Working Modes
The CycFree-MAX offers three distinct riding modes:
- 1. Pedal Assist Mode (PAS): The motor provides assistance as you pedal. There are multiple assist levels (1-5) to choose from, influencing the amount of motor support. This mode offers a range of 85-120 KM.
- 2. Pure Electric Mode: Twist the throttle to engage the motor without pedaling. This mode provides a range of 67-85 KM.
- 3. Pedal Mode: Ride the bicycle like a traditional non-electric bike, using only your pedaling power. This mode offers unlimited range.
Gear Shifting
The bike is equipped with a 7-speed Shimano gear system. Use the shifter on the handlebar to change gears, adapting to different terrains and riding conditions. Shift gears smoothly to avoid strain on the drivetrain.
Lighting and USB Charging
The bike features integrated front and rear taillights for enhanced visibility, especially during nighttime riding. A USB charging port is available on the handlebar, allowing you to charge your mobile devices while riding.
The USB charging port allows convenient charging of mobile devices directly from the bike's battery.
5. Battery Information
The CycFree-MAX is powered by a detachable 48V 20Ah lithium-ion battery, designed for extended range and reliability.
Charging the Battery
- The battery can be charged while installed on the bike or removed for convenience.
- Use only the provided 54.6V 3A fast charger.
- A full charge typically takes 5-6 hours.
- The intelligent Battery Management System (BMS) protects against overcharging and over-discharging, extending battery life.
The 48V 20Ah removable battery can be charged on or off the bike using the included fast charger.
Battery Care
- Store the battery in a cool, dry place when not in use.
- Avoid fully depleting the battery regularly.
- Charge the battery at least once every two months if not used for extended periods.

6. Maintenance
Regular maintenance ensures the longevity and safe operation of your electric bike.
- Cleaning: Clean the bike regularly with a damp cloth. Avoid high-pressure washing directly on electrical components.
- Tires: Check tire pressure before each ride. The 20" x 4.0 fat tires provide excellent traction but require proper inflation for optimal performance and safety.
- Brakes: Inspect disc brakes for wear and proper function. Ensure brake levers are responsive and provide adequate stopping power. Adjust or replace brake pads as needed.
- Suspension: The front hydraulic suspension system should be checked periodically for smooth operation. Keep suspension components clean.
- Chain: Keep the chain clean and lubricated to ensure smooth gear changes and prevent wear.
- Fasteners: Periodically check all bolts and fasteners for tightness.
The front hydraulic suspension system provides a comfortable ride by absorbing shocks from uneven terrain.
7. Troubleshooting
This section addresses common issues you might encounter with your CycFree-MAX electric bike.
| Problem | Possible Cause | Solution |
|---|---|---|
| Bike does not power on | Battery not charged or not properly installed; power button not pressed correctly. | Ensure battery is fully charged and securely seated. Press and hold the power button firmly. |
| Motor not assisting | Pedal assist level (PAS) set to 0; throttle not engaged; brake levers engaged. | Increase PAS level. Ensure throttle is twisted fully. Release brake levers. |
| Short battery range | Low tire pressure; riding uphill frequently; heavy load; cold weather. | Inflate tires to recommended pressure. Use lower assist levels or pedal more. Reduce load. Battery performance decreases in cold weather. |
| Brakes feel weak | Worn brake pads; loose brake cable; air in hydraulic system (if applicable). | Inspect and replace brake pads. Adjust brake cable tension. Consult a professional for hydraulic brake issues. |
