Overview
Vivi positions the ACE01 as an aluminum frame fat tire ebike for trails and city use, with a front suspension fork and a trigger-shifted derailleur. A torque sensor reads pedal effort, and an LCD display shows five working modes.
Wide tires and a lockable fork soften rough ground, and hydraulic brakes handle the weight. Motor and battery figures agree with each other in the specs, but the title peak power is a separate claim. The listing gives mixed warranty wording.
Who it's for
Adults riding mixed pavement and dirt who want pedal-effort assist. Shorter riders and anyone carrying the bike regularly should check the minimum height and weight first.
Pros and cons
- Torque sensor assist
- Dual hydraulic disc brakes
- Lockable front suspension fork
- Wide fat tires
- Heavy for lifting
- Warranty listed as implied
- Height minimum excludes shorter riders
Performance notes
A torque sensor measures how hard the rider pedals and scales motor output to match, so assist feels proportional rather than on-off. Fat tires lower pressure on loose ground, and the lockable fork can be stiffened for pavement.
