Video: Comprehensive assembly guide for the ANCHEER Electric Bike, demonstrating each step from unboxing to final checks.
4.1. Install the Handlebar

4.2. Install the Seat
Insert the seat post into the seat tube of the bike frame. Adjust the seat height to a comfortable riding position, ensuring the minimum insertion mark on the seat post is not visible. Secure the seat post by closing the quick-release lever firmly.
4.3. Install the Pedals
Identify the left (L) and right (R) pedals. The right pedal (R) threads clockwise into the right crank arm. The left pedal (L) threads counter-clockwise into the left crank arm. Apply a small amount of grease to the pedal threads before installation. Tighten securely with a wrench.
4.4. Install the Front Wheel
Turn the bike upside down, resting it on the handlebars and seat (use padding under the handlebars to protect the display). Carefully align the front wheel into the fork dropouts, ensuring the disc brake rotor slides correctly into the brake caliper. Insert the quick-release skewer through the hub and tighten it firmly. Ensure the wheel is centered and spins freely without brake friction.

4.6. Install the Battery
Slide the removable 48V 10Ah lithium-ion battery into its housing on the bike frame. Push firmly until it clicks into place. Use the key to lock the battery securely to prevent theft and ensure proper connection during rides. Confirm the battery lock is engaged.

6. Charging the Battery
To charge the battery, first ensure the e-bike is powered off. Connect the charger to the charging port on the battery, then plug the charger into a standard wall outlet. The indicator light on the charger will typically turn red during charging and green when fully charged. Charging time is approximately 4-6 hours. Do not overcharge the battery.
