1.General Introduction
1.1 Welcome

group “Magnum Bikes Community”. Our Facebook group is a place for Magnum
riders to ask questions, have discussions, share recommendations and

1.2 Use of Manual
We encourage you to read this manual thoroughly before you take your new
E-bike for a ride. It is essential not to overlook the safety instructions and
explanations of both traditional and non-traditional bike parts. So please
take a moment to read through the various sections before you get in the
saddle.
1.3 Service and Technical Support
This manual is intended as a general overview of your new E-bike, and is
therefore not an extensive refer-ence. Please consult your local Magnum dealer
or Magnum customer support team for technical support, including information
about service, maintenance, and repairs. In addition, you can visit our

*Disclaimer
Because it is impossible to anticipate every situation or condition which can
occur while riding, this manual makes no representations about the safe use of
bicycles under all conditions. There are risks associated with the use of any
bicycle which cannot be predicted or avoided, and which are the sole
responsibility of the rider. You should keep this manual along with any other
documents that were included with your bicycle. All content in this manual is
subject to change without notice. Magnum Bikes makes every effort to ensure
accuracy of its documentation and assumes no responsibility of liability if
any errors or inaccuracies appear within. Assembly and initial adjustments of
your Magnum e-bike requires special tools and skills. It is recommended that
this be done by a trained bicycle mechanic if possible.
1.4 E-Bike
1.5 Technical Data
2. Installation and Adjustment
Handlebar & Stem Adjustment
To adjust the angle of your stem loosen the stem bolt (1).
2.2 Assembly of the Pedals
Identify your pedals: check the letters on the pedals, “L” or “R”.
Right and left are the same as when you are riding the bike. The “R” and “L”
marked pedals are for the right and lefts sides of the bike as if you were
riding it.
The “R” marked pedal is for the right, thread it into the crank clockwise and tighten.
The “L” marked pedal is for the left., thread it into the crank counterclockwise and tighten.
Warnings: First screw on the pedals by hand, then tighten with the wrench provided.
2.3 Seat Position
To enable comfortable, fatigue-free and safe riding, the saddle and handlebar height should be adjusted to the body size of the rider.
The saddle height is correct if the leg is near full extension while the foot is resting flat on the pedal in the bottom position of the crank cycle. The toes must still be able to touch the ground comfortably.
2.4 Saddle Height
The quick-release lever must require noticeable effort to put into fully
closed position to prevent any undesired movement while riding.
WARNING
An improperly closed quick release lever can open again or have limited
ability to keep the saddle in place. This may cause the saddle to suddenly
drop into the seat tube, potentially leading to serious falls and injury.
There is a minimum insertion line marked on the seat post (failure to observe the minimum insertion line can result in serious injury); please ensure the seat post is always inserted into the seat tube beyond this line (the line must be inside the seat tube).
Loosen the quick release lever at the top of the seat tube, determine the appropriate saddle height and tighten the clamp.
The clamping force can be adjusted by adjusting the bolt on the quick release
lever.
The quick release lever must be closed with considerable counter pressure.
3. Battery and Charger
3.4 Charging
Charging at temperatures below 32°F (0°C) or above 140°F (60°C) can cause the

5. Recommendations and Maintenance
5.1 General Requirements
E-bikes use metal shells to cover the electric components, we strongly advise
against the use of excessive water to wash the shells and parts around them.
Use a soft cloth with a neutral solution to wipe the dirt off the shells.
Afterward, wipe everything dry with a clean soft cloth.
Do not use high-pressure water or air hoses for cleaning; this can force water into electrical components, which may cause malfunctioning.
Do not wash plastic components with excessive water. When the internal electrical parts are affected by water the insulator may corrode, leading to power-drain or other problems.
Do not use soap solutions to wash the metal components. Non-neutral solutions may cause discoloration, distortion, scratching, etc.
Avoid leaving the bike outdoors
When not riding, keep the bike in a location where it will be protected from
snow, rain, sun, etc. Snow and rain can cause the bike to corrode. Ultraviolet
rays from the sun can cause unnecessary fading of paint or crack any rubber or
plastic on the bike.
5.2 Maintenance Schedule
To keep your E-bike in optimal condition and your riding experience at its
most enjoyable, we strongly recommend following the suggested maintenance
schedule. You should study it and allow it to become second nature to your
riding.
Warning
As with all mechanical components, electrically power assisted cycles (EPAC) are subjected to wear and high stresses. Different materials and components may react to wear or stress fatigue in different ways. If the design life of a component has been exceeded, it may suddenly fail, possibly causing injuries to the rider. Any form of crack, scratches or change of coloring in highly stressed areas indicate that the life of the component has been reached and it should be replaced.
5.3 Definition of Tampering and Recommendations
Warning
Modifications to any part of your bike, such as the fork or frame, may make that part or the entire bike unsafe. A poorly installed or modified component can increase the stress on all other parts, greatly increasing their chance of failure. Modifications can also adversely affect the handling of your bike, resulting in loss of control, falls and serious injury. Please do not add, remove, or modify parts of your bike in any way before consulting with a trained bike technician. We recommend you consult with us before you make modifications or add parts, in order to confirm their safety and compatibility with your bike.
