The anti-theft frame only offers temporary protection and little security,
as it does not keep your G4 at any fixed position.
For longer parking, improve security with an anti-theft chain, such as the
one delivered with your G4 or an anti-theft U-clamp.
G4 motor
Your G4 is supplied with a motor, which classes it under the category of Electric Bicycle
(EB). The legislation in effect on using an EB is likely to vary from one country to another, so
please refer to the legislation of the country in which you are using your G4.
The BROSE motor is composed of a battery with a capacity of 636 Wh, a Brose Drive S
motor and a display unit. It is supplied with a 4 A charger.
BROSE display unit
The BROSE display unit is situated to the left of the handlebar. It consists of 4 physical
buttons, a joystick to access different options and a screen, allowing various information to
be displayed. The 4 physical buttons allow the system to be tuned on and off, regulate the
assistance level from 0 to 4 and light up/extinguish the lights. The buttons to regulate the
level of assistance also allow activation of walking assistance. To activate walking
assistance, the level of assistance must be set to 1, 2, 3 or 4. It is then necessary to press
continuously on the +1 assistance button, in order to activate the motor to move the bike
forward at a speed up to 6 km/h.
Walking assistance must never be used while sitting on the bike. It should
only be used to assist the cyclist to push the bike under difficult
conditions, as when ascending a hill, for example. Walking assistance
should only be used when both hands are free to hold the handlebars and
must not impair governing the bike’s speed.
The joystick allows access to the menu (4 directions: left/right: up/down) and to validate the
settings (short central pressing). Here are the various menus available by turning the
joystick to the right:
- Menu 1: peddling power provided by the cyclist
- Menu 2: remaining autonomy (approximate calculation and indicative only)
- Menu 3: partial distance, average speed, max. speed, reset to 0
- Menu 4: total distance
- Menu 5: automatic lights, language, display position, unit of speed
- Menu 6: Bluetooth
A micro USB socket allows connection to a device, such as a Smartphone or GPS, in order
to recharge them, however the output current is limited to 0.5 A.
