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.

Technical Specifications

In-Depth: Why the N9mate Outperforms

Performance. The N9mate's dual-motor architecture puts power down through both wheels, delivering traction and acceleration that single-motor scooters cannot match. Whether you select ECO for maximum range, SPORT for daily riding or RACE for full private-land performance (25 km/h), the N9mate keeps up with your pace — and climbs grades up to 38° without hesitation.

Range and charging. The 1152Wh battery pack is one of the largest in its class. Commuters can expect a full week of riding on a single charge, while weekend riders get the headroom for long mixed-terrain routes. A full recharge takes 6–8 hours overnight.

Ride quality. Front and rear double suspension works with 10-inch wide pneumatic tubeless tires to absorb potholes, cobblestones and off-road chatter. The wide deck and 200kg load capacity accommodate riders of all sizes with room to spare.

Security and smart features. Beyond a standard lock, the N9mate pairs with your phone via Bluetooth, unlocks with fingerprint password protection, and streams phone music and GPS audio through its onboard system. German-standard LED lighting front and rear provides full visibility in all conditions, and the IPX5 waterproof rating keeps you riding through the rain.

EU warehouse advantage. Every N9mate ships from our European warehouse with 3–7 day delivery, duty-free within the EU, backed by local after-sales support and spare-parts availability.

Rovoron R7 × SUNNIGOO — Dual-Motor All-Terrain Electric Scooter, Co-Developed with Minimotors

The Rovoron R7 × SUNNIGOO is a 60V dual-motor all-terrain electric scooter engineered for European riders who want off-road capability without sacrificing range or road composure. Co-developed with Minimotors, it pairs twin 900W brushless hub motors (1800W nominal, 2400W peak) with a 60V 28.6Ah lithium battery, 11-inch heavy-duty tubeless off-road tyres and a one-piece aviation-grade aluminium frame. Whether you are crossing gravel trails, climbing switchbacks or covering long private-land distances, the R7 delivers the power, range and control to match.

5 Key Advantages

• 2400W Peak Dual-Motor Power — Twin 900W MINIMOTORS brushless hub motors deliver 1800W nominal and 2400W peak output, pushing the R7 to 65km/h and holding momentum up 20°–35° inclines.
• 90km Range, Dual Charging Ports — The 60V 28.6Ah lithium pack delivers up to 90km per charge (approx. 65km at sustained high speed). Two charging ports let you run two chargers at once to cut recharge time.
• 11-inch Heavy-Duty Tubeless Off-Road Tyres — Tubeless pneumatics eliminate sudden inner-tube punctures on gravel and rock, paired with robust shock absorbers and an ultra-wide anti-slip silicone deck.

Technical Specifications

In-Depth: Why the R7 Leads Its Class

Off-road performance. The R7's dual-motor layout puts power through both 11-inch wheels, giving it the traction to climb 20°–35° slopes and the acceleration to hold 65km/h on private straightaways. Unlike single-motor scooters that struggle on loose surfaces, the R7 maintains composure on gravel, dirt and alpine paths.

Range and charging flexibility. A 60V 28.6Ah pack is large for this weight class, delivering up to 90km in mixed riding. For riders who want shorter downtime, the dual charging ports accept two chargers simultaneously, roughly halving the time needed to top up.

Ride quality and control. The 11-inch tubeless off-road tyres shrug off rocks that would puncture standard inner tubes. Robust shock absorbers and a wide silicone deck keep the rider planted through ruts and loose sections, reducing fatigue on long rides.

Visibility and smart features. At dusk the R7's 360° lighting system comes into its own: turn signals embedded in the frame, a high-mounted LED headlight and ambient pole lights make the rider visible from every angle. The MINIMOTORS smart LCD pairs with a Bluetooth app for gear selection, battery monitoring, lighting control and remote locking.

Built for European conditions. Every R7 ships from our EU warehouse with 3–7 day delivery, duty-free within the EU, backed by a 1-year official warranty and 24/7 after-sales support. The aviation-grade aluminium frame folds quickly for car boots, garages and public transport.

Frequently Asked Questions

Is the R7 road-legal in Europe?
The R7 is certified CE and RoHS. It is designed for private land and off-road use in most EU markets. Public-road legality varies by country and local regulations; check your national rules before riding on public roads.

How far can the R7 travel on one charge?
Up to 90km in economical mixed riding, or approximately 65km at sustained high speed. Real-world range depends on rider weight, terrain, temperature and riding mode.

Can I charge the R7 faster?
Yes. The battery has dual charging ports, so you can connect two compatible chargers at the same time to reduce total charging time.

How does the R7 compare to the S7?
The R7 uses a 60V platform with 1800W nominal dual motors and is ideal for all-terrain and long-distance private riding. The S7 is the flagship 84V hyperscooter with 5000W nominal output, DGT certification and longer range for riders who want maximum performance.

What surfaces can the R7 handle?
Gravel paths, dirt trails, alpine switchbacks, grass and uneven tarmac are all within its capability thanks to the 11-inch tubeless off-road tyres, robust suspension and dual-motor traction.

What after-sales support is included?
EU warehouse stock, 3–7 day delivery, tax-free shipping within the EU, 1-year official warranty and 24/7 support via service@sunnigoo.com.

Is the SUNNIGOO B5 legal on European roads?

The SUNNIGOO B5 is a 250W pedelec limited to 25 km/h, which classifies it as a standard electric bicycle under EU regulation (EN 15194). In most EU member states—including France, Spain, Germany and Italy—it can be ridden on public roads without registration, licence or insurance. Always check local rules, as helmet and lighting requirements vary by country.

How fast is the SUNNIGOO B5?

