The VIVI Gopina is a compact, 16″ fat-tire folding ebike designed for riders who want car-trunk portability, all-terrain versatility, and everyday commuting comfort in one small package. With 3.0″ wide tires, a 700W peak rear hub motor, a 48V 7.8Ah removable battery, and an integrated rear rack, it’s built for city streets, beach paths, light snow, and neighborhood errands—without demanding a lot of storage space at home.
Compared to full-size 26″ or 27.5″ ebikes, the Gopina leans into agility and convenience: mini wheels, a folding steel frame, and step-over or step-through options that stay approachable for riders from about 5’0″ to 6’2″.

Design & Frame: Mini Fat-Tire Folder with Step-Over & Step-Through Options
The VIVI Gopina’s frame design focuses on being small, sturdy, and easy to live with:
- High-carbon steel folding frame
Steel keeps costs down and adds robustness for day-to-day use. The mid-frame hinge and folding stem help shrink the bike for closets, car trunks, RV storage, or under-stair spaces. - Step-over and step-through variants
You can choose the frame style that fits your mobility and aesthetic preference. The step-through version makes mounting and dismounting much easier for shorter riders or those with limited hip mobility. - Mini geometry with fat tires
The 16″ wheels keep the overall length and wheelbase compact, while the 3.0″ width gives you more grip and comfort than a narrow city tire.
Overall, this isn’t trying to be a big, stretched-out cruiser. It’s intentionally compact, upright, and practical for dense urban environments, tight storage, and multi-modal commuting.

Motor & Power: 700W Peak Hub Motor with 50 Nm of Torque
At the heart of the Gopina is a 700W peak brushless rear hub motor rated at 50 Nm of torque. For a 16″ wheel, that torque translates into punchy takeoffs and confident support on hills.
On the road, that looks like:
- Class 2 behavior – Throttle and pedal assist up to about 21.7 mph, with a more efficient “regular” speed around 15.5 mph.
- Good low-speed control – The smaller wheel diameter means the motor doesn’t have to work as hard to get you moving, which is handy in stop-and-go city traffic.
- Predictable cadence-based assist – The 12-magnet cadence sensor measures crank rotation, not how hard you push. It’s very beginner-friendly: when you pedal, the bike helps; when you stop, power fades out.
Riders who mainly want a nimble city/errand bike, rather than a high-speed long-distance machine, will find this power profile more than adequate.
Battery, Charging & Realistic Range
The Gopina’s 48V 7.8Ah (374.4Wh) removable battery is mounted to keep the center of gravity low and centralized. VIVI’s own numbers:
- PAS range: about 34–50 miles
- Pure electric (throttle) range: about 22–25 miles
In real-world terms, your range will depend on your weight, terrain, wind, temperature, and how often you use higher PAS levels or throttle.
A reasonable planning range for most riders:
- 20–30 miles of mixed PAS riding (levels 2–3, rolling terrain, modest speeds)
- 25–35 miles for lighter riders on mostly flat routes who stay in ECO/MID modes
- 15–22 miles if you lean heavily on throttle-only riding at higher speeds
The included 54.6V 2A charger brings the battery from empty to full in about 4–6 hours, so topping off between rides is easy.
Ride Comfort & Handling
Despite its compact size, the Gopina is built to ride smoother than a typical small-wheeled folder:
- Coil-spring suspension fork (35 mm travel)
The lockable front suspension takes the edge off potholes, speed bumps, and curb drops. - 16″ x 3.0″ fat tires
The extra air volume and width soak up chatter, add grip on loose or wet surfaces, and tame broken city pavement better than narrow commuter tires. - Ergonomic touchpoints
Imitation leather grips and an ergonomic breathable saddle aim to reduce fatigue on longer rides.
Handling-wise:
- The short wheelbase makes it easy to weave through traffic and tight spaces.
- The fat tires slow steering just enough to keep the bike from feeling twitchy, especially at higher PAS levels.
If you’re coming from a rigid mini-folder or a non-suspension scooter, the ride comfort here will feel like a step up.
Brakes, Tires & Safety
Stopping and control are handled by:
- 160 mm mechanical disc brakes (front and rear) with aluminum calipers and semi-metallic pads
- Alloy levers with motor cut-off switches, so braking immediately cuts power to the motor
- 16″ x 3.0″ anti-puncture fat tires with integrated 3-blade alloy rims that add both stiffness and style
On the safety/compliance side, the Gopina is:
- SGS-tested and certified to UL 2849 (ebike system) and UL 2271 (battery), and
- Labeled GCC | CPSC 1512, aligning with modern ebike safety standards.
There’s also a 48V integrated LED headlight and rear reflector. Many riders will still add an extra blinking taillight or helmet-mounted light for serious nighttime commuting, but the stock setup gives you a solid baseline.
