Setup and Assembly
The Wheelspeed ARIES electric bike comes largely pre-assembled. Follow these steps to complete the assembly and prepare your bike for its first ride. It is recommended to have the bike inspected by a professional bicycle mechanic after assembly to ensure all components are correctly installed and adjusted for safety.
- Unpacking: Carefully remove the bike and all components from the packaging. Retain packaging for future transport or storage.
- Handlebar Installation: Attach the handlebars to the stem, ensuring they are centered and tightened securely.
- Front Wheel Installation: Install the front wheel, ensuring the quick-release skewer or axle nuts are properly tightened. Verify the front disc brake caliper aligns correctly with the rotor.
- Pedal Installation: Identify the left (L) and right (R) pedals. Thread the pedals into the crank arms by hand, then tighten securely with a wrench. Note that the left pedal has a reverse thread.
- Seat Post and Saddle: Insert the seat post into the frame and adjust the saddle height to your comfort. Secure the quick-release lever or bolt.
- Fenders and Headlight: Attach the front and rear fenders and the headlight as per the included accessory instructions.
- Battery Installation: Insert the battery into its designated slot on the frame and lock it securely with the key.
- Tire Inflation: Inflate both tires to the recommended pressure indicated on the tire sidewall. A pump is typically included with the bike.
- Final Checks: Double-check all bolts, nuts, and quick-release levers for tightness. Test the brakes and gear shifting before your first ride.
Operating Instructions
Understanding how to operate your Wheelspeed ARIES electric bike will ensure a safe and enjoyable riding experience.
Turning On/Off
- To turn on the e-bike, first ensure the battery is securely installed and turn on the battery using the red button located beside it.
- Next, long press the "M button" on the handlebar display to power on the e-bike system.
- To turn off the e-bike, long press the "M button" again until the display powers down.
Riding Modes
Your Wheelspeed ARIES electric bike offers two primary riding modes:
- Pure Electric Mode (Throttle Only): In this mode, you can use the throttle to propel the bike without pedaling. The motor will drive the e-bike directly.
- Pedal Assist Mode (PAS): This is a hybrid mode where the motor provides assistance as you pedal. The faster you pedal, the stronger the power boost from the motor. You can adjust the level of assistance using the display controls.
Gear Shifting
The bike is equipped with a 7-speed Shimano transmission system. Use the "∧" (up) or "∨" (down) buttons on the handlebar shifter to change gears. Note: The default gear on the display is 0. You must select a gear (1-7) for the motor to engage in pedal assist mode.
LCD Display Functions
The 5-level LCD display provides important information during your ride:
- Speed: Current riding speed.
- Battery Level: Indicates the remaining battery charge.
- PAS Level: Shows the current pedal assist level (0-5).
- Odometer: Tracks total distance traveled.
- Headlight Indicator: Shows if the headlight is on.
Battery Management
Proper battery care is crucial for maximizing the lifespan and performance of your e-bike's battery.
- Charging: The 48V 11.6Ah battery can be charged directly on the bike or removed for convenient charging indoors. A full charge typically takes approximately 6 hours. Always use the original charger provided with your bike.
- Avoid Overcharging: While modern batteries have protection, it is good practice to disconnect the charger once the battery is fully charged to prolong its life.
- Temperature: For optimal performance and longevity, store and charge the battery within a temperature range of 7°C to 24°C (45°F to 75°F). Extreme temperatures can affect battery capacity and lifespan.
- Storage: If storing the bike for an extended period, charge the battery to about 50-60% and store it in a cool, dry place. Recharge it every 1-2 months to prevent deep discharge.
This diagram illustrates the various protective features of the battery's Battery Management System (BMS), including overcharge, over-discharge, short circuit, temperature, and current protection, ensuring safe and reliable operation.
Maintenance
Regular maintenance will keep your Wheelspeed ARIES electric bike in optimal condition and extend its lifespan.
- Cleaning: Clean your e-bike regularly with a damp, soft cloth. Avoid using high-pressure washers directly on electrical components.
- Tires: Check tire pressure before each ride and inflate to the recommended PSI. Inspect tires for wear, cuts, or punctures.
- Brakes: Regularly check brake lever tension and brake pad wear. Adjust or replace pads as needed. Ensure disc rotors are clean and free of oil.
- Chain: Keep the chain clean and lubricated to ensure smooth gear changes and prevent wear.
- Bolts and Fasteners: Periodically check and tighten all bolts, nuts, and quick-release levers, especially on critical components like handlebars, wheels, and seat post.
- Professional Inspection: It is recommended to have your e-bike professionally inspected by a qualified bicycle mechanic at least once a year, or more frequently if you ride often or in challenging conditions.
