2. Quick Start Guide

2.1 Assembly Instructions

General Assembly Advice:

• Ensure the system is powered off before starting assembly.
• Two people may be needed for disassembly and installation.
• Check that all parts are present and undamaged before assembly.
• Maximum Load: 200KG / 440lbs.

2.1.1 Assembly - Notice

Warning: Ensure the system is powered off before installation. Two people are recommended for assembly and installation.

2.1.2 Unpacking

Carefully remove all components from the packaging. The main frame is typically the largest item. Ensure all small parts and tools are accounted for.

2.1.3 Control Area Installation

Step 1: Attach the handlebar riser to the frame's steering tube using the provided screws (e.g., M5). Ensure it is tightened securely.

Step 2: Install the handlebar onto the riser. Align the handlebar and tighten the stem bolts (e.g., M5) evenly.

Step 3: Install the brake levers and throttle onto the handlebar. Position them for comfortable reach and tighten the clamps.

Step 4: Install the bell and any other accessories onto the handlebar.

2.1.4 Front Fender and Headlight Installation

Step 1: Align the front fender with the mounting points on the front fork. Secure it using the provided screws (e.g., M5).

Step 2: Mount the headlight to the designated bracket on the front fork or frame. Connect its wiring harness to the bike's electrical system.

2.1.5 Wheel Installation

Step 1: For the front wheel, align the axle with the dropouts on the front fork. Ensure the brake rotor aligns with the brake caliper. Secure the wheel using the quick-release lever or axle nuts.

Step 2: For the rear wheel (often containing the motor), carefully align the axle with the rear dropouts. Ensure the chain engages with the cassette/freewheel. Connect the motor's wiring harness to the controller.

2.1.6 Saddle Installation and Adjustment

Step 1: Insert the seat post into the seat tube of the frame. Ensure the minimum insertion line is not visible.

Step 2: Attach the saddle to the seat post clamp. Adjust the saddle angle and position.

Step 3: Tighten the seat post quick-release lever or clamp bolt to secure the saddle height. Adjust the saddle height so that when the pedal is at its lowest point, your leg is slightly bent.

2.1.7 Rear Light Installation

Mount the rear light to the seat post or rear fender using the provided bracket and screws. Connect its wiring harness.

2.1.8 Pedal Installation

Step 1: Identify the left (L) and right (R) pedals. The right pedal usually has a standard thread (clockwise to tighten), and the left pedal has a reverse thread (counter-clockwise to tighten).

Step 2: Thread the pedals into the crank arms by hand to avoid cross-threading. Tighten them securely with a pedal wrench.

2.1.9 Installation Complete

After all components are installed, double-check all bolts and connections for tightness. Ensure wheels spin freely and brakes function correctly.
