Note about this printed manual
Congratulations on the purchase of your bikespeed RS. You are holding
the original manual for the bikespeed RS and bikespeed RSc for Bosch
mid mounted motors in your hands.
Printed manuals may not be up to date for technical, logistical, and
economic reasons. This applies, for example, to the listed compatible
motors, displays and model years. You can find a current version of the
manual for download on our homepage (https://www.bikespeed.de) If
you are unsure, please feel free to contact us.
Product description
The bikespeed RS is a simple and compact kit to bypass the speed limit of
25 km/h of bikes with Sachs RS mid design. The installation is completely
invisible.
The bikespeed RS is also available in a customizable version, called
bikespeed RSc (custom). You can find more information about this on
page 13 of this manual. For the sake of simplicity and a better overview,
the bikespeed RSc is the same as the bikespeed RS except for the
personalization and therefore only the term bikespeed RS is used in these
instructions.
In contrast to other commercial tuning kits for pedelecs the bikespeed RS
displays the "real" speed on the tachometer instead of the half value. The
data of the cycled distance, average/maximum speed, calculated range, ...
are usable without any limitations. The levels of support as well as any
special profile will be certainly maintained. Light activation is also

page 3
unnecessary, and you can use the tuning if you have an additional lighting
system powered by the battery.
The tuning makes the final speed void, that means the terminal velocity is
only limited by the power of the drive and the muscular strength
invested.
We designed the installation as simple as we could. All the necessary
connections are pluggable and consequently they can be removed
without any traces.
Deactivation of the speed limit at 25 km/h is possible with the help of a
key sequence on the actuator (see page 9, paragraph “description of
functions”).
The tuning will adapt to your pedelec when it is activated. During this
process the drive, the display and the size of the tires will be recognized
automatically. The tuning is thus universally applicable, and you do not
have to adjust anything.

Safety instructions, product liability and
exclusion of liability
By using the bikespeed RS on your pedelec, a relevant safety feature (the
speed dependent limitation of the motor power) is overridden. You must
assume that your pedelec is not suitable for this and e.g., frame, brakes,
chassis, tires, etc. are not designed for the higher speed. The conversion
must be carried out by a specialist (e.g., the manufacturer of the pedelec
or an authorized specialist workshop) who will also check other
components on your pedelec accordingly and convert them if necessary.
Tuning an ordinary pedelec with a maximum speed of 25 km/h is not
recommended for the ordinary user, as S pedelecs are intended for
reaching higher speeds with the corresponding legal requirements, in
particular the approval of the Federal Motor Transport Authority of your
country (in Germany KBA/Kraftfahrtbundesamt).
We have not been able to conclusively clarify whether operation with the
bikespeed RS installed but deactivated is permitted on public roads.
Therefore, we expressly point out that the mere presence of the tuning
can constitute an offence in the sense of the Road traffic regulations or
riding without insurance, §6 Compulsory Insurance Act!

page 6
A modified bicycle may only be used by an authorized, trained and
instructed person. We assume the following level of training:
Function
User
Operator
Only persons trained and instructed
about
the special dangers
Maintenance personnel
/ technicians
Only the manufacturer of the pedelec or an
authorized specialist workshop by persons
with the appropriate expertise
Trainees or apprentices
the use is prohibited
General public
the use is prohibited
Trained users should be made aware of the increased risk when using the
modified pedelec:
Increased risk of impact Due to the increased speed, obstacles are
reached more quickly, and reaction time may not be sufficient to brake or
swerve in time.
Increased braking distance The increased speed also increases the
braking distance. Furthermore, it must be checked before use whether
the installed brake system is designed for the increased speed.
Increased risk of discomfort / neurological disorders Due to the
increased speed, vibrations can increase, which can lead to discomfort.
Furthermore, due to the increased speed, more concentration is required
from the user. This can lead to increased stress during use. Therefore,
only persons who do not have any physical, mental, or neurological
disorders may be users.
Possible loss of control The increased speed can make it easier to lose
control of the pedelec. The user must therefore be of age and equipped

