SUNNIGOO B5 – 20" Fat Tire Electric Bike | 600Wh Battery | Up to 50-80km Range | EU Standards Certified

The SUNNIGOO B5 is a 20-inch fat-tire electric bike built to move confidently through the city and beyond. With a powerful 600Wh battery, oversized 4.0" tires, and EU-compliant 25 km/h Pedelec performance, the B5 blends daily commuting comfort with genuine all-terrain capability — no license required to ride across the EU.

🔋 600Wh Battery, Up to 50-80km Combined Range
The removable 48V 12.5Ah (600Wh) lithium battery delivers 35–40 km in electric-only mode and 50–80 km in pedal-assist mode — up to 120 km combined on a single charge. Charge anywhere with the included 100–240V charger and EU-standard round plug, whether you're at home, the office, or on the road.

🛞 20"×4.0" Fat Tires for All-Terrain Confidence
Wide Chaoyang 20×4.0" fat tires soak up cobblestones, gravel, mud, and light snow with ease, giving the B5 the stability and traction of an off-road bike while staying nimble enough for tight city streets. The compact 20-inch wheel size also makes storage and maneuvering easier in apartments, elevators, or car trunks.

⚙️ Smooth, Reliable Power Delivery
A 600W rear motor paired with Shimano 7-speed gearing gives you smooth, EU-legal pedal assistance up to 25km/h — perfectly compliant with EU e-bike standards, so you can ride confidently without registration or a license across most of the EU.

🛑 Hydraulic Disc Brakes, Front & Rear
Stop with confidence in any weather. Front and rear hydraulic disc brakes deliver strong, consistent stopping power on wet cobblestones, gravel trails, or steep urban descents.

📟 LCD Display & Everyday-Ready Design
A built-in LCD screen keeps your speed and battery level in view at a glance. The lightweight aluminum alloy frame (33kg net weight) keeps the B5 practical for daily use, while the rear rack and front basket mounts (as shown) make it equally suited to grocery runs, deliveries, or weekend errands. Available in White and Military Green.

2. Do I need a license to ride the SUNNIGOO B5 in the EU?

🚲【Powerful Motor & Long Range】The electric scooter for adults with 1000W motor allows for speed up to 55KM/H. The max load is 150KG so it can meet the difference needs of  adults .

🚲【Battery & Tire 】High-capacity rechargeable and replaceable battery (48V/15Ah/20Ah) .20 inch, 4" fat tyres offer better traction and grip. The flexible nature of inflatable tires allows them to conform to the ground slightly, maximizing the contact area between the tire and the road. This enhanced grip improves stability, especially when cornering, braking, or riding on wet or slippery roads, lowering the risk of skidding.

🚲【Brake system】Front+ Rear Disc Brake .Disc brakes rely on calipers squeezing brake pads against a metal rotor, which generates far more stopping force than traditional rim brakes.
