4. Operating Instructions

Understanding how to operate your BURCHDA HC26 will enhance your riding experience.

Powering On/Off and Display

The digital display provides crucial information during your ride. It shows battery level, headlight status, current speed, selected riding mode, trip distance, and gear display. Refer to the display manual for detailed operation.

• Power On: Press and hold the power button on the display unit.
• Power Off: Press and hold the power button again.
• Display Functions: Navigate through different display screens using the control buttons to view speed, battery level, odometer, trip distance, and assistance level.

Riding Modes

This diagram explains the three available riding modes and their approximate electricity consumption.

• Human Riding Mode (Pedal Only): 0% electricity consumption. Ride the bike like a traditional bicycle using only pedal power.
• Electric Mode (Throttle Only): Approximately 50% electricity consumption. Engage the throttle for pure electric propulsion without pedaling. This mode offers an unexpectedly fast riding experience.
• Intelligent Power-Assisted Mode (Pedal Assist): Approximately 100% electricity consumption (variable based on assist level). The motor provides assistance as you pedal, making riding easier, especially on inclines. Adjust the assistance level via the display.

Gear Shifting

The 7-speed transmission system allows you to easily switch gears while riding, helping you conquer various terrains and achieve exceptional acceleration. Use the gear shifter on the handlebar to change gears smoothly.

Braking System

The dual hydraulic oil brakes provide powerful and reliable stopping power. When the brake lever is pressed, the motor power is cut off, ensuring quick and stable braking. Regularly check brake pad wear and brake fluid levels.

5. Maintenance and Care

Regular maintenance ensures the longevity and optimal performance of your BURCHDA HC26 electric bike.

• Battery Care:
  • Charge the battery fully before first use.
  • 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 completely discharge the battery.
  • The estimated battery life depends on rider weight, speed, temperature, wind, tire pressure, terrain, slopes, and other conditions. Mileage may vary.
• Tire Pressure: Check tire pressure before each ride. Maintain the recommended PSI (pounds per square inch) indicated on the tire sidewall for optimal performance and safety.
• Brakes: Inspect brake pads for wear and replace them when necessary. Ensure brake levers are firm and responsive. Check hydraulic fluid levels periodically if applicable.
• Chain and Drivetrain: Keep the chain clean and lubricated. Regularly inspect the chain, gears, and derailleur for wear or damage.
• Cleaning: Clean the bike regularly with a damp cloth. Avoid using high-pressure washers directly on electrical components. Dry thoroughly after cleaning.
• Fasteners: Periodically check all bolts, nuts, and quick releases for tightness. Loose components can affect safety and performance.
• Storage: Store the bike in a dry, sheltered area. If storing for extended periods, ensure the battery is partially charged (around 50-70%) and recharged every 1-2 months.
