Today we upgrade and modify my 72v Razor SX500 e-bike mini motorcycle to be EVEN FASTER THAN IT ALREADY WAS! This new electric motor controller takes the bike from 3000w watts peak to over 8000w in a tiny electric pit bike! Thanks to surronster for inspiring this video with his own MX650 upgrade - this is an upgrade option for Razor owners looking to build a 72 volt, high voltage system on their own electric dirt bike or e-bike without breaking the bank :)

PARTS TO UPGRADE YOUR OWN RAZOR SX500 RSF650 MX650 or MX500 (or other bike): linked in comments!

This is my first electric bike build / project, so I hope you enjoyed the video!
