to continue running due to low battery power.
NOTE: rated mileage is in unit of kilometer (km).
4 Classification of Electrical Self-balancing Vehicles
4.1 In accordance with the number of wheels, it may be classified as:
a) electrical one-wheeled self-balancing vehicle -- an electrical self-balancing vehicle
with only one wheel, including two tires on one wheel;
b) electrical two-wheeled self-balancing vehicle -- an electrical self-balancing vehicle
with two wheels;
c) electrical multi-wheeled self-balancing vehicle -- an electrical self-balancing vehicle
with three or more wheels.
4.2 In accordance with the steering mode, it may be classified as:
a) electrical self-balancing vehicle with a steering column;
b) electrical self-balancing vehicle with no steering column.
4.3 In accordance with whether the seat is equipped, it may be classified as:
a) electrical self-balancing vehicle with a seat;
b) electrical self-balancing vehicle with no seat.
4.4 In accordance with the charging mode, it may be classified as:
a) rechargeable electrical self-balancing vehicle with external power supply -- this type
of electrical self-balancing vehicle is not directly connected to the AC grid during
charging, but connected to AC grid via a charger or external power supply for
charging;
b) rechargeable electrical self-balancing vehicle with built-in power supply -- this type
of electrical self-balancing vehicle is directly connected to the AC grid during
charging.
5 Technical Requirements
5.1 Main Technical Performance Requirements
5.1.1 General
The design of the main technical performance of the self-balancing vehicle shall firstly satisfy
the requirements for safe driving.
In terms of the tyres of the self-balancing vehicle, the minimum diameter is 125 mm and the
minimum width is 25 mm.
Refer to Appendix A for the analysis and evaluation of necessary conditions for the safe driving
of the self-balancing vehicle.
5.1.2 Maximum speed
In accordance with the maximum speed test in 6.2.1, the maximum speed shall not be greater
than 20 km/h.
When the user stands on the vehicle for a long time, each pedal shall be equipped with a non-
slip surface with an area of not less than 150 cm2.
When the user stands on the vehicle for a short time and the vehicle is equipped with a seat, the
non-slip surface of each pedal shall be at least 65 mm in length.
5.2.5 Switch
The electrical self-balancing vehicle shall be equipped with a master control set that is apparent,
easy to access and not easy to operate incorrectly to turn on and off the driving power. In
addition, this set shall be triggered by the user’s autonomous behavior(s).
5.2.6 Foldable mechanism
The foldable mechanism (if any) of the electrical self-balancing vehicle shall be designed to be
