Read the X35 system Use Warnings section
of this manual to know the correct installa-
tion instructions for the rear wheel, cables,
PASS sensor and rear rotor.
Always follow the recommended torque set-
tings for all the components on your bicycle.
The removal and installation of the X35
system components may require to remove
and install several mayor components of
the bicycle, such as the fork, the chainset
and bottom bracket, and may therefore be
beyond the mechanical knowledge of most
users. Always take your bicycle to an author-

placement of these components.
The incorrect installation of the bicycle
components may be cause of accidents and
serious injuries, as well as cause damage to
the components that may not be covered by
the warranty.
Always take the necessary precautions
when working with electric components to
avoid electric shocks and damage to the
components.
Connect all components in the correct way
to avoid short circuits and exposure to
elements.
Cover any crimped cable connections
(if there were any) with heat shrink tubing
or electrical tape to avoid short circuits.

LIGHTS CABLE INSTALLATION
The installation and replacement of the lights cable
requires the removal of the internal battery and must be
performed by an Authorized Orbea dealer.
Read the Lights section of this manual to know about the
lights cable routing on Gain.
REPLACING THE X35 INTERNAL BATTERY
Replacing the X35 internal battery is a process that
requires advanced mechanical knowledge for its correct
installation.
The bicycle fork, chainset and bottom bracket need to be
removed and all the pedelec system components discon-
nected.
Replacing the X35 internal battery is a process that must
be performed by an authorized Orbea dealer.
The X35 internal battery on your Orbea bicycle carries all
the relevant information about your bike, such as the serial
number and the specific motor maps for your model.
If the internal battery needs to be replaced due to natural
wear or a warranty claim, contact your authorized Orbea
dealer, who will provide Orbea with your bicycle informa-
tion and carry out the claim and installation.
The X35 internal battery is installed inside the
Gain downtube vertically. For that purpose,
internal batteries from MY2021 and onwards
feature two threaded holes on their side for
installation on 2021 Gain frames, besides the
three holes on its bottom side for installation
on pre2021 Gain frames.
Batteries from MY2021 are compatible with
pre2021 Gain, Optima and eMX24 frames.
However, pre2021 batteries are not compati-
ble with MY2021 and onwards frames.
