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.

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 homologated road 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 (B1146, BOE-A-2022-987) gives the S7 a clear path to Spanish road registration. 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.

SUNNIGOO Brake Pad (Brake Lining) — for N3LMAX / N3MAX / X7 / X7PRO / X10 Electric Scooters

This genuine SUNNIGOO brake pad (brake lining) is the direct replacement wear part for the disc brake systems fitted to five SUNNIGOO electric scooter models: N3LMAX, N3MAX, X7, X7PRO and X10. Brake pads are a consumable safety component — inspect them every 500 km and replace them when the friction material wears thin, so your scooter keeps full stopping power on wet city streets and steep descents alike.

Note: This brake pad (brake lining) set consists of a pair—i.e., 2 pads in total.

Compatible Models

This brake pad fits the following SUNNIGOO electric scooters (all shipped from our EU warehouse · 3-5 working days):

• SUNNIGOO N3LMAX (800W off-road scooter with seat)
• SUNNIGOO N3MAX (500W foldable scooter with seat)
• SUNNIGOO X7 (dual-motor scooter, 150 kg load)
• SUNNIGOO X7PRO (dual-motor off-road scooter)
• SUNNIGOO X10 (dual-motor off-road flagship)

Why Replace with Genuine SUNNIGOO Brake Pads?

• Consistent stopping power — friction compound matched to the original SUNNIGOO disc brake system for predictable, progressive braking.
• Low noise, low disc wear — the lining compound is formulated to protect the brake disc while keeping braking quiet.
• Easy installation — a standard caliper fitment; a local bike or scooter shop can replace a pair in about 15 minutes, or you can do it yourself with basic tools.
• Stocked in the EU — shipped from our EU warehouse in 3-5 working days, so your downtime stays short.

When Should You Replace Your Brake Pads?

Replace the brake pad when: braking feels weaker or spongy, you hear a metallic scraping sound under braking, the friction material is visibly below 2 mm, or the brake lever travel increases noticeably. Riding with worn pads damages the brake disc and significantly extends stopping distance — on a 25 kg scooter reaching 45-65 km/h, that margin matters.

Disclaimer: The accessories sold by this store are exclusively compatible with Sunnigoo branded scooters (identifiable by the marked batch number located beneath the footrest or on its side panel). Use with non-certified models may pose safety hazards and will automatically void the original manufacturer warranty. Always verify batch number compatibility before purchase.

The SUNNIGOO 48V 21Ah lithium battery pack is the original replacement pack for the X7 and X7PRO electric scooters: 1,008 Wh of usable energy in a 13S8P configuration, rated for 50 A continuous discharge so both 1,800 W hub motors can pull full current on a climb without the voltage sag that makes a tired pack feel slow. If your scooter now cuts out earlier than it used to, or the last bar disappears on a route it used to finish comfortably, the pack — not the motor — is almost always the part that has aged.

Technical Specifications

Which scooters does this pack fit?

This pack is built for the two 48 V, 21 Ah models on the same frame platform:

• SUNNIGOO X7 — dual-motor all-rounder, 3,600 W combined, 45–60 km per charge.
• SUNNIGOO X7PRO — off-road flagship with 11-inch pneumatic tires and uprated suspension, same 48 V 21 Ah pack, 45–60 km per charge.

Both models reach their full rated range on this pack, measured with a 75 kg rider on flat terrain, no wind, at 25 °C. Expect 10–20 % less in cold weather and 15–25 % less on sustained off-road climbs, where the dual motors draw current continuously.

What does not fit

Voltage and pack format differ across the range, and a mismatched pack will not seat in the battery bay — or worse, will not be protected by the scooter's controller. In particular:

• X10 — 60 V system with a 38 Ah pack. Higher voltage, different enclosure; do not substitute.
• N8 (48 V 13 Ah) and N9 (48 V 18 Ah) — same nominal voltage but a smaller, differently shaped pack with its own mounting points.
• N5, N6, N7PRO, N3MAX, N3LMAX, X11 — different pack formats and battery bays; this 21 Ah pack will not seat correctly, and the controller will not recognise its state of charge.

Not sure which pack your unit takes? Send the batch number stamped under the footrest and the battery model number printed on the pack label to service@sunnigoo.com and we will confirm before you order.

Signs the pack is reaching the end of its life

A lithium pack does not fail overnight. These are the usual warning signs, roughly in the order they appear:

1. Range drops by more than a fifth on a route you ride regularly — the clearest single indicator.
2. The last bar falls fast. A healthy pack holds its final segment; an aged one collapses from two bars to zero in a kilometre.
3. Noticeable power loss on climbs. Voltage sag under load trips the low-voltage cutoff before the pack is actually empty.
4. Charging finishes much sooner than the usual 6–8 hours — capacity is gone, not charging speed improved.
5. The pack feels warm or swells after a normal ride. Stop using it and contact us; this is a safety issue, not a performance one.

