Operation

Start-up

Requirements

The eBike system can only be activated when the fol­lowing requirements are met:
– A sufficiently charged battery is inserted (see bat-

tery operating instructions).

– The speed sensor is connected properly (see drive

unit operating instructions).

Switching the eBike system on/off

The following options are available for switching on
the eBike system:
– Press the on/off button (2) of the on-board com-

puter with the eBike battery inserted.

– Press the on/off button of the eBike battery (see

battery operating instructions).

The drive is activated as soon as you start pedaling
(except for in the push assistance function or with the
assistance level OFF). The motor output depends on
which assistance level is set on the on-board com­puter.

As soon as you stop pedaling when in normal opera­tion, or as soon as you have reached a speed of
20mph, the eBike drive unit switches off the assis­tance. The drive is automatically re-activated as soon
you start pedaling again and the speed is below
20mph.

The following options are available for switching off
the eBike system:

– Press the on/off button (2) of the on-board com-

puter.

– Switch off the eBike battery using its on/off button

(some bicycle manufacturer-specific solutions pre­vent access to the battery on/off button; see the bi­cycle manufacturer operating instructions).

The system shuts down after being switched off; this
takes approximately threeseconds. It cannot be

switched back on until shutdown has been com­pleted.

If the eBike is not moved for approx. ten minutes and
no button is pressed on the on-board computer, the
eBike system switches off automatically in order to
save energy.

Note: Always switch off the eBike system when you
park the eBike.

Note: If the battery of the SmartphoneHub is empty,
you can still switch on your eBike using the eBike bat­tery. The SmartphoneHub battery begins charging au­tomatically once the eBike battery is switched on. Al­ternatively, the battery of the SmartphoneHub can be
charged via the USB port.

Linking the SmartphoneHub with a smartphone

You can expand the indicators and functions of the
SmartphoneHub using the COBI.Bike smartphone
app. This app can be downloaded free of charge from
the AppStore (for Apple iPhones) or from the Google
Play Store (for Android devices).

To connect your SmartphoneHub with the smart­phone, open the COBI.Bike app on your smartphone
and follow the instructions in the app.

Inserting a smartphone into the universal holder

A universal holder(16) is supplied for attaching a
smartphone. Specific holders for iPhones can be pur­chased from the range of accessories. No separate
power supply is necessary for an iPhone holder.

For the universal holder, the power (5V/1A,
max.1.5A) is supplied using a separate USB cable
(included with delivery) via the microA/B USB port of
the SmartphoneHub.

necessary, remove the USB cable for the power sup­ply.

Software update

If a software update is available for the Smartphone­Hub, an indicator is shown in the smartphone app.
Follow the instructions in the app to perform the up­date.

Recovering the SmartphoneHub

A recovery operation should be carried out on the
SmartphoneHub if it is no longer functioning cor­rectly. To do this, open the app on your smartphone
and follow the instructions.

Power supply for the SmartphoneHub

The SmartphoneHub has an internal lithium-ion poly­mer battery (nominal/minimum 300mAh, 3.7V) that
cannot be removed.

The SmartphoneHub can be switched on via its on/off
button(2) or via the on/off button of the eBike bat­tery. If the SmartphoneHub cannot be switched on, it
must be charged via a USB cable for at least 30min­utes.

Switching the push assistance on/off

The push assistance aids you when pushing your
eBike. The speed of this function depends on the se­lected gear and can reach a maximum of 3.7mph.
The lower the selected gear, the lower the speed of
the push assistance function (at full power).

u The push assistance function must only be used

when pushing the eBike. There is a risk of injury if
the wheels of the eBike are not in contact with the
ground while using the push assistance.

To activate the push assistance, briefly press the
WALK button on your operating unit. After activation,
press the + button within three seconds and keep it
pressed. The eBike drive is switched on.

Note: The push assistance cannot be activated at as­sistance level OFF.

The push assistance is switched off as soon as one of
the following occurs:
– You release the +button;

– the wheels of the eBike are locked (e.g. by applying

the brakes or hitting an obstacle);

– the speed exceeds 3.7mph.
The push assistance function is subject to local regu-

lations; the way it works may therefore differ from the
description above. It can also be deactivated.

Setting the assistance level

On the operating unit (15), you can set the level of as­sistance you want the eBike drive to provide you with
while pedalling. The assistance level can be changed
at any time, even while cycling.

Note: In some models, the assistance level may be
preset and cannot be changed. There may also be
fewer assistance levels available than stated here.

The following assistance levels are available as a max­imum:
– OFF: Motor assistance is switched off. The eBike

can just be moved by pedaling, as with a normal bi­cycle. The push assistance cannot be activated at
this assistance level.

– ECO: Effective assistance with maximum efficiency,

for maximum range

– TOUR: Steady assistance, long range for touring
– SPORT/eMTB:

SPORT: Powerful assistance, for mountain biking
and for cycling in urban traffic
eMTB: Optimum assistance whatever the terrain,
rapid acceleration when starting from a standstill,
improved dynamics, top performance (eMTB is
only available in combination with drive units
BDU250P CX, BDU365, BDU450 CX and
BDU480CX. This also requires a software update.)

– TURBO: Maximum assistance even at high pedaling

speeds, for biking sports

To increase the assistance level, press the + (14)
button on the operating unit repeatedly until the de-

Displays and settings of the SmartphoneHub

The SmartphoneHub is connected to the drive unit via
a cable.

The smartphone is mechanically connected to the
SmartphoneHub via a smartphone attachment.

The communication between the SmartphoneHub
and smartphone takes place via Bluetooth®.

The SmartphoneHub has a scratch-resistant 1.52"
