LED state of charge
Check the battery charge level by pressing the battery on / off button. The charge
level is indicated by leds, which are illuminated differently depending on the charge
level.
Charge the battery
You can charge the battery either when it is assembled on the bike or when it is not
assembled.
Lithium-ion batteries are not subject to memory so you can recharge the battery at
any time even after a short journey. Charge the battery at a temperature between 0 °
c and 45 ° c (ideal temperature around 20 ° c).
Read the charger instructions (inside the box) before charging the battery.
Proceed as indicated:
1. Insert the charger cable plug into the battery socket and then the charging socket
into the electrical socket.
2. As soon as the cable is plugged into the electrical socket, a red LED lights up.
3. When the charge is complete, the LED will be green.
Charging time depends on various factors. It can vary depending on temperature, age
and use and battery capacity. If necessary, you can nd information on charging times
in the battery technical data. When the battery is fully charged, the charging process
stops automatically. Remove the socket from the battery and the electrical outlet.
Use the own battery charger of the battery.
Be sure to use the correct main voltage. The correct main voltage required is
indicated on the charge. It must respect the voltage of the current source. The 230V
chargers can also operate at 220V.
Warnings
• Do not touch the socket with wet hands to avoid shock.
• Before using the charger, the cable and the socket, check that they are intact. If
there are any damage, do not use the charge to avoid electric shocks.
• Charge the battery in well-ventilated areas.
• Do not cover the battery and charger during charging.
• Charge only on dry and non-ammable surfaces.
IMPORTANT:
The battery must be fully charged at least every 2 months to avoid damage or
destruction of the cells.
If the charging time exceeds the usual charging time (see table), the battery may be
damaged. In this case, stop charging immediately and bring both the battery and the
charger to a dealer for a check.

15
Store the battery
If you do not use your e-bike for a long period, remove the battery, charge it (60-80%)
and store it in a dry place.
Warnings
• Check the charge level every 2 months and recharge if necessary.
• Store the battery in a place between -10 ° C and 35 ° C. Be aware that temperatures
around 45 ° C can be easily reached near the radiators and inside the vehicles left in
the sun.
• Avoid storing the battery in direct sunlight.
• To prevent the complete discharging, the battery will go into “sleep” mode after a
certain period.
• Do not expose the battery to temperatures lower than those allowed -10 ° c.
• If you notice that the battery becomes hot during use, during charging or during
storage or if it gives off a strong odor, changes its appearance or any other anomaly,
do not continue to use the battery but take it to a dealer for inspection before using it
again.
Battery wear
The battery has a life of about 700-800 recharge cycles.
As battery usage increases, battery capacity slowly decreases.
This also reduces the travel range of your e-bike and does not constitute a defect.
If the distance is still sufcient according to your needs, you can continue to use the
battery.
Battery life depends on various factors:
• Number of recharges (about 700/800 charge cycles).
• The age of the battery
• Storage and use conditions.
Obviously, the battery deteriorates and loses capacity even if it is not used. The life of
your battery may be affected by the following precautions:
• Charge the battery after each run even if it is a short journey. Lithium ion batteries
are not subject to memory effects.
• Avoid riding for long distances with high gears on high slopes with assistance at the
maximum level.

16
Disposal
If you replace parts of your e-bike, please take note of the local waste disposal
regulations. Used batteries and accumulators do not have to be disposed with normal
household waste.
Every consumer is required by law to dispose of used batteries at specic collection
points at a recycling center, a battery trading company, a specialist retailer or
manufacturer.
Batteries containing dangerous substances are marked with a symbol consisting of
a waste bin and the chemical symbol (Cd, Hg or Pb) of heavy materials, which are
responsible for their classication as pollutant.
For more information, please contact your local waste disposal service or your
municipal administration.
Exhausted batteries, accumulators with LEDs, NiMH (nickel metal hydride) or lithium
ion technology are to be considered dangerous goods
Lithium-ion batteries must be insulated in each pole with insulating tape to prevent
short circuits and potential dangerous reactions.
During the transport or the transfer of the exhausted batteries to the waste disposal
facilities, the ADR regulations (regulation for the transport of dangerous goods) have
to be applied.
In compliance with the European Directive 2006/66 / EC, defective or used batteries
must not be used, and according to the European directives 2002/96 / EC, electrical
equipment that can no longer be used must be collected separately and recycled in
an environmentally friendly way respecting the environment.
The drive unit, the battery, the display, the control element, the accessories and the
packaging must be recycled in an environmentally friendly manner.
Do not dispose electronic drive components with household waste.