Folding & Storage: The Gopina’s Superpower
One of the Gopina’s biggest advantages over full-size fat-tire bikes is how small it gets when folded:
- Folding dimensions: roughly 83 × 59 cm (32.6″ × 23.2″) footprint
- Retractable folding stem plus compact wheelbase for a smaller package
- Integrated rack and fenders stay attached, so you don’t juggle extra pieces
This is ideal if:
- You want to store the bike in a car trunk or SUV without a rack.
- You live in a small apartment, dorm, or shared house where floor space is tight.
- You plan to combine riding with transit, and need a bike you can bring on a train or bus (depending on local rules).
There’s still 60 lb of mass to lift, so it’s not a featherweight, but as fat-tire folders go, it’s very space-efficient.
Everyday Utility & Use Cases
The Gopina is designed around real-world use, not just spec sheet appeal:
- Urban commuting – PAS 2–3 keeps you at a comfortable 15–18 mph while the fat tires and suspension fork handle rough pavement and occasional gravel.
- Errands and cargo – The rear rack (rated up to 100 lb) plus full-coverage fenders make it a practical grocery-getter or “second car” for neighborhood tasks.
- Beach and boardwalk riding – 3.0″ tires plus a 700W peak motor help in sand and soft surfaces where skinny tires struggle.
- Light snow and shoulder seasons – Fat tires give more confidence on slushy bike paths than narrow commuter tires, as long as you ride within conditions and your comfort level.
- RV / van life – Its compact folded footprint and integrated rack make it particularly attractive as an RV “runabout.”
If you’re replacing a lot of 2–8 mile car trips and want something that fits your life as much as your garage, this is the niche the Gopina targets.
Pros & Cons
Pros
- Compact 16″ x 3.0″ fat-tire platform that’s easy to store and maneuver
- 700W peak rear hub motor (50 Nm) provides strong assist and hill support for a mini ebike
- Removable 48V 7.8Ah battery with realistic 20–35 mile range for typical urban riders
- Folding frame and stem make it highly trunk- and apartment-friendly
- Step-over and step-through options, plus a wide 5’0″–6’2″ rider-height window
- Full equipment out of the box – integrated rear rack, full fenders, lights, kickstand
- UL 2849/2271 and CPSC 1512 compliance, plus IP54 rating for added peace of mind
Cons
- Mechanical disc brakes instead of hydraulic; they work, but need more frequent adjustment and lack hydraulic lever feel
- The 374Wh battery is modest compared to larger-pack touring bikes; regular long-distance riders may want more capacity or a spare battery
- At ~60 lb, it’s still a substantial lift for carrying up multiple flights of stairs
- Cadence-based PAS is more “on/off” than torque-sensor systems; riders wanting the most natural pedal feel may prefer a torque-sensor commuter
- 16″ wheels can feel a bit more reactive over sharp obstacles than larger-diameter 20–27.5″ wheels, so line choice matters on rougher terrain
Who the VIVI Gopina Is Best For
The Gopina is a strong match if:
- You need a folding, fat-tire ebike that fits in tight spaces (apartments, elevators, trunks, RV bays).
- You ride primarily in urban or suburban settings, with a mix of pavement, bike paths, and the occasional gravel or beach segment.
- You value comfort and stability—fat tires, front suspension, and an upright posture—more than maximum speed.
- You want one bike for commuting and errands, with a ready-to-go rack and fenders.
- You’re between about 5’0″ and 6’2″, and like the idea of a smaller wheel bike that still feels solid and confidence-inspiring.
Who Might Want a Different Bike
You might be happier with another model if:
- You routinely ride very long distances and want a battery closer to 600–960Wh.
- You strongly prefer hydraulic disc brakes for steeper, faster descents.
- You almost exclusively ride on smooth pavement and would rather have a lighter, larger-wheeled road/commuter ebike.
- You’re significantly taller than 6’2″, or need a very large frame for fit reasons.
- You prioritize extremely high top speeds or aggressive trail riding—this is more of an all-terrain city/utility bike than a hardcore mountain rig.
Final Thoughts: Is the VIVI Gopina Worth It?
If you’re looking for a compact, fat-tire folding ebike that can handle city commutes, beach paths, and light snow while still living comfortably in a small space, the VIVI Gopina makes a very strong case for itself.
You’re getting:
- A 700W peak hub motor with 50 Nm of torque in a 16″ wheel setup
- A 48V 7.8Ah removable battery that realistically covers most daily urban use cases
- 3.0″ fat tires, suspension fork, and ergonomic contact points for comfort on less-than-perfect roads
- A folding steel frame, retractable stem, and integrated rack/fenders that support real-world errands and storage
- Modern safety certifications (UL 2849/2271, CPSC 1512) and IP54 protection
It’s not a long-range touring machine or a big-wheeled cargo hauler—but that’s the point. For riders who want a space-efficient, go-anywhere mini fat-tire ebike that can replace a lot of short car trips and still be fun on weekends, the Gopina delivers what it promises.
