Build a BIKE for you, not for them ! (the oil companies!)
                                                
The motor uses a higher voltage,
lower current design to minimize
losses from wire heating.
It is able to
achieve 10KW continuous and up
to 30KW peak.
The motor is
thermally protected when using the
recommended Kelly Controller to
prevent overheating and burn out.
The Hub motor is designed for
motorcycles weighing less than 400
pounds with the batteries (dry weight,
no rider).


The Hub motor will come laced to
DOT compliant rim, WM3 style 36
hole, 18 X 2.15, other sizes available
on special order, or order just the
motor and have a rim of your choice
spoked onto the motor.
The EnerTrac hub motor is arguably the most powerful and readily available hub motor
currently for sale for gas to electric motorcycle conversions
.
This motor was designed to make the gas to electric motorcycle conversion easy,
with such features as a 60mm O.D. hollow axle designed to accept the standard bolt
axle used in almost all motorcycles. Unique to a motorcycle conversion using a hub
motor is the design of a torque arm that prevents the axle from rotating. Our Torque
Arm was designed for direct integration into most motorcycles swing arms. Other
features of this design that stand out when compared with other hub motors are large
mounting area and easy mounting of a Disc Rotor,
plus high efficiency design.
MOTORCYCLE HUB MOTOR model M602
Two turn winding motor

Power output: 10KW continuous @ 25c ambient temperature

Protection: thermally protected with kelly controller

Typical Voltage needed:
72 volts for 45 MPH with 18 X 3.5 tire
96 volts for 60 plus MPH with 18 X 3.5 tire

Typical current demand:
At 72 volts and 45 MPH < 50 amps
At 96 volts and 60 MPH < 95 amps

These voltage and current results were obtained using a 325
pound motorcycle with a 170 pound rider on a flat road with
little to no headwind your results will vary depending on
motorcycle, rider weight, and conditions. EnerTrac does not
guarantee voltage and current specifications, but provide them as
a guide to help the customer chose the correct battery for their
build.

Swing arm width needed:
7.5 inches needed for installation
                with torque arm

Wheel size: WM3 style 36 hole 18 X 2.15

Color: Motor Black, Rim Silver
MOTORCYCLE HUB MOTOR model M603
Three turn winding motor

Power output: 10KW continuous @ 25c ambient temperature

Protection: thermally protected with kelly controller

Typical Voltage needed:
72 volts for 30 MPH with 18 X 3.5 tire
96 volts for 45 plus MPH with 18 X 3.5 tire

Typical current demand:
At 72 volts and 30 MPH < 33 amps
At 96 volts and 45 MPH < 50 amps

These voltage and current results were obtained using a 325
pound motorcycle with a 170 pound rider on a flat road with
little to no headwind your results will vary depending on
motorcycle, rider weight, and conditions. EnerTrac does not
guarantee voltage and current specifications, but provide them

TYPICAL INSTALLATION
BRAKE COMPONENTS ARE AVAILABLE!
SPECIFICATIONS
               Two motors are available, models M602 and the M603

The basic difference between the 602 and 603 are as follows:

The 602 is 10 RPM/volt                       The 603 is 7 RPM/volt

The 603 has 30% more torque for the same current as the 602 but 30% less speed

The extra torque lower speed 603 is ideal for off road dirt bikes

For a road bike that is less than 400 pounds (no rider) we recommend the 602 running at 96 volts
(32 cell LIFEPO4 battery pack) 40AH or greater this will result in a bike capable of over 100 Kph

Both motors are 92% efficient when running at the proper RPM and load.  
It is important to note these motor are Brushless permanent magnet motors and as such require a
specific kind of controller designed for this type of motor.

One recommended controller is the Kelly Controller KBL12401I unit. There are several others
depending of your needs.   
 We have controllers available!
