F20 Flex – The Smart Folding E-Bike for Everyday Urban Life
F20 Flex is a versatile folding step-through electric bike designed for modern city living. Combining compact storage, comfortable riding, and reliable electric assistance, it is an ideal solution for daily commuting, errands, leisure rides, and apartment-friendly transportation. With its thoughtful design and practical features, the F20 Flex makes cycling more accessible and convenient for riders of all experience levels.
One of the standout features of the F20 Flex is its innovative three-point folding system. The frame, handlebar stem, and pedals can all be folded, allowing the bike to become significantly more compact when not in use. This makes it easy to store in apartments, offices, small storage spaces, or vehicle trunks. Whether you need to take the bike on a trip or simply save space at home, the folding design helps reduce everyday storage challenges.
The bike features an open step-through frame that prioritizes accessibility and comfort. Riders can easily get on and off without needing to lift a leg high over the frame, making it especially convenient when wearing everyday clothing. This beginner-friendly design supports a relaxed riding experience and appeals to commuters, casual riders, and anyone seeking greater comfort.
Powering the F20 Flex is a 250W rear hub motor that delivers smooth and dependable assistance for city riding. The motor supports speeds up to 25 km/h in EU-legal configuration and provides up to 43 Nm of torque, helping riders tackle city streets, gentle hills, and daily commuting routes with confidence. To enhance ride quality, the bike incorporates a dual-side torque sensor that measures pedaling effort and adjusts motor support accordingly. This results in a more natural riding feel, smoother acceleration, and improved control during stop-and-go urban traffic.
The F20 Flex is equipped with a high-capacity removable 36V 25Ah lithium battery designed for long-distance use. Under suitable riding conditions, the battery can provide a claimed range of approximately 95 to 120 kilometers on a single charge. Built with advanced 21700 battery cells, it offers dependable performance while remaining removable for convenient charging. A built-in battery lock adds security, and the battery system is designed to withstand everyday riding conditions with IPX5 protection. Charging is supported through a 3A fast charger, with a full charge taking approximately 10 hours.
Comfort is another major focus of the F20 Flex. The bike features a front suspension fork with 40 mm of travel and a suspension seatpost with 15 mm of travel. Together, these components help absorb road vibrations and bumps, creating a smoother and more enjoyable ride on uneven city streets. Complementing this setup are 20 × 2.5-inch puncture-protected tires that provide stability, comfort, and reliable grip while helping reduce the likelihood of flats.
Additional commuter-friendly features include a color display with speed, battery status, and pedal-assist information, 7-speed gearing for versatile riding, front and rear disc brakes for dependable stopping power, and a complete accessory package. The included rear rack with cushion, front and rear fenders, front light, and rear brake light make the F20 Flex ready for everyday use straight out of the box. Combining practicality, comfort, and smart urban mobility, the F20 Flex is built to simplify daily transportation and enhance every ride.
