3.2 T chnical f atur s
The FreeDuck2 Wheel is an innovative ike propulsion system that integrates all the electrical and mechanical devices necessary for its
operation and ena les any traditional icycle to e transformed into a pedal assist ike.
The wheel adapts to all icycles with: standard IS2000 mount, 135 mm-wide fork (recommended value) and VBrake rakes.
The electric motor provides assistance proportionally to the force exerted on the pedals, which is detected thanks to a sophisticated
com ined torque/speed sensor. This way, the motor will provide more assistance when needed, for example with standing starts or riding
uphill, guaranteeing a smooth and relaxing ride.
When in pedal-assist mode (see Par. 7.1 on p.10), motor performance is limited to a top speed of 25 km/h and 250W of power, as
prescri ed y Electrically assisted ike standards. It is still possi le to reach a higher speed, ut the power required to do so relies
exclusively on the rider's muscle strength.
The e-wheel can e controlled through a smartphone app that communicates via Bluetooth. Consult the reference manual.
The icycle on which the device is mounted can also e used as a traditional ike simply y keeping the device turned off.
3.3 T chnical data
Rim size 26” or 700c Battery type Li-ion
Motor type Brushless Rated voltage 36 V
Motor continuous power 250 W Battery capacity 11.8 Ah
Top speed in pedal-assist mode 25 Km/h Energy management system BMS with equaliser
Operating temperature 0°/ 50°C* Total charging time 4.5 hours
Notes: * battery and motor performance deteriorate quickly when used outside this temperature range. As such, use in these conditions is
not recommended. When the inside temperature of the e-wheel is below -20°C or above 60°C, system operation is inhibited.
The FreeDUCk2 Wheel can e used to create a pedal assist icycle in compliance with UN EN 15194 and 168/2013/EC standards.

4 MOUNTING THE E-WHEEL ON THE FRAME
Mounting the e-wheel on the frame is quick and easy.
Place the e-wheel in the ack fork slot (point 1) - the power utton and the charger
connector must e on the left and the direction arrow shown in point 2 must e facing
forward.
Make sure that the rotation stopper (point 3) is perfectly inserted in the slot.
If you need to adjust the position of the stopper ecause of the way the fork is
turned or to prevent the frame from eing in the way of the e-wheel parts (e.g.
utton or connector), unscrew the 12 Torx M4 screws of the flange and turn the
stopper as needed using a 10mm spanner. Once adjusted, lock the screws with a
2.8 Nm tightening torque.
The direction arrow (point 1) must always face forwards, with a ±15° maximum
tolerance.

6
Screw on the two axle nuts and position the e-wheel parallel to the frame so that the
chain has a 15-20 mm stroke at the centre.
Correct adjustment is necessary to prevent the earings and transmission organs from
premature wear.
Check the alignment of the wheel again (adjust if needed) and tighten the nuts to a
30Nm torque using a 14mm spanner.
Once assem led, lu ricate the transmission with chain grease.
• Riding with a wheel that has not een properly installed is very dangerous. Use suita le tools in good condition for
tightening. Respect the tightening torques indicated.

5 ADJUSTMENTS AND CHECKS BEFORE USE
Before turning the e-wheel on for the first time, carry out the following adjustments and checks.
5.1 Pr liminary ch cks
♦ Fully charg the attery. Please refer to the instructions in Par.6.3 on p.8.
♦ Make sure the tyr pr ssur is 5.5 ars. Correct tyre pressure is essential on electric vehicles to guarantee maximum range for
each charge and a long attery life.
6 BATTERY
6.1 G n ral batt ry information
FreeDuck2 wheels are powered y a sophisticated Li-ion attery. This innovative technology guarantees great range, relia ility and
dura ility.
The complete attery - composed of different elements connected in series - has a rated voltage of 36 Volt.
The BMS (Battery Management System) is the electronic device that manages and protects the attery from undercharging, over voltage
and overheating during charging and while in use.
In addition, the voltage of attery elements is levelled y an equalisation system that intervenes during the final charging phase. We,
therefore, recommend charging the attery for an extra hour after it is fully charged (5.5 hours total) at least once every two weeks.
The attery, BMS and equaliser are all positioned inside the e-wheel and do not require manual maintenance.
The attery has no memory effect and can e charged at any time even if partially charged.
Battery performance refers to a temperature of 20°C. For each degree elow this, there will e a 1% drop in performance. This means that
if the temperature is 0°, a 20% reduction in range is to e expected.
• Any operations or changes to the electrical devices of the e-wheel not expressly approved by DUCATI Energia shall
invalidate the warranty.

8
6.2 Corr ct batt ry manag m nt
The new e-wheel is usually supplied with a 50% charge, so the attery must b fully charg d b for using it for th first tim .
At the eginning, lithium atteries go through a "training" process, which affects future performance and dura ility. Do not fully discharge
the attery during the first 4/5 cycles and do not put the vehicle on which it is mounted under too much strain.
To o tain maximum attery performance and maintain its features over time, please adhere to the following instructions:
 Fully discharging the attery must e an exceptional event, not the norm. Avoid further discharging the attery once the red light
comes on (see Par. 6.3).
 The attery must not e left flat for long periods of time, charge it as soon as possi le, in any case within 24 hours.
 If you plan on not using the e-wheel for a long time, store it away from the elements and extreme temperatures and fully charge
the attery at least once a month.
6.3 Charging th batt ry
The attery level is indicated y the light around the power utton. Each colour corresponds
to a different level:
COLOUR REMAINING CHARGE
GREEN a ove 60%
YELLOW etween 30 and 60%
RED etween 15 and 30%
FLASHING RED elow 15%
Note: If the light flashes red at high frequency, the attery switched into protection mode. Turn
off the wheel, wait some time and then turn it ack on.
During the first couple of uses, the light may flash red even after charging. This is due to the BMS self-learning phase, after which the
correct level will e shown.

