KITS ARE IN STOCK NOW! DONT MISS OUT OVER THE HOLIDAYS!
2000W+ E-BIKE CONVERSION
NEWS!! Our latest high power
2000 watt kit comes with a new OzEbikes water proof
40A BLUETOOTH speed controller! This controller is small and robust, much
smaller than the old brick style pre-programmed units. Programming is via smart
phone, this allows you to set your cut-off voltage easily for various 36-48v
battery packs and also adjust power levels for extended range when you don’t
need the full capability of 2+Kw. You can run a 36v pack, our 44.4v LiPO packs, or our 48v LiIon
packs without issue, all that is required is the cut
off voltage reset.
Plugs!! We are now running a compact waterproof motor connector plug that
houses both the main power phase wiring as well as the hall sensor wiring, this
has added to the price but the kit is now much more waterproof and less chance
of damaging the fine sensor wiring.
new motor design with completely redesigned winding layout and much larger
diameter rotor has resulted in a unit that can handle up to 3000 watts (subject
to ambient temp and load) and produces more torque at less amp draw! Running at
2000w means the motor is never overloaded and thermal cutout
is almost never experienced!
Our test figures using
our 44.4v (50v fully charged) lithium polymer batteries show 1960 watts max
load with 20% more torque than the old Headline motor produced at 2500 watts!
New gearbox design with Nylon planetary gears reduces noise to a new low, very
quiet running system!
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 external sensored speed controller, designed to run on Lithium
battery packs. The motor runs through a sealed planetary gearbox. The output
shaft runs a standard pitch sprocket that will take 8-9spd chains, and features
a freewheel 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.
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.
New 3Kw hi torque motor with black ISIS crank
set, 40A controller and new LED throttle.
crank-set is the top model ISIS DRIVE
available and is a double chain wheel 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 steel crank sets.
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, the only difference is the
front gears will only change between 2 sprockets, small and large. Our cranks feature a freewheel sprag clutch
as well, this allows you to pedal the bike as a regular bike without any
interference from the motor, or let the motor run without having to pedal.
NOTE: Our standard 2000w Crankset
is built with 44T chain wheels for both motor and main drive, this gives us the
best ratio between the motor and the cranks for a good balance between torque
and speed, this setup can reach 60+kmh on the flat when fitted to a regular 26”
mountain bike, a hybrid or flat bar road bike will usually be faster. My 26”
test bike has done 64kmh into a strong headwind running the 14/44 ratio. We can
also build custom cranks with various combinations of chainwheel.
Note: Buying a kit with a single sprocket for the front
really limits your climbing ability as you have no small sprocket to drop down
to when climbing very steep hills. This is why we don’t bother to offer a basic
crank set that other sellers include as standard.
MOTOR DRIVE SPROCKET
We supply a new
custom made 14 tooth sprocket on this motor, this is a new freewheel with
stronger pawl mechanism forged in chromalloy and with
the screw on cover spot welded to ensure it cannot unscrew. 14T is a good balance
between speed and torque, and with the rear gearing you get the best of both
MOTOR MOUNT & BOTTOM BRACKET
We supply a
special triple bearing sealed cartridge bottom bracket with an extended axle so
that your left pedal clears the back of the motor housing. The bottom bracket
is standard English fitment and is adjustable 68-82mm
long via a new long left hand cone to support the motor mounting plate. It will
fit all older bikes with an English BB and many newer bikes that have an
external bottom bracket that screws into the frame,
68-82mm is easily covered. We also have
custom bottom brackets with 170 and 190mm long axles that are suitable for most
Downhill frames and even FatBike frames which have
very wide 120mm BB’s! The motor mount for the 2000W
kit 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.
NOTE: We assemble all motor mounts before shipping, when you are ordering
from us you will be asked questions about the width of your bikes BB frame tube,
and for photos of your bike so we can make sure the motor assembly is a drop in
fit. There are a couple of hours of work involved in setting up each kit but I
feel this is necessary in order to offer the customer a tailor made conversion
that requires minimal work to install.
