1 × Hub Motor, Motor Controller, throttle (preferably thumb, not twist) I'm using a 'kit' from ebay that contained all of this.
1 × Bike Frame: With 3" or bigger tires
1 × XT60 Connectors Seriously, these are awesome.
1 × Zip ties, electrical tape, hot glue I really should take up stock in these...
1 × Cells. Lots and lots of 18650 cells. Havested cells from laptop batteries headed to the landfill. Be sure to test them carefully if you do this. More on that later.
