Setup and Assembly

The KETELES K800 electric bicycle is designed for minimal assembly. Most major components come pre-assembled. Follow these steps to complete the setup:

1. Unpacking: Carefully remove the bicycle and all components from the packaging. Inspect for any shipping damage.
2. Handlebar Installation: Attach the handlebar to the stem, ensuring it is centered and tightened securely. Adjust the angle for comfortable riding.
3. Pedal Installation: Identify the left (L) and right (R) pedals. The left pedal tightens counter-clockwise, and the right pedal tightens clockwise. Ensure they are fully threaded and tightened.
4. Front Wheel Installation: Secure the front wheel into the fork dropouts. Ensure the disc brake rotor is correctly aligned with the caliper. Tighten the quick-release skewer or axle nuts firmly.
5. Seat Post and Saddle: Insert the seat post into the frame's seat tube. Adjust the saddle height for comfortable pedaling with a slight bend in the knee at the bottom of the pedal stroke. Secure the quick-release clamp.
6. Battery Installation: Insert the removable lithium battery into its designated compartment on the frame. Ensure it clicks securely into place. Charge the battery fully before first use.
7. Pre-Ride Check: Before your first ride, perform a thorough check of all bolts, nuts, and quick releases to ensure they are tight. Check tire pressure, brake function, and gear shifting.

   • Cruise Control Mode: (Refer to specific display instructions if available for activation).
3. Gear Shifting: Use the Shimano 21-speed gear shifter on the handlebars to change gears according to terrain and desired speed. Shift smoothly to avoid chain drops or damage.
4. Braking: Use the hydraulic disc brake levers on the handlebars to slow down or stop. Apply both brakes simultaneously for optimal stopping power and control.
5. Headlight and Horn: Operate the headlight and horn using the dedicated buttons on the handlebars for visibility and safety.

Maintenance

Regular maintenance ensures the longevity and safe operation of your KETELES K800 electric bicycle.

• Battery Care:
  • Charge the battery fully after each ride, especially if it will be stored for an extended period.
  • Avoid completely draining the battery.
  • Store the battery in a cool, dry place, away from direct sunlight and extreme temperatures.
  • Charge time is approximately 8-10 hours.
• Tire Pressure: Regularly check and maintain the recommended tire pressure for optimal performance and safety. The fat tires require specific pressure ranges for different terrains.
• Brake System: Inspect brake pads for wear and replace them as needed. Ensure brake levers are responsive and the hydraulic system is free of leaks.
• Chain and Drivetrain: Keep the chain clean and lubricated. Check for wear on the chain, gears, and derailleur.
• Frame and Components: Periodically check all bolts, nuts, and quick releases for tightness. Clean the frame with a damp cloth and mild detergent. Avoid high-pressure washing directly on electrical components.
• Suspension Fork: Keep the suspension fork clean and check for smooth operation.
