1. Power & Gradeability Tests
Performance: Our motors are tested to maintain consistent power output under heavy loads.
Incline Mastery: Each model is verified to conquer inclines, ensuring seamless navigation through underground garages and city overpasses.
2. Battery Endurance & Safety
Real-World Range: We conduct multi-environment range tests. Our high-capacity Lithium-ion batteries are proven to deliver km depending on the riding mode (Pure Electric vs. PAS).
Thermal Management: Batteries are tested for charging efficiency and heat dissipation to prevent overheating and ensure a long lifecycle.
3. All-Terrain & Shock Absorption
Surface Adaptation: whether from 10-inch puncture-resistant tires to 20-inch Chaoyang fat tires, we test grip and stability on wet asphalt, gravel, sand, and snow.
Suspension Rigidity: Our full-suspension and hydraulic systems undergo thousands of compression cycles to guarantee a "smooth-as-silk" ride on uneven urban roads.
4. Safety & Braking Precision
Stopping Power: We equip our vehicles with Dual Braking Systems (Hydraulic Disc or Electronic Brakes). Every batch is tested for immediate stopping distance, even at maximum speeds.
Visibility: Integrated LED lighting and signal systems are vibration-tested to ensure 360° visibility in low-light or high-impact conditions.
5. Structural Integrity & Material Quality
Load-Bearing: Our Aerospace-grade Aluminum Alloy frames and premium silicone pedals are tested for corrosion resistance and anti-slip durability.
Quality Control: With 99% self-developed components, we ensure unparalleled consistency and mechanical reliability across our entire lineup.
Fast Delivery: E-bikes ship from our warehouses in Germany and Italy; e-scooters ship from Germany, Poland and France. Expect your bike to arrive within 3-7 days.
Shipping & Tax: We offer free shipping on most orders. Prices include VAT for EU deliveries.
Official Warranty: Every SUNNIGOO product purchase is protected by an official warranty: 1 year on the frame, 6 months on motor, controller, display and charger, and 3 months on the battery.
Professional Support: Our technical team provides 24/7 online support to assist with assembly, maintenance, or troubleshooting.
Ready to Ride: Arrives in 85-90% SKD packing mode, ensuring the product is nearly ready for use right out of the box with minimal assembly required.
Sustainable Commuting: The SUNNIGOO product is designed to provide a high-performance alternative to fossil-fuel vehicles, helping riders significantly reduce their personal carbon footprint.
Efficient Energy Management: Our high-capacity lithium-ion battery utilizes optimized energy consumption technology to maximize battery life cycle and reduce electronic waste.
Durable Engineering: By using a lightweight aluminum alloy frame and professional-grade components like Shimano and Chaoyang, we create a durable product meant for years of use rather than frequent replacement.

El confort es la clave
La mayoría de las bicicletas eléctricas plegables de esta categoría ahorran costes prescindiendo de la suspensión. La SUNNIGO B4 no. Con suspensión total integrada en el cuadro de aleación de aluminio y neumáticos fat de 4,0 pulgadas que absorben los baches, esta e-bike urbana todoterreno te mantiene cómodo sobre adoquines, senderos junto al canal y pistas ligeras. Para quienes quieren una bicicleta eléctrica con suspensión sin el precio de una e-bike de montaña de doble suspensión, la B4 es el punto medio inteligente.
Una bici para dos mundos
La doble personalidad de la B4 es su mayor fuerza: es una e-bike de trayectos diarios que maneja la rutina — batería extraíble, pantalla LCD, portaequipajes para la compra — y una bicicleta eléctrica todoterreno para escapadas de fin de semana. Neumáticos anchos y frenos de disco hidráulicos te dan la confianza para pasar del asfalto a la grava sin perder el ritmo.
Resistente, plegable, habitable
Vivir en una ciudad europea significa espacio limitado. El cuadro plegable de la B4 se pliega rápido: esta e-bike de neumáticos fat tan completa vive feliz en un rincón del pasillo o en el maletero cuando no la usas — sin necesidad de garaje.
La SUNNIGO B4 es la bicicleta eléctrica con suspensión total para ciclistas que se niegan a elegir entre comodidad y capacidad. Con el soporte europeo de SUNNIGO y envío rápido en la UE, está lista para tu trayecto, tu fin de semana y todo lo demás.

About Your SUNNIGOO
Yes. SUNNIGOO e-bikes sold in the EU are engineered to comply with European e-bike regulations, including the CE EN15194 standard, with pedal-assist up to 25 km/h — legal on European roads and bike paths without registration or a licence. Check your model’s specifications for its exact motor rating.
Range varies by model — many of our e-bikes deliver up to 120 km on a single charge in eco mode, measured with a rider around 75 kg on flat terrain. Real-world range depends on your weight, terrain, assist level and weather. Check the specifications of your model for its exact range.
Yes — the battery is fully removable, so you can lock the frame outside and charge the battery indoors at home or at the office.
Very little. Keep the tyres inflated, the brake pads adjusted and the chain lubricated, and your e-bike will stay reliable for years. If anything needs attention, our support team is available 24/7.
