Analysis
The F20 Flex has a 3-point folding design (chassis, handlebar and pedals) for compact storage, and a low step-through frame for effortless mounting. The bilateral torque sensor gives a smooth start and controlled low-speed handling.
The 250W rear motor with 43Nm of torque is legally capped at 25 km/h, and the removable 36V 25Ah battery (900Wh) with 21700 cells gives 95 to 120 km of range, with theft protection and IPX5 water resistance. Dual suspension (fork and seatpost) and 20 x 2.5 inch puncture-free tyres provide comfort, with dual disc brakes, a rack, fenders and lights included as standard.
