Everything You Need in a Complete Ebike Conversion Kit with Battery
Let's be real, we all love our bikes. That mountain bike caked in mud from more trails than your hiking boots, or the hybrid for the daily grind. You know it inside out. But headwinds on the ride home and those brutal Dandenong hills? They're not getting any easier.
Here in 2026, you don't need to drop five grand on some shiny new e-bike to get that extra shove. A complete ebike conversion kit with battery lets you keep the frame you love and just bolt on some proper power.
But with all the ropey kits floating around online, how do you know which ebike motor kit with battery won't leave you stranded? This guide cuts through the noise on DIY electric bike conversion so you can make the switch to electric with your eyes open.
1. Why Choose a Complete Ebike Conversion System?
The biggest mistake many Aussie riders make is buying their motor and battery separately from different overseas sellers. It sounds like a bargain until the connectors don't match, or the controller can’t handle the battery voltage.
Choosing a complete ebike conversion system ensures:
-
Plug-and-Play Compatibility: No soldering or "dodgy" wiring required.
-
Optimised Performance: The motor and battery are tuned to work together for maximum range.
-
Simplified Support: One point of contact if you have a question (and at Rev-Bikes, we actually answer the phone).
2. Mid-Drive vs. Hub Motor: Which Kit is Right for You?
When you are about to buy an electric bike battery and motor kit, one of the most important things to account for is the motor's location.
Mid-Drive Kits (The Hill Climber’s Choice)
Mid-drive motors, like our popular Bafang and Tongsheng units, sit right at your bike crank (where the pedals are).
-
Pros: They use your bike’s existing gear. This means you can shift down for a massive torque boost on steep hills.
-
The Feel: It feels like a natural extension of your own strength.
-
Best For: Mountain bikers and anyone living in hilly suburbs.
Hub Motor Kits (The Commuter’s Choice)
These motors are integrated into the front or rear wheel and are the most powerful option.
-
Pros: Generally, more cost-effective and less complicated to install. If you just want a reliable "push" to get to work without breaking a sweat, a rear hub ebike motor kit with battery is a cracker of a choice.
-
The Feel: More like being "pushed" or "pulled" along.
-
Best For: Flat commutes and city riding.
3. The Power Source: Choosing Your Electric Bike Battery
A battery is the "fuel tank" of your electric setup. If you are buying an ebike conversion kit with battery, you have to consider two major numbers: Volts (V) and Amp Hours (Ah).
-
36V vs 48V/52V: Most street-legal kits in Australia are operating on 36V or 48V. Higher voltage generally means more "grunt" and efficiency under load.
-
Amp Hours (Ah) = Range: Think of Ah as the size of the petrol tank. A 10Ah battery might get you 30-40km, while a 17.5Ah "Maxi" battery can push you well past 60km depending on how much you’re pedalling.
Pro Tip: Not all lithium cells are created equally. At Rev-Bikes, we only use the best quality cells (like Samsung or Panasonic) because they have a long lifespan, charge safely, and won’t leave you in the middle of the hill.
4. Is a DIY Electric Bike Conversion Legal in Australia?
We receive this question very frequently. To be "street legal" on public roads and bike paths of most of Australia, your converted bike must possess the following characteristics:
-
Motor Power: Continual maximum power rating of 250W (or 200W for throttle-only systems) is the limit for motor power.
-
Pedal Assist: The motor should not assist unless you are pedaling (Pedelec).
-
Speed Cap: When you get to 25 km/h, the motor will stop assisting anymore.
Note: We do stock higher-powered kits (like 1000W or 1500W systems), but these are strictly for off-road use or private property. Always check your local state regulations!
5. What’s Actually Inside the Box?
When we say "complete," we mean it. A quality complete ebike conversion system should include:
-
The Motor: (Hub or Mid-Drive)
-
The Battery: Usually with a mounting cradle and keys.
-
The Controller: The "brain" that manages the power.
-
LCD Display: To track your speed, battery level, and assist mode.
-
Pedal Assist Sensor (PAS): For indicating the motor your pedalling activity.
-
Brake Sensors: For interrupting the motor instantly upon braking action.
6. How Hard is the Installation?
Doing a DIY electric bike conversion doesn’t need to be a rocket science task. If you can change the wheel and handle a simple Allen key, then you are almost there.
-
Hub Kits: Usually it takes about 1–2 hours.
-
Mid-Drive Kits: A bit more involved (you’ll need to remove your bottom bracket), usually taking 2–4 hours.
If you’re not confident getting your hands greasy, many local bike shops can help, or you can drop into our Melbourne workshop for a professional fit-out.
