Your VARSTROM Cola Bear 2.0 may arrive partially assembled. Follow these general steps for final assembly:

1. Unpacking: Carefully remove all components from the packaging. Retain packaging for potential future transport or warranty claims.
2. Handlebar Installation: Attach the handlebar to the stem, ensuring it is centered and tightened securely.
3. Front Wheel Installation: If the front wheel is separate, install it into the front fork, ensuring the quick-release or axle nuts are properly secured.
4. Pedal Installation: Identify left (L) and right (R) pedals. Apply a small amount of grease to the threads and screw them into the crank arms. Note that the left pedal is reverse-threaded. Tighten firmly.
5. Seat Post and Saddle: Insert the seat post into the frame and adjust the saddle height for a comfortable riding position. Secure with the quick-release lever or bolt.
6. Initial Battery Charge: Before your first ride, fully charge the battery. Connect the charger to the battery port and then to a power outlet. The charging indicator on the charger will show charging status (typically red for charging, green for full). Charging time is approximately 6-8 hours.
7. Pre-Ride Checks: Before every ride, ensure:
   • Tire pressure is within the recommended range (check tire sidewall).
   • Brakes are functioning correctly and levers are easily accessible.
   • All bolts and quick-releases are tight.
   • The battery is securely seated and locked (if applicable).
   • The display powers on and shows battery level.

6. Operating Instructions

Familiarize yourself with the controls and functions of your e-bike before riding.

6.1. P860ML Color LCD Display

The P860ML display is your control center. It shows vital information and allows you to adjust settings.

• Power On/Off: Press and hold the power button on the display to turn the system on or off.
• Information Display: The display shows:
  • Time
  • Battery level
  • Brake status
  • PAS (Pedal Assist System) Level
  • Current Speed
  • Motor Power output
  • Total Mileage (ODO) / Trip Mileage
  • Error indicators (if any)
• PAS Level Adjustment: Use the '+' and '-' buttons to cycle through the Pedal Assist Levels. Higher levels provide more motor assistance.
• Headlight: The display may have a button or setting to control the integrated front light.

6.2. Riding Modes

• Pedal Assist (PAS): The motor provides assistance based on your pedaling effort and the selected PAS level. This is the most common and efficient riding mode.
• Throttle (if equipped): Some models may include a thumb or twist throttle for on-demand power without pedaling. Use with caution and according to local regulations.

6.3. Gear Shifting

Your e-bike is equipped with a SHIMANO 11-speed gear system. Use the shifters on the handlebar to change gears. Shift to lower gears for climbing hills and higher gears for flat terrain or descents. Shift smoothly and avoid shifting under heavy load.

6.4. Braking

The VARSTROM Cola Bear 2.0 features front and rear TEKTRO disc brakes. Apply both brakes simultaneously for effective and controlled stopping. Practice braking in a safe area to understand their responsiveness.

7. Maintenance

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

• Battery Care:
  • Charge the battery after every ride, or at least once a month if not in use.
  • Store the battery in a cool, dry place, ideally between 10°C and 20°C (50°F and 68°F).
  • Avoid fully discharging the battery or leaving it fully charged for extended periods.
  • Do not expose the battery to extreme temperatures or direct sunlight.
• Tires: Check tire pressure before each ride and inflate to the recommended PSI. Inspect tires for wear, cuts, or punctures.
• Brakes: Regularly check brake pads for wear and replace them when necessary. Ensure brake levers are firm and responsive. Adjust brake cable tension as needed.
• Chain: Keep the chain clean and lubricated to ensure smooth shifting and prevent premature wear.
• Bolts and Fasteners: Periodically check all bolts, nuts, and quick-release levers 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 repairs or adjustments, especially involving the motor or electrical system, consult a qualified e-bike technician.

8. Troubleshooting

Here are some common issues and their potential solutions:

• E-bike not powering on:
  • Check if the battery is properly inserted and locked.
  • Ensure the battery is charged.
  • Verify all cable connections to the display and motor are secure.
• Motor not providing assistance:
  • Check the PAS level on the display; ensure it's not set to '0'.
  • Ensure brake levers are not partially engaged, as they often cut motor power.
  • Look for any error codes on the P860ML display and consult the display manual for their meaning.
• Brakes squealing or feeling weak:
  • Clean brake rotors and pads with a specific disc brake cleaner.
  • Check brake pad wear; replace if worn out.
  • Adjust brake cable tension or bleed hydraulic brakes (if applicable, professional service recommended).
• Gears not shifting smoothly:
  • Check for a bent derailleur hanger.
  • Ensure the chain is clean and lubricated.
  • Adjust derailleur limit screws and cable tension (professional service recommended if unsure).
• Unusual noises:
  • Inspect for loose components (bolts, spokes, fenders).
  • Check for rubbing parts (e.g., brake pads rubbing on rotors).

9. User Tips

• Battery Replacement: If you need a replacement battery, ensure you note the exact specifications (48V 20Ah Samsung 50GB Cell) to ensure compatibility and optimal performance. Contact VARSTROM support for genuine replacement parts.
• Local Regulations: Always be aware of and comply with local regulations regarding e-bike speed limits, helmet laws, and where you can ride.
• Pre-Ride Check: Make it a habit to perform a quick safety check before every ride. This includes checking tire pressure, brake function, and battery level.
