Super73 RX Mojave 72 Volt 50 MPH Stock Motor Upgrade . 1/4 Mile Test.

In this video I am doing testing on the new 72V conversion I did using a Grin Phaserunner. You can now use the franken runner sold by them and do this conversion. I have the full how to video in editing and will be uploading soon. If you have not yet already subbed please do now to be notified. Do not waste the time, and money on going mid drive when you can repower your stock motor. Also, Did your stock controller fail? You can use this controller with 36V all the way up 72V. Stock was tested all stock at full charge. 72V is 20S2P tank battery I made Controller is Phaserunner by Grin.
