7. Twist Throttle Malfunction
Check if the connection wires are loose or detached (if not, it may indicate a faulty twist throttle, replace the twist throttle).

Tools Needed: Needle-nose pliers, hex wrench, replacement brake pads.

1. Removing the Brake Pads

a. Prepare the bike for maintenance. Start by turning off the bike and removing the battery.

b. Locate the brake pads. The brake pads are located inside the brake caliper on each wheel (refer to the photo).

c. Begin by removing the brake caliper. Use a hex wrench to remove the two brake caliper bolts from the bike frame (caution: be careful not to lose or misplace the washers inside the brake caliper bolts).

d. Carefully straighten the retaining pin with needle-nose pliers to remove the brake caliper bolts. Push up on the brake caliper.

e. Remove the old brake pads. Depress the spring plate to release the retaining pins and old brake pads.

2. Installing Brake Pads

a. Install the new brake pads into the brake caliper. Assemble the brake pads in the same configuration as the old ones. The friction material should be facing each other. Ensure that the top holes of each pad align with the retaining pin holes. Slide the new brake pads into the caliper to complete the installation.

b. Replace the brake pad retaining pins. Carefully bend the retaining pins to a 90° angle with needle-nose pliers to secure the brake caliper.

c. Reinstall the caliper. Position the caliper, aligning the mounting holes on the frame with the mounting points on the caliper. Insert the bolts with a hex wrench and tighten them evenly.

d. Before riding, reinstall the battery and test the brakes to ensure proper installation.

Tip: The best way to maintain brakes is to use both brakes simultaneously and engage the rear brake first to avoid excessive front wheel and fork tightening.

Brake adjustment includes:

· Check the wheels to ensure they are securely fastened in the frame dropouts. Improper wheel installation can cause the brake rotor to rub against the brake pads and create noise.

· Inspect the brake rotor for flatness and good condition. Damaged or dirty brake rotors can result in decreased braking performance or noise.

· Center the brake caliper by adjusting its positioning, bringing the inner pad (fixed part of the brake caliper) close to and parallel with the brake rotor. Incorrect brake pad or caliper positioning can lead to decreased braking performance or noise.

· Adjust the brake cable tension and check the brake lever. These final adjustments will help ensure properly adjusted brakes.

Prepare the bike for maintenance. Remove the battery and hold the power button for 10 seconds to discharge any remaining power.

1. Start by removing the left crank arm. Loosen the bolt with a hex wrench, then insert a crank puller tool to remove the crank arm.

2. Follow the same steps for the right-side crank arm, first remove the bolt with a hex wrench, then insert the crank puller tool into the opening.

3. Test the chain after installing the new crankset. The bike needs to be supported on a stand to elevate the rear wheel, and the crank must be rotated backward to rotate the rear wheel. Ensure the chain is properly connected to the chainrings.
