Congratulations on the purchase of your ROSE dream bike!
We are pleased that you have decided to buy a ROSE bike and are sure that you will enjoy riding your new bike every
day.
Your bike is unique – before it has found its way to your home, this bike was individually assembled by hand by a
skilled mechanic and carefully inspected by another specialist to ensure it meets our highest quality standards. We thus
guarantee that your bike offers reliability and state-of-the-art technology. Easy-to-use gears and brakes, an excellent
design and great value for money are just some of the reasons why you will love your bike.
Some components were removed or adjusted for shipping. However, they can be easily re-assembled or re-adjusted in
just a few simple steps (see “3. Bike assembly“ on page 14).
Regular care and maintenance (see “9. Maintenance“ on page 35) will prolong the life of your beloved bicycle. This
manual includes all information on handling, maintenance and care you need to properly care for your bike.
We recommend you to carefully check and service your bike at regular intervals. Your safety and a long life of your bike
should be worth the effort.
This manual describes all details you need for a safe use of your bike, as well as the most important and general facts
about your bike. For more detailed information on single bike components, please see the respective owner’s manual
of the manufacturer. All manuals are included in the purchase documents of your bike or available online.
Please take the time to read this manual carefully. The sections marked with the signal words “DANGER“ and
“WARNING“ are of particularly high importance. The instructions contained in these warnings must be followed.
Moreover, we recommend you to follow the steps described in “7. Before and after your ride“ on page 30 and to
have your bike serviced regularly (see “9. Maintenance“ on page 35) to ensure your safety on every ride.
Have fun with your dream bike! Your ROSE Bikes team

1.7 Replacement of parts
As e-bike components are subjected to heavy loads, you cannot simply replace them. In most cases, you must obtain
approval from ROSE Bikes or the component manufacturer before replacing a component. Also see “9.2 Replacement
of parts“ on page 36.
Please contact ROSE Bikes in case of any questions.
1.8 Warranty and guarantee
For all information on warranty and guarantee see rosebikes.com/termsandconditions.
Tuning the e-bike will invalidate the warranty.
If you have purchased a complete bike from us, you are obliged to return the entire bike to make a warranty claim, and
not just the defective components. Only then we can check whether the legal requirements for a warranty claim are
met.

2. Safety
2.1 General safety
DANGER
Inadequate protective equipment can cause injuries!
Effective safety equipment contributes to your personal safety.
• Always wear a helmet.
• Always wear highly visible and reflective clothing.
DANGER
Improperly installed components can cause serious crashes!
Improperly installed components may loosen during the ride!
• Always follow the installation instructions included in this manual.
• If in doubt, please consult the ROSE service or a qualified bicycle mechanic.
DANGER
Risk of accident due to sudden total failure of pre-damaged components!
A fall or unforeseeable manoeuvres can pre-damage components of your bike. Even though you might not
immediately notice those damages, it is always possible that pre-damaged components deform or break while riding.
• Regularly check your components for damages.
• Components that are subject to high stress must be regularly replaced and checked by a qualified bicycle
mechanic.
2.2 Carrying children on a bike
DANGER
Risk of injury when carrying kids in a bike seat or bike trailer!
Carrying children in a bike seat or bike trailer inappropriately may lead to accidents with a high injury potential.
• Please note the information in chapter “6. Cycling with kids“ on page 29.
• Never carry a child in a bike seat or a bike trailer if not all of the conditions in chapter “6. Cycling with kids“ on
page 29 are complied with.
2.3 Safe use of the brakes
DANGER
Risk of accident due to reduced braking performance caused by brake pads that are not broken in!
Disc brakes can only achieve full braking power when the brake pads are broken in. Choose a place off public roads
to break in the pads.
• Brake 20 to 30 times with the front or rear brake from a speed of 30 km/h down to 5 km/h and repeat the
process for the second brake. You should brake as hard as possible without locking one of the wheels.
• Please also see the brake manufacturer’s instructions for more information (see enclosed manual).

9
DANGER
Risk of accident due to high braking power of the disc brakes!
Modern disc brakes have a very high braking power. Sudden braking may cause losing control of your bicycle.
• Make yourself familiar with the power and operation of your disc brakes off public roads.
2.4 Safe use of the e-bike system
DANGER
Using the on-board computer while riding increases the risk of accidents!
Reading from the computer display or changing settings while riding may distract from the traffic situation. This may
result in accidents caused by delayed or hindered rider responses!
• For all settings other than those concerning the level of assistance, you should stop on the side of the road to
enter respective data.
DANGER
Risk of accident due to misjudgement through other road users!
Other road users mostly misjudge the speed of e-bike riders.
• Always ride carefully and never rely on other road users to react properly.
DANGER
Danger caused by increasing the maximum speed or speed limitation of the e-bike!
Pedelec tuning bears incalculable liability risks as well as the risk of irreversible damage to the system!
• It is not permissible to modify the e-bike drive system.
• It is not permitted to mount any products that might be able to increase the power of the e-bike system.
• Improper use of the drive system endangers your safety and the safety of other road users.
• When causing accidents due to manipulations, you risk high liability costs and criminal prosecution.
• All components are adapted to the original performance data of the e-bike. Higher loads may overload the
system, reduce its life and irreversibly damage the system on the long term.
• Guarantee and warranty claims are lost.
WARNING
Risk of injury due to accidental activation of the e-bike drive system!
• Always remove the battery pack from the e-bike before working on the electric bicycle (e.g. servicing, repair,
assembly, maintenance works), as well as before transport (e.g. by car or plane) and storage.

10
NOTE
Risk of damage to the on-board computer!
Improper handling may cause irreparable damage to the on-board computer or its holder.
• Do not use the on-board computer as a handle.
Lifting the e-bike up by the on-board computer can cause irreparable damage to the on-board computer.
• Do not stand your bicycle upside down on its saddle and handlebar.
This may irreparably damage the on-board computer or holder.
• Remove the on-board computer before clamping the bike into a repair stand to ensure that the on-board
computer does not fall off or get damaged.
2.5 Safety instructions for the use of Bluetooth devices®
NOTE
Special instructions for the use of the Bluetooth® function of the on-board computer
Using the on-board computer with Bluetooth
®
may cause interference affecting other devices and systems, aeroplanes
and medical devices (e.g. pacemakers, hearing aids). Injury to people and animals in the immediate vicinity cannot be
excluded entirely.
• Do not use the on-board computer with Bluetooth®in the vicinity of medical devices, petrol stations, chemical
plants, areas with a potentially explosive atmosphere or on blast sites.
• Do not use the on-board computer with Bluetooth®in aeroplanes.
• Avoid using the on-board computer near your body for extended periods.
