Maintenance

Regular maintenance ensures the longevity and safe operation of your Vakole SG20 e-bike.

Battery Care:

• Charging: Always use the original charger. Do not overcharge or completely drain the battery. Charge in a well-ventilated area, away from flammable materials.
• Storage: If storing the bike for an extended period, charge the battery to about 50-70% and store it in a cool, dry place. Recharge every 1-2 months to maintain battery health.
• Temperature: Avoid exposing the battery to extreme temperatures (hot or cold).

General Bike Maintenance:

• Cleaning: Clean the bike regularly with a damp cloth. Avoid using high-pressure water jets directly on electrical components. The bike has an IP65 waterproof rating, meaning it is protected against dust and low-pressure water jets, but not immersion.
• Tires: Check tire pressure before each ride. The 20x4.0 inch fat tires require specific pressure for optimal performance and comfort. Inspect for wear and tear.
• Brakes: Regularly inspect the KTET Hydraulic oil disc brakes for wear on pads and proper fluid levels. Ensure brake levers are responsive.
• Chain: Keep the chain clean and lubricated to ensure smooth gear changes and prevent premature wear.
• Fasteners: Periodically check all bolts, nuts, and quick releases to ensure they are securely tightened.
• Suspension: Inspect the front fork suspension for proper function and cleanliness.

Troubleshooting

Here are some common issues and their potential solutions:

• Bike not powering on:
  • Check if the battery is properly inserted and locked.
  • Ensure the battery is charged.
  • Verify all electrical connections are secure.
• Motor not assisting:
  • Check the battery level on the LCD display.
  • Ensure you are in pedal-assist or electric-only mode.
  • Check for any error codes on the LCD display.
• Brakes feel weak:
  • Inspect brake pads for wear and replace if necessary.
  • Check for air in the hydraulic system (may require professional service).
  • Ensure brake calipers are properly aligned.
