The Vivi is a fat-tire electric mountain bike built around 26 x 4-inch tires, a rear hub motor and a large removable 48V battery. It pairs an aluminum frame and an 80 mm front suspension fork with a 7-speed drivetrain, so it handles sand, snow, gravel and rough trails better than a commuter e-bike with narrow tires. It is UL2849 certified and rated for a 150 kg payload. Riders who want a heavy-duty all-terrain e-bike at the value end of the market are the target; it is heavier and less refined than premium fat-tire models, and its real-world range falls well short of the headline figure.

This is a 26-inch fat tire electric bike with a rear hub motor and a removable 48V 18Ah (864Wh) lithium-ion battery. It has a lightweight aluminum alloy frame and an 80 mm suspension front fork to reduce bumps. The bike is UL2849 certified.
The 26 x 4.0 inch puncture-resistant tires are made for surfaces such as sand, snow, gravel, dirt and rain-slick roads. Front and rear fenders are included. A 7-speed transmission helps with climbing, and dual disc brakes handle stopping.
You can ride with the thumb throttle, pedal assist, cruise control or assist push mode, or turn the power off and pedal like a regular bike. The LCD display shows power, odometer, mileage and speed, and the pedal-assist levels can be customized up to 3 modes. An LED headlight and an electric horn are built in.
