6. Operating Your E-Bike
6.1. Riding Modes
The Varstrom ECity offers three distinct riding modes to suit various terrains and preferences:
- Pedal Assistance Mode: This mode provides electric assistance as you pedal. There are 4 adjustable support levels, allowing you to control the amount of power provided by the motor. This is ideal for extending your range and making climbs easier.
- Teaching Aid Mode: This mode likely offers a low-power assist or walk-assist function, useful for learning or maneuvering the bike at very low speeds.
- Bicycle Mode: In this mode, the electric motor is disengaged, and the bike operates like a traditional bicycle, powered solely by your pedaling.
You can easily switch between these modes using the intelligent LCD Display, adapting to road conditions and your personal needs.
6.2. Intelligent LCD Display
The LCD display provides crucial information about your ride and the e-bike's status:
- Battery Capacity: Indicates the remaining charge of your 43.2V 13Ah battery.
- Assistance Level: Shows the current level of pedal assistance (0-4).
- Speed: Displays your current riding speed.
- Total Distance (ODO): Records the total distance traveled by the e-bike.
- Partial Distance (TRIP): Records the distance of your current ride.
The top speed and riding mode can be easily changed via parameter settings accessible through the display.
6.3. Gear System
The Shimano 7-speed transmission system allows for smooth and efficient gear changes, enabling you to adapt to various terrains and maintain an optimal pace. Use the Shimano SL-TX50 shifter on the handlebars to change gears.
6.4. Lighting System
The e-bike is equipped with front and rear LED lights for enhanced visibility and safety, especially during night riding. The tail lights illuminate when the main light is turned on or when the crank is rotated in the opposite direction.
7. Maintenance
Regular maintenance ensures the longevity and optimal performance of your Varstrom ECity e-bike.
7.1. Battery Care
- The 43.2V 13Ah lithium battery supports approximately 3000 charge/discharge cycles.
- It is designed to retain over 80% of its capacity for two years under normal use.
- Always use the original charger provided with your e-bike.
- Avoid completely draining the battery. Charge it regularly, especially if storing the bike for an extended period.
- Store the battery in a cool, dry place, away from direct sunlight and extreme temperatures.
7.2. General Bike Care
- Cleaning: Clean your e-bike regularly with a damp cloth. Avoid using high-pressure washers directly on electrical components.
- Tire Pressure: Check tire pressure before each ride. The Kenda 700x40 tires require appropriate inflation for safety and performance.

- Chain: Keep the chain clean and lubricated for smooth gear changes and to prevent wear.

8. Troubleshooting
This section addresses common issues you might encounter with your e-bike. For more complex problems, please contact customer service.
| Problem | Possible Cause | Solution |
|---|---|---|
| E-bike does not power on. | Battery is not charged or not properly connected. | Ensure the battery is fully charged and securely seated in its compartment. Check all electrical connections. |
| Motor assistance is weak or non-existent. | Low battery charge, incorrect assistance level selected, or sensor issue. | Charge the battery. Check the LCD display to ensure a pedal assistance level (1-4) is selected. Ensure pedal sensor is clean and unobstructed. |
| Gears are not shifting smoothly. | Dirty or unlubricated chain, misaligned derailleur, or worn cables. | Clean and lubricate the chain. If the issue persists, a professional adjustment of the derailleur may be needed. |
