NEW 2012 pricing and New products release
Our AFT 500w 24v Brushless Geared centre Crank drive give you that extra speed and torque need to go hill climbing offroad use only.
If you work in the city, ditch the second car and ride to work and save up to ~ $800 per month for insurance, registration, parking costs, fuel cost , depreciation of motor vehicle etc. With these savings per month the payback of an electric bicycle can be as short as a few months time !
Quote : "The figures showed that if a 45-year-old ditched a car for a bicycle and saved the money into an account with 6 per cent interest, the person would save $358,000 by retirement age. For a person aged 25, the saving would be $1.04 million.
Contact us and we can send you a copy of this recently published news article in Melbourne.
We also have available 200w, 500w motors at 24v .
And for the most demanding race and offroad conditions we also have available a massive power 960watt 36v Motor in the same size format.
All our motors are of modular mounting construction from the 200w 24v internal motor to our 960w external controller motor

DON’T SETTLE for any other cheap low quality EBIKE kits, settle for the best and have the choice of using it on your favourite bicycle.
Most ebikes on the market today are of very low quality and also use heavy components compared to most mid to high end road bicycles. By using your own or choosing the bicycle yourself you can get the best of both worlds!
To assess the quality of an electric bicycle, one would normally assume the heavier the better ! But in reality it proves the opposite. It’s quite easy to make a bicycle with low quality components that are bulkier and heavier. But it is a lot harder to make a bicycle lightweight and durable at the same time. Most cheap ebikes available on the market today fall into this category.
Also since motor assistance is only allowed to be relatively low to get the best speed, range and response out of your bicycle, it needs to be as efficient and light as possible. This is why we recommend a quality known brand name bicycle like the Apollo brand mountain bike that retails around $5-600 AUD as a minimum. We have used this in our comparison table below Total weight ready to ride vs today’s competitors e-bikes: (AFT mid drive conversion is in red)
Our kit is comprised of the best quality components sourced globally and custom engineered for Australian road use.
COMPLETE Installation KIT includes all the hardware you need to install this kit onto your bicycle. If you don’t have the special tools to install it, we have them also on a 2 week tool rental -see sales options below. To make installation even easier we will also provide detailed colour Step by step photo instructions on how to install this kit. Nearly anyone can install this kit with these instructions (it’s that easy!), but we do strongly recommend that a qualified bicycle technician performs this installation.
Brushless motor has higher efficiency per weight than brushed motors and there is no brushes to wear out , so long term service costs are lower.

USES ALL EXISTING BIKE GEARS in assist mode, Hub motor conversions only use 1 gear for the ebike motor, some other central drive kits only utilise 1 of the front gears. Our kits uses 2 front gears and all of your rear gears. For climbing very steep hills and accelerating quickly you need these gears, especially since in Australia the 200w power limit is quite low. You need all the torque a 200w motor can produce, and peak torque is most often at mid to high rpm of the motor. With this kit you simply change gears to allow the motor to speed up and provide more torque than you can with a single speed hub motor. Single speed hub motors cannot do this they suffer from SLOW acceleration, low hill climbing ability and VERY bad efficiency i.e high power consumption per km.
Crank freewheel allows pedalling flexibility . This means the pedals do not always need to spin with the motor, you can pedal if you want to. You can let the motor do all the hard work and sit back and relax or if you like to get more exercise you can reduce the throttle input and pedal more to get a more physical workout.
Low and central centre of Gravity, other electric bikes have the motor on the hub, either in the front or rear wheel, which affects the weight balance and manoeuvrability of the bicycle. Our Drive System has the motor and gearbox centrally and low in the frame to evenly distribute the weight as low and central as possible. Hence the bike will feel more like a traditional bike, which is also more important at high speed. Additionally we recommend using our light weight performance Lithium ION bottle batteries option to provide even better Low centre of gravity, as it’s mounted inside the frame.
Complete with a new Cartridge sealed bottom bracket that allows fitting to nearly all bicycles, our sealed cartridge bottom bracket is far superior to our competitors who you use a simple open axle and exposed bearing that are easily contaminated and due to the high load of an ebike these bearings can quickly fail.(If you have an ISIS style please contact us )
Our exclusive optional AFT Cycle Analyst has cruise maximum speed limiter and Max power current draw option . This is a plug and play module that gives motor assistance flexibility, for example if you would like your children to safely use the bicycle you can set the maximum speed or power lower then maximum to provide a safer more controlled assistance, or to extend your distance range, or if you would like more of a work out.
We are a registered Australian engineering business and will provide Tax invoice so you can buy with confidence.
The motor controller has built in low voltage cut-out to protect your batteries from too deep discharges. Controller also has over temperature thermal motor cutout for protection.
SUITABLE FOR MOST bikes except
Frame design limitations:The kit is easily mounted on most diamond frame bikes with the supplied mounting hardware. The large angle downtube must be of ROUND shape profile and with a diameter smaller then 55mm to fit this kit. The kit is supplied with all parts listed below. The cartridge bottom bracket we supply suits 68mm bottom brackets. Other bikes may need some modifying and/or use our custom motor bracket spacer. Also some bikes that have unconventional suspension geometry mounts in the location where the motor mounts may not be suited. If you are not sure send us an email picture of you bicycle to confirm if it suits contact us prior to purchase.
Tricycles, Recumbents bikes folding bikes, dropped handle bar bikes and some rear Suspension bikes may have non conventional frame design so please contact us and send pictures of your bicycle.
Gear Shifters Limitations: because the kit uses a twist grip throttle, it is not possible to use on bikes that have twist grip gear changers. You can though quite easily change to a conventional trigger design if required with the help of a local bicycle shop.
Front Derailleur limitation: some bicycles have short throw front derailers that may or may not engage top gear correctly, hence a change to a longer throw derailer maybe required with the help of a local bicycle shop.

Volts, Watts, Amps:The instantaneous electric power being drawn from the battery.
Amp-Hours, Watt Hours:The net energy that has been pulled from the pack since the meter was reset. The accumulated amp-hours let you know the remaining energy in the battery pack with far greater accuracy than a voltage or LED indicator.
Speed, Distance, Time:All of the basic features of a bicycle computer, including the average and maximum trip speeds, plus a total distance odometer.
Regen, Wh/km:There are several quantities this meter will calculate that you don't get with other instrumentation, such as the % extra range that was gained from regenerative braking, as well as the vehicle's average energy use in Watt-hours per kilometer or mile.
Peak Currents and Voltage Sag:Records the maximum forwards and regenerative currents as well as the minimum voltage on the battery pack.
Total Battery Cycles and Amp-Hours:Retains life cycle information on the vehicle's battery pack, such as how many charge and discharge cycles the pack has experienced and the total amp-hours that were delivered over its entire life.
Speed Limit:This has the utility of providing legal compliance to the speed cap imposed on ebikes in most jurisdictions. When used with a full throttle, it serves as a cruise control on the electric bicycle. It can also be beneficial to riders who want to increase their torque and power by using a higher voltage battery, without simultaneously increasing their top-end speed.
Current Limit:An adjustable amps limit is useful to prevent damage to the batteries from excessive current draw, to increase the range that you'll get on a charge, and to protect the motor controller and motor in setups that draws too many amps.
Voltage Cutout:A low voltage cutout is used to protect a battery pack from being discharged too deeply, which can cause cell reversals in NiMH/NiCad packs, permanent cell damage in Lithium packs, and sulfation in Lead Acid batteries. The programmable low voltage rollback allows you to set an appropriate low voltage point tailored to your pack.
Note:this must be ordered at time of purchase so that throttle can be customised to suit direct plug in.
