Setup and Assembly
- Unpacking: Carefully remove all components from the packaging. Retain packaging for potential future transport or returns.

Operating Instructions
Powering On/Off
To power on the bike, press and hold the power button on the LCD display. To power off, press and hold the same button until the display turns off.
LCD Display Functions
The smart LCD screen tracks real-time speed, battery level, pedal assist level, mileage, and other statistics. Refer to the display's specific manual for detailed navigation.
Riding Modes
- Pedal Assist Mode: The motor provides assistance as you pedal. Adjust the assist level using the '+' and '-' buttons on the display. Higher levels provide more assistance.
- Throttle Mode: Engage the throttle (if equipped) for motor power without pedaling. This mode is ideal for quick acceleration or maintaining speed without effort.
- Manual Mode: Ride the bike like a traditional bicycle with no motor assistance.
Gears
The bike features a 7-speed gear system. Use the gear shifter on the handlebar to select appropriate gears for different terrains and speeds. Shift smoothly to avoid damage to the drivetrain.
Braking
The EK15 is equipped with disc brakes. Apply both front and rear brakes simultaneously for effective and controlled stopping. Avoid sudden, hard braking, especially at high speeds.
Maintenance
Battery Care
- Charge the battery regularly, even if not in use, to maintain its lifespan.
- Store the battery in a cool, dry place, away from direct sunlight and extreme temperatures.
- Do not fully discharge the battery frequently.
- Use only the original charger provided with the bike.
Tire Maintenance
The bike features puncture-resistant 26-inch tires. Regularly check tire pressure and inflate to the recommended PSI (pounds per square inch) indicated on the tire sidewall. Proper tire pressure ensures optimal performance and prevents flats.
General Cleaning and Inspection
- Clean the bike regularly with a damp cloth. Avoid using high-pressure washers directly on electrical components.
- Inspect all bolts and fasteners periodically to ensure they are tight.
- Lubricate the chain regularly to ensure smooth operation and prevent rust.
- Check brake pads for wear and replace them when necessary.
