GENERAL

1. General Introduction

1.1 Welcome

Thank you for purchasing a Magnum electric bike and welcome to the Magnum Bikes family of e-bike enthusiasts. We

encourage you to join our Facebook group “Magnum Bikes Community” which you can find at the following link:

https://www.facebook.com/groups/389290978573773

Our Facebook group is a place for Magnum riders to ask questions, have discussions, share recommendations and

experiences and connect with other Magnum Bike enthusiasts.

1.2 Use of the Manual

We encourage you to read this manual thoroughly before you take your new E-bike for a ride. It is important not to overlook
the safety instructions and explanations of both traditional and non-traditional bike parts, as this will offer you a general
understanding of your new E-bike. This manual is designed to help you get the most out of your E-bike, and so we have
attempted to answer as many of your potential questions as possible. 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 reference. For
technical support, including information about service, maintenance and repairs, please consult your dealer. You can visit
our website (www.magnumbikes.com) for more information about our products and technology, or to find a dealer close
to you.

03

INSTALLATION AND ADJUSTMENT

2.2 Assembly of the Pedals

- Identify your pedals: check the letters on the pedals, "L" or "R".

- The "R" marked pedal is for the right (when facing the forward direction). For attachment to the crank, tighten clockwise.

- The "L" marked pedal is for the left. For attachment, tighten counterclockwise when facing directly.

WARNING:

First screw on the pedals by hand, then tighten with the wrench provided.

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 flat on the pedal in the bottom position
of the crank cycle. The toes must still be able to touch the ground comfortably.

Too low Too high

Optimal

INSTALLATION AND ADJUSTMENT

MIN INSERT

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.

2.5 Saddle Adjustment

The saddle can also be tilted and adjusted in the forward/back

direction.

- Loosen the bolt at the bottom (4).

- Adjust the saddle tilt by pressing down on the front or rear of the
saddle

- Move the saddle forward or backward to adjust for arm/torso length
and desired riding position.

- Tighten the bolt (4) to secure the saddle.

RECOMMENDATIONS AND MAINTENANCE

5. Recommendations and Maintenance

5.1 General Requirements

E-bikes use metal shells to cover the electric components, so 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.

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.

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 at before you make modifications or add parts, in order to confirm their safety and
compatibility with your bike.