page 7
with suitable protective clothing (helmet, protectors, etc.) to be
adequately protected from injury in the event of a fall.
Modified bicycles may only be used on fenced private property.
Furthermore, it must be ensured before use that there is sufficient space
to obstacles on the route. (e.g., stones, trees, water areas, etc.).
No other persons are allowed on the fenced off area during use and
precautions must be taken to ensure that no other person can enter the
area during use.
The converted pedelec must be equipped with a warning notice that is
clearly visible before the pedelec is used. The warning notice must
prohibit the use by untrained persons and outside the fenced private
area.
Operation on public roads is expressly prohibited by the Road traffic
regulations!
The bikespeed RS is installed and operated at your own responsibility;
any liability for damage or consequential damage, as well as legal
consequences for bikespeed or the manufacturer of the pedelec are
excluded in any case.
Before using the system, please enquire about the legal consequences
that may arise for you because of the installation.
We expressly point out that the use of bikespeed RS will result in the loss
of the manufacturer's warranty. Furthermore, the manufacturer and
bikespeed have no product liability for your pedelec.

page 8
Bikespeed or the manufacturer of your pedelec cannot guarantee that
brakes, frame, chassis, tires, etc. are designed for the use of the tuning
part.
Before use, the more highly stressed components of the pedelec (e.g.,
frame, brakes, tires, bearings, and suspension, etc.) must be tuned by the
manufacturer or tested and approved by a suitable testing Centre (e.g.,
TÜV or Dekra). If the speed is doubled, it must be considered that the
acting forces are quadrupled. In accordance with EN 15194, it must
therefore be checked that the modified pedelec still meets the
requirements. It is to be assumed that the higher stress is permanently
given.
If a component of the pedelec cannot withstand the higher stress, it must
be upgraded by the manufacturer of the pedelec or by an authorized
specialist workshop, or the bikespeed RS must not be installed.

Description of functions
The bikespeed RS removes the limit at 25 km/h of your pedelec. All other
features and functions of your bike remain as usual. This also includes the
protective measures installed by the manufacturer (e.g., short circuit,
overcurrent, power, torque, temperature, etc.), except for the safety
device for limiting the maximum speed.
After activating your pedelec the display will show an animation of the
battery’s capacity on your Sigma Remote. If the capacity runs from empty
(1 bar) to full (5 bars) your pedelec will support you with motor power
even if you exceed 25 km/h. If the capacity runs from full to empty the
support will end at 25 km/h.
To switch on or off the support above 25 km/h please change the level of
support down, up, down, and up again. If the procedure was successful,
you will see the animation of the battery’s capacity once more just like
when you activate your pedelec and this way you are informed about the
current setting.
Here is an example beginning on the level 3 bars:
Pushbutton down (new level: 2 bars)
Pushbutton up (new level: 3 bars)
Pushbutton down (new level: 2 bars)
Pushbutton up (new level: 3 bars)
If you have a bikespeed RSc you use the combination you chose
beforehand. (see page 13, paragraph „Description of the custom variant“)

page 10
Please enter the combination quickly without a pause of 3 seconds
between two keys. Repeat the procedure, if necessary, to obtain the
desired setting.
Hint A switched off bikespeed RS cannot be switched on with the
combination for service mode (see on page 11)!
Hint for the odometer
Please note that after the deinstallation of the bikespeed RS your
odometer may show a lower value under certain circumstances like you
are traveled with your bike. This behavior is caused by the design and not
a fault.
Please note this primarily when selling your bike.

