INSTALLATION AND ADJUSTMENT

2.1 Handlebar and Stem Assembly

1. Open the top cover, align the stem with the head tube and slide it on. Tighten the screw at the top of the stem.

2. Align the handlebar to be perpendicular to the wheel, then insert and tighten the two side-facing screws as shown below.

3. Move the handlebar up or down to adjust to the desired angle, then tighten the rear-facing screw at the top of the stem to lock the handlebar in place.

4. Close the cover to complete installation and adjustment.

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.

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.

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 to ride position.
– Tighten the bolt (4) to secure the saddle.

 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.

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 indicates 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.
