Fafrees F20 Flex Long-Range Folding Commuter Electric Bike

Compact Folding Design for Modern Urban Life The Fafrees F20 Flex is designed for riders who want comfort, practicality, and a natural riding experience in everyday city life. With its compact folding structure, responsive torque sensor, and long-range removable battery, this e-bike is ideal for commuting, apartment living, office storage, and weekend rides. Built for convenience without sacrificing comfort, the F20 Flex combines smooth electric assistance with space-saving portability. Torque Sensor for a More Natural Riding Feel Unlike traditional cadence systems, the dual-side torque sensor responds directly to your pedaling force, delivering smoother acceleration and more precise support. This creates a natural riding sensation that feels closer to a traditional bicycle while improving low-speed control and riding efficiency. Whether starting at traffic lights or navigating crowded city streets, the assistance feels smooth, responsive, and intuitive. Long-Range Removable Battery The removable lithium-ion battery is available in two capacities to suit different riding needs. The 36V 20Ah battery provides a range of approximately 75–100 km, while the larger 36V 25Ah battery extends the range to 95–120 km. Built with advanced 21700 battery cells and protected with IPX5 water resistance, the battery is designed for reliable everyday use. The removable design also makes charging more convenient at home or in the office. Smooth and Efficient 250W Motor The rear-drive 250W motor delivers stable and comfortable assistance for city riding. With a peak power of 430W and 43Nm of torque, the F20 Flex handles urban roads and moderate slopes with ease while maintaining a smooth riding experience. The maximum assisted speed of 25 km/h fully complies with EU regulations. Comfort-Focused Urban Riding Daily commuting becomes more comfortable thanks to the front suspension system and suspension seatpost. The 40 mm front suspension helps reduce road vibrations, while the 15 mm travel suspension seatpost improves comfort on uneven city streets and longer rides. Combined with the ergonomic saddle and wide tires, the F20 Flex is built to keep rides smooth and relaxed. 3-Step Folding System for Easy Storage The frame, handlebar stem, and pedals fold quickly in three simple steps, allowing the bike to fit easily into apartments, elevators, offices, or car trunks. This makes the F20 Flex a perfect choice for urban riders who need both mobility and compact storage. Reliable Shimano 7-Speed Drivetrain The Shimano 7-speed transmission system delivers smooth and precise shifting across different riding conditions. Whether riding through city traffic or climbing moderate hills, it provides flexible gearing and improved riding control. Puncture-Resistant Tires for Everyday Reliability The Chaoyang 20 × 2.5 tires are designed with puncture-resistant protection for improved durability and reduced maintenance. They also provide enhanced stability and grip for safer urban riding. Safe and Visible Day or Night Integrated front and rear lights with brake light functionality improve visibility and rider safety in low-light conditions. Mechanical disc brakes with 160 mm rotors provide reliable stopping power for daily riding. Designed for Everyday Practicality The F20 Flex comes fully equipped with practical accessories including a rear rack, fenders, kickstand, and foldable pedals, making it ready for commuting and daily travel right out of the box.
