DYU D3S Mini Folding Urban Commuting Electric Bicycle

The DYU D3S is a mini folding pedal-assist e-bike designed mainly for short-distance urban travel. It features a high-strength frame, a 250W motor, a 36V 10Ah lithium battery, 14-inch city tires, front and rear dual disc brakes and IP54 dust-proof & waterproof rating. The default maximum speed is 25km/h with a maximum climbing angle of 15°, a pedal-assist range of up to 50km and a charging time of 5-6H. Gross weight: 19.7kg; maximum payload: 120kg. Product dimensions: 1170×500×990mm; folded dimensions: 1170×200×720mm. Once folded, it becomes compact and small enough to fit in a car trunk, elevator or hallway corner, making it ideal for office workers' commutes, supermarket shopping and short rides while solving the parking and storage problem for urban residents.

【Lightweight Whole Bike, Effortless Moving & Handling】

The DYU D3S has a gross weight of only 19.7kg. Its lightweight body design lets a single person move it, lift it into an elevator or load it into a trunk. The frame structure is reinforced, supporting a maximum payload of 120kg to carry the rider plus backpacks and shopping items. The frame geometry is optimised for city riding, offering an upright, relaxed posture to prevent back and waist soreness during long rides. Balancing lightweight construction and structural strength, it is very friendly for urban users living in apartments without a private garage who need to move the bike frequently, laying a solid foundation for daily travel.

【Quick Folding, Flexible & Convenient Storage】

The DYU D3S features a simple folding mechanism that completes a full fold quickly without extra tools. Once folded, it measures 1170×200×720mm with a greatly reduced thickness, significantly lowering the footprint. On weekend road trips, fold it and place it directly in the car trunk to ride in the suburbs; at home, store it on the balcony or in a hallway corner, or bring it into the office to avoid outdoor parking theft concerns. The folding latch locks securely without play or wobble during riding, ensuring safety. Unfolding is simple and easy to understand, and novices can master the fold/unfold process in a short time. It perfectly suits small urban households, greatly easing storage pressure.

【14-Inch Tires, Comfortable Urban Vibration Filtering】

Fitted with 14-inch city-spec tires with a solid rubber compound suited to paved urban asphalt roads. The tires provide inherent cushioning, effectively filtering road bumps when passing over city speed bumps, manhole covers and small potholes. The tread pattern balances low rolling resistance on city roads and grip on wet surfaces — on rainy, damp asphalt, the tires stay well in contact with the ground to reduce slipping risk. The tire casing is wear-resistant for long service life on paved city roads and easy to replace later. Combined with the frame tuning, riding vibration is effectively reduced, easing fatigue in wrists and hips. Without complex external suspension, it delivers good urban riding comfort.

【Front & Rear Dual Disc Brakes, Reliable Commuting Braking】

The e-bike is equipped with front and rear dual disc brake systems with a linear brake feel. Light lever pressure brings smooth deceleration, while a firmer grip completes a stop; proper operation reduces the risk of wheel lock-up and skidding. In rainy urban environments, disc brakes are far less affected by mud and water than ordinary rim brakes, delivering more stable braking performance. At busy city intersections with mixed traffic, riders can precisely control speed and calmly handle unexpected road conditions. Combined with IP54 dust-proof & waterproofing, electrical components resist rain splashes during light rain rides, comprehensively safeguarding every urban commuting trip.

【250W Motor, Smooth Foot-Following Assistance】

The e-bike is fitted with a 250W drive motor with a default maximum speed of 25km/h and a maximum climbing angle of 15°. Power delivery is linear and gentle — quiet and smooth on flat city roads. On community slopes and gentle pedestrian-overpass ramps, it delivers stable traction to ease pedalling strain. The motor runs quietly without noise disturbance through residential areas. In assist mode, power follows pedalling output for a riding feel close to a regular bicycle, easy for beginners to handle. Multiple riding modes allow free switching — pure electric, assist and manual — to meet varied urban commuting needs.

Lightweight Mini Folding Urban Commute Pedal-Assist E-Bike

The DYU D3S mini folding electric bicycle integrates five core configurations: lightweight body, quick-fold storage, 14-inch city tires, front & rear dual disc brakes and a 250W assist motor. Compact and easy to store when folded, lightweight and easy to move, with IP54 dust-proof & waterproofing, it is ideal for urban office workers and apartment dwellers for short daily commutes.