BLUETOOTH SPEED CONTROLLER
controller supplied is our OzEbikes sensored brushless 40A BlueTooth
controller rated at 40A continuous with an 80A burst rating. This new
controller is waterproof and can be set for voltage cut off inside. It has no
power ramp down as your batteries get low like some controllers; it will
provide full power right up to cut off. We recommend the cut off be set to 43v
minimum with 12s lipo, this helps to protect our
battery packs while still allowing you to use 85% of available capacity. It is
very important you do not drain your lithium batteries too low, you can damage
the cells, as soon as you hit cut off the first time you should stop using the
Again we do the hard work, your Controller comes pre-wired with new
WATERPROOF connector for motor and an XT90-s Anti-Spark plug for battery
connection, you will receive a series harness for your
batteries if you are ordering batteries with the kit. All unused connections
are insulated out of the way, connection is simple. We suggest using one bolt
to one of the drink bottle mounts on your frame with a tie strap at the other
end of the controller. We remove unnecessary plugs and use quality silicon wire for the main power input.
We supply a YBN
Heavy duty MACK Half Link chain for your motor to crank drive, these
chains are very strong and long lasting, the half link allows more accurate adjustment
of chain slack and is much stronger than the best conventional chain available.
Our chain is the compact 8spd 3/32 size not the wide heavy 1/8th BMX
The throttle is thumb operated and will work with
your existing grips. All the wiring is pre terminated and simply plugs
together. There is a key switch so that you can switch the system off and an
LED readout showing battery voltage. This new throttle makes it easy to know
where you batteries are at, once your batteries drop to 43-44v under load you
should stop using them and swap over or recharge. Pushing them lower in voltage
risks damaging cells.
NOTE: Most electric throttle housings interfere with Shimano gear levers, we
recommend swapping your shifters to our Sunrace rapid
fire as both levers are at the back, we have 6, 7, 8
and 9spd available. If you have SRAM shifters you are usually good to go, all
that is needed is to trim the raised section of plastic off the top of the
large lever so it better clears the throttle casing.
With 44.4v 12Ah battery packs the 2000W bike below has reached 64kmh on
the flat with a 100kg rider! Due to the high torque and power full throttle is
not needed as much with this setup, I have calculated that riding around
25-30kmh average speed with pedalling our 12Ah battery set will get 35km range,
maybe even more, its very hard to predict due to rider style and terrain, wind
TEST RIDE DATA
Our 2000w test bike, full throttle settled
power recorded on the Batteryman meter is 1960 watts
when running our 16Ah 12c 44.4v lithium polymer batteries. One of my harder
tests is a 16km run that has long steep climbs in both directions, I do this
ride using the motor almost the entire time, usually at full throttle with
light pedalling. With the new setup I managed 30mins and 7500mah consumed from
the battery packs, a very impressive real world result.
shows our optional LUNA frame bag fitted up, this bag will carry up to four
12Ah Lithium Polymer battery packs, and will easily carry our 48v 16Ah pack as
well as water bottle and other things, it’s the best value bag on the market
and gives great balance to the bike as well as looking good. You can find the
bags on our bag page.
Our new LiIon NMC
48v 16Ah battery pack is made for this kit! With a 40A constant BMS built in,
the new battery offers a compact hi capacity solution that will actually handle
the power of our mid drive kit. Of course you can still damage a battery,
running the bike at full power ouput constantly will
risk tripping the BMS and in severe cases you could burn out the output stage
of the BMS. There is very little chance of this happening, but we like to be
informative and have seen users do all sorts of crazy things with batteries
over the years!
You can also use Lithium Polymer battery packs
similar to what the use in large drones and UAV. You might already have our old
setup for these. Two 6 cell batteries are connected in series for 44.4v
nominal, 50v fully charged. We are happy to source replacement batteries for
those who have this setup and the charger/s to suit, but we wont
be selling them as a general stock item anymore as we are invested in the new
technology of our NMC LiIon battery packs.
Our 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
high power Electric Assist setup like this you will never go back to riding off
road without it! Our system will peak at around 2000 input watts on 44.4v
batteries, we have measured this in real time with our E-meter equipment,
unlike other sellers we deal in electronics daily and have an extensive
workshop for testing and fabrication.
freewheel clutches in our cranks and motor drive are good quality and made in
Taiwan, don’t be scared off by talk that these clutches fail quickly, my own
has been running for over 2 years regularly, and these clutches stand up to the
torque of the 2000W system without trouble. In the event you manage to wear or
break one of the free wheels they are available as spare parts for an enormous
$33.00 each! J
