How do I adjust the pedal assist level?

Use the increase and decrease arrow buttons on the display. Press the increase button to raise the assist level and the decrease button to lower it. The level is shown on the display from 0 to 5 (or similar). Note that the levels do not cycle; you must decrease back to 0.

How do I enter walk mode?

Press and hold the decrease arrow button to activate walk mode. The walk mode indicator will appear on the display. Release the button to stop walk mode.

What is the maximum speed of the Pathfinder 500?

With pedal assist, the bike can reach up to 25 mph. With throttle only, up to 20 mph. The bike can be configured as Class 1, 2, or 3 e-bike.

How do I remove and install the battery?

Turn the lock clockwise to unlock, then pull the battery from the bottom to remove. To install, insert the top of the battery into the frame first, then push the bottom in until it clicks. Ensure the key is removed and the battery is locked.

How do I reset the trip mileage?

Press and hold both the increase and decrease arrow buttons simultaneously for 2 seconds to clear the single trip mileage.

What is the correct tire pressure?

The manual does not specify a specific tire pressure. Check the tire sidewall for recommended pressure range, typically between 20-40 psi for fat tires. Inspect tire condition before each ride.

How do I adjust the seat height?

Loosen the quick-release lever on the seat tube. Adjust the seat post to the desired height, ensuring the minimum insertion line is inside the frame. Tighten the lever with noticeable effort. The rider's leg should be nearly fully extended when the pedal is at the bottom.

Can I use a different charger?

Only use the original charger provided by Magnum or a certified replacement. Using an incompatible charger may damage the battery or cause safety hazards.

How do I clean the e-bike?

Use a soft cloth with a neutral solution to wipe the shells and parts. Avoid excessive water, high-pressure hoses, or soap on metal components. Dry with a clean cloth. Do not wash plastic components with excessive water.

2. Installation and Adjustment

2.1 Handlebar and Stem Assembly

1. Loosen the screws on the faceplate of the stem. Remove the faceplate and set aside.

1. Center the handlebar and put the faceplate back in place. Tighten the 4 faceplate screws in a star pattern.

Handlebar & Stem Adjustment

To adjust the angle of your stem loosen the stem bolt (1).

2. Installation and Adjustment

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.

WARNING

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

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

Optimal

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 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.

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.

Recommended Torque Values
Handlebar 8-10 Newton Meters
Stem 8-10 Newton Meters
Saddle 18-20 Newton Meters
Front Wheel 16-25 Newton Meters
Rear Wheel 35-40 Newton Meters
Bottom Bracket Parts 35-55 Newton Meters
Pedals 35 Newton Meters
Rotor Bolts 6 Newton Meters
Disk Caliper Mount 10 Newton Meters
Crank Bolts 40 Newton Meters
Rear Derailleur Cable Pinch 6 Newton Meters
Front Derailleur Clamp 7 Newton Meters
Saddle Post Clamp 7 Newton Meters

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.

⚠ 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.