The B5 provides electric assistance up to a governed top speed of 25 km/h (15.5 mph), fully in line with EU pedelec regulations. The Shimano 7-speed drivetrain lets you pedal faster on flats or downhills, while the 250W rear motor delivers smooth, continuous support up to the legal limit.

How far can the B5 go on a single charge?

In pure electric mode, expect 35–40 km; in pedal-assist mode, range extends to 50–80 km—up to 120 km combined on a single charge. Figures are measured with a 75 kg rider on flat roads at 25°C without wind. Hills, heavy loads, low temperatures or high assistance levels will reduce real-world range.

What is the weight and max load of the B5?

The B5 weighs 33 kg net (40 kg gross with packaging), with a compact 20-inch wheel format that is easier to manoeuvre and store than a full-size 26-inch fat bike. The aluminum alloy frame supports a maximum rider weight of 120 kg, with the rear rack and front basket mounts adding practical cargo capacity for groceries and daily errands.

How long does it take to charge the battery?

The removable 48V 12.5Ah (600Wh) lithium-ion battery charges from empty to full in approximately 5–6 hours with the included EU charger (100–240V). Because the battery is removable, you can charge it at home, at the office or anywhere with a standard wall outlet—no special installation required.

What's in the box?

Your B5 arrives 85% pre-assembled (SKD, front wheel unassembled) with: the aluminum alloy frame, 48V 12.5Ah (600Wh) removable battery, EU charger, LCD display, front LED light, Chaoyang 20×4.0" fat tires, hydraulic disc brake system, Shimano 7-speed drivetrain, rear rack, assembly tools and a printed user manual. Final assembly takes about 15–20 minutes.

Where can I get spare parts?

Genuine spare parts for the B5—batteries, chargers, tires, brake pads and display units—are stocked in our EU warehouse and can be ordered directly through sunnigoo.com or the SUNNIGOO support team. Because every component is a standard size, servicing is straightforward at any local bike shop as well.

It is built for riders who want a comfortable commuter e-bike during the week and a capable off-road fat-tire bike on weekends, with a range of 50–80 km in pedal-assist mode and a top speed of 25 km/h.

How fast is the SUNNIGOO B4?

The B4 reaches a top speed of 25 km/h in pedal-assist mode, which matches the EU Pedelec limit for e-bikes across most European countries. The motor stops assisting above this speed, so you can ride on public roads without registration, insurance or a driving licence in most EU markets. Throttle-only mode is intended for private property or off-road use where local rules allow.

How far can the B4 go on a single charge?

Range depends on how you ride. In pure throttle mode the B4 covers about 35–40 km. In pedal-assist mode the range extends to 50–80 km. The 600Wh battery gives you enough range for several days of city commuting or a full day of trail riding. Range is measured with a 75 kg rider on flat, dry roads at 25 °C and is affected by terrain, rider weight, wind and assist level.

Is the SUNNIGOO B4 legal on European roads?

Yes. The B4 is configured as a standard EU Pedelec with a 250W motor and 25 km/h assist cut-off, so it complies with EN15194 rules in most EU countries. You can use bike lanes and regular roads where bicycles are allowed. Always check your local e-bike rules before riding, because some cities have additional helmet or equipment requirements.

What is the weight and max load of the B4?

The aluminium-alloy folding frame keeps the net weight to 30 kg, which is reasonable for a full-suspension fat-tire e-bike. The package weighs about 37 kg. The frame is rated for riders up to 120 kg, including any luggage on the rear rack.

How long does it take to charge?

Using the included 100–240V, 2A EU-round-plug charger, the 48V 12.5Ah battery charges from empty to full in approximately 6–7 hours. You can remove the battery to charge it indoors at home or at the office, which is useful if you park the bike outside.

What's in the box?

The B4 ships 85% pre-assembled. In the box you will find the folded bike frame with rear wheel attached, the front wheel, the removable battery, the charger, a basic tool set, the user manual and safety instructions. You will need to attach the front wheel, adjust the handlebars and tighten a few bolts before your first ride. Most riders are ready to go in 15–20 minutes.

Where can I get spare parts and service?

SUNNIGOO keeps brake pads, tyres, inner tubes, chargers and replacement batteries in stock at our EU warehouse. If you need help with assembly, maintenance or warranty, contact our EU-based support team through the contact page. The B4 is backed by a 2-year warranty and 30-day return policy for peace of mind.

Technical Specifications

In-Depth: Why the S7 Outperforms

Flagship power. The S7's 84V electrical architecture feeds dual 2500W motors that peak at 11500W. Acceleration is not merely quick; it is the kind of response that redefines what a stand-up scooter can deliver. On private land the S7 reaches 100km/h, while the road-legal mode limits output to 25km/h for compliant riding where local regulations allow.

Endurance and battery safety. A 84V 37.1Ah Samsung pack is one of the largest in the hyperscooter category, delivering up to 140km of range. The integrated Smart BMS monitors cell temperature, current and voltage, protecting against over-heating, short-circuits and over-charging across a wide temperature range.

Braking and suspension control. NUTT 4-piston hydraulic disc brakes front and rear provide the stopping force needed for triple-digit speeds. The adjustable interchangeable cartridge suspension can be set to Soft, Medium or Hard to match rider weight, terrain and riding style, while ~190mm ground clearance clears obstacles that catch lower scooters.

Smart ride integration. The EY4 smart display pairs with the Minimotors APP for smartphone diagnostics, custom speed tuning and performance tracking. Dual mechanical horns, full LED lighting with turn signals and ambient side lights keep the rider visible and audible in traffic.

EU compliance and logistics. DGT certification (BOE-A-2022-987) gives the S7 a clear path to Spanish road registration and supports authorised use across most EU member states. Ships from our EU warehouse with 3–7 day delivery, duty-free within the EU, backed by a 1-year official warranty and 24/7 after-sales support.
