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.
La SUNNIGOO B4 es una bicicleta eléctrica plegable de suspensión total con neumáticos fat bike de 20×4.0", un motor legal en la UE de 250W y una batería de litio extraíble de 48V 12.5Ah (600Wh). Está pensada para quienes quieren una e-bike cómoda para ir a trabajar entre semana y una fat bike todoterreno capaz los fines de semana, con una autonomía de 50–80 km en modo asistido por pedaleo y una velocidad máxima de 25 km/h.
¿A qué velocidad circula la SUNNIGOO B4?
La B4 alcanza una velocidad máxima de 25 km/h en modo asistido por pedaleo, el límite europeo para las e-bikes Pedelec en la mayoría de países de la UE. El motor deja de asistir por encima de esa velocidad, por lo que puedes circular por vías públicas sin matrícula, seguro ni carnet de conducir en la mayoría de mercados europeos. El modo solo con acelerador está pensado para terrenos privados o uso todoterreno donde la normativa local lo permita.
¿Qué autonomía tiene la B4 con una sola carga?
La autonomía depende de tu forma de conducir. Con el acelerador puro, la B4 recorre unos 35–40 km. En modo asistido por pedaleo, la autonomía se amplía hasta los 50–80 km. La batería de 600Wh ofrece energía suficiente para varios días de trayectos urbanos o una jornada completa por caminos. La autonomía se mide con un conductor de 75 kg sobre asfalto llano y seco a 25 °C, y se ve afectada por el terreno, el peso, el viento y el nivel de asistencia.
¿Es legal la SUNNIGOO B4 en las carreteras europeas?
Sí. La B4 está configurada como un Pedelec europeo estándar, con motor de 250W y corte de asistencia a 25 km/h, por lo que cumple la normativa EN15194 en la mayoría de países de la UE. Puedes usar carriles bici y vías normales donde esté permitido circular en bicicleta. Consulta siempre la normativa local de e-bikes antes de salir, porque algunas ciudades exigen casco o equipamiento adicional.
¿Cuál es el peso y la carga máxima de la B4?
El cuadro plegable de aleación de aluminio mantiene el peso neto en 30 kg, un valor razonable para una e-bike fat bike de suspensión total. El paquete pesa unos 37 kg. El cuadro está homologado para conductores de hasta 120 kg, incluyendo cualquier equipaje del portaequipajes trasero.
¿Cuánto tarda en cargarse?
Con el cargador incluido de 100–240V, 2A y enchufe europeo, la batería de 48V 12.5Ah se carga de vacía a llena en aproximadamente 6–7 horas. Puedes extraer la batería para cargarla en casa o en la oficina, algo muy práctico si aparcas la bici en la calle.
¿Qué incluye la caja?
La B4 se envía premontada al 85%. En la caja encontrarás el cuadro plegado con la rueda trasera montada, la rueda delantera, la batería extraíble, el cargador, un juego de herramientas básico, el manual de usuario y las instrucciones de seguridad. Antes del primer uso tendrás que colocar la rueda delantera, ajustar el manillar y apretar algunos tornillos. La mayoría de usuarios están listos para rodar en 15–20 minutos.
¿Dónde puedo conseguir repuestos y servicio técnico?
SUNNIGOO mantiene en stock pastillas de freno, neumáticos, cámaras, cargadores y baterías de sustitución en nuestro almacén de la UE. Si necesitas ayuda con el montaje, el mantenimiento o la garantía, contacta con nuestro equipo de soporte europeo a través de la página de contacto. La B4 incluye una garantía de 2 años y una política de devolución de 30 días para tu tranquilidad.

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.
