A well-equipped folding ebike with genuine range and useful extras like cruise control, but assembly quality and manual clarity are inconsistent enough to budget extra time or a shop visit.

More from this brandAll Vivi electric bicyclesOverview
A 20 inch folding electric bike with a 500W motor (750W peak), a removable 48V 374.4Wh battery rated for 22 to 50 miles depending on mode, cruise control, dual disc brakes and IPX7 certification to UL2849.
The bike ships about 85 percent assembled, and reviewer experiences with the remaining assembly split sharply, some found it straightforward and others called the printed manual confusing enough to need real bike repair experience. Most owners who stuck with it after setup reported strong battery life and an easy fold for storage in a closet or car trunk. A minority ran into hardware failures, including a kickstand that snapped at the weld and a stripped pedal arm, with after-sale support quality varying by report.
- 500W motor, 750W peak output
- Removable 48V 374.4Wh battery
- Up to 50 miles range in assist mode
- Cruise control and dual disc brakes
Who it's for
Fits a rider who wants a folding commuter ebike with real battery range and is comfortable doing final assembly from a manual, or has a bike shop finish it. Not a good match for someone who wants a bike ready to ride straight out of the box with zero setup.
Pros and cons
- Genuine battery range across charge modes
- Folds down for closet or trunk storage
- Cruise control holds speed hands-free
- Assembly manual described as confusing
- Some hardware failures reported, kickstand and pedal arm
Performance notes
Cruise control lets the bike hold a set speed without pedaling or holding the throttle, and dual disc brakes are paired with a 7-speed drivetrain, though one rider could not get the top two gears to engage.
