* The X35 internal battery is installed inside
the Gain downtube vertically. For that pur-
pose, internal batteries from MY2021 and
onwards feature two threaded holes on their
side for installation on 2021 Gain frames, be-
sides 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.

RANGE EXTENDER
The Range Extender from Ebikemotion provides an extra
208W/h to the main internal battery on Ebikemotion's X35
systems, increasing the 248W/h of the main battery up to
QTY.
a maximum capacity of as much as 450W/h.
This increase in total capacity of the system will make it
1
possible to increase the autonomy achieved with the inter-
nal battery by up to 70%.
HOW THE RANGE EXTENDER WORKS
The Range Extender works like a portable internal battery
charger that charges the main battery while it is turned on.
It operates differently from other systems in that on the
Ebikemotion X35, only the main battery provides power
to the motor, while the Range Extender charges the main
battery, regardless of whether the motor demands current
from the main battery or not (such as at speeds greater
than 25 km/h, when there is no pedaling or the bicycle
is not moving).
The Range Extender provides charge to the main battery
at a discharge ratio of 2A, while the motor can demand
current of up to 9A. Therefore, the Range Extender is not
capable of supplying enough current to the motor by itself,
and all this current comes from the main battery.
If the main battery is discharged and the Range Extender
is connected and turned on, you must wait until the Range
Extender has charged the main battery enough for the sys-
tem to provide electrical assistance. For this reason, it is
recommended that whenever you use the Range Extend-
er, always keep the unit connected to the main battery
through the charging port in order to make sure that the
ORBEA | 57
main battery charges during use, thus ensuring the max-
imum possible autonomy. In the case of intensive use of
the system in extreme cases, in the top assistance mode
during long periods of time, the battery may completely
discharge faster than the Range Extender is able to charge
it. In this case, you will need to wait for the main battery to
have enough charge from the Range Extender to be able
to continue riding with electrical assistance.
Acting as the main battery charger, the Range Extender
is compatible with any version of the Ebikemotion X35
system.
After connecting the Range Extender to the bicycle charg-
ing port, turn on the Range Extender by pressing the Iwoc
One button on the top of the unit. The light on the button
will turn white. To turn off the Range Extender, press and
hold the Iwoc One button for 2-3 seconds.

After turning on the Range Extender with the unit connect-
ed to the bicycle, the Iwoc One button on the top tube of
the bicycle will blink continuously in the color correspond-
ing to the current level of charge of the main battery, just
like when the charger is connected to the charging port.
