Last year Paradox Kinetics sent me a kit to convert any bike into an electric bike with a massive 1000Wh battery and awesome carbon fiber electric motor! It has 1500W output and 1800 peak power, which should be good for almost 45 mph! But is it any good, is it powerful and mainly, will I be able to fit it onto my downhill bike to make the ultimate mtb trail smashin e bike?
