Setup and Assembly
Unfolding the Bike
Carefully remove the bike from its packaging. Locate the folding mechanism on the frame. Release the latch and unfold the frame until it locks into place. Secure the handlebar stem in the upright position.
Handlebar and Seat Adjustment
Adjust the handlebars to a comfortable height using the quick-release lever. Ensure the handlebars are aligned with the front wheel. Adjust the seat post height so your feet can comfortably touch the ground when stopped, or slightly touch with toes when pedaling.
Tire Inflation
Check tire pressure before your first ride. Inflate tires to the recommended PSI (usually found on the tire sidewall).
Battery Charging
Before first use, fully charge the battery. Connect the charger to the bike's charging port, then plug it into a power outlet. The indicator light on the charger will change when fully charged.
Operating Instructions
Powering On/Off
Press and hold the power button on the digital display to turn the bike on or off.
Riding Modes
The Aairsk RS5 features multiple riding modes:
- Pedal Assist (PAS) Mode: Provides motor assistance as you pedal. Adjust the assist level using the '+' and '-' buttons on the display.
- Throttle Mode: Engage the throttle for motor power without pedaling.
- Pedal Only Mode: Ride like a traditional bicycle with no motor assistance.
Digital Display
The digital display shows speed, battery level, riding mode, and trip distance. Refer to the display's specific instructions for detailed navigation.
Braking
Apply both front and rear disc brakes smoothly to slow down or stop. Avoid sudden, hard braking, especially at high speeds.
Maintenance
Regular Cleaning
Clean your e-bike regularly with a damp cloth. Avoid using high-pressure water jets directly on electrical components.
Brake Inspection
Regularly check brake pads for wear and ensure brake levers are responsive. Adjust or replace as needed.
Tire Care
Inspect tires for wear, punctures, and proper inflation before each ride.
Battery Care
Store the battery in a cool, dry place when not in use. Charge the battery at least once every three months, even if not used, to maintain its health.
Fastener Check
Periodically check all bolts, nuts, and quick-release levers to ensure they are tight and secure.
