Setup
Before your first ride, proper assembly and initial checks are crucial.
1. Unboxing and Assembly
- Carefully remove all components from the packaging.
- Attach the front wheel, handlebars, pedals, and seat post as per the included assembly guide (refer to diagrams if provided with your physical product).
- Ensure all bolts and quick releases are securely tightened.
2. Battery Installation and Charging
- Locate the battery compartment. Insert the battery securely until it clicks into place.
- Connect the charger to the charging port on the bike or directly to the battery if removed.
- Plug the charger into a standard wall outlet. The indicator light on the charger will show charging status (typically red for charging, green for fully charged).
- Allow 6-8 hours for a full charge before the first use.
3. Pre-Ride Safety Checks
- Tires: Check tire pressure. The recommended pressure is usually indicated on the tire sidewall.
- Brakes: Test both front and rear brakes to ensure they engage smoothly and effectively.
- Handlebars & Seat: Confirm handlebars are straight and tight, and the seat post is at a comfortable height and securely clamped.
- Lights: Verify that the headlight and taillight (if equipped) are functional.
- Quick Releases: Double-check all quick-release levers are closed and secure.

Operating Instructions
Familiarize yourself with the controls and riding modes of your C93 electric bike.
1. Powering On/Off
- To turn on the bike, press and hold the power button on the display panel for a few seconds.
- To turn off, press and hold the power button again until the display shuts down.
2. Riding Modes
- Pedal Assist Mode (PAS): The motor provides assistance as you pedal. Use the '+' and '-' buttons on the display to adjust the level of assistance (e.g., 1-5). Higher levels provide more power.
- Throttle Mode: Engage the throttle (typically on the right handlebar) to propel the bike without pedaling. This mode is ideal for quick acceleration or when you need a break from pedaling.
- Manual Mode: Ride the bike like a traditional bicycle without any motor assistance.
3. Braking
- The C93 is equipped with disc brakes. Apply both front and rear brakes simultaneously for effective and controlled stopping.
- Avoid sudden, hard braking, especially with the front brake, to prevent skidding.
4. Digital Display
The digital display shows important information such as current speed, battery level, assist level, and trip distance. Consult the specific display manual (if provided) for detailed functions.

Maintenance
Regular maintenance ensures the longevity and safe operation of your electric bike.
- Tires: Regularly check tire pressure and inspect for wear or damage. Replace tires when tread is worn.
- Brakes: Inspect brake pads for wear and replace them if necessary. Ensure brake levers are firm and responsive. Adjust brake cables if they feel loose.
- Chain: Keep the chain clean and lubricated, especially after riding in wet or dusty conditions.
- Battery Care:
- Charge the battery regularly, even if not using the bike for extended periods (at least once a month).
- Store the battery in a cool, dry place, away from direct sunlight and extreme temperatures.
- Do not fully discharge the battery frequently, as this can reduce its lifespan.
- Frame & Components: Periodically check all bolts and fasteners for tightness. Clean the frame with a damp cloth; avoid high-pressure washing directly on electrical components.
- Suspension: Inspect the dual shock absorbers for any leaks or damage.
