I got this e-bike and I love it. Good power and battery size for the price.
Please note that this is terrible as an actual bike. There are no gears, so pedalling at 30 km/h does not do anything. Luckily, you don't have to pedal :P
If you run out of battery, just give up and Uber home, because you won't make it otherwise.
It's a very comfortable ride, with the suspension and the thick tyres.
The warranty section tells you how to make the bike better.
Warning: The laws surrounding legal use of electric bicycles differ between states. The peak power of 400W for this model may exceed maximum allowed wattage for your state. Please check the relevant laws for your state and proceed at your own risk.
