General Technical Requirements of Electrically Driven
Vehicles for Children
1 Application Scope
This Standard specifies the general technical requirements and test methods for
electrically driven vehicles for children.
NOTE The safety requirements for electrically driven vehicles for children are specified in GB
6675.1 to GB 6675.4 and GB 19865.
This Standard applies to electrically driven vehicles for children under 14 years old.
This Standard does not apply to electrically driven vehicles for children for the following
intended applications.
-- special-purpose electrically driven ride-on vehicle for children, such as electrically
driven vehicles for children for beach and electrically driven vehicles for children for
racing; and
-- electrically driven vehicles for children for public places and commercial purposes.

3 Terms and Definitions
For the purpose of this document, the following terms and definitions apply.
NOTE The term “month” used in this Standard indicates a complete number of months (e.g.
18 months indicates 18 months old and below).
3.1
Electrically driven vehicles for children
the toy vehicles intended to be ridden-on by children under 14 years old, driven by
electric battery and not intended for traffic, such as the electrically driven vehicles for
children including bicycles (equipped with jockey pulley devices), tricycles and
quadricycles.
3.2
track
the distance between two wheels sharing the same axle, i.e. the external dimension of
two wheels in contact with the ground. If the wheels have a second contact surface
with the height difference not greater than 3 mm in the design, they can be deemed as
the actual contact points.
3.3
steering gear
the mechanism assembly which is used to control the direction of vehicles manually or
remotely
3.4
basket
box (basket) or similar device on vehicles used for decoration or to carry a small load
3.5
assist-push-rod
the mechanism with which a guardian helps riding children go forward and backward
or steer through a push rod
3.6
jockey pulley device
4.5.3 Remote-control distance
Under regular service conditions, the maximum remote control capacity tested in
accordance with 5.6.2 shall not be less than 80% of the nominal remote control
distance or range value of the products.
4.5.4 Key configuration
Remote control shall not be provided with vehicle automatic driving key or automatic
switch or similar key functions.
4.5.5 Drop resistance of remote control
After the drop test in accordance with 5.6.3, remote control shall not have any structural
or functional damage.
4.6 Control device
4.6.1 Location and operating performance
The devices used to control all functions and speeds of electrically driven vehicles for
children, including switches, keys, rotary knobs, handles and rotary handles, shall be
at the locations convenient for the operation of consumers, which shall be convenient
for operation without distinctive jamming. The designed automatic reset device shall
reset automatically during the operating process. The speed-control rotary handle shall
be installed at the right-hand location of the rider. It shall be tested in accordance 5.7.1.
The low value point can accomplish zero potential and the high value point can
accomplish rated voltage/ current value. In absence of external forces, it reset zero
potential automatically. The rotary handle shall be capable of regulating the speed of
vehicles smoothly without distinctive impact.
4.6.2 Displacement and run-out of speed-control rotary handle
Speed-control rotary handle is tested in accordance with 5.7.2. The axial displacement
of speed-control rotary handle shall not be greater than 1.0 mm and the radial run-out
1.0 mm.
4.6.3 Strength
It shall be tested in accordance with 5.7.3. The control device shall have no functional
damage after the test.
4.7 Breaking device
4.7.1 Design and operation
The breaking system shall function effectively without distinctive jamming. If a foot
brake is designed, the area of pedals shall not be less than 15 cm2 and the pedal
surfaces shall be slip-resistant.
4.10.1 Pedal design
Pedals shall be designed with a skid resistant structure. Their width measured in
accordance with 5.11.1 shall not be less than 60 mm.
4.10.2 Center distance of pedals
The distance from the center point of one-side pedal to the vertical plane of vehicle
center shall not be greater than 1/2 of the maximum track of vehicles; if the distance
from the center point of one-side cent...
