"It sells a motorcycle's spec sheet but delivers a large battery on a dangerously under-built frame."
The '9000W' figure is not real-world power; it's a misleading peak number. You are buying a bike with a very large battery whose actual performance is limited by cheap controllers and is unsafe at its claimed maximum speed.
This product is for DIY builders who might salvage the large 1920Wh battery and hub motors for a custom project where the price-per-watt-hour is the only concern. It could also be considered by experienced riders who plan on immediately replacing the brakes and other critical components.
Anyone seeking a safe, reliable vehicle for commuting or recreation should skip this. First-time e-bike buyers attracted by the extreme numbers are particularly at risk, as the chassis and safety components are not engineered for the advertised performance.
