2.3 Front Wheel and Fender Installation
Install the front fender onto the front fork. Then, carefully align and install the front wheel, ensuring the brake disc is correctly positioned within the caliper. Secure the wheel with the quick-release skewer or axle nuts. Note: The arrow mark on the brake disc should be assembled counterclockwise. Do not use the brake handle before the assembly is completed after removing the yellow gasket from the brake caliper.
2.4 Handlebar and Headlight Attachment
Attach the handlebar to the stem, ensuring it is centered and aligned. Tighten the stem bolts securely. Install the retro headlight onto the front fork and connect its wiring. Note: The black cover and screw on the top need to be used for handlebar assembly. After tightening the top screw, tighten the two screws on the side. Tighten the four screws at the front in the order shown in the video. Avoid uneven locking pressure.

3.2 Riding Modes and Gears
The Likebike U12 offers 3 distinct riding modes and a 7-speed transmission system:
Pedal Assist Mode (PAS): Provides motor assistance as you pedal. This mode offers an impressive range of up to 100 miles depending on load and terrain.
Throttle Mode: Allows you to propel the bike using only the throttle, similar to a motorcycle. This mode offers a range of approximately 50 miles.
Manual Mode: Ride the bike like a traditional bicycle, using only pedal power.
Use the 7-speed gears to adapt to different environments, from city streets to rugged trails or sandy beaches. The 2000W peak brushless motor can reach top speeds of up to 32 mph and easily conquer 35-degree steep slopes.
