Hub motor use and maintenance
- Our electric bicycle is programmed to start the pedal assistance after one complete revolution of pedalling
- Do not use the electric bicycle during a flood or storm. Do not immerse electrical parts in water as they could get damaged
- Avoid any type of impact with the hub motor, otherwise, the cover and aluminium body may break
- Frequently check the screws of the hub motor on both sides; tighten them if they are not fastened well
- The cable connection to the motor must be checked

Electric control unit maintenance
The electric control unit is located under the battery of our electric bicycle
It is very important to take care of the electrical components by following the guidelines below:
-Be careful to avoid water entering the control unit or immersing it into water as it could get damaged
-Take care to protect the control unit from strong shakes or blows
-The control unit should work normally at a temperature from -15°C to +40°C
PLEASE NOTE: Do not open the electric control unit. Any attempt to open the control unit, modify it or adjust it in a different
manner will void the warranty. Contact the retailer or an authorized technician to repair the bicycle.

Troubleshooting
Problem description
Possible causes
Troubleshooting
After turning on the battery power, the
motor does not assist pedalling
1) The motor cable is loose; 2) The
brake lever does not spring back well
and therefore maintains the power on the
“off” position;
3) The fuse of the battery
is broken; 4) The speed sensor is too far
from the magnetic ring on the bottom
bracket; 5) The connection between the
sensor and the control unit is loose or
not corrected correctly.
Firstly, check the battery is charged. If it is not, charge it.
1) Check the connection is fixed correctly. If it is loose,
firmly connect it. 2) Make sure the brake lever springs
back to the normal position, accurately, without braking;
3) Open the battery compartment and check if the fuse is
broken. If it is, contact your retailer or an authorized
technician to install a new one.
4) Adjust the distance
between the magnetic ring and the sensor, making sure
the distance between them is less than 3 mm; 5) Fix the
connection between the sensor and the control unit well.
The distance you travel on a charged
battery becomes shorter (Note: battery
performance is directly connected to the
weight of the cyclist and any other load,
to the wind, to road conditions and to
constant braking).
1) The charging duration is insufficient;
2) The environmental temperature is so
cold to influence the battery’s
functioning. 3) With a road with
different steepness, going against the
wind or on a road with poor conditions
4) Tyres have a pressure that is too low;
5) With very frequent braking and
starting. 6) The battery has not been
used for a long time.
1) Charge the battery by following the instructions; 2) In
winter or at 0°C, it is better to keep the battery in a
heated place (home); 3) It will go back to normal if
outdoor conditions are normal; 4) Inflate tyres making
sure they are inflated to 45psi; 5) No problem, it will go
back to normal when conditions improve; 6) Charge
frequently as described in this instruction manual
(Chapter 6) If the problem persists, contact the retailer.
After connecting the charger to the outlet,
the LED does not illuminate.
1)Problem with the outlet;
2)Weak contact between the outlet and
the charger; 3) The temperature is too
low.
1) Check and repair the outlet.
2) Check and re-insert the charger firmly into the outlet.
3) Charge in a warmer environment. If the problem
persists, contact the retailer.
After charging for 4 or 5 hours, the LED
indicator of the charger is still red and the
battery is still not fully charged (Note: It
is very important to charge the bicycle
according to the instructions in Chapter 7,
to avoid any problem or damage to the
bicycle.
1) The environmental temperature is
over 40°C
2) The environmental temperature is
below 0°C
3) After use, it is impossible to charge it,
then the battery is “
over-discharge
d”
.
4) The voltage of the outlet is too low to
charge the battery.
1) Charge the battery in an area below 40° C, or
according to the instructions in Chapter 7;
2) Charge the battery in a warmer area, or according to
the instructions in Chapter 7;
3) Keep the battery according to Chapter 6 to avoid
natural “o
ver-
discharge”
;
4) Do not charge when the outlet provides power lower
than 100V.
If the problem persists, contact the retailer.