Fitting and first charge

Replacement takes about fifteen minutes with the hex keys in the box: power the scooter down, remove the deck panel, disconnect the main connector (never pull by the cable), lift the old pack out, seat the new one on its rails and reconnect until the latch clicks. Charge the new pack fully before the first ride so the battery management system can calibrate its top-of-charge reference. Keep the pack between 20 % and 80 % for long storage, and store it indoors above 5 °C over winter — a pack left flat and freezing for months loses capacity permanently.

Warranty and shipping

Battery packs carry a 12-month warranty against manufacturing defects, in line with the coverage on the scooter itself. Packs ship from our EU warehouse in 3-5 working days, with no customs paperwork or import duties for EU customers. Batteries travel as dangerous goods, so every pack is shipped in its original UN-certified carton — please keep the packaging if you may need to return it.

The SUNNIGOO Controller is the genuine replacement control unit for the N3MAX and N3LMAX electric scooters. It manages power delivery from the 48V battery to the 800W rated brushless motor, so throttle response, acceleration and braking cut-off stay exactly as SUNNIGOO engineered them.

Compatible Models

This controller is designed for:

• SUNNIGOO N3MAX — 800W foldable e-scooter with removable seat, 48V 13Ah, 35–45 km
• SUNNIGOO N3LMAX — 800W long-range off-road e-scooter, 48V 15Ah, 40–50 km

Old vs New Version

The main image shows the old and new SUNNIGOO N3MAX/N3LMAX controllers. Both versions are fully interchangeable and functionally identical; they differ only in appearance — the old version is slightly larger, the new version is more compact. Either version plugs straight into the N3MAX/N3LMAX wiring harness, no rewiring required.

Why Choose a Genuine SUNNIGOO Controller?

The controller is the brain of your scooter: it reads the throttle, drives the motor and coordinates the brake cut-off. A non-genuine unit can cause jerky acceleration, error codes or premature motor wear. This original part keeps precise control over speed and acceleration, a smoother and more efficient ride, and full compatibility with the safety logic of your scooter.

Disclaimer: The accessories sold by this store are exclusively compatible with Sunnigoo branded scooters (identifiable by the marked batch number located beneath the footrest or on its side panel). Use with non-certified models may pose safety hazards and will automatically void the original manufacturer's warranty. Always verify batch number compatibility before purchase.

Built to Last, Backed to Match

Every component is chosen for real-world abuse: Chaoyang tires for traction, hydraulic discs for wet-road safety, and a corrosion-resistant aluminum frame for years of service.

Frequently Asked Questions about the SUNNIGOO B3

Is the SUNNIGOO B3 legal on European roads?

The SUNNIGOO B3 is a 250W pedelec limited to 25 km/h, which classifies it as a standard electric bicycle under EU regulation (EN 15194 / Directive 2002/24/EC). 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 regulations, as helmet and lighting rules vary by country.

How fast is the SUNNIGOO B3?

The B3 provides electric assistance up to a governed top speed of 25 km/h (15.5 mph), fully in line with EU e-bike regulations. The Shimano 7-speed drivetrain lets you pedal faster on flats or downhills, while the high-torque 250W motor delivers smooth, continuous support up to the legal limit.

How far can the B3 go on a single charge?

In pure electric mode, expect 35–40 km; in pedal-assist mode, range extends to 50–80 km depending on assistance level, terrain and rider weight. Figures are measured with a 75 kg rider on flat roads at 25°C without wind. Hills, heavy loads or cold weather will reduce real-world range.

What is the weight and max load of the B3?

The B3 weighs 29.2 kg net (35.7 kg gross with packaging), and the foldable aluminum frame collapses in seconds to fit a car boot or hallway closet. The frame supports a maximum rider weight of 120 kg, with extra room for bags and groceries on daily commutes.

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, 2A). 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 B3 arrives 85% pre-assembled (SKD, front wheel unassembled) with: the folding aluminum frame, 48V 12.5Ah removable battery, EU charger, LCD display, front LED light, Chaoyang 20×4.0" fat tires, hydraulic disc brake system, Shimano 7-speed drivetrain, 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 B3—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.

• SUNNIGOO C91 (1000W, 48V 20Ah fat-tire e-bike) — high-speed flagship fat-tire e-bike.

The SUNNIGOO B4 is a full-suspension folding electric bike with 20×4.0" fat tires, a 250W EU-legal motor and a removable 48V 12.5Ah (600Wh) lithium battery. 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.
