6. Operating Instructions
The Jasion YR16 offers multiple riding modes to suit various preferences and conditions:

Image 6.1: Available Riding Modes.
- Pedal Mode: Ride the bike like a traditional bicycle, using only your leg power.
- Pedal-Assist Mode (PAS): The motor provides assistance as you pedal. The level of assistance can be adjusted via the LCD display. This mode offers the longest range.
- Throttle Only Mode: Engage the throttle to propel the bike without pedaling. This mode consumes battery power more quickly.
- Cruise Control: The integrated cruise control feature maintains a steady speed, reducing wrist strain on longer rides. Activate and deactivate via the controls on the handlebar.
- Walk-Assist Mode: Provides low-speed motor assistance to help you push the bike when walking alongside it.
To power on the bike, press and hold the power button on the LCD display. Use the control buttons near the display to switch between assist levels, activate cruise control, and view ride data.
7. Battery Management
7.1. Charging
To charge the battery, you can either leave it installed on the bike or remove it for charging indoors. Connect the charger to the battery's charging port and then plug the charger into a standard wall outlet. The charger's indicator light will show the charging status (typically red for charging, green for fully charged). Charging time is approximately 4-6 hours.
7.2. Battery Care
- Avoid fully discharging the battery regularly.
- Store the battery in a cool, dry place when not in use.
- Charge the battery at least once every two months, even if not in use, to maintain its health.
