1. Setup and Assembly

Your Soumye Electric Tricycle arrives approximately 90% pre-assembled. The following steps detail the final assembly process. All necessary tools are included.

1.1 Unboxing and Initial Inspection

Carefully open the packaging and remove all components. Verify that all parts listed in the packing list are present and undamaged. It is recommended to lay out all parts on a clean, flat surface.

1.2 Front Wheel and Handlebar Installation

The front wheel and handlebar require careful installation. Ensure the front fork is correctly oriented before installing the wheel. The motor cable on the front wheel should point towards the ground. Secure all screws firmly.

Note on Front Wheel Installation: Some users may find the front fork difficult to align with the wheel. Ensure the fork is rotated correctly and the motor cable is positioned downwards. Loosen the pre-installed screws on the wheel axle, align the wheel with the fork, and then fully tighten the screws on both sides to secure the wheel. The handlebar stem should be adjusted to the desired angle and fully tightened once positioned, ensuring it is perpendicular (T-shape) to the front tire for proper steering.

1.3 Brake Installation and Adjustment

Install the front brake caliper onto the disc rotor. Secure the caliper by tightening the two screws. After installation, spin the wheel to ensure the brake is not rubbing against the disc rotor. Adjust as necessary.

1.4 Fender and Light Installation

Install the front fender and headlight. Connect the front light cable. Secure the fender strings with screws on both sides of the fork. For the rear fender, install both sides to the frame.

1.5 Basket Installation

Remove the pre-installed screws from the front basket mounting area. Secure the front basket using these screws. For the rear basket, remove the screws from the frame, install the basket, and secure it with the four screws. Place the provided cover inside the basket.

1.6 Pedal Installation

Install the right side pedal by turning it in a clockwise direction. Install the left side pedal by turning it in a counter-clockwise direction. Ensure both pedals are fully tightened.

1.7 Saddle and Seat Post Installation

Insert the seat post with the saddle into the frame. Adjust the height for comfortable riding and secure it with the quick-release lever. The saddle can be rotated 90 degrees for easy battery access.

1.8 Battery Installation and Lock

Ensure the battery is fully charged before first use. Insert the battery into its compartment. Turn the key to the unlock stage to disengage the lock, then push the battery in. Turn the key to the off stage to engage the battery lock, securing it in place.
