7

Lifetime
After 300 to 500 full charge cycles, the battery will only provide 70% of its original
capacity. This number of cycles will be strongly influenced by the number of
outputs, the driving style and the storage temperature.
Storage
For optimal storage, it is recommended to store the battery in a dry and temperate
place (between 10 and 30°C).
Below 10°C, the useful capacity of the battery can be reduced by 30%.
In the event of a long period of non-use, it is advisable to store it in a state of charge
at 2/3 of its capacity (no-load voltage of 52 V).
Maintenance
It is recommended to perform a 24-hour maintenance charge every 5 cycles to
ensure cell balance and optimal battery performance.

OTHER POSSIBLE COLORS - BATTERY LED
3 possible codes apart from the colors seen above :
●Alternating BLUE/GREEN flashes ⇒Need to recharge
●YELLOW flash ⇒Temporary error (contact LMX support)
●Flashing RED ⇒Permanent error (contact LMX support)
4. POWER MODES
The change of power modes is done via the Smart LED on the handlebars, or
directly via the application (see page 39).
The LMX 56 has a Neutral (N) mode and 3 power modes: an
ECO mode, a MID mode and a HIGH mode. An N (neutral)
mode is also present.
These modes can be configured directly on the application
via the motor tuning tab (see page 42).
ON THE SMART LED
●Manage the 4 modes of your LMX by pressing the
“MODE” button on the LED. Each press advances
one mode in a cycle. The modes are identified by
these colors :
- WHITE for N/0 (Neutral) mode
- GREEN for mode 1 (Eco)
- BLUE for mode 2 (Mid)
- RED for mode 3 (High)
When the LMX 56 powers up, it is automatically in N (Neutral) mode.
The Smart LED also gives access to the battery level when you ride : without
clicking on the MODE button, the Smart LED displays the battery level by default.
- 60-100% = GREEN
- 40%-60% = YELLOW
12

- 20%-40% = ORANGE
- 10%-20% = RED
- 0%-10% = FLASHING RED
●When the LMX 56 has just connected to the app, the Smart LED turns
BLUE for 5 seconds.
ON THE APP
Possibility to switch between modes directly via the application by pressing the
arrows on the dashboard (see page 40).
COMMENT : On street legal models, as long as the kickstand is down, it is
impossible to change modes and start the LMX. Lowering the kickstand
automatically returns to N mode.
MOTOR TUNING - APP
The modes of your LMX can be configured directly on the application on the
Motor Tuning page.
Set for each mode :
●The max power (W)
●Max speed (km/h)
●The max torque (%) - Pedaling assistance
●The level of acceleration (%) - Twist grip on the handlebar
IMPORTANT
IN MODE 2 or 3, DO NOT TURN THE THROTTLE FULL WHEN THE LMX ENGINE
IS BLOCKED (0 rpm).
⇒RISK OF DAMAGE TO THE CONTROLLER
Example : rear wheel locked with the brake.

5. USING THE DROPPER SEAT POST
Unlock the seat post :
●Press the lever located on the
left side of the handlebar.
●The saddle then rises
automatically.
Lower the seat post :
●Push down on the saddle
while pressing the lever to
lower it to the desired level.
6. USE OF SPEEDS
The LMX 56 comes with a 12-speed
drivetrain.
Use the handlebar controls to adapt
the gear engaged to the terrain.
⇒As a general rule, to limit power
consumption, it is better to turn
faster when climbing than to press
very hard on the pedals. Motor
assistance is proportional to pedaling
power.
14

7. BREAKING IN THE BRAKES
Attention, it is important during the first use to carry out a running-in of the brakes,
in order to ensure efficient and noiseless braking.
Running in forms the wear layer of the brake disc. To avoid surface icing, which can
cause noise during braking, it is important to follow the break-in
recommendations:
- When using for the first time, avoid continuous braking at low power, for
example on a descent.
- Focus on short braking spurts, which will deposit a layer of pad dust on the
disc and prepare the braking surface for optimal, noise-free performance.
Be careful, the braking performance will increase significantly once the break-in
has been carried out correctly. Particular attention is required during this step,
especially at the front brake.
SAFETY INSTRUCTIONS
Before driving, the owner of the LMX should read the following safety instructions:
The LMX 56H is a 50cc moped approved vehicle. It must therefore be used on land
authorized by the regulations in force in your country (L1e-B).
The LMX 56T is not homologated and is designed for use on private land only. It
should not be used on public roads.
Off-road driving can be dangerous. Control your speed and always be prepared for
the unexpected. Wearing safety equipment is mandatory: helmet and
homologated motorcycle gloves are the mandatory minimum.
Wearing back armor is highly recommended. Before driving, find out where you are
riding and stay out of restricted areas.
Although electric and pedal-operated, the LMX 56 is still a motor vehicle and should
not be used in areas where motorized vehicles are prohibited.
15

Electrical systems such as batteries, motors and controllers can get hot, so avoid
touching them after a ride. Batteries and systems can catch fire if impacted or
misused. In this case, stay away from fire. Do not breathe vapors and use dedicated
extinguishers. Powder (CO2) extinguishers are recommended for battery and
electrical fires.
If the frame is damaged in an accident, do not use your LMX 56. A damaged frame
can cause a dangerous failure at an unexpected time. Please contact us as soon as
possible to replace your frame and ride safely as soon as possible.
Always test your LMX on a smooth surface with suitable protective equipment.
Do not let inexperienced pilots test your LMX if it is in a high power mode.
WARNING
When working on your LMX and performing maintenance or cleaning, always
unplug the main power or remove the battery.
Always keep in mind that an electrical fault can cause the engine to run at any
time if the vehicle is powered on.

Braking check before each ride
As an electric vehicle, the required maintenance of the LMX 56 is simple.
Maintenance consists mainly of :
●Clean and grease the chain after each ride,
●Keep the nuts tight,
●Maintain correct tire pressure.
Suspension components require regular maintenance in accordance with the
manufacturer's recommendations. Drivetrain components such as chain, belt and
sprockets should be replaced every 2 years or 1500 km in off-road use, unless there
is abnormal wear.

3. LMX 56 WASHING
●Remove the battery when washing your LMX,
●Use a specific liquid soap, a specific brush and a damp towel to
clean the LMX.
●It is essential to keep the water jet at a minimum distance
of 40 cm, avoiding delicate parts (battery, battery rail,
bearings, axles, etc.).
GOOD PRACTICE
Wash your LMX with the hatch in place to limit the presence of water near the
electronic / electrical components.
⇒Risk of damage to components
TO AVOID
●Use as little water as possible on all electronic elements to reduce the
risk of water infiltration (battery rail, battery, motor, seatswitch/input
charger),
●Avoid watering the screen, because even waterproof, fog may appear on
it between the outer shell and the inner part,
●Do not use a high-pressure washer, as this may damage the decals or
internal components and thus affect the performance and durability of
the vehicle.
4. LUBRICATION
The lubrication of your vehicle always comes after a good wash.
●A first cleaning phase can be carried out using a WD40 type
penetrating product (do not put it on the discs: risk of
contamination of the pads),
●Wipe the chain with a cloth,
●Grease the necessary parts.
