3. Setup Guide
3.1 Unpacking and Initial Assembly
Your SMARTGYRO eBike comes partially assembled. Carefully remove all packaging materials. You may need to attach the handlebars, pedals, and front wheel. Refer to the included assembly diagram for detailed steps.
3.2 Battery Charging
- Locate the charging port on the battery.
- Connect the charger (included) to the battery port, then plug the charger into a standard electrical outlet.
- The indicator light on the charger will show the charging status (typically red for charging, green for fully charged).
- A full charge takes approximately 5 hours. Do not overcharge the battery.
- Always charge the battery in a well-ventilated area, away from flammable materials.
3.3 Adjusting Seat and Handlebars
- Seat Height: Adjust the seat height so that your leg is slightly bent at the knee when the pedal is at its lowest point. Use the quick-release lever or a wrench to loosen, adjust, and tighten the seat post.
- Handlebar Position: Adjust the handlebar height and angle for a comfortable riding posture. Ensure all bolts are securely tightened after adjustment.
3.4 Pre-Ride Safety Checks
Before each ride, perform the following checks:
- Tires: Check tire pressure. Ensure tires are inflated to the recommended PSI (usually indicated on the tire sidewall).
- Brakes: Test both front and rear brakes to ensure they engage properly and stop the bike effectively.
- Lights: Verify that the front headlight and rear brake light are functioning.
- Bolts and Quick Releases: Ensure all critical bolts (wheels, handlebars, seat post) and quick-release levers are securely fastened.
- Battery: Confirm the battery is securely seated and sufficiently charged.
4. Operating Instructions
4.1 Powering On/Off
To turn on the eBike, press and hold the power button on the handlebar display until the screen illuminates. To turn off, press and hold the power button again until the display turns off.
4.2 Riding Modes
Your eBike offers two main riding modes:
- Paseo Mode (Leisure Mode): This mode provides minimal or no electric assistance, allowing you to ride the bike like a traditional bicycle.
- Pedal Assist Mode: The motor provides assistance as you pedal. The level of assistance can typically be adjusted using the '+' and '-' buttons on the handlebar display. The maximum speed for pedal assistance is 25 km/h.
4.3 Gear Shifting
The SMARTGYRO eBike is equipped with a Shimano 6-speed gear system. Use the shifter on the right handlebar to change gears. Shift to lower gears for climbing hills and higher gears for flat terrain or downhill riding. Always shift gears while pedaling lightly to ensure smooth transitions and prevent damage to the drivetrain.
4.4 Braking
The eBike features front and rear disc brakes. The left lever controls the rear brake, and the right lever controls the front brake. Apply both brakes simultaneously and smoothly for effective and safe stopping. Avoid sudden, hard braking, especially with the front brake, as this can lead to loss of control.
4.5 Using Lights
The integrated front headlight and rear brake light enhance your visibility. The front light can typically be turned on/off via a button on the handlebar display or the light itself. The rear light illuminates when brakes are applied.
5. Maintenance
Regular maintenance is crucial for the longevity and safe operation of your eBike.
5.1 Battery Care
- Charge the battery regularly, even if not in use, to maintain its health.
- Store the battery in a cool, dry place, away from direct sunlight and extreme temperatures.
- Avoid completely draining the battery before recharging.
- If storing for an extended period, charge the battery to about 50-70% and check it every few months.
5.2 Tire Maintenance
- Check tire pressure before each ride and inflate to the recommended PSI.
- Inspect tires for wear, cuts, or embedded objects.
5.3 Brake System
- Regularly check brake pads for wear and replace them if necessary.
- Ensure brake levers have proper tension and engage smoothly.
- Inspect disc rotors for damage or warping.
5.4 Drivetrain (Chain and Gears)
- Keep the chain clean and lubricated to ensure smooth gear changes and prevent rust.
- Inspect gears and derailleur for alignment and damage.
5.5 Cleaning
Clean your eBike regularly with a damp cloth and mild soap. Avoid using high-pressure washers directly on electrical components or bearings. Dry thoroughly after cleaning.
