3. Setup and Assembly

Your Leader Fox CURTIS X tricycle may require some assembly upon arrival. It is recommended that assembly be performed by a qualified bicycle mechanic.

3.1 Unpacking

Carefully remove all components from the packaging. Retain packaging materials for potential future transport or warranty claims. Check for any visible damage during shipping.

3.2 Handlebar Installation

  1. Insert the handlebar stem into the fork steerer tube.
  2. Align the handlebars straight with the front wheel.
  3. Tighten the stem bolts securely to the manufacturer's specified torque.

3.3 Seat Post and Saddle Adjustment

  1. Insert the seat post into the frame's seat tube.
  2. Adjust the saddle height so that your leg has a slight bend at the knee when the pedal is at its lowest point.
  3. Ensure the seat post is inserted beyond the minimum insertion line.
  4. Tighten the quick-release or bolt securely.

3.4 Pedal Installation

Note that pedals are left (L) and right (R) specific. The right pedal tightens clockwise, and the left pedal tightens counter-clockwise.

  1. Apply a small amount of grease to the pedal threads.
  2. Carefully thread the pedals into the crank arms by hand to avoid cross-threading.
  3. Tighten firmly with a pedal wrench.

3.5 Battery Installation and Initial Charge

Locate the battery compartment. Insert the battery and ensure it clicks securely into place. Connect the charger to the battery and then to a power outlet. Charge the battery fully before first use. Refer to the battery indicator on the LCD display for charge status.

4. Operating Instructions

4.1 Powering On/Off

To power on the electric system, press and hold the power button on the LCD display for a few seconds. To power off, repeat the process.

4.2 LCD Display Functions

The LCD display provides information such as speed, mileage, battery level, and assistance mode. Use the '+' and '-' buttons to navigate through different display modes and adjust assistance levels.

4.3 Pedal Assist Modes

The BAFANG motor offers 5 levels of pedal assistance. Select the desired level using the display controls. Higher levels provide more motor assistance, while lower levels require more rider effort and conserve battery life.

4.4 Walk Assist Function

The tricycle includes a "WALK" function to assist when pushing the tricycle on foot. Activate this function via the LCD display controls. The motor will provide low-speed assistance.

4.5 Gearing (Shimano Nexus 8-speed)

The Shimano Nexus 8-speed internal gear hub allows for smooth gear changes even when stationary. Use the shifter on the handlebar to select the appropriate gear for your terrain and speed.

4.6 Braking

The tricycle is equipped with front and rear brakes. Apply both brakes simultaneously and smoothly for effective stopping. Avoid sudden, hard braking, especially at high speeds or on loose surfaces.

4.7 Cargo Capacity

The tricycle features a generous rear cargo space. Ensure that any cargo is evenly distributed and securely fastened to prevent shifting during operation. Do not exceed the maximum load capacity specified in the specifications section.

5. Maintenance

Regular maintenance is crucial for the longevity and safe operation of your electric tricycle.

5.1 Cleaning

Clean the tricycle regularly with a damp cloth and mild soap. Avoid using high-pressure washers directly on electrical components, bearings, or seals.

5.2 Tire Pressure

Check tire pressure before each ride. Maintain the recommended pressure (usually indicated on the tire sidewall) for optimal performance, range, and safety.

5.3 Brakes

Regularly inspect brake pads for wear and replace them when necessary. Ensure brake levers are firm and responsive. Adjust brake cables as needed to maintain proper tension.

5.4 Chain and Drivetrain

Keep the chain clean and lubricated. Inspect for wear and replace if stretched. The Shimano Nexus internal gear hub requires minimal maintenance but should be checked periodically by a professional.

5.5 Battery Care

  • Charge the battery regularly, even if not in use, to maintain its health.
  • Store the battery in a cool, dry place, away from direct sunlight and extreme temperatures.
  • Do not fully discharge the battery frequently.
  • Use only the original charger provided with the tricycle.
