The Ideal Partner for City Commuting — U4 Folding Electric Bike
The U4 folding electric bike is designed for urban commuters, solving the "last mile" travel problem with its compact folded form, reliable range, and comprehensive safety configuration. Whether weaving through busy streets or combining with public transport, the U4 easily fits into your daily life, making every departure more efficient and convenient.
Design Highlights: Compact Folding, Easy to Carry The U4 features a precision folding mechanism that completes the folding of the frame and stem in three steps, with a folded size of only 81×69 cm, easily fitting into a car trunk or a corner at home. The overall weight is 26.5 kg. Although it has some weight, combined with the compact folded form, short-distance carrying or pushing is still effortless. The frame is made of sturdy material, and the folding lock is rigorously tested to ensure rigidity and stability while riding.
Performance Core: Strong Range, Ride as You Wish The top speed reaches 25 km/h, perfectly complying with EU electric bicycle standards, allowing legal use on the road without registration. Equipped with a 36V 10.4Ah detachable lithium battery, the official range is up to 88 km or more (actual range is affected by riding habits, road conditions, and other factors; comprehensive city range is about 40–60 km), sufficient for daily commuting and weekend leisure riding. The battery supports charging both on and off the bike, fully charging in 4–5 hours, convenient and flexible.
Safety Configuration: All-Around Protection, Peace of Mind Safety is the top priority of the U4 design. Front and rear dual mechanical disc brakes provide stable braking force, responding quickly whether in sunny weather or light rain. The LED high-brightness front light and multi-mode tail light (steady/flashing/off) significantly improve nighttime riding visibility, and handlebar reflectors further increase passive safety. The tires use 16×2.125-inch wide tires with strong grip, effectively filtering road vibrations. The bike has an IPX4 waterproof rating, fearless of rain splashes.
Smart Experience: Clear Display, Convenient Control The integrated LCD display provides real-time feedback on speed, mileage, battery level, and assist mode, with riding information clear at a glance. The display also supports unit switching, cruise control, brightness adjustment, and other settings, and has built-in fault code prompts for convenient daily maintenance.
Choose the U4, Start a New Efficient The U4 folding electric bike perfectly combines practicality and value for money, becoming the ideal choice for short city trips with solid range, reliable safety configuration, and convenient folding design. Whether you are an office worker, student, or leisure rider, the U4 accompanies you easily through the city, enjoying the freedom and fun of low-carbon travel.
