4.5 Shifting Gears
The tricycle features a Shimano 7-speed gear system. Use the twist grip shifter on the handlebar to change gears. Shift to lower gears for climbing hills and higher gears for flat terrain or downhill riding.

4.6 Braking System
The Skeri ET03 is equipped with high-performance front and rear hydraulic disc brakes for reliable stopping power. It also features a hydraulic parking brake for secure parking.
- Engaging Brakes: Squeeze the brake levers on the handlebars to activate the disc brakes. Apply both brakes simultaneously for balanced stopping.
- Parking Brake: To engage the parking brake, squeeze the brake lever and then activate the parking lock mechanism (usually a small lever or button on the brake lever). Ensure the tricycle is stable before dismounting.

4.7 Differential System
The innovative rear hub and differential system allow the rear wheels to spin at different speeds, providing superior maneuverability and stability, especially during turns. This reduces the risk of tipping compared to standard trikes.

5. Maintenance
Regular maintenance ensures the longevity and safe operation of your Skeri Electric Tricycle ET03.
- Tires: Check tire pressure before each ride. The 20"x4" fat tires require specific pressure, usually indicated on the tire sidewall. Inspect for wear and punctures.
- Brakes: Regularly check brake pads for wear and ensure brake levers provide firm, responsive stopping power. Adjust or replace as needed.
- Chain: Keep the chain clean and lubricated to prevent rust and ensure smooth shifting.
- Fasteners: Periodically check all bolts, nuts, and screws for tightness. Loose fasteners can lead to unsafe conditions.
- Battery: Keep battery contacts clean. Avoid storing the battery fully discharged. Charge it regularly, even if not in use, to maintain battery health.
- Cleaning: Clean the tricycle with a damp cloth. Avoid using high-pressure washers directly on electrical components.
