SUNNIGOO C91 1000W Electric Bike for Adults — High-Speed Fat-Tire E-Bike, 150 kg Load

The SUNNIGOO C91 is a 1000W high-speed fat-tire electric bike built for adult riders who want more power, more load capacity and more terrain freedom than a standard 250W pedelec. With a 48V 1000W motor, a top speed of 55 km/h, a 150 kg max load and a removable battery up to 48V 20Ah, 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.

What is the SUNNIGOO C91?

The C91 is a high-power fat-tire electric bike 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.

How fast is the C91?

The C91 reaches a top speed of 55 km/h 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.

What range can I expect from the C91?

Range depends on the battery you choose. With the 48V 17.5Ah battery, expect roughly 50–70 km in mixed real-world riding. With the 48V 20Ah battery, expect 60–80 km under test conditions (75 kg rider, flat dry road, eco pedal assist). Heavier loads, hills, cold weather and high speeds reduce range.

Is the C91 legal on European roads?

The 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 private land, trails and roads where local law allows higher-powered e-bikes. 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.

What is the weight and max load of the C91?

The C91 weighs 32 kg net and 43 kg gross in the box. Its reinforced aluminum-alloy frame and double-shock rear suspension are rated for a 150 kg maximum load, 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.

How long does the C91 battery take to charge?

Using the included 48V smart charger, a full charge takes 4–8 hours 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.

What is included in the box and where can I get service?

Each C91 ships 90% pre-assembled in a 146 × 32 × 78 cm 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. For warranty claims, keep your order number and the original packaging.

Technical Specifications

Built for Power, Load and Rough Terrain

The C91’s 20×4.0 inch fat tires spread weight over a wide contact patch, giving it grip on gravel, wet tarmac and sand that standard city tires cannot match. The dual shock absorbers and front + rear disc brakes keep the ride controlled when the surface is uneven or the load is heavy. A USB charge port on the battery lets you keep a phone or GPS powered on longer rides.

Three Battery Options for Different Rides

Choose the battery that fits your mileage. The 15Ah battery is the lightest and most compact option for short daily loops. The 17.5Ah battery balances weight and range, while the 20Ah battery delivers the full 60–80 km quoted range. All batteries use the same key-locked mount and can be charged off the bike.

Frequently Asked Questions

Who is the C91 designed for?

The C91 is designed for experienced adult riders who want a powerful, high-load electric bike for private roads, trails and permitted areas. It is not a beginner or standard commuter pedelec.

Can I ride the C91 on public roads in the EU?

In most EU countries the C91 exceeds the 250W / 25 km/h pedelec limit. Public-road use may require registration, insurance and a helmet. Always check local regulations before riding on public roads.

How far can the C91 travel on one charge?

Expect 50–70 km with the 17.5Ah battery or 60–80 km with the 20Ah battery under ideal test conditions. Real-world range is lower with hills, heavy loads, cold weather or high speeds.

How long does the battery last before it needs replacing?

The lithium battery is rated for roughly 500–800 full charge cycles before noticeable capacity loss. With normal use this usually means several years of service.

Does the C91 come with a charger and tools?

Yes. The box includes a 48V smart charger, basic assembly tools, pedals and the user manual. The bike arrives about 90% assembled.

What warranty covers the C91?

SUNNIGOO provides a 2-year warranty on the frame, motor and battery against manufacturing defects, plus EU-based support for spare parts and service.

Een stabiele rit met zitje, elke dag opnieuw

De SUNNIGOO L3 is een elektrische scootmobiel met zitje, ontworpen voor volwassenen en senioren die stabiliteit belangrijker vinden dan snelheid. De twee motoren van elk 250W (samen 500W) nemen flauwe hellingen moeiteloos, terwijl drie versnellingen — 6, 12 en 18 km/u — het tempo laten meebewegen met de berijder en de weg.

45-60 km op één accu

De 36V 18Ah lithiumaccu brengt de L3 45-60 km ver op één nachtelijke laadbeurt van 5-8 uur — een volle week boodschappen, rondjes door het park en ritjes in de buurt zonder stekker.

Veiligheid die je ziet

De 10 inch anti-slip banden houden de L3 stevig op een nat fietspad, en het geïntegreerde LED-remlicht waarschuwt fietsers en automobilisten achter je nog voordat je vaart mindert. Als scootmobiel rijdt hij rustig en voorspelbaar — precies de veiligheid die het zwaarst weegt voor senioren en voor de families die hun vervoer kiezen.

Opgevouwen in de kofferbak, klaar voor de dag

Het zitkussen is afneembaar en het frame klapt in tot 420 × 580 × 760 mm — klein genoeg voor een autokoffer of een hoek in de berging. Het frame is geschikt tot 120 kg, met eenvoudige bediening en een comfortabel zitje waar je makkelijk op- en afstapt.

Een ochtend in Amsterdam

Stel je een 72-jarige gepensioneerde leraar voor wiens knieën niet meer willen samenwerken met een fiets. Zijn dochter zocht het uit, vergeleek scootmobielen en elektrische fietsen, en koos uiteindelijk voor een opvouwbare scootmobiel met zitje die overzichtelijk voelde in plaats van intimiderend.

Nu hebben de ochtenden weer ritme: via het fietspad naar de markt, met brede banden die ook na een regenbui stevig staan; en weer naar huis met de boodschappen. De middagen zijn voor het park, de eenden en de buren die blijven zeggen hoe makkelijk hij te hanteren is vergeleken met een standaard scootmobiel.

In zijn eigen woorden: beter dan wachten op de bus — en de route die hij elke dag rijdt, is het bewijs.

Technische specificaties

Zoek je een scootmobiel met zitje, een opvouwbare elektrische scootmobiel voor senioren, een stabiele scootmobiel voor een ouder, of een makkelijk te besturen gehandicaptenvoertuig? De L3 is precies rond die wensen ontworpen.
