This is a fat-tire bike designed for cargo or family fun. It is clearly designed for more than just a leisurely ride for one person. It has a 113 kg (250 lb) capacity. The frame is aluminum and the platforms are bamboo.
It is a pedal-assist bike. That means the motor is activated by you pedaling rather than just a throttle. I have a bike like this and much prefer it to the one with just a throttle.
