The VIVI ACE07 is positioned as their “do-almost-everything” step-through fat tire e-bike: long range, all-terrain capable, but still very much a daily commuter with practical touches like an integrated rear rack and UL-certified electronics.

Ride Feel: Long-Range, Stable, and Confident
On the road, the ACE07 is built to feel planted and predictable. The combination of:
- 26″ x 4.0″ fat tires
- A step-through aluminum frame
- A front suspension fork with 100 mm of travel
gives it a “SUV-like” ride—more forgiving over potholes, curbs, and gravel than a typical commuter with 1.75″ tires.
The bike ships as a Class 2 setup: regular speed is about 20 mph, with a max of 25 mph when fully unlocked. That feels like a good match for this platform: quick enough to keep pace with urban traffic on side streets, but not so fast that it feels sketchy on loose surfaces.
You can ride it:
- As a comfortable commuter on pavement
- As an all-terrain cruiser for gravel paths, parks, and light off-road
- As a weekend explorer for mixed routes that combine city, paths, and dirt
The step-through frame makes starts and stops less awkward, especially if you’re shorter, riding in regular clothes, or dealing with limited mobility.

Motor, Battery & Real-World Range
The ACE07’s core performance story is simple: high peak power plus a big battery.
- Motor: 1475W peak brushless hub motor, 90 Nm torque
- Battery: 48V 15Ah (720Wh) semi-integrated battery, removable for charging or storage
On paper, VIVI lists:
- Max range: 50–60 miles total
- PAS range: 34–60 miles (55–95 km)
- Throttle (ebike) range: 28–34 miles (45–55 km)
Realistically, most riders will see something like:
- 25–40 miles with mixed PAS and throttle, moderate hills, and typical rider weight
- 40–55+ miles if you stay in lower PAS levels, keep speeds around 15–18 mph, and pedal consistently
The 54.6V 3A smart charger fills the battery in about 4–6 hours from low to full, which is reasonable given the 720Wh capacity.
This combo makes the ACE07 particularly attractive if:
- You have a longer commute (10–15 miles each way)
- You want to string together a full Saturday of errands and exploring
- You’d rather charge every 2–3 days instead of after every ride
Comfort & Fit (5’3″–6’5″)
VIVI lists the ACE07’s recommended rider height as 160–200 cm (about 5’3″–6’5″) with a max load of 330 lb (rider + cargo).
Comfort features include:
- Step-through frame: Lower standover makes mounting and dismounting easier, especially at lights.
- Adjustable seatpost & upright cockpit: 30.4 x 300 mm seatpost and swept bar help dial in a relaxed position.
- 100 mm suspension fork: Coil spring fork with lockout and adjustment helps tame bumps and curb cuts.
- Fat tires: 26″ x 4.0″ anti-puncture tires add a big cushion of air volume.
- Ergonomic touchpoints: Imitation leather ergonomic grips and a breathable sport saddle.
VIVI also publishes full geometry on the ACE07 spec sheet (total length, handlebar height range, seat-height range), but the key takeaway is simple: if you’re between about 5’3″ and 6’5″, you should be able to dial in a comfortable upright fit with room to adjust.
Taken together, those choices make the ACE07 well-suited for:
- Daily commutes over mixed pavement quality
- Riders with knee/hip sensitivity who benefit from an upright position
- Longer weekend rides where comfort matters more than raw speed
Utility: Racks, Fenders & Everyday Use
The ACE07 isn’t just “fun fat tires.” It’s set up as a practical utility bike out of the box.
You get:
- Integrated rear rack: Included rack rated for about 55 lb (25 kg), suitable for panniers or a trunk bag.
- Full-coverage fenders: Front and rear fenders to help manage spray on wet roads.
- Kickstand: Heavy-duty side-mounted aluminum kickstand for stable parking.
The frame is rated for 330 lb total load, which covers most adult riders plus gear, a loaded rack, and maybe a small child seat within the rack’s weight limit.
If you choose the “with rear basket” variant, it becomes even more legit as a car-replacement option for errands and grocery runs.
Safety, Brakes & Certification
On the safety front, the ACE07 checks several boxes that matter in 2025:
- UL Certification: SGS-tested and certified to UL 2849 (e-bike system) and UL 2271 (battery).
- Disc brakes with 180 mm rotors: The spec sheet confirms disc brakes with 180 mm rotors; language around “mechanical vs hydraulic” is a bit muddled, but the key point is that you’re getting disc braking with decent rotor size.
- Motor cut-off brake levers: Cutting power when you brake helps control on descents and in emergency stops.
- IP54 rating: Resistant to dust ingress and splashing water, useful for real-world commutes that occasionally include rain.
Lighting:
- 48V integrated LED headlight up front
- Rear reflector (you can easily add an active tail light for extra visibility)
From an electrical safety and braking standpoint, the ACE07 is more reassuring than off-brand bikes with no published certifications.
Drivetrain, Handling & Control
The ACE07 uses a Shimano 7-speed drivetrain:
- Shimano RD-TY300 7-speed rear derailleur
- Shimano SL-TX50 7-speed thumb shifter
- 11–28T freewheel and 42T chainring
That’s a common, proven setup on mid-budget e-bikes, giving you enough range for:
- Spinning comfortably on the flat at 15–20 mph
- Dropping into lower gears for steeper hills
Paired with the motor’s 90 Nm torque, you shouldn’t have trouble starting on inclines or climbing moderate hills with pedal assist.
The fat tires and front suspension help the bike stay composed across:
- Cracked city asphalt
- Hard-packed dirt paths
- Light gravel and park trails
This isn’t a downhill bike, but for everyday “go anywhere” commuting and exploring, the handling package is well balanced.

