5. Operating Instructions
5.1 Powering On and Off
To turn on the bike, first ensure the battery is turned on by pressing the red button beside the battery. Then, long press the 'M' button on the handlebar display. To turn off, long press the 'M' button again.
5.2 Riding Modes
The Wheelspeed ARIES offers two primary riding modes:
- Pure Electric Mode: Use the throttle (located on the handlebar) to engage the motor and propel the bike without pedaling. This mode is ideal for quick acceleration or when you prefer not to pedal.
- Pedal Assist Mode (PAS): As you pedal, the motor provides assistance, making riding easier, especially uphill or over long distances. The faster you pedal, the stronger the motor's boost. The bike features a 5-level LCD display to adjust the pedal assist level. The default gear is 0; you must change gears for the motor to engage in PAS mode.
5.3 Battery Operation and Charging
The bike is equipped with a 48V 11.6Ah removable battery. It provides a range of 50-56 miles with pedal assist or 25-30 miles on pure electric power. The battery can be charged directly on the bike or removed for convenient charging indoors. A full charge typically takes 6 hours.
5.4 Display and Controls
The handlebar features a 5-level LCD display that shows current speed, battery life, odometer, and pedal assist level. Controls for adjusting assist levels, activating the headlight, and the horn are easily accessible.
5.5 Switching Speed Units (MPH/KM/H)
To switch the speed unit on the display between MPH and KM/H:
- Long press the "^" and "V" buttons together.
- Then, press the "M" button once.
- Press "^" or "V" button to switch between MPH and KM/H.
- Press the "M" button again to confirm your selection.
6. Maintenance
Regular maintenance is crucial for the longevity and performance of your Wheelspeed ARIES electric bike.
- Cleaning: Clean the bike regularly with a damp cloth. Avoid high-pressure washing directly on electrical components.
- Battery Care: Do not overcharge the Lithium Ion battery. Disconnect the charger once the battery is full. Store the battery in a cool, dry place, away from extreme temperatures.
- Tires: Check tire pressure before each ride. The tires are not thornproof; consider installing liners for added protection.
- Brakes: Regularly inspect brake pads and rotors for wear. Ensure brakes are responsive and adjust if necessary.
- Chain and Gears: Keep the chain clean and lubricated. Periodically check the 7-speed transmission system for smooth operation.
- Fasteners: Periodically check and tighten all bolts and screws, especially on critical components like the handlebars, wheels, and seat post.
7. Troubleshooting
This section addresses common issues you might encounter with your Wheelspeed ARIES electric bike.
| Problem | Possible Cause | Solution |
|---|---|---|
| E-bike does not power on. | Battery is off or discharged; 'M' button not long-pressed. | Ensure the red button beside the battery is pressed to turn it on. Long press the 'M' button on the display. Charge the battery if it's low. |
| Motor does not engage in Pedal Assist Mode. | Default gear is 0; gears not switched. | Press "^" or "V" button to switch gears from 0 to a higher level (e.g., 1-5) to engage the motor. |
| Speed unit (MPH/KM/H) is incorrect. | Unit setting needs adjustment. | Long press "^" and "V" buttons together, then press "M" once. Use "^" or "V" to select unit, then "M" to confirm. |
| Reduced battery range. | High PAS level usage; extreme temperatures; wind resistance; hills. | Use lower PAS levels to conserve battery. Optimal battery temperature is 45-75 degrees Fahrenheit. These factors naturally reduce range. |
| Uncomfortable seat. | Stock seat design. | Consider replacing the stock seat with an aftermarket comfort seat (e.g., gel or memory foam). |
