preface
Dear customers and cycling fans!
From now on, your cycling experience will be enriched by a whole new dimension.
Thanks to our Austrian invention, previously inaccessible trails and destinations
are reachable at the mere touch of a button - and all within a healthy pulse range!
So now there’s nothing to stop you getting out for a leisurely, yet tness-enhancing,
bicycle ride with your partner or group of friends.
A bicycle should remain a wonderful piece of sport equipment. The functions and
handling characteristics of your bicycle do not change by the system. Because of the
small extra weight of less than 2 kilograms you can use the bicycle further without
reservation. From the outside you can only see the small button on the handlebars,
nothing else.
Please read these operating instructions carefully and keep the booklet for future
reference!
…RIDE ON(E)!
Your vivax assist Team
e-Drive for bicycles

2.1 Assembly
The vivax assist is an additional electric drive for bicycles, it supports your
own muscle power.
Propulsion is provided by an electric drive, the vivax assist gear box works
in combination with the bottom-bracket. The power supply comes from a
high performance battery, which is stowed away in the saddlebag. The
drive is activated by the push-button on the handlebar.

3.4 Adjusting the seat post
The electronic control is installed in the seat post. To avoid damages to the
electronics and the cables, the following points must be noted:
Attention!
• Nevertaketheseatpostcompletelyoutoftheseattube!Shoulda

insertion-deepness (10 cm). Never push it into the seat tube or
pull it out with violence. Re-lubricate the seat post. So you can adjust it
more simply and protect the electronics against water intake.
Never adjust the x-ring (14) – the warranty will be invalid.

3.5 Saddlebag
The saddlebag is an integral part of the vivax assist. The cables from the
electronic control to the battery / push button / speed senor run through the
bag.
Attention!
• Donotunfastenordetachthesaddlebagfromthemounting(cablescan
be damaged)!
• Should it be necessary to replace the saddlebag, before you dissemble it, all
of the socket connections must be disconnected and all of the cables -
together with the grommet - must be pulled out carefully, then remove it.

The vivax assist is activated by the push-button (1). The push-button switches
the motor on and off and also stores the pedal frequency.
4. operaTion anD programming
4.1 Switching the motor on / off
Switching on
Push the push-button for app. 1 second, the system will be activated with
the last stored pedal frequency.
Danger!
Only activate the drive while cycling.
If you switch the drive on with a raised rear wheel, the pedals and the rear
wheelwillbepropelledimmediately;dangerofinjury!
Switching off
A short activation of the push-button switches the drive off again.
The drive switches off automatically in the following situations:
• Brakingofthebicycle(NEVERabrupt),
• pedal frequency less than app. 15 revolutions per minute (the drive cannot
be started also),
• whenthebatteryisempty,

4.2 Storing the pedal frequency
The vivax assist supports you, when your own pedal frequency is lower
than the stored one. Therefore, store the pedal frequency while travelling
on level ground so that the drive can then be started with the desired set-
ting. You will attain the best assistance at a pedal frequency of app. 60-70
revolutions per minute. Pedal frequencies under 50 rpm or over 90 rpm
will not be stored. This function is similar to a kind of pedaling cadence
cruise control.
Pedal frequency storage process – to your individual frequency
• Switchoffthedrivetostore,
• cyclewiththerequiredpedalfrequency,
• keepthepush-buttonpressedformin.5tomax.10seconds;When

Pedal frequency storage process – to the highest frequency:
You store the highest pedal frequency
- while riding.
• Whenthedriveisoff,keepthepush-buttonpressedformin.10seconds.
- while stationary:
• Whenthedriveisoff,keepthepushbuttonpressedformin.10seconds
then keep the rear wheel raised.
After the memory procedure the system is activated. Press the push-button
again briey and the drive is switched off.

Note!
The pedal frequency will remain stored until the frequency is replaced
by a new one. If you pedal faster than the stored pedal frequency, you will

4.3 Cycling tips
• Pay attention to the safety information in this operating instructions and
the bicycle manufacturer’s instructions!
• Inordertoguaranteethebatterylastsforthedurationsofyourtour,only
use the drive when you feel you need it!
• Alwaysstarttocyclewiththedriveswitchedoff!Switchonthedrivewhen
you are safely riding. The vivax assist has no start-up-help.
• Toavoidunauthorizedoperationbyathirdperson,alwaysremovethe
battery when leaving the bicycle, e.g. during a break!
Note!
Note about outdoor transport by car / transport on car bike racks:
 Whenitrains,thebicycleisexposedtoverylargeamountsofwater.Protect
the electrical components, such as push-button, saddlebag and seat tube,
with a water-tight, wind-proof sheet.
Disconnect the battery and take it out of the saddle bag and transport it
separately in the car (also at transport in the car).
oPeration and Programming
Checking the stored pedal frequency:
While stationary:
• Activatethedrivewitharaisedrearwheelandlowestgear.
If you switch on the drive with a raised rear wheel, the pedals and the rear

5.1 Inspection
Plug connections in saddlebag are x: battery (bayonet xing), push-button
(6 pole. plug), plug of the speed limiter (3 pole. plug - only with blocking at
25 km/h)
Check cables and plugs. Damaged cables and connections must be
replaced immediately. Please contact your specialist dealer.
Inspect the saddlebag fastening for damages and mechanical security.
Check the saddlebag for tears and damage.
Control the battery charge.
Perform a function test.
After an accident, both the bicycle and the vivax assist should be inspected
 byanauthorizeddealer.
5.2 Maintenance
Never unfasten the motor mounting screw (16) on the seat tube!
Never disconnect the cables and plugs (except battery).
service and maintenance
5.3 Cleaning
Always remove the battery and close the saddlebag before cleaning, to
ensure the plugs are protected.
Only clean your bicycle with clear water and a sponge!
Never use a high-pressure cleaner or water jets. The electrical equipment
and electronics of the drive are not designed to cope with this!
Do not turn the bicycle upside down when you clean it.
