Installation and Adjustment
Handlebar and Stem Assembly
- Remove the faceplate from the stem with a 4mm allen key.

- Remove the display for easy installation. Lift the handlebars (attached to the cables and display) and center them with the head tube.

- Attach the faceplate using a 4mm allen key. Re-install the display

Front Wheel Installation
Place the front wheel between the fork. Insert axle into non-drivetrain side. Use a 6mm allen key to tighetn the axle.
Pedal Installation
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
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.

Saddle Height & Adjustment
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.
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.
Fork Adjustment
Rotate the lever (1) to lock the suspension
Brakes
The front and rear brakes operate independently of each other. When stopping or slowing down, use both brakes at the same time.
The left brake lever (1) controls the front brake.
The right brake lever (2) controls the rear brake.
Safety Checks & Adjustments
Crank Arm
The crank arm (1) in some circumstances can loosen. Regularly check the crank arm is securely tighened before riding. No play should be felt when pulling or pushing the crank arm to the side.
If the bottom bracket (2) is loose or does not rotate easily contact Magnum support. The screws (3) tighten on both sides of the bottom bracket
Pedals
Regularly check that the pedals (4) are firmly screwed into the pedal crank arms. Use 15mm open end wrench to tighten
Headset Bearings
Riding with a loose steering bearing (1), breakage of the fork shaft (2) can occur which can result in serious injury to the rider. Use the brake lever (3) and move the bicycle back and forth.
Any play or wiggle in the steering bearing (1) must be adjusted by tightening the stem up. Loosen stem screws (4), tighten stem cap (5) 1/4 turn at a time until there is no more play. Tighten stem screws (4).
Spokes
Spokes (1) can loosen over time. It is important to maintain proper spoke tension to prevent breaking spokes. Broken spokes should be replaced immediately and the wheel must be trued.
Replacing, re-tensioning, and truing of the wheel or spokes should be done by a Magnum dealer or bike specialist.

Pedal Assist Level
Short press the arrow buttons to adjust the pedal assist level up or down. There are 5 PAS levels: ECO, TOUR, SPORT, TURBO, BOOST, and BOOST+. BOOST+ is indicated by a blinking BOOST icon. When PAS level is empty it means pedal assist is off.
PAS levels do not switch in cycles. Meaning, after reaching the BOOST level pressing the up arrow will NOT cycle the levels back to the beginning. The user must use the down arrow button to switch back down to PAS off.

Trip, Odometer, & Range
Short press the M button to switch from TRIP, ODO, & RANGE on the display. The cycle order is TRIP/AVG, ODO/MAX, then RANGE/AVG. After 5 seconds with no operation preformed on the M button and the bike speed greater than 0 the display screen will switch back to the main interface. The symbols below will indicate which value is being shown.
Light Control
Long press the adjust up button to turn the headlight on and off. While the headlight is on the display’s back light is dimmed.
Speed Indication
The standard readout is real time speed, and can be switched to show average speed (AVG), and maximum speed (MAX). How to change speed readout…
Battery Power
Battery power is shown by a battery bar indicator and percentage. The battery bar divides the power level into 5 bars. After battery capacity is lower than 5% the display enters low voltage mode. In this mode the battery level shows 0 bars. The battery outline will start blinking after reaching 1Hz, and with no power output from the motor, pedal assist will be disabled. The PAS level is displayed as OFF or 0. To get out of low voltage mode the battery will need to be charged.
Walk Mode
When speed is below 3mph long press and continue to hold the adjust down (down arrow) button to enter walk mode. Upon entering walk mode the display will show a walk mode symbol and the real-time speed while the PAS level displays as off (see image below). Release the adjust down button to exit walk mode. The motor is turned off and the display returns to the main interface.

Recommendations and Maintenance
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.

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.
