Best Electric Bike Conversion Kits with Battery in Australia
G’day, riders! When your old bike had been lying in the shed, or your daily journey was beginning to feel like a grind when you hit those hills, you must have noticed that the price of a new e-bike is beginning to climb. Prices of some of the best models are more than 5000 dollars! That is why many Australians are taking a smarter option, the electric bike conversion kit that has a battery.
We are ten years old and at Rev-Bikes we have been assisting people refurbish their bikes. It is not unusual that your current bike is the best one. With a great conversion kit, you not only save money; you also have a bike that has been ridden the way you desired it would, and it also looks perfect in your style.
This guide will take you through all you need to know when choosing the right electric bike conversion kit with battery in Australia. Whether it’s the variety of types of motors as well as the size of them, or the most recent legal regulations of 2026, we will simplify it so that you can get the kit that suits your city’s commute, weekend activities, or off-road fun.
Why Convert? The Case for the "RevAmped" Ride
Why would you choose a bicycle conversion kit electric setup over a shiny new factory e-bike? Besides the self-evident cool aspect of a DIY project, it contains three solid justifications:
-
Unbeatable Value: You can purchase a mid-drive system of the highest quality and a high-capacity Samsung battery at about half the price of a similar retail e-bike.
-
Sustainability: Australia generates quite a lot of wastes. By recycling your old frame, you not only save high-quality steel and aluminium into the landfill, but also you have cut the carbon footprint of making an entire new bike.
-
Customisation: Majority of factory e-bikes are either it or nothing. Using a kit, you select the power of the motor, the size of the battery (range of the distance), and display style.
Choosing Your Motor: Hub Motors vs. Mid-Drives
As you begin to search through an e-bike motor kit, you will discover two major competitors. It all will depend on the location of the place you live and the usage of the bike.
1. Hub Motor Conversion Kits: The Reliable Workhorse
A hub motor conversion kit replaces one of your wheels with a motorised version. These are incredibly popular for city commuting because they are simple, quiet, and mechanically independent of your bike's gears.
-
Front Wheel Electric Kit: These are the easiest to install. They provide a "pulling" sensation and are great for balanced weight distribution if your battery is mounted on a rear rack.
-
Rear Wheel Electric Kit: These offer better traction, especially on gravel or wet bitumen. They feel more like a traditional bike "pushing" you along.
Best For: Flat to moderately hilly terrain (think Melbourne Bayside or Perth’s cycle paths) and riders who want a low-maintenance "set and forget" system.
2. Mid-Drive Conversion Kit: The Hill Slayer
A mid-drive conversion kit (like the world-renowned Bafang or the Italian-made Bikee Bike) mounts at your bike's crank. Because it drives the chain, it can leverage your bike's existing gears.
-
Torque & Efficiency: Just like a 4WD in low range, a mid-drive can shift into a low gear for a 15% gradient hill and then shift up for a 40km/h sprint on the flat.
-
Balance: The motor is low and central, which keeps the bike’s centre of gravity perfect for mountain biking or agile city weaving.
Best For: Hilly suburbs (Sydney’s North Shore, the Adelaide Hills, or Brisbane’s steep pockets) and anyone looking for the most natural "bicycle" feel.
The Fuel Tank: Choosing an Electric Bike Battery
The most common mistake we see is people buying a powerful motor but pairing it with a "no-name" battery from a generic marketplace. In the Australian heat, those batteries can sag, lose capacity, or worse, become a safety hazard.
When you buy a bicycle conversion kit electric setup from Rev-Bikes, we only use premium cells (Samsung or Panasonic). Here’s a quick breakdown of how to choose your "fuel tank":
|
Battery Option |
Capacity (Wh) |
Estimated Range (PAS) |
Ideal Use Case |
|
The Commuter |
~360Wh |
30km – 45km |
Short daily hops to the train station. |
|
The Explorer |
~540Wh |
50km – 70km |
The "Goldilocks" size for weekend rides. |
|
The Tourer |
~720Wh |
80km – 100km |
Long-distance trekking and heavy loads. |
|
The Professional |
1000Wh+ |
120km+ |
Delivery riders and touring the Outback. |
Pro Tip: Always look at Watt-hours (Wh), not just Volts. To find Wh, multiply Voltage by Amp-hours ($V \times Ah = Wh$). This is the true measure of your "fuel tank" size.
Staying Legal: Australian E-Bike Laws in 2026
The law has tightened up recently, and for good reason. To be able to ride your converted bike on the public roads, bike paths, and shared trails in Australia, your kit will be required to comply with the following requirements:
-
250W Limit: There must be a maximum constant rated power of 250 Watts in the motor.
-
Pedal Assist (Pedelec): When you are pedalling the motor should not work.
-
Cut-off 25km/h: The electrical aid should be terminated when you attain 25km/h.
-
Throttle Rules: A throttle is legal only if it cuts out at 6 km/h (to help you start) or only functions while you are pedalling.
Note on High-Power Kits: We do sell 750W and 1000W kits (like the Bafang BBSHD), but these are strictly for private property use only. If you’re riding to work in Sydney or Melbourne, stick to the 250W legal limit to avoid hefty fines or potential bike seizure.
Installation: Can You Do It Yourself?
"Will I need a degree in engineering to fit this?" The short answer is no. Most of our electric bike conversion kit with battery packages are designed for the DIY enthusiast.
-
Hub Kits: If you can change a flat tyre, you can install a hub kit. You’re essentially just swapping a wheel and plugging in a few colour-coded cables.
-
Mid-Drive Kits: You’ll need a couple of special tools (like a crank puller and a bottom bracket tool) to remove your existing pedals. It takes most people a Saturday afternoon and a couple of cold ones to get the job done.
Not a "wrench" person? No dramas. We have a grouping of associate stores and have our own workshop in Nunawading VIC where we will install the kit professionally to you.
Frequently Asked Questions (FAQ)
1. Will a kit fit my specific bike?
Most "standard" bikes are compatible. The only thing you must do is to check your wheel size (26-inch, 27.5-inch, 29 inch, or 700c) and make sure you have some space in the frame to fit the battery. We offer information about what best fits your bike so if you are not sure, send us a picture of your bike and we will tell you what fits!
2. What is the distinction between 36V and 48V?
Imagine it as a 4-cylinder or 6-cylinder vehicle. The 36V model is portable and ideal for urban commuting. A 48V system has greater torque and punch and is preferred by heavy riders or extremely hilly terrain.
3. How long does it take to charge?
Between 3 and 6 hours depending on the charger and size of battery. Most of our riders would just plug it overnight as in the case of a mobile phone.
4. Are conversion kits safe in the rain?
absolutely. Our kits use waterproof (IP65) connectors. While we don’t recommend taking your bike for a swim in the Yarra, riding through a typical Aussie downpour won’t bother the electronics at all.
