Which is better for commuting?

The VIVI. Its 500 W motor, 21-speed gearing and 26-inch wheels suit paved commuting, and it has 573 ratings at 4.8 out of 5. The GT900's suspension helps on broken pavement but its 24-inch wheels and 400 W motor are less suited to distance.

Which handles rough trails better?

The GT900. Front and rear suspension absorbs potholes and gravel, and buyers report the 748 W peak motor climbs fire roads well. The VIVI is a hardtail, so rough ground reaches the rider directly.

Which has more range?

The GT900 has the larger battery at 468 Wh versus 374 Wh. Real-world reports put the GT900 at about 30 miles mixed and 18-25 miles on trails with high assist. The VIVI claims 50 miles but lists 35-40 km realistic range.
