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 website (www.

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.
*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.

2.Installation and Adjustment
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 at on the pedal in the
bottom position of the crank cycle. The toes must still be able to touch the ground comfortably.

2.Installation and Adjustment
2.4 Saddle Height
The quick-release lever must require noticeable effort to put into fully closed position to prevent any unde-
sired 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.
MININSERT
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.

Recommendations & Maintenance
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.

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.

Recommendations & Maintenance

5.3 Denition of Tampering and Recommendations
Modications to any part of your bike, such as the fork or frame, may make that part or the entire bike un-
safe. A poorly installed or modied component can increase the stress on all other parts, greatly increasing
their chance of failure. Modications 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 modica-
tions or add parts, in order to conrm their safety and compatibility with your bike.