FreeDUCk2 Wheel Manual Rev. 2/2015 - reproduction is prohi ited 9
Charging the attery is very easy:
 Put the vehicle in a sheltered environment on a sta le support.
 Turn the e-wheel off.
 Wait a few seconds, then connect the charger to the e-wheel.
 Connect the plug to a normal 220V socket.
While charging, the colour of the light on the e-wheel will indicate the level reached. Once
charged, disconnect the charger first from the mains, and then from the e-wheel.
6.4 Charg r
A Status indicator light
B Fuse
C Charging connector
D Plug
The charger is fitted with only one warning light ("A"), which glows green to indicate the
presence of the power supply (220V) when the plug ("D") is plugged in.
The warning light turns red during the charging process, when even the connector ("C") is
connected to the wheel. It turns ack green at the end of charge.
If the warning light "A" does not come on after connecting the charger to the e-wheel, make sure the socket is indeed connected and
working. If so, fuse "B" might e lown and need replacement.
If the fuse needs to be replaced, use one with the same amperage. Using the wrong amperage can lead to serious risks,
including fire hazard.
LEDS 1

10
The charger must e used sheltered from the elements and not exposed to direct sunlight.
Do not cover the charger when functioning, as doing so will impede cooling and cause damage.
If the internal temperature of the e-wheel is a ove 45°C (due to exposure to sunlight or intensive use), the attery cannot e charged until
the temperature drops elow this threshold.
• Charging the battery with any device that is not the original charger supplied by DUCATI Energia, and connecting any
unauthorised electrical devices to the e-wheel circuits or its charger can result in serious material and personal damage
and cause a fire.
• Do not use the charger or the cables if they look damaged. The voltage inside the device is dangerous when in use.
7 USING A BICYCLE WITH FREEDUCK2 WHEEL
The FreeDUCk2 wheel is designed for easy use. The icycle on which it is mounted can e used oth in pedal-assist mode or as a
traditional ike y simply keeping the e-wheel turned off.
7.1 P dal assist mod
In this mode, the electric motor assists pedalling, so cycling is easy and relaxing.
The power supplied y the motor is proportional to the force exerted on the pedals (com ined torque-speed sensor), so riding is smooth
even when going uphill and starting and stopping continuously, as is the case in city traffic.
The motor supplies up to 250 W power and a speed of 25 km/h, as per the European
standards concerning the operation of pedal assist ikes. In case of higher power demand
(such as facing a very tough clim ) or travelling at speeds a ove 25 km/h the engine stalls.
To activate pedal assist mode, keep the power utton pressed for a few seconds. A light will
flash and show the colour corresponding to the attery level (see Par. 6.3 p.8).
Once finished, remem er to switch off the e-wheel y pressing the same utton.

FreeDUCk2 Wheel Manual Rev. 2/2015 - reproduction is prohi ited 11
• It is important to switch the e-wheel off when not using the vehicle to avoid consuming energy. In any case the e-wheel
will turn off automatically after some hours of no pedalling.
• If the e-wheel is subjected to prolonged strain at high temperatures, the thermal protection may trip, inhibiting motor
function if the internal temperature rises above 60°C. If the protection trips, turn off the bike and wait for the system to
cool down.
7.2 Unassist d p dalling
To use the icycle in this mode, simply turn off the e-wheel.
Riding will e similar to a traditional icycle. If you use the ike in this mode for a long time, make sure to charge the attery at least once
every two weeks.
The attery undergoes a slow self-discharging process which could lead to a progressive deterioration and loss of capacity if left
uncharged over a long period of time.
8 MAINTENANCE
Little maintenance is needed, ut the simple rules descri ed in this chapter must e followed carefully to avoid performance deterioration.
 Tyr
The correct pressure is 5.5 ar. Lower pressure can lead to a significant increase in energy consumption, thus reducing the range of the
vehicle. Pressure set y the manufacturer must also e maintained in the front tyre.
 Batt ry
Prevent the attery from discharging completely and never leave it flat for long periods of time. Charge for a minimum of 5.5 hours at
least once every two weeks to allow it to equalise.
9 STORAGE FOR LONG PERIODS
If you are storing the e-wheel for long periods of time, please refer to the following indications:
 Before storing, fully charge the attery and charge again at least once a month.
 Store it in a sheltered, cool and dry place.
 If mounted on a icycle, store raised from the ground to avoid deforming the tyre.

12
10 WASHING AND CLEANING
Periodical cleaning helps maintain the icycle in a good and efficient state, ena les correct maintenance and makes it easier to notice
damage or reakage. To wash the icycle correctly:
 Do not use high pressure or high temperature jets, ut only water, mild detergent and soft,
natural sponges.
 Do not use aggressive detergents, solvents or a rasive pastes that could severely damage
varnished frame or chrome parts.
 After washing rinse the icycle with cold, clean, low-pressure water and dry it thoroughly.
 Lu ricate the transmission after every wash.
 To remove ru er rake residues on the rims, use a rag soaked with the specific gentle solvents
sold in spare part and accessory stores.
• Wet brakes extend braking distances. After washing the bicycle, ride slowly until the brakes are completely dry.
11 WARRANTY CONDITIONS
Warranty conditions are descri ed in the "Warranty Certificate" provided. The "Warranty Certificate" must e kept for the entire warranty
period and, if servicing is requested, it must e given to the dealer. Following the installation and operating instructions in this Manual is an
essential condition for the warranty to remain valid.
