Product Description
The FAFREES F20 Flex is a folding electric bike designed for urban commuting and apartment storage. With its three‑point folding system, low‑step frame, dual‑side torque sensors, long‑range removable battery, and dual suspension, it makes daily rides easy and comfortable – the ideal companion for city life and short trips.
I. Space‑Saving, Flexible Folding
The F20 Flex features a three‑point folding system – frame, stem, and pedals are all foldable. When folded, it measures just 108×45×77 cm, fitting easily into a car boot, under a desk, or in a corner of an apartment. The aluminium alloy frame is lightweight yet strong; the bike weighs 26.5 kg and supports a max load of 140 kg.
II. Low‑Step Frame, Easy Mounting
The open low‑step frame makes mounting and dismounting easy, even in everyday clothing. No high leg lifts – ideal for beginners and those seeking comfort. The saddle height (87‑100 cm) and handlebar height (109‑120 cm) are adjustable for riders from 165‑198 cm tall.
III. Torque Sensor
Unlike traditional cadence sensors, the F20 Flex is equipped with dual‑side torque sensors that measure pedalling force in real time and deliver proportional assistance. Smoother starts, precise low‑speed control – in stop‑and‑go city traffic, the ride feels like a extension of your body.
IV. Dual Suspension, Comfortable Ride
City roads can be uneven; the F20 Flex features a 40mm‑travel suspension fork and a 15mm‑travel suspension seatpost that effectively absorb road vibrations. The 20×2.5" puncture‑resistant tyres offer stability and comfort, reducing flat‑tire worries. The Shimano 7‑speed drivetrain and mechanical disc brakes give you control on any surface.
V. City Accessories, Ready to Ride
The bike comes with front and rear mudguards, front and rear lights (including a brake light), a cushioned rear rack, and a 6 km/h walk‑assist mode for inclines. The gift box also includes an inner tube, brake pads, a multi‑tool, and other accessories – ready to ride straight out of the box.
