Buying Vitilan online?
As with a car, ask where you can take your ride if it needs a repair.
Be cautious if a seller can’t give you a local workshop address, especially if they ship from overseas or dropship.
Check with the brand that the seller is authorised and ask who handles warranty repairs.

The Vitilan U3 Electric Bike is a compact, high-performance folding electric bike designed for riders who want power, versatility and portability. Featuring a 750W high-torque motor, 48V 13Ah lithium-ion battery and full suspension, it delivers a perfect balance of comfort, power and endurance.
Smooth Power Delivery The Vitilan U3 is equipped with a 750W brushless rear hub motor (peaking at over 1000W), delivering excellent torque for hill climbs and rapid acceleration. Multiple PAS (Pedal Assist System) levels and throttle control give riders full flexibility between effortless cruising and energetic pedalling. The motor is engineered for smooth, quiet operation while offering strong performance on city streets and trails alike.
Comfort & Control Engineered for comfort, the U3 features a dual-suspension system with a hydraulic front fork and rear spring shock absorber, effectively smoothing out bumps and uneven terrain. The 20” x 3.0” all-terrain fat tyres provide superior traction and stability across asphalt, gravel, sand or snow. Mechanical disc brakes on both wheels ensure confident, reliable stopping power in all weather conditions.
Smart Battery System Powered by a 48V 13Ah high-capacity lithium-ion battery, the Vitilan U3 can travel up to 70km on pedal assist or around 45km on throttle mode, depending on rider weight and terrain. The battery is removable and lockable for security, allowing convenient charging at home or work. A full charge takes approximately 5–6 hours.
Tech You Can Trust The U3 comes equipped with a multifunction LCD display showing PAS level, speed, trip distance, battery status and total mileage. Integrated LED headlights and a rear light improve safety and visibility for night rides. The system supports both pedal assist and throttle-only modes, giving you the flexibility to ride your way.
Built for Everyday Use The aluminium alloy folding frame is both strong and lightweight, supporting riders up to 150kg. Its foldable design allows for easy transport and storage, perfect for apartment living or car boot travel. With full suspension, fat tyres and a powerful motor, the U3 is designed for everyday commuting, weekend exploring and outdoor adventures on all terrain types.

Compact 750W drive with assist up to 20 MPH
A 750W rear hub motor gives the U3 lively, easy-going assistance without feeling jumpy. Assisted speed is listed up to 20 MPH and it is rated for climbs up to 15 degrees, helping you keep momentum on everyday routes. A thumb throttle is included for full-electric riding (where permitted).
48V 13Ah battery with range listed up to 35 miles
The 48V 13Ah battery is designed for practical day-to-day mileage, with range listed up to 35 miles depending on terrain and assist level. Charging time is noted as 6+ hours, so an evening charge can set you up for the next ride.
20 x 3.0 fat tyres, front suspension and mechanical discs
20inch x 3.0 fat tyres add stability and comfort, while front suspension reduces harshness over broken roads. Dual mechanical disc brakes provide consistent stopping control, and 7-speed Shimano gearing helps you manage different speeds and gradients. Max rider load is listed at 150KG and bike weight at 30KG. Folding design makes it easy to store and transport.

Yes. The U3 combines a step-through style frame with a foldable design, so it is easier to get on and off, easier to store at home and easier to take in a car than a larger non-folding e-bike.
Vitilan lists the U3 with a 750W rear hub motor with peak output up to 1056W, about 75Nm of torque, and a removable 48V 13Ah battery. The quoted range is around 48 to 73 km per charge, depending on rider weight, terrain, assist level and conditions.
The U3 is set up for comfort-focused commuting, with a suspension front fork, seatpost suspension and 20 x 3.0 inch tyres that keep the bike more compact and nimble than a bulkier fat-tyre model.
The U3 uses 160 mm mechanical disc brakes, Shimano 7-speed gearing and an LCD display that shows core ride data such as speed, battery level and assist mode.
The Vitilan U3 Foldable Electric Bike arrives mostly assembled. Final setup normally includes aligning and securing the handlebars, fitting the pedals and completing essential safety checks. Allow approximately 20–30 minutes, or select our professional assembly and PDI service.
The Vitilan U3 Foldable Electric Bike is not fully waterproof. Avoid prolonged exposure to heavy rain, and never submerge or pressure wash the bike or its electrical components. After riding in wet conditions, wipe the bike dry and store it in a dry, sheltered location.
