Folding step-through e-bike that fits anywhere Apartment too small? Car trunk too tight? The F20 Flex folds at frame, stem, and pedals in seconds. This folding step-through e-bike slides under desks or into closets, and the open frame means no more awkward leg swings — just step on and go.
Dual-side torque sensor = feels like a normal bike, only faster No jerky starts. No guessing. A dual-side torque sensor reads how hard you pedal and sends exactly the power you need. That’s why this pedal assist e-bike gives you smooth low-speed control in traffic and support on hills — like having a gentle tailwind all the time.
Big removable battery for 100km of real-world riding The removable 36V 20Ah battery (720Wh) locks in place, pops out for indoor charging, and delivers up to 100km per charge. With 3A fast charging (~8 hours) and IPX5 protection, this long range electric bike laughs at range anxiety — commute all week or explore all day.
Dual suspension + puncture-resistant tires = comfort you’ll feel City streets are rough. Your ride shouldn’t be. Dual suspension (40mm fork + 15mm seatpost) eats potholes and cobblestones, while 20×2.5" puncture-resistant tires block flats and grip wet pavement. This electric city bike turns bone-rattling roads into a smooth cruise.
7-speed gears, disc brakes, and everything included No hidden costs. The bike comes with 7-speed Shimano gearing, mechanical disc brakes, a padded rear rack, full fenders, front & rear lights, and even a gift box (tube, brake pads, multi-tool). Plus 6km/h walk assist for pushing up ramps. It’s the most ready-to-ride folding electric bike。
