3. Setup and Assembly
Your Cybervelo EK12 electric bike arrives approximately 90% pre-assembled. Follow these steps to complete the assembly:
3.1 Unpacking
- Carefully remove the bike from its packaging.
- Remove all protective wrapping and ties.
- Inspect the bike for any shipping damage. Contact customer support immediately if damage is found.
3.2 Handlebar Installation
Attach the handlebar stem to the fork steerer tube. Ensure the handlebars are centered and the stem bolts are tightened securely. Adjust the angle for comfortable riding.
3.3 Pedal Installation
Identify the left (L) and right (R) pedals. The left pedal tightens counter-clockwise, and the right pedal tightens clockwise. Apply a small amount of grease to the threads before installation. Tighten firmly with a wrench.
3.4 Seat Adjustment
Insert the seat post into the frame. Adjust the seat height so your feet can comfortably touch the ground when stopped, or your leg has a slight bend at the knee when the pedal is at its lowest point. Secure the quick-release lever firmly.
3.5 Tire Inflation
Check the recommended tire pressure (PSI) on the tire sidewall. Inflate tires to the specified range using a bicycle pump.
3.6 Initial Battery Charge
Before your first ride, fully charge the battery. Connect the charger to the battery charging port and then to a power outlet. The indicator light on the charger will change when fully charged (typically 6-7 hours).

4.7 Folding and Unfolding
To fold the bike, open the frame hinge quick-release lever and fold the frame in half. The handlebars and pedals can also be folded for a more compact size. Reverse the process to unfold, ensuring all quick releases are securely fastened before riding.
4.8 Headlight and Taillight
The integrated headlight and taillight provide visibility during low-light conditions. The headlight can be controlled via the LCD display. Ensure lights are functional before riding at dawn, dusk, or night.
5. Maintenance
Regular maintenance ensures the longevity and safe operation of your e-bike.
- Cleaning: Clean the bike regularly with a damp cloth. Avoid high-pressure washing directly on electrical components.
- Tire Pressure: Check tire pressure weekly and maintain it within the recommended PSI range (found on the tire sidewall).
- Brakes: Inspect brake pads for wear and adjust brake cables as needed to ensure responsive braking.
- Chain: Lubricate the chain every 100-200 miles or after riding in wet conditions. Keep it clean and free of rust.
- Battery Care: Charge the battery after each ride. If storing the bike for an extended period, charge the battery to 50-70% and recharge every 1-2 months. Store in a cool, dry place.
- Fasteners: Periodically check all bolts, nuts, and quick releases for tightness.
6. Troubleshooting
Here are some common issues and their potential solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Bike does not power on | Battery not charged or not properly seated; loose electrical connection. | Ensure battery is fully charged and securely inserted. Check all visible cable connections. |
| Motor not assisting | Low battery; PAS level set to 0; brake levers engaged; motor error. | Charge battery. Increase PAS level. Ensure brake levers are fully released. Check LCD for error codes. |
