For those curious about why some of these bikes can be so powerful (besides the fact that the bike itself is very light compared to a car), it's because an electric motor delivers nearly 100% of it's maximum torque constantly. What's amazing is that it can do it at nearly 0rpm. That's like jumping on your bicycle and having the muscle to storm up Mount Everest without breaking a sweat. You can't do it, but an electric motor can. A gasoline engine will only begin to deliver this level of torque when it's spooled up, and even then, only does it for a limited time of the overall rpm range. (And that is why most trains run on an electric motor!)
