Review
The ACE01 is Vivi's do-it-all fat-tire e-bike: 26x4.0" tires for grip on almost anything, a 750W motor (1500W peak) putting out 90Nm of torque, and a torque sensor that reads how hard you're pedaling to deliver smoother, more natural assistance than the simpler cadence sensors found on cheaper e-bikes.
The 720Wh removable battery (48V 15Ah, 21700 cells) is rated for 40-60 miles depending on mode — real buyers report similar real-world numbers, with one long-term reviewer logging over 900 miles. Dual hydraulic disc brakes and an adjustable, lockable front suspension fork round out a build that's clearly aimed at riders who want one bike for commuting and light off-road use alike. At 72 lb it's a heavy bike, typical for this fat-tire class, and it supports riders and cargo up to 330 lb combined.
Amazon reviewers are largely positive — 4.5 out of 5 stars across 96 ratings at the time of writing — praising the smooth ride, snow performance, and value for money. The most common complaint is occasional quality-control issues out of the box (a missing washer, air in a brake line on one unit), which a couple of buyers had to sort out with the manufacturer.
Pros
- Torque sensor gives smoother, more natural assistance than basic cadence sensors
- Dual hydraulic brakes and lockable front suspension — solid stopping power and comfort
- Large 720Wh removable battery with real-world range matching the claimed 40-60 mi
- High 330 lb combined weight rating — works well for heavier riders
Cons
- Heavy at 72 lb, awkward to carry up stairs or lift onto a rack
- A handful of buyers reported quality-control issues on arrival (missing hardware, air in brake line)
- Top speed isn't clearly stated by the manufacturer
Ideal forRiders who want one fat-tire e-bike that handles pavement, gravel, sand and snow equally well, including larger or heavier riders.
