Responsive assistance for everyday riding. The F20 Flex 25Ah pairs a 250W rated rear-hub motor with torque-sensor pedal assistance and Shimano 7-speed gearing. The torque sensor responds to your pedalling effort, while the 20 x 2.5-inch wheels give this folding bike its distinctive stance. The frame, handlebar and pedals fold for storage; check the 108 x 45 x 77 cm folded dimensions and 27.2 kg bike weight against your available space and lifting needs.
A removable 25Ah battery. This version carries a 36V 25Ah lithium-ion battery with 900Wh of rated energy. You can remove it for charging with the compatible supplied charger. Allow approximately 8–10 hours for charging. The manufacturer estimates 95–120 km per charge, but hills, rider load, weather and assistance settings affect real-world distance. Plan your route around your own measured range rather than assuming the maximum figure.
Comfort, equipment and control. A 40mm suspension fork with lockout and a 15mm suspension seatpost help cushion the ride; this model does not use a rear frame shock. Mechanical disc brakes, front and rear lights, a rear rack, fenders and a kickstand complete the everyday equipment. The recommended rider-height range is 165–198 cm, with a 140 kg maximum load. Follow the manual for assembly and pre-ride checks, and check the rules for your riding location.
