Setup

1. Unpacking and Initial Assembly

Your Fafrees 20F054 bike comes mostly pre-assembled. Carefully remove all packaging materials. You may need to attach pedals, adjust the handlebars, and seat post.

• Unfold the bike frame and secure the folding mechanism.
• Attach the pedals, ensuring they are tightened correctly (left pedal is reverse threaded).
• Adjust the handlebar height (103 cm to 117.5 cm) and angle for comfortable riding.
• Adjust the seat post height (70 cm to 107 cm) to ensure your feet can comfortably touch the ground when stopped.

2. Battery Installation and Initial Charge

The removable battery is located under the standard rear rack. For optimal performance, fully charge the battery before its first use.

• Ensure the bike is powered off.
• Remove the battery from its compartment (if not already installed).
• Connect the charger to the battery charging port, then plug the charger into a power outlet.
• The charging indicator on the charger will change (e.g., from red to green) when fully charged. A full charge typically takes 5-6 hours.
• Once charged, reinstall the battery securely into its compartment.
