FAFREES F20 Flex Commuting Ebike With 36V 20Ah Battery / 100km Range, Torque Sensor

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 natural 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。 Specification: Brand:FAFREES MODEL:F20 Flex Type:Folding City Ebike Tire size:20*2.5" Air tire Frame material:Aluminum alloy Default maximum speed of assisted mode:25km/h Default maximum speed of throttle:6km/h Max range:75-100km Max climbing Gradability:15° Battery type:21700 Lithium-ion battery Battery capacity:20Ah/720Wh Motor rated power:250W Motor location:Rear drive Maximum torque:43N.m Charger Input voltage:110-220V Output voltage:42V Rated current:3A charging time:8-10H Fork Type:Shock fork Type of rear shock:Seat shock tube Display type:LCD 6km/h walk assist mode:Yes Cruise control:No APP control:No PAS level:0-3 Speed Sensor:Torque Sensor Transmission:Shimano 7-Speed Brake type:Mechanical disc brakes Folding parts:Folding handlebar, frame, pedals Headlight:Yes Taillight:Yes Operating temperature:（-20）℃-40℃ Waterproof grade:IPX5 Net Weight:26.5kg Package weight:34.8kg Battery weight:3.8kg Load capacity:140kg Unfolded size:164*67*120cm Folded size:108*45*77cm Package size:89*39*75cm Recommend rider heights:165-198cm Package contains 1x F20 Flex ebike 1x Charger 1x Owner's manual 1x Gift box (Including 1*Inner tube, 2*Valve caps, 2*Wheel reflectors, 2*Brake pads, 1*Key chain，1*Multifunctional tool, 1*13/15 Wrench) EU/UK Countries Can be delivered within 4-7 Days.You don't have to pay delivery fee.
