250W E-BIKE CONVERSION KIT
Government has seen fit to adopt the current French standards (EN15194) on
electric bikes; these guidelines show very little foresight into the
Australian bicycle scene but are to be expected from our Nanny leaders. Legal
power is now 250w, but the two main requirements are the electrical system
being speed limited to 25kmh and pedal activated motors…that’s all well and
good and our road legal package will have both the
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 25-26v 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.
Picture for illustrative purposes only, some fittings may be slightly different in the supplied kit
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 an Ebay kit with the basic single sprocket for the front really limits your power as you have no small 34T sprocket to drop down to when climbing steep hills. This is why we don’t bother to offer the cheap steel crank set.
Note: motor mounting bracket in photo is old style, current kits will have sprocket guard included.
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 bottom bracket.
The throttle is now a
We also supply a tough nylon bag that straps under your seat or under the top bar of the frame and can carry up to two battery packs. The photo below shows the complete setup fitted to one of our bikes. With our 22.2v 10Ah battery pack we can maintain 25kmh genuine speed with light pedalling along level surfaces and get well over an hour of constant running from the system. Of course you can pedal faster, but the motor will not assist you above 25kmh in the road legal setups.
Our bikes will climb the steepest fire trail 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 riding on or off road without it! This conversion will pull at around 300 watts under full load but is a rated 250w motor and road legal if all sensors are installed.
One or two of our 22.2v 10Ah EXTREME POWER Lithium-NiCo’ or LifePO4 battery packs. (22.2v is nominal rating used by most factories, fully charged is 25-26v) Using two of our batteries in parallel gives double the run time and the best power output possible, our battery bags are designed to take 2 packs anyway and our batteries are half the price of others!
Our Motor kit is easily mounted on most diamond frame bikes with the supplied mounting bracket set & hardware. The kit is supplied with all parts listed above, we are happy to help via email with any installation issues. We fit plugs for the battery connections and test the complete set on the bench before shipping.
You will need some simple bike tools, a crank puller, a chain press, and a bottom bracket spanner. We will be stocking these tools in the near future; all are available at your local bike shop.
