2.5 Other provisions
The first thing to do when starting use is to check the presence and integrity of the protections and the operation of the
safety devices. If you find any defects, do not use the pedal-assisted bicycle!
2.6 Unpacking and tuning
The pedal-assisted bicycle is delivered fully assembled and working.
2.6.1 Saddle adjustment
The adjustment of the height of the saddle is an essential prerogative for the correct use of the pedal-assisted bicycle.
Incorrect adjustment can generate structural breaks to the frame.
Adjust the height of the saddle by operating the quick release mechanism (Ref. A – Figure 1). Check that the mechanism
is tightened before testing the seat and using the medium. Do not lift the saddle beyond the limit sign placed in the tube
(Ref. B – Figure 1).
DANGER

3. BICYCLE DESCRIPTION
3.1 General description
The pedal-assisted bicycle is designed and built to be used outdoors, on roads and private or public environments. In
particular, the components and the type of pedal-assisted bicycle allow you to tackle routes with asphalt surfaces or
with similar characteristics without particular roughness.
The pedal-assisted bicycle is equipped with a rechargeable battery and an electric motor, whose intervention takes place
only in conjunction with the pedaling and gradually stops as the speed of the vehicle approaches 25 km / h, and then stops
completely at that speed.
For the management of the assistance system there is a special display located on the left side of the handlebar. On the
right side of the handlebar there is a control system for adjusting the gears.
INCORRECT AND UNINTENDED USE
The bicycle has been designed and manufactured for the specified use; a different use and failure to comply with the technical
parameters set by the manufacturer may constitute a dangerous condition for users.

3.3 Brake levers
The brake levers (Ref. F – Figure 5) are placed on the handlebars of the pedal-assisted bicycle, near the knobs (Ref. G – Fig-
ure 5). These systems make it possible to control the calipers of the disc brakes located near the wheel hubs. The right le-
ver controls the rear brake, the left one the front brake; the braking action is proportional to the force applied on the lever.
3.4 Speed change
The pedal-assisted bicycle has an 8-speed gearbox with the sprockets positioned on the rear wheel hub and selectable
by means of the opposing levers located at the base of the right knob. The indicator (Ref. H – Figure 5) presents at the bot-
tom of the handlebar allows you to view the selected ratio.

3.5.2 System ignition/shutdown
To activate the system you must first turn on the battery; after that, press and hold the on/off button. (Ref. L - Figure 6). To
turn off the system, press and hold the on/off button (Ref. L - Figure 6).
3.5 Assistance system management
3.5.1 Commands
To manage the assistance system there is a display on the left side of the handlebar. This device allows you to vary the
level of assistance and to view information regarding the path and status of the battery (Figure 6).

The two values are automatically toggled on the display.
6 - Error (see section 3.5.9 for error codes).
3.5.3 Assistance activation
The engine is activated and deactivated immediately if the pedaling stops. The power of the motor depends on the force
imposed on the pedals according to a multiplicative factor depending on the level of assistance selected.
Press and release the power button (Ref. L - Figure 6) to increase the level of assistance. To decrease the level of assis-
tance press and release the “-” button (Ref. M - Figure 6). The level of assistance can be selected from any screen of the
display
3.5.4 Assistance level
LEVEL 0 - NO ASSISTANCE
LEVEL 1 – ASSISTANCE 12,5%
Recommended route: plain - long distances
LEVEL 2 - ASSISTANCE 25%
Recommended route: plain/hilly - medium-long distances
LEVEL 3 - ASSISTANCE 50%
Recommended route: hilly /medium climb - medium distances
LEVEL 4 – ASSISTANCE 75%
Recommended route: ascent - medium short distances
LEVEL 5 - ASSISTANCE 100%
Recommended route: challenging
The power of the engine depends on the force imprinted on
the pedals according to a multiplicative factor according to
the selected level of assistance. The assistance drops linearly
until it reaches 25 km/h. Once this speed has been exceeded,
the assistance is automatically deactivated.

3.5.5 Single distance reset
With the device turned on, press the power button and the “-” button (Ref. L,M - Figure 7.1) at the same time to reset the single
distance (TRIP).
3.5.6 Walking assistance mode
The pedal-assisted bicycle is equipped with the function of walking assistance. This function allows you to move the bike
more easily during manual movement in case you face mall climbs.
In flat routes it is useful for starting the ride, up to a speed of 6 km / h.
To activate the above mode, turn on the assistance system using the appropriate button (Ref. L - Figure 7.1).
At this point, set the assistance level to 0 and press the lever (Ref. N - Figure 7.1) to activate the walking assistance mode.
Once the lever is released, the assistance mode is automatically deactivated.

maintenance actions or when you want to store the vehicle.
3.6.1 Battery charge status
You can view the battery charge status directly on the assistance
system management display.
In case that the battery is disassembled from the vehicle or you want
to see the state of charge without turning on the assistance system,
in the upper part of the battery there is a button (Ref.O – Figure 8) that
allows, through a LED light of different colors (Ref. P – Figure 8), to
display the state of charge.
CHARGING STATUS LED:
RED LIGHT 0– 25%
GREEN LIGHT 25- 75%
BLUE LIGHT 75– 100%
FIG. 8
3.6.2 Battery removal / installation
To remove the battery make sure that both the assistance system and the battery are turned off and proceed as it follows:
1. Insert the battery lock/unlock key into the battery lock at the top right of the frame near the handlebar and turn the keys
clockwise. (Ref. Q – Figure 9)
2. Holding the key rotated, unhook the battery and lift it (Ref. 2 – Figure 9)
3. Take out the battery completely, taking care not to hit the frame.
