With a \u003cstrong\u003e48V 1000W motor\u003c\/strong\u003e, a top speed of \u003cstrong\u003e55 km\/h\u003c\/strong\u003e, a \u003cstrong\u003e150 kg max load\u003c\/strong\u003e and a removable battery up to \u003cstrong\u003e48V 20Ah\u003c\/strong\u003e, the C91 is ready for private-road riding, trails and heavy cargo. It ships from our EU warehouse with delivery in 3–5 working days and is backed by a 2-year warranty.\u003c\/p\u003e\n\n\u003ch3\u003eWhat is the SUNNIGOO C91?\u003c\/h3\u003e\n\u003cp\u003eThe C91 is a \u003cstrong\u003ehigh-power fat-tire electric bike\u003c\/strong\u003e for experienced riders. Its 1000W motor and 20×4.0 inch tires give it the torque and grip to handle gravel paths, sand, wet roads and light off-road use, while the 7-speed drivetrain and five pedal-assist modes let you choose between relaxed cruising and full-throttle acceleration. It is not a standard EU pedelec, so public-road use may require local registration as a moped.\u003c\/p\u003e\n\n\u003ch3\u003eHow fast is the C91?\u003c\/h3\u003e\n\u003cp\u003eThe C91 reaches a top speed of \u003cstrong\u003e55 km\/h\u003c\/strong\u003e on private roads and permitted open ground. The motor responds quickly from a standstill and holds speed confidently even with a passenger or cargo on the rear rack. Always wear a helmet and respect local speed limits and road-use rules.\u003c\/p\u003e\n\n\u003ch3\u003eWhat range can I expect from the C91?\u003c\/h3\u003e\n\u003cp\u003eRange depends on the battery you choose. With the \u003cstrong\u003e48V 17.5Ah battery\u003c\/strong\u003e, expect roughly \u003cstrong\u003e50–70 km\u003c\/strong\u003e in mixed real-world riding. With the \u003cstrong\u003e48V 20Ah battery\u003c\/strong\u003e, expect \u003cstrong\u003e60–80 km\u003c\/strong\u003e under test conditions (75 kg rider, flat dry road, eco pedal assist). Heavier loads, hills, cold weather and high speeds reduce range.\u003c\/p\u003e\n\n\u003ch3\u003eIs the C91 legal on European roads?\u003c\/h3\u003e\n\u003cp\u003eThe C91 is rated at 1000W continuous power and 55 km\/h, which is above the 250W \/ 25 km\/h limit for EU pedelecs in most countries. It is intended for \u003cstrong\u003eprivate land, trails and roads where local law allows higher-powered e-bikes\u003c\/strong\u003e. In Germany and several other EU markets it may need to be registered and insured as a moped. Please check your national StVZO or equivalent rules before riding on public roads.\u003c\/p\u003e\n\n\u003ch3\u003eWhat is the weight and max load of the C91?\u003c\/h3\u003e\n\u003cp\u003eThe C91 weighs \u003cstrong\u003e32 kg\u003c\/strong\u003e net and \u003cstrong\u003e43 kg\u003c\/strong\u003e gross in the box. Its reinforced aluminum-alloy frame and double-shock rear suspension are rated for a \u003cstrong\u003e150 kg maximum load\u003c\/strong\u003e, enough for most adult riders plus a backpack or pannier load. The 170 × 70 × 105 cm frame size suits riders from approximately 165 cm to 195 cm.\u003c\/p\u003e\n\n\u003ch3\u003eHow long does the C91 battery take to charge?\u003c\/h3\u003e\n\u003cp\u003eUsing the included \u003cstrong\u003e48V smart charger\u003c\/strong\u003e, a full charge takes \u003cstrong\u003e4–8 hours\u003c\/strong\u003e depending on battery capacity and starting level. The battery is removable and locks with a key, so you can charge it indoors at home or in the office. A typical 500–800 full charge-cycle lifespan means years of regular use.\u003c\/p\u003e\n\n\u003ch3\u003eWhat is included in the box and where can I get service?\u003c\/h3\u003e\n\u003cp\u003eEach C91 ships 90% pre-assembled in a \u003cstrong\u003e146 × 32 × 78 cm\u003c\/strong\u003e carton. The box contains the bike, charger, basic tools, user manual and pedals. Spare parts, extra batteries and service support are available through SUNNIGOO’s EU support channel.
