Compact Folding Step-Through E-Bike for Apartments & Commutes The F20 Flex is a folding step-through e-bike featuring a three-point folding system (frame, handlebar stem, and pedals) for ultra-compact storage. Ideal for city dwellers, this electric commuter bike easily fits in car trunks, office corners, or small apartments while offering a low step-over height for easy mounting in everyday clothes.
Dual-Side Torque Sensor for Smooth Pedal Assist Equipped with a dual-side torque sensor, this pedal assist e-bike delivers instant, responsive power that matches your pedaling force. Enjoy smoother starts, better low-speed control in stop-and-go traffic, and a more intuitive ride compared to cadence sensors – perfect for beginners and daily urban routes.
Long-Range Removable Battery with 120km Range The removable 36V 25Ah lithium battery (900Wh) powers up to 120km on a single charge, making this long range electric bike a reliable partner for weekly commutes. The battery uses durable 21700 cells, features a lock for security, and charges in 8–10 hours with 3A fast charging – easily take it inside to charge.
Dual Suspension & Anti-Puncture Tires for All-Day Comfort Ride city potholes and rough roads with confidence thanks to dual suspension (40mm travel front fork + 15mm suspension seatpost). The 20×2.5" puncture-resistant tires reduce flat risks while adding grip, giving this electric city bike a smooth, comfortable feel even on longer errands or relaxed rides.
7-Speed Gearing & Commuter-Ready Accessories Shift effortlessly with 7-speed Shimano gearing to tackle gentle climbs and flats at your own pace.
