HV Racing HVR 50.4 MINI User manual
WARNING:
Read these operating instructions carefully before you start using your HVR!
Dear HVR customer,
Thank you and congratulations on purchasing an HVR Ele electric motorcycle.
Read the operating instructions carefully and completely to ensure safe and long-term operation of the HVR and act carefully during
operation.
The HVR is the electric motorcycle for children with a powerful electric drive that is perfectly adaptable to your child's riding skills.
Long travel times are possible thanks to the large battery capacity.
The electric drive system is almost maintenance-free and equipped with a large number of sensors to ensure easy and safe
handling.
Make sure your child is mentally and physically fit to ride a motorcycle. Safe cycling is a basic requirement for this.
Your child must always wear appropriate protective clothing when riding a motorcycle. At the beginning you explain to your child the
functions and controls of the motorcycle as well as the driving technique.
With the HVR Connect app, the power and speed of the HVR can be adjusted over a wide range.
With a low power setting, you can run alongside your child without any problems and support them with their first attempts at driving.
For experienced young racing drivers, the HVR can be transformed into a winning motorcycle with over 8000 watts of power and a top
speed of 70 km / h in a matter of seconds.
With this electric motorcycle we would like to give you and your child the opportunity to get into motorcycle off-road sport more easily and
have a lot of fun.
The parents also enjoy the low maintenance requirements and low maintenance costs. The low emissions, especially the low noise
emissions, make it possible to drive in completely new places and much more frequently.

5. ELECTRIC DRIVE
The electrical drive train of the HVR comprises the battery, the electric motor and the converter.
5.1 BATTERY
Page 8 of 36 HVR instruction manual
The traction battery is the heart of an electric vehicle, performance and range largely depend on the battery. The HVR lithium-ion battery has
a specially designed, highly developed battery management system (BMS), which ensures that the battery is always operated within the
permissible limits. A large number of sensors constantly measure the parameters of the battery such as the voltage of the individual cells,
current, temperature, state of charge (SOC) etc., the Battery becomes permanent monitored and protected by the BMS.
SOC (State of charge) Calibration:
The state of charge is calculated using the current and voltage measurement in order to precisely determine the currently available capacity
of the battery. It is recommended to discharge the battery to 0% SOC approximately every 10 charging cycles until the motorcycle switches
off. The battery should then be charged to 100%; this procedure calibrates the determination of the state of charge.
NOTE:
The BMS protects the battery from temperatures that are too cold and too warm. For driving in cold conditions, it is recommended to warm
the motorcycle in a warm place with approx. 10-25 ° before driving. This improves performance and range.
Very hot ambient temperatures and driving with high power consumption heat up the battery cells. The aluminum side covers serve
as heat sinks for the battery cells.
H
NOTE:
H
If the battery is too warm or too cold for driving or charging, the yellow LED on the display lights up and the BMS prevents driving or
charging until the battery temperature is again within the required range.
The battery temperature can be displayed with the app.
NOTE:
For safety reasons, the HVR 50.4 switches off automatically after a standstill for 60 seconds, unless it is connected to the app.

WARNING:
Risk of fire and fire
- NEVER open, damage or burn the battery.
- NEVER short-circuit the battery poles.
- NEVER reverse the polarity of the battery.
- NEVER bring it near heat or fire.
- NEVER try to use any charger other than the original HVR charger.
5.2 ELECTRIC MOTOR AND MOTOR CONTROL UNIT (INVERTER)
The HVR electric motor and the converter ensure that the power delivery is easy to control. No clutch or gear shift is required for driving, the
power is available when the driver wants it.
NOTE:
The HVR's electric motor has an innovative liquid cooling system to dissipate the temperature from the inside to the housing. The cooling is
designed for the life of the motorcycle and therefore does not have to be changed.
H
DANGER:
H
Do not open the motor, otherwise coolant will leak out. The motor may only be removed as a whole using the 4 screws at the bottom of the
mounting brackets, the mounting brackets remain on the motor.
Should any oil leak out, it can be refilled through the central screw 1 in the engine block. Use only HVR coolant
and only fill up to the hole.
