Assembly Instructions
Before your first ride‚ careful assembly is crucial for safety and performance. This section guides you through handlebar and stem installation‚ ensuring proper alignment and secure tightening. Next‚ we cover wheel and tire mounting‚ emphasizing correct tire pressure and brake alignment.
Pedal attachment requires identifying left and right pedals and tightening them securely. Double-check all bolts and connections before riding. A complete inspection‚ referencing the provided diagrams‚ guarantees a smooth and safe riding experience. Consult a professional if unsure about any assembly step.
Handlebar and Stem Installation
Begin by loosening the stem clamp bolts. Carefully insert the handlebar into the stem‚ centering it to your desired riding position. Tighten the clamp bolts gradually and evenly‚ following the torque specifications outlined in the full Aima Big Sur user manual.
Ensure the handlebar is securely fastened before proceeding. Verify proper alignment with the front wheel. Incorrect installation can compromise steering control and safety. Double-check all bolts after the initial ride and periodically thereafter. Refer to diagrams for visual guidance.
Wheel and Tire Mounting
Before mounting‚ inspect tires for damage. Align the wheel with the frame dropouts‚ ensuring the disc brake rotor (if equipped) slides smoothly into the caliper. Secure the wheel using the appropriate axle nuts or quick-release lever‚ tightening to the specified torque.
Verify the wheel spins freely without rubbing; Inflate tires to the recommended pressure indicated on the tire sidewall. Proper inflation is crucial for performance and safety. Regularly check tire pressure and inspect for wear. Consult the Aima Big Sur manual for detailed instructions.
Pedal Attachment
Identify the left and right pedals – they are marked ‘L’ and ‘R’. The right pedal screws in clockwise‚ while the left pedal screws in counter-clockwise. Apply grease to the pedal threads before installation to prevent seizing.
Using a wrench‚ firmly tighten the pedals into the crank arms. Ensure they are securely attached before riding. Periodically check pedal tightness‚ especially after initial rides. Refer to the Aima Big Sur manual for torque specifications. Correct pedal attachment is vital for safe and efficient cycling;
Operation and Riding
Before each ride‚ ensure the battery is charged and the tires are properly inflated. Power on the Aima Big Sur using the display panel. Select your desired assistance level – lower levels conserve battery‚ higher levels provide more power. Familiarize yourself with the braking system for controlled stops.
Always wear a helmet and adhere to local traffic laws. Practice in a safe area before tackling challenging terrain. The Aima e-bike offers a smooth‚ assisted riding experience. Refer to the manual for detailed instructions on system reset and optimal performance.
Powering On and Off
To power on your Aima Big Sur‚ locate the power button on the display panel. Press and hold the button for approximately two seconds until the display illuminates.

Ensure the bike is stationary when powering on or off. A fully charged battery is recommended for optimal startup. Refer to the manual for troubleshooting display errors. Proper shutdown conserves battery life and prevents potential system issues.
Assistance Levels and Usage

Experiment with each level to find your preference. Remember that higher assistance levels consume more battery power. Utilize the throttle (if equipped) for bursts of power or when starting from a standstill. Always prioritize safe riding practices and adjust assistance based on conditions.
Braking System Operation
Your Aima Big Sur is equipped with a high-performance braking system‚ crucial for safe operation. Familiarize yourself with both brake levers – typically located on the handlebars. Apply both levers simultaneously for optimal stopping power‚ especially at higher speeds or during descents.
Avoid sudden‚ forceful braking‚ which can lead to skidding. Regularly inspect brake pads for wear and tear. Ensure brake cables are properly adjusted and functioning smoothly. Remember that regenerative braking may contribute to slowing down‚ enhancing overall control and efficiency.

Battery Charging and Storage
Proper battery care is crucial for maximizing the lifespan and performance of your Aima Big Sur’s power source. Always use the provided Aima charger. Charge the battery fully before initial use and after extended storage periods. Avoid overcharging; disconnect once complete.
For long-term storage‚ charge to approximately 50-60% and store in a cool‚ dry place. Avoid extreme temperatures. Regularly check the battery’s condition and address any swelling or damage immediately. Refer to the full manual for detailed safety guidelines.
Chain and Gear Maintenance
Regular chain maintenance ensures smooth shifting and extends the life of your Aima Big Sur’s drivetrain. Clean the chain every 100-200 miles‚ or more frequently in wet or dusty conditions‚ using a bicycle-specific degreaser. After cleaning‚ apply a high-quality bicycle chain lubricant.
Inspect gears for wear and damage. Ensure proper shifting adjustment. A well-maintained drivetrain minimizes effort and maximizes efficiency. Consult the complete Aima Big Sur user manual for detailed instructions and recommended products for optimal performance and longevity.
Tire Inflation and Inspection
