Product Description
Foldable Step‑Through Frame Fits Anywhere
The bike folds quickly at the frame, handle stem and pedals within seconds, easy to store under desks, inside closets or car trunks. The open step‑through frame eliminates awkward leg lifting, enabling effortless mounting and dismounting for daily trips.
Dual‑Side Torque Sensor Delivers Genuine Riding Feel
Built‑in dual torque sensor precisely detects your pedaling force and outputs matched power smoothly without abrupt jerky starts. Ensures steady low‑speed control amid city traffic and reliable climbing assistance, just like riding a conventional bike with constant tailwind support.
Large Lockable Removable Battery for 75‑100km Real Range
Equipped with a lockable 36V 20Ah (720Wh) 21700 lithium battery, detachable for indoor home or office charging. IPX5 waterproof protection plus 3A fast charging takes 8‑10 hours per full charge, effectively solving range anxiety for weekday commutes and weekend outings.
Dual Suspension & Puncture‑Proof Tires Boost Riding Ease
The 40mm front suspension fork plus 15mm rear suspension seatpost absorb bumps, potholes and cobblestone shocks on rough urban roads. The 20×2.5 inch puncture‑resistant air tires prevent flats and provide stable grip on wet pavement for smooth cruising.
Full Complete Factory Fittings Ready to Ride
Comes pre‑fitted with Shimano 7‑speed drivetrain, mechanical disc brakes, padded rear rack, full fenders and front & rear LED lights. Added practical 6km/h walk assist mode to help push the bike up slopes; a complimentary accessory gift box is included.
