This motor consists of technology that has been around for over a century and is very simple in design. It has a positive wire going into the motor, and a negative wire coming out of it, and is driven by a single phase electrical pulse sent from a Controller. Inside the motor, mechanical brushes and a commutator (armature) switch the pulse of electricity back and forth to create a "push-pull" magnetic field in the coils, which are in the center of the motor. As a pulse of electricity is sent to the motor from the controller, the coils create a strong magnetic field, which repulses them from the magnets that surround the coils, and causes the motor to advance (rotate) away from the magnets - making the motor spin…. The only moving parts - parts that can wear out - in this motor are the brushes and the center bearing. The brushes will last somewhere around 7,000 - 8,000 hours, which should give a minimum of five years use before they need to be replaced… This motor is very rugged, durable, and requires simpler electronics than a BrushLESS motor. It can accept varying voltage from 24 volts up to as high as 72 volts, provided that you have a controller that is capable of running it at the higher voltages without burning up.

CONTROLLER:
How does the controller determine the speed at which the motor rotates?
The pulses of electricity sent to the hub motor are determined by the throttle, which is mounted on the handlebars of your bicycle. The throttle is actually just a magnet passing by a "Hall Effects Sensor." Power is supplied to the throttle from the battery. The throttle then rations a small amount of power: from 0 to 5 Volts, which it sends to the controller. The amount of voltage sent to the controller is determined by how much the throttle is twisted. As the throttle is twisted, "Hall Effects Sensors" read the amount of voltage, and send this amount of voltage to the controller. 5 volts means the controller does nothing: sends no pulses to the hub motor, 0 volts means the controller sends electrical pulses to the hub motor as fast as it can.

BATTERIES:
The Bike Electrified is a 36 Volt system. In your battery pack (which mounts on the rear rack of your bike), there are 3 - 12 Volt batteries connected in series, which adds up to 36 Volts. These are sealed, gel-cell, lead acid batteries. Lead Acid Batteries need to be recharged immediately after EVERY use. They hate to be left in a discharged state, even if they are only slightly discharged. I repeat, THEY HATE TO BE LEFT IN A DISCHARGED STATE! So, if you forget to recharge your batteries, leaving them drained for even one day, you WILL damage them, and they will soon begin to give you poor performance.
