The VIVI F26FUL is a high-step, 26″ x 4.0″ fat tire electric bike built for riders who want one machine for city streets, gravel paths, and casual off-road exploring. With a 1000W peak hub motor and a 48V 12.8Ah battery, it’s designed as a long-range, all-terrain option rather than a lightweight city commuter.
It’s best suited for taller riders (roughly 5’5″–6’6″) who are comfortable with a traditional high-step frame and value stability and power over minimal weight.

Ride Feel: Stable and Confident on Mixed Terrain
On the road and trail, the VIVI F26FUL feels like a small SUV on two wheels:
- 26″ x 4.0″ fat tires add a big contact patch and extra air volume
- The 80 mm suspension fork helps soften potholes, curb cuts, and trail chatter
- The high-step aluminum frame keeps things solid at 20–25 mph
It’s not a razor-sharp city racer. Instead, it feels calm and planted:
- Comfortable on cracked city asphalt
- Happy on gravel paths, canal trails, and light off-road
- More forgiving than slim tires on sand, snow, or wet grass
If you care more about feeling stable on rough or loose surfaces than slicing through tight traffic, this ride feel will make sense.
Motor, Battery & Real-World Range
The F26FUL’s 1000W peak hub motor with 75 Nm of torque is the main differentiator versus many entry-level fat tire ebikes.
On paper, the battery and range story looks like this:
- 48V 12.8Ah (614Wh) removable battery
- Spec table: max range up to 50 miles / 80 km
- PAS range: 34–50 miles (55–80 km)
- Throttle (ebike) range: 28–34 miles (45–55 km)
Elsewhere on the product page you may see “up to 60 miles of riding range” mentioned in the marketing copy. Since the detailed performance table lists 50 miles max, this review uses 50 miles as the official reference point.
In real-world mixed riding (some hills, some throttle, varying PAS levels), a reasonable expectation for most riders is:
- Around 25–40 miles per charge
The included 54.6V 2A smart charger typically takes about 4–6 hours from low to full, so overnight or workday charging is easy to plan around.
👉 Check the F26FUL’s motor and range details on the brand page before you decide.
Comfort & Fit (Best for 5’5″–6’6″)
The F26FUL is a high-step bike built for taller riders. Key fit points:
- Recommended rider height: about 5’5″–6’6″
- Standover height: ~30.3″ (77 cm)
- Max load: 330 lb (rider + cargo)
Comfort-wise, you get:
- Upright riding position that’s easier on wrists and lower back
- Adjustable seatpost with quick-release clamp
- Ergonomic imitation leather grips
- A breathable sport saddle
If you’re shorter than roughly 5’5″, the standover height and top tube will feel tall; a step-through model will likely feel safer and more confidence-inspiring.
Utility & Everyday Practicality
Even though it looks like a trail bike, the F26FUL is set up for everyday use:
- Full-coverage front and rear fenders
- Sturdy side kickstand
- Optional rear rack for panniers, trunk bag, or a small basket
- 330 lb total payload capacity
That’s enough for commuting gear, grocery trips, and light bikepacking, as long as you stay within the rack’s and overall load limits. For many riders, this can realistically replace a lot of short car trips.
Safety, Brakes & Weather Protection
The F26FUL checks several important boxes for safety and durability:
- Brakes: 160 mm double mechanical disc brakes with motor cut-off levers
- Lighting: 48V integrated LED headlight and rear reflector (many riders will add an active rear light)
- Horn: Integrated electric horn for city and path riding
- Weather: IP54 rating (resistant to dust ingress and splashing water)
- Electrical safety: SGS-tested system certified to UL 2849 (complete ebike system) and UL 2271 (battery), plus GCC and CPSC 1512 compliance
For buyers concerned about battery safety and charging at home or in apartments, those UL certifications are a meaningful plus.
Drivetrain, Handling & Control
The drivetrain and control setup are straightforward and familiar:
- Shimano 7-speed drivetrain (RD-TZ500 derailleur, SL-TX50 shifter, 14–28T freewheel, 42T chainring)
- 5 levels of pedal assist using a 12-magnet cadence sensor
- Half-twist plus thumb throttle for pure-electric riding
- Walk-assist mode for pushing up ramps or small hills
- Cruise control for holding a steady speed on longer, flatter stretches
The combination of 7 gears, a strong hub motor, and PAS levels means you can:
- Spin comfortably on flat ground at 15–20 mph
- Drop into lower gears for hills and start-ups
- Choose how much effort you want to put in on any given ride
Handling is stable and predictable, emphasizing confidence over ultra-quick steering—exactly what many fat tire buyers want.
Pros & Cons
Pros
- 1000W peak motor with 75 Nm torque for solid hill performance
- 48V 12.8Ah (614Wh) battery with realistic 25–40 mile mixed range
- 26″ x 4.0″ fat tires and suspension fork for comfort and stability off pavement
- High load rating (330 lb) suited to taller riders and light cargo
- Shimano 7-speed drivetrain with 5-level PAS and throttle for flexible riding
- Full fenders and integrated headlight included
- IP54 rating plus UL 2849 / UL 2271 certified electrical system
Cons
- High-step frame and ~30″ standover height are not beginner-friendly for shorter riders
- Around 62 lb with battery makes it heavy to carry up stairs or onto racks
- Mechanical (not hydraulic) disc brakes—functional but not premium
- Rear lighting is reflector-only; most riders will want an active rear light
- Rear rack is an extra purchase rather than standard
- No USB charging ports for phones or accessories
Who the VIVI F26FUL Is Best For
The F26FUL is a strong fit if:
- You’re within the 5’5″–6’6″ height range and comfortable with a high-step frame
- You want one ebike for city streets, gravel paths, and light off-road
- You value torque and range more than having the lightest possible bike
- You’re looking for a budget-friendly fat tire ebike with UL-certified electronics
- Your typical rides are 10–30 miles, and you’re fine charging every 1–3 rides
Who Should Probably Skip It
You may want to look at other models if:
- You’re shorter than about 5’5″ or strongly prefer a step-through frame
- You need to carry your ebike up stairs on a regular basis
- You want a very nimble, lightweight city bike with narrow tires
- You routinely ride 40–60+ miles at high speeds without charging
- You specifically want hydraulic brakes, torque sensors, or fully integrated rear lighting
In those cases, a step-through fat tire bike or a lighter commuter model will likely be a better match.
Final Verdict: Is the VIVI F26FUL Worth It?
If you’re a taller rider who wants a single fat-tire ebike for commuting, dirt paths, and casual off-road—and you don’t mind a heavier high-step frame—the VIVI F26FUL is easy to recommend.
You’re getting:
- A torquey 1000W peak motor
- A 48V 12.8Ah battery with solid real-world range
- 26″ x 4.0″ fat tires and a suspension fork for comfort
- UL-certified electronics and IP54 protection
- Practical touches like fenders, headlight, and walk-assist
It’s not built to be ultra-light or ultra-fancy, but as a long-range, all-terrain workhorse for taller riders, it hits a very appealing balance of power, capability, and price.
