Vivi ACE01: 1475W Motor, Fat Tires, and More – Our Honest Review

1.2K

Electric bikes have become a game-changer for commuters, adventurers, and casual riders alike, blending the joy of cycling with the ease of motorized assistance. Enter the Vivi ACE01 Electric Bike—a beast of an electric mountain bike built for adults who crave power and versatility. With a 1475W peak motor, 26″ x 4.0 fat tires, and a 48V 15Ah removable battery, this e-bike promises to tackle everything from city streets to rugged trails. Launched recently by Vivi, a brand recognized for crafting dependable and innovative e-bikes, the ACE01 has quickly made waves for its robust design and all-terrain capabilities.

What sets this bike apart is its ability to deliver a thrilling yet practical ride. That 1475W peak motor churns out 90Nm of torque, propelling you to a top speed of 25 mph—plenty of oomph to conquer steep hills or cruise through rough terrain. The fat tires grip like a champ on sand, snow, or gravel, while the torque sensor ensures the power kicks in smoothly, matching your pedaling effort. Vivi rolled out the ACE01 as a fresh addition to their lineup, and while it’s still new, it’s already earned UL 2849 certification for safety—a big deal for peace of mind. Since its debut, minor tweaks have improved the user experience, but the core of this bike remains a testament to rugged, reliable engineering.

The company Vivi has a great reputation in the field of electric bicycles. They’re known for blending quality construction with rider-focused features, catering to everyone from daily commuters to weekend warriors. Based on my time with the ACE01, it’s clear Vivi poured their expertise into this model. It’s not just about getting from A to B—it’s about enjoying the ride, whether you’re dodging potholes in town or kicking up dust on a mountain path. This bike feels like a natural extension of their mission to make e-biking accessible, safe, and downright fun.

Is Vivi ACE01 for You?

The Vivi ACE01 is built for riders who want an e-bike that can do it all. It solves the problem of needing a single ride for multiple scenarios—think commuting to work, hitting off-road trails, or just unwinding with a scenic cruise. This bike shines for adults who love variety in their rides. If you’re someone who gets a kick out of exploring diverse terrains or needs a dependable option for longer trips, the ACE01 has you covered. It’s also a solid pick for those who want a bit of exercise without the full grind of a traditional bike.

That said, it’s not for everyone. If you’re after a super-light, foldable e-bike to zip around tight city streets or stash in a small apartment, this might feel like overkill. The fat tires and hefty build cater more to adventurers than urban minimalists. Budget-wise, it sits in the mid-to-high range—not a cheap starter bike, but a worthwhile investment for the features you get. Beginners will find it approachable, though. The controls are intuitive, and the five riding modes let you ease into the experience at your own pace.

What We Like About Vivi ACE01

Riding the Vivi ACE01 feels like unleashing a powerhouse. That 1475W peak motor is a beast, effortlessly hauling me up steep inclines and across rough patches without breaking a sweat. Paired with the 48V 15Ah battery, I’ve clocked 40-60 miles on a single charge—perfect for long rides without range anxiety. The 26″ x 4.0 fat tires are a dream on tricky surfaces. Whether I’m rolling over sand, snow, or loose gravel, they grip tight and keep me steady, making off-road jaunts a blast.

The torque sensor is a quiet hero here. Unlike some e-bikes with clunky cadence sensors, this one reads my pedaling effort and doles out power so smoothly I barely notice the assist—it just feels natural. Stopping power is another win, thanks to the dual hydraulic brakes. They bite hard and fast, even at 25 mph, giving me confidence on descents. The adjustable suspension fork soaks up bumps like a champ, and the 7-speed transmission lets me tweak gears for any situation. It’s a setup that’s tough to beat for the price.

What We Don’t Like About Vivi ACE01

No bike’s perfect, and the ACE01 has its quirks. It’s heavy—there’s no getting around that. The big battery and motor make it a chore to lift or maneuver when I’m not riding, like when I’m wrestling it onto a rack or up stairs. For a mountain bike, that’s expected, but it’s still a hassle. The fat tires, while awesome off-road, feel a bit much on smooth pavement. They add some drag, and I wonder if slimmer tires might’ve been a better fit for my mixed riding.

The size can also be a drawback. It’s not the most compact e-bike, so storing it in a cramped space takes some planning. For me, the trade-off is worth it for the performance, but if you’re tight on room or only ride in the city, it might give you pause. It’s not a dealbreaker—just something to weigh against your needs.

Pros & Cons

Pros	Cons
1475W peak motor crushes hills	Heavy build can be tough to handle
40-60 mile range per charge	Fat tires overkill for paved roads
Fat tires excel on all terrains	Bulky size not ideal for small spaces
Smooth torque sensor assist
Hydraulic brakes stop on a dime
Adjustable suspension for comfort
UL 2849 certified for safety

What’s Included?

I’m impressed with how straightforward the setup is—85% pre-assembled means I was riding in under an hour, even with my questionable mechanical skills. The 3A charger juices up the battery in 4-6 hours, and I love that I can pop it off to charge indoors. That said, I wish they’d tossed in a rear rack or fenders. For a bike this versatile, those extras would’ve been clutch for commuting or wet rides. It’s a solid package overall, but those omissions sting a little.

The torque sensor and hydraulic brakes make it a joy to ride, while the UL 2849 certification seals the deal on safety.
