YTYIN Free Shipping Aluminium Alloy Frame Electric Bike 750w Folding City Ebike

Enjoy compact urban transportation with the YTYIN OEM-BF-004 Folding Electric Bike. Designed for commuting, short-distance travel, recreational riding, and convenient storage, this e-bike combines a folding frame, rear hub motor, rechargeable lithium battery, and compact 20-inch wheels.

The folding design allows the bicycle to occupy less storage space when not in use, making it suitable for apartments, offices, vehicles, and public-transport connections. Electric assistance helps reduce pedalling effort during daily journeys, while the standard pedals allow the bicycle to be used manually when required.

Final motor, battery, brake, drivetrain, frame, and suspension specifications should be confirmed before publishing because the supplied technical information contains several conflicting configurations.
