3. Pedal Assist System (PAS):
   • The bike operates with electric pedal assistance. The motor provides power only when you are pedaling.
   • Use the controls on the handlebar to select your desired assist level (1-4). Higher levels provide more motor assistance.
4. Shifting Gears:
   • Your bike is equipped with a Shimano 7-speed transmission (Sh1mano RD-TY300 Rear Derailleur, Sh1mano SL-TX50 Shifter, Sh1mano MF-TZ500-7 Sprocket).
   • Use the shifter on the handlebar to change gears. Shift to lower gears for climbing hills and higher gears for flat terrain or descents.
   • Always ease off pedaling pressure slightly when shifting for smoother transitions.
5. Braking:
   • The bike features Hydraulic Disc Brakes (front 180mm / rear 160mm).
   • Apply both brake levers simultaneously for effective and controlled stopping.
   • Hydraulic brakes offer strong stopping power and require less effort.

5. Maintenance

Regular maintenance ensures the longevity and safe operation of your Varstrom E-City Bike.

• Battery Care:
  • Charge the battery regularly, even if not in use, to maintain its health.
  • Avoid completely draining the battery.
  • Store the battery in a cool, dry place, away from direct sunlight and extreme temperatures.
  • Use only the original charger provided.
• Tires: Check tire pressure before each ride. Proper inflation improves efficiency and reduces the risk of punctures.
• Brakes: Regularly inspect brake pads for wear and replace them when necessary. Ensure brake levers feel firm and responsive.
• Chain and Drivetrain: Keep the chain clean and lubricated. Periodically check the gears for smooth shifting and adjust if needed.
• Bolts and Fasteners: Periodically check all bolts, nuts, and quick releases for tightness. Loose components can lead to accidents.
• Cleaning: Clean your e-bike with a damp cloth and mild soap. Avoid using high-pressure washers directly on electrical components.
• Professional Service: For complex issues or annual tune-ups, it is recommended to take your e-bike to a certified bicycle mechanic or a Varstrom service center.
