BUILT IN CONTROLLER 500W
E-BIKE CONVERSION
Our kit comes with everything you need to convert a
regular Diamond framed bike to electric power. We use a custom 3 phase
brushless in-runner motor with built in sensored speed controller, designed to
run on Lithium battery packs that measure 25v fully charged. The motor runs
through a sealed planetary gearbox. The output shaft runs a standard pitch
sprocket that matches most bike chains, and features a sprag clutch built in,
this allows the motor to drive the bikes gear system without you pedalling, or
sit idle with no load on the gear system while you pedal.
The
combination of high torque 3 phase brushless motor, planetary reduction gearbox,
and the direct drive through the bikes own gear system results in a bicycle
that is very versatile and has very hi torque, able to climb steep hills
through the low gears or cruise along on
the flats at a rapid pace with only light pedal input! Overall power is many
times more than any hub motor setup can produce, and that power runs through
your gears, unlike a hub motor that has a single geared speed.
CRANK SET
The supplied crank-set is the top model available
and is a double chainwheel plus drive sprocket for the motor. The outer
sprocket is spaced further than a regular crank set and runs the drive chain
from the motor. The second and third sprockets are the main gear sprockets and
carry your existing main chain to the back gear cluster. Our outer and inner
sprockets are the more expensive heat treated alloy, saving almost 500g in
weight over the regular cranksets. So what you end up with is 2 main sprockets
at the front much like your original gear system, your derailers will operate
all the gears as normal once the front one has been adjusted to suit 2
sprockets, the only difference is the front gears will only change between 2
sprockets, small and large.
Note: Buying a kit with a single crank sprocket for the front
really limits your power as you have no small sprocket to drop down to when
climbing steep hills. This is why we don’t even have the option of single
chainwheel crank set. Of course on bikes which can only have one front
chainwheel we can assemble custom cranks to suit!

We supply a sealed
bottom bracket with an extended axle so that your left pedal clears the back of
the motor housing. The bottom bracket is standard 68mm cups and will fit most
older bikes and many newer bikes that have a regular screw in bottom bracket.
THROTTLE CONTROL
The throttle is a twist grip much like a motorbike
and comes with matching rubber grips for your handlebars. All the wiring is pre
terminated and simply plugs together. There is a power switch on the throttle
assembly so that you can switch the system off and a 3 stage LED light system
to show the battery capacity.

With our 22.2v
12Ah battery pack we can maintain 25-30kmh genuine speed with light pedalling
along level surfaces and get well over an hour of constant running from the
system.

bike, note the bag under the seat is not included in the kit and is no longer
available, we have the LUNA triangle bag that goes inside the frame now.
Our hi powered
bikes will climb steep fire trails on their own in low gear, or you can power
up a trail by pedalling and running at full electric power, once you have
experienced a quality Electric Assist setup like this you will never go back to
a regular bike! The 500w motor will peak at around 750 watts power consumption
under full load to get the rated 500+w output.
BATTERY
REQUIRED:
One of our 22.2v 14Ah EXTREME POWER Lithium-Polymer battery packs (22.2v
is nominal rating used by most factories, fully charged is 25v) will give you
good range with a 500w system, the 500w motor will pull around 32 amps max at
full load and usually sits around 10 amps when used liberally with light
pedalling. At 10 amps you will get around 70 minutes continuous running with a
safe reserve in the battery, usually this will equate to 30-40km distance, often
more when it’s largely flat terrain, its very dependant on your use of
throttle! You can carry 2 or even 3 batteries on your bike and simply swap over
as your current battery gets low. Our LUNA battery bags are designed to carry
2-3 packs and our batteries are affordable as they don’t run internal balancers
or output regulation, our chargers do all the balancing and maintenance of the
battery.
INSTALLATION
We fit plugs for the
battery connections, assemble the motor mount to your bikes BB width, and test the
complete set on the bench before shipping. The motor mount for all our kits is
a new design that hangs off the bottom bracket and helps to reduce the issue of
mount and frame flex from the high torque our motors produce. It also allows
fitment to many suspension bikes and bikes with odd shaped frame tubes that
would normally not accept the alloy clamp mount. The chain tensioner is a new
design with a coil spring that is easier to install and adjust the chain
alignment. You will need some simple
bike tools, a crank puller, a chain press, and a bottom bracket spanner. We
usually stock these tools, and all are available at your local bike shop.