page 11
Important hint when visiting the repair-shop or
software-updates on your pedelec
If you have in mind to update your pedelec software or wish to perform
the Sachs system with a customer service, please have a look on
bikespeed and check on our website www.bikespeed.de, whether the
tuning continues to work with a later software or not.
For a software update to your Sachs or Sigma system you have to
uninstall the bikespeed RS. Alternatively, there is the service mode on the
bikespeed RS that needs to be activated at your retailer.
Therefore, change the level of support 3x down and then 3x up. Please
enter the combination continuous without a pause longer than 3 seconds
between two keys. Begin on the highest level. In case of success the
entire battery index will blink 3x and meanwhile the software version of
the bikespeed RS will be shown on the speed indicator. Now the tuning is
in service mode and maintenance as well as software updating can be
executed.
Please note that the software version as just described is only displayed
correctly if you have set the display in metric units and therefore km/h.
If you have a bikespeed RSc you use the combination you chose
beforehand. (see page 13, paragraph „Description of the custom variant“)
This state is maintained even after deactivating the system. That is why
there will not be an animation of the battery’s capacity informing about
the state of the tuning.

page 12
For the deactivation of the service mode please use the same key
combination as for the activation or the combination you chose for
activating and deactivating the tuning. Please keep in mind that in
service mode the support of the drive ends at 25 km/h.
Hints
If you are not sure, whether the service mode is activated,
please uninstall the bikespeed RS before you update!
Please activate the service mode only for updates on your
pedelec!
A switched off bikespeed RS cannot be switched on again with
the combination for service mode!
After activating the service mode, we recommend switching off the bike
without moving it again. If a speed is displayed it could change the trip,
avg or max speed.

Description of the custom-variant (bikespeed-
RSc)
After many requests of our customers, we offer a new feature of the
bikespeed RS additionally. The individual customer configuration gives
you the opportunity with you selectable personal setting to protect your
tuning for discovering.
With your individual key combination, you can decide if the tuning should
be displayed its status with an animation above the battery indicator or
not. The tuning can be switched on/off at any time and you can control
the behavior (tuning on/off) after on switching your bike.
The configuration options can be found in the shop on our website. There
all possibilities are described with many tips and videos.
If you are interested to upgrade your standard bikespeed RS on a custom
version, you can feel free to contact us.

Keep in mind you have to switch the
stages to enter the combination.
Please start in a sufficient high or low
stage.
Please enter the combination continuous
with a pause from one to three seconds
between two keystrokes.
In our experience, the cause for problems most often are connectors
which are not correctly plugged in. Therefore, please always check if they
are set correctly and plugged in the correct socket. Please insert the
connectors as far as you cannot see the seals anymore. If that is not
possible, please apply some Vaseline onto the seals for greasing. The
plugs are coded and only fit in one direction. Please do not use force!

Notes on installation, removal, storage,
maintenance, and use
Installation, repair, commissioning, and decommissioning may only be
carried out by the manufacturer of the pedelec or an authorized specialist
workshop.
During installation, ensure that the ergonomic principle and functionality
of the pedelec are not changed or impaired.
The protection class of the bikespeed RS is IP64. The bikespeed RS does
not require a separate power source. It is supplied with energy from the
battery of the pedelec in which the tuning is installed. This battery is
charged via the power supply unit provided by the manufacturer of the
pedelec.
No maintenance or service is required on the bikespeed RS. After
decommissioning, no special precautions need to be taken to put the
product back into operation.
If the product is stored in a dismantled state, this must be done in a dry
place between 0 and 40 degrees Celsius and 30 to 70 % relative humidity.
Use in the installed state may only be carried out by specially trained and
adult users without physical and physical limitations.
The use is not limited in time but may only take place as long as the
physical and mental condition of the user allows to operate the pedelec
under full concentration.

Example installation on a Nox XC Trail (2020)
Since we cannot provide detailed installation instructions for every bike
available on the market with this motor and display, we have decided to
use this installation example. This example will give you an overview of
the work to be done and you can transfer it to your bike. If you still have
questions, please feel free to contact us at any time.
To access the connectors for connecting the bikespeed RS, a cover on the
motor must be removed and a cable pulled through the frame. Please
follow the instructions on the following pages.
Required tools: different Allen keys
different Torx
Optional: Underlay blocks for the handlebars
(e. g. 2 squared timbers 10 x 10 cm)
The installation may only be carried out by an expert!
All statements without guarantee!
