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.

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.

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.

Le confort avant tout
La plupart des vélos électriques pliants de cette catégorie économisent sur la suspension. Pas le SUNNIGO B4. Avec sa suspension intégrale intégrée au cadre en alliage d'aluminium et ses pneus fat de 4,0 pouces qui absorbent les bosses, cet e-bike tout-terrain urbain vous garde à l'aise sur pavés, chemins de halage et sentiers légers. Pour ceux qui veulent un vélo électrique avec suspension sans le prix d'un VTT électrique tout suspendu, le B4 est le juste milieu intelligent.
Un vélo pour deux mondes
La double personnalité du B4 est sa plus grande force : c'est un e-bike de trajets quotidiens qui gère le quotidien — batterie amovible, écran LCD, porte-bagages pour les courses — et une biciclette électrique tout-terrain pour les évasions du week-end. Pneus larges et freins à disque hydrauliques vous donnent la confiance pour passer de l'asphalte au gravier sans transition.
Durable, pliable, habitable
Vivre dans une ville européenne signifie que l'espace est limité. Le cadre pliable du B4 se replie rapidement : ce vélo électrique fat bien équipé se glisse dans un angle de couloir ou un coffre quand il ne sert pas — garage non requis.
Le SUNNIGO B4 est le vélo électrique à suspension intégrale pour les cyclistes qui refusent de choisir entre confort et capacités. Avec le support européen SUNNIGO et une livraison rapide en UE, il est prêt pour vos trajets, vos week-ends et tout le reste.

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.
