INTRODUCTION
The company Oxygen S.p.A. would like to thank you for your confidence in its products and congratulate you on your
purchase of the new electric LEPTON scooter.
This manual features all the main points you will need to know to look after your Lepton, get the best possible
performance out of it and prolong its service life cost effectively.
The Lepton has been designed for city use on roads only.
N.B.: Being a moped, the Lepton is not designed to carry passengers. The Lepton has a top speed of 45 Km/h (28
mph), and can be registered as a MOPED in some states.
WARNING:
oany work carried out on the scooter during the warranty period by any person other than
authorized OXYGEN S.P.A. personnel shall result in the warranty becoming void.
odon't forget your Lepton is very quiet when it runs, and bear this in mind when riding near other
vehicles and pedestrians.
Oxygen S.p.A. reserves the right to make any changes to its models at any time, though the essential features
described and illustrated herein shall remain unaltered. and therefore declines liability for any errors encountered in
the manual as a result of said changes.

GENERAL FEATURES
ELECTRIC MOTOR
Your Lepton scooter uses a three-phase brush-less permanent-magnet electric motor.
Apart from its high efficiency and low consumption this motor is also characterized by its compactness, lightness and
silent running and the fact is does not require routine maintenance.
DRIVE ELECTRONICS (FIG.1)
The heart of your Lepton scooter is its electronic drive and
management system (EDM) known as "DRIVE".
The system can be divided into the following functional
components:
1. Generation of auxiliary voltage, both internal and
external (ancillary equipment). The system taps the
external voltage originating from the traction battery unit
and supplies the following output voltage:
othe internal voltage required to run the hardware
properly
othe 12 V for the scooter's external ancillary
equipment. Fig. 1

2. Control of the brushless motor. The motor is controlled by means of the different physical value readings, i.e.:
ointernal sensors checking the intensity of the current delivered to the motor;
oexternal sensors checking the temperature status and condition of rotary parts, located in the motor.
In this regard, it is essential that there are no breaks in the signals-to-motor connection cable. Consequently,
if the user notices any damage to this cable, the vehicle must be checked by a service centre immediately or
the Warranty conditions shall become void.
3. Management of auxiliary signals to and from the drive regarding:
oAnti-theft device
oSpeed, operating status and diagnostics indicator device
oMonitoring of the battery charge status.
The advantages of the DRIVE lie in the high efficiency and low energy consumption, energy recovery during braking,
rpm management at constant speed, battery management and battery charge status check as well as the
management of the other auxiliary functions.
BATTERY CHARGER
The battery charger is the intermediary element between the power mains and the electric scooter. It transforms the
altemating voltage supplied by the mains into direct voltage.
There is a high-frequency battery charger built into the DRIVE of your Lepton.
It can be connected to any 220/240 Volt outlet.
The built-in battery charger is pragrammed for the automatic charging of the battery model used on Leptons only. The
battery charger cannot be used to recharge other battery types.

ELECTRIC BATTERY
There is a compartment under the footboard capable of housing four 38AH batteries connected in series.
VEHICLE MARKINGS (FIG. 2)
Frame number
The frame number is printed on a bracket welded in the
central part of the frame, on the right-hand side.In
accordance with the new internationalregulations, the
scooter must feature the VIN marking consisting in 17
alphanumeric characters essential for the vehicle's univocal
identification for 30 years.
The "type-approved plate" must be applied in the same
position, on the left-hand side.

INDIVIDUAL CONTROLS
CONTROLS ON THE LEFT HANDLEBAR (FIG. 5)
1) Horn
The horn sounds when the button is pressed .
2) Indicator switch .
Move the switch to the left " " to indicate you are
turning left; move the switch to the right " ",to indicate
you are turning right.
Return the switch to the centre to turn off the indicator.
3) Mode control.
This enables the programmed functions on the LCD strip of the
dashboard to be chosen in the following order:
oRemaining runtime (aut.) expressed in kilometres
and calculated based on the driving behaviour of the last 15 seconds.
oTotal distance covered (t.) in kilometres.
oPartial distance covered km.

oIn order to zeroize the latter function. keep the button pressed for 5 sec.
CONTROLS ON THE RIGHT HANDLEBAR (FIG. 6)
1) Light swltch
The lights come on when the switch is set to " " .
2) Standard drive mode control
This enables the scooter to be started ridden in normal mode
at a maximum speed of 45 km/h. The relevant indicator light on
the dashboard lights to advise that the control has been
switched on.
3) Sprint mode control
This enables the rider to shift from standard drive to sprint
mode when pressed for a few seconds.
This shift must be made whilst the scooter is powered and
enabled, but at a very low speed or at a standstill.
The relevant indicator light on the dashboard lights to advise
that the control has been switched on.
N.B.: the same conditions must be observed when returning to the standard drive mode.
