This 5304 Crystalyte rear hub motor package with disk brake mount includes an ultra powerful 36-48 Volt 35A brushless controller (12xAOT460 mosfet, ON/OFF button and CA and ebrake connectors) & a twist grip throttle.  That's everything you need except a 36-48V battery and a bike! It is 3-phase brushless DC, devices and are prelaced in a 26 inch rear bicycle rim, we can get 24 and 20 inch sizes as well!  The Crystalyte 5300 or X5 motors are the most powerful bicycle hub motors we could find, easily able to operate in the 600-2000 watt power range.  All of our hub motors come with Anderson Powerpole connectors for the 3-phase power lead, and a 5-pin male JST-SM series connector for the hall signals, and are plug-in compatible with the brushless bicycle controller.  They are appropriate for applications that require maximum hill climbing and hauling capabilities, for fast vehicles that need significant torque to sustain their top speed, or for heavier riders. The considerable mass of the 5300 motor (20lbs) means that it can absorb a lot of energy without overheating, making it a favorite hub for racers and people looking to push the limits of ebike power output.  In early 2009 Crystalyte improved the waterproofing with rubber seals over the axle. There are a range of windings from a super fast 5302 down to the much slower 5305.