Who the VIVI ACE07 Is Best For
The ACE07 makes the most sense if you see yourself in one or more of these buckets:
- Suburban or urban commuters who want a comfortable, upright bike that can handle rough pavement and occasional gravel.
- Riders with longer routes (10–30 miles round trip) who value the big 720Wh battery and 25 mph capability.
- Step-through fans who like the ease of mounting, especially when carrying bags or riding in everyday clothing.
- Recreational explorers who split time between city streets, bike paths, and forest or canal trails.
If you want one bike that can cover weekday commuting and weekend fun rides, the ACE07 is built with that versatility in mind.
Who Might Want a Different Style
You may want to look elsewhere if:
- You prefer a super-lightweight bike; at around 72 lb, this is very much a full-size fat-tire e-bike.
- You’re after a pure city bike with narrower tires and ultra-nimble handling.
- You don’t need fat tires and would rather trade some comfort for easier storage or carrying up stairs.
- You want full-suspension for technical singletrack—the ACE07 is front-suspension only and aimed at all-terrain, not hardcore MTB.
For most commuters and casual riders, those trade-offs are reasonable, but they’re worth keeping in mind.
Pros & Cons
Pros
- Long-range 48V 15Ah (720Wh) battery with realistic 25–40+ mile mixed range
- Powerful 1475W peak hub motor with 90 Nm torque for hills and heavier riders
- 26″ x 4.0″ fat tires and 100 mm suspension fork for comfort and stability on mixed terrain
- Step-through 6061 aluminum frame for easy mounting and dismounting
- Shimano 7-speed drivetrain plus 5-level PAS and dual-style throttle control
- Integrated rear rack, full fenders, and kickstand included
- UL 2849 / UL 2271 certified system with IP54 protection
- Multiple color options so you’re not stuck with just one look
Cons
- Heavier than slim-tire commuters; not ideal if you must carry it up stairs regularly
- Fat tires can feel “sluggish” compared to narrow city tires at lower assist levels
- Rear lighting is reflector-only out of the box; many riders will want an active rear light upgrade
- Spec sheet language around “mechanical vs hydraulic” disc brakes is a bit confusing, even though they are disc with 180 mm rotors
Frequently Asked Questions
How far can the VIVI ACE07 really go on a single charge?
VIVI lists a max range of 50–60 miles, PAS range of 34–60 miles, and throttle range of 28–34 miles, depending on mode and riding conditions. In mixed real-world use (stop-and-go, some hills, some throttle, some PAS), most riders should expect around 25–40 miles per charge, which is still strong for a 26″ fat-tire e-bike.
Is the ACE07 good for hills?
Yes—within reason. The 1475W peak motor and 90 Nm torque give it more grunt than many entry-level commuters. Use lower gears, higher PAS levels, and contribute some pedaling, and it should handle typical city and suburban hills without drama.
What about riding in the rain?
The ACE07 is rated IP54, meaning it’s resistant to dust ingress and splashing water. It’s fine for light to moderate rain, as long as you avoid submerging components and dry the bike off after wet rides. As with any e-bike, store and charge the battery in a dry environment.
Does it come with everything I need to commute?
Out of the box, you get:
- Integrated rear rack
- Full fenders
- Front headlight
- Kickstand
You’ll probably want to add:
- A bright rear light
- A lock
- A rack bag or panniers
…but the base package gets you most of the way to a functional daily commuter.
Final Verdict: Is the VIVI ACE07 Worth It?
The VIVI ACE07 is best thought of as a long-range, step-through “SUV” e-bike:
- Big battery
- Strong peak motor
- Fat tires and front suspension
- Practical rack and fenders
- UL-certified electronics
If you want one bike that can cover your weekday commute, weekend exploring, and around-town errands—without worrying about top-tube height or sketchy off-brand batteries—the ACE07 sits in a very attractive spot in VIVI’s 2025 lineup.
It’s not the lightest or raciest e-bike out there, but for riders prioritizing comfort, stability, and go-anywhere versatility, it hits a very solid balance.
