Love your bike.
Make it electric.
An honest guide to e-bike conversion kits — what they cost, when they're worth it, and why mid-drive is the only answer if you're serious about it.
Let's get one thing out of the way. You're not here because you want a cheap e-bike. You're here because you've got a bike you love; there's just something about the geometry, the ride, the way it fits you like a well-worn jacket — and you're wondering if you can make it electric without losing everything that makes it yours.
A great question. Let's talk about it.
In case you haven't looked outside in the last four years, E-bikes are everywhere now. And for good reason. The factory options have come a long way — solid commuter builds, clean integration, ready to ride out the door. For a lot of people, that's exactly what they need. But for some riders, the bike they already own is the bike they want to keep riding. They just want it to do more.
A conversion kit gives you something different: flexibility, custom performance, and the ability to ride the bike you already know and trust. A factory e-bike gives you integration and simplicity. Neither is wrong. But they solve different problems.
One thing worth knowing early: at Melbourne Powered, we specialise in high-quality mid-drive conversions — not cheap rear hub kits from the internet. This article is about doing it properly. If you're after a $300 plug-and-pray kit, this isn't the article for you.
Why Are E-Bike Conversions Worth It?
It starts with a simple question: Is the bike you've got worth making better?
Not every rider wants to buy a new e-bike off the floor. Some have spent years finding a bike that fits them perfectly. Others want more grunt than a stock factory system can deliver. And some just want a setup that's theirs — not the same build everyone else is riding.
A quality conversion gives you:
- Full customisation: Choose your motor, battery size, voltage, and display to suit your riding style and terrain.
- More power than entry-level factory bikes: High-quality mid-drive systems can outperform many factory e-bikes in the $2,000–$3,000 range.
- An upgrade path: Battery capacity, controllers, and components can be improved over time.
- A bike you already love: Fit, geometry, and feel don't change.
But remember, although e-bike conversion kits are great for certain bikes and scenarios, not every bike is worth upgrading. Here are the pros and cons:
Pros
- Full customisation (motor, battery size, voltage).
- Often more powerful than entry-level factory bikes.
- Can outperform mid-range factory systems.
- A valid upgrade path over time.
- Keeps a bike you already love (maybe you'll love it even more!)
Cons
- Higher upfront cost if done properly.
- Requires a compatible donor bike.
- More technical complexity.
- Not all frames are suitable.
- Warranty structure differs from factory bikes.
A quick note on 'budget' conversion kits:
- Yes, they exist. No, they are not worth it.
- They use generic, often poorly designed rear-hub motors
- They have very limited tuning potential
- They are unreliable and lead to range anxiety
- They often lack local support.
To put it plainly, we know that it's tempting to go with a budget option. Dip your toe in, etc. But trust us, they still take a lot of effort to install, and the end result is rarely worth the time. All they usually accomplish is turning great bikes into rubbish e-bikes.
Can I convert it myself?
The short answer is yes – if you have the time, the tools, the workshop, and the will-power to accept that if it messes up, there's no one responsible but yourself. Most people tend to have one or two of those attributes, but rarely all four.
Expertise required to convert an e-bike
At a base level, if you want to convert an e-bike yourself, we'd say you need to make the following considerations:
- Do you have a decent bank of mechanical knowledge?
- Do you know what your bike's bottom bracket is compatible with?
- How will you approach cable routing?
- Are you comfortable with safely mounting the battery?
- Do you understand controller tuning?
Unfortunately, no e-bike conversion is as simple as bolt-on and ride away – especially with mid-drives.
When professional installation makes sense
If you answered no to more than one of the above questions, getting a professional installation makes sense for you. A professional set up doesn't just get you 'peace of mind', it also ensures:
- Correct torque settings on all components
- Safe battery placement and setup
- Proper controller configuration
- Reduced drivetrain wear
- A fully compliant e-bike
But best of all, professional installation means that you'll have your bike successfully converted in days, not weeks or months.
Mid-Drive vs Rear Hub Conversion Kits
The question of whether to go with a mid-drive or rear-hub conversion kit is an important one. We have to admit that both have their strengths, but if you're really serious about your e-bike conversion, we're quite sure that there's only one winner.
Mid-Drive (What We Recommend)
- Drives through the drivetrain itself
- Better torque for climbing hills
- More efficient under load and with cargo
- Significantly better for weight distribution
- Feels much more natural to ride
Rear Hub Kits
- Generally cheaper
- A simpler, more DIY-friendly installation
- Less torque efficient
- Often suffers from lag, feeling disconnected from pedal input.
If your goal is a proper, long-term e-bike upgrade, mid-drive is definitely the way to go.
How Much Does a Conversion Cost Vs Purchasing a New E-bike?
At some point, we all have to consider cost. So in this section, we'll break down the difference between the two.
A Rough Price Comparison
The tl;dr for this section is that conversion is not the cheap option. It's the option you choose when you really love your ride.
For example, a quality mid-drive conversion will typically set you back around $3,500 AUD. That generally includes installation, but the number depends on:
- Motor choice
- Battery size
- Display choice
- Installation complexity
By contrast, you can buy a very decent commuter e-bike for around $2,000.
Simply put, if your goal is the most affordable way into e-biking, buy a factory e-bike. If your goal is the right performance upgrade for a bike you love, consider conversion.
Conversion vs Buying a New E-Bike
| Conversion | Factory E-Bike |
|---|---|
| Customisable | Integrated |
| Higher performance potential | Clean aesthetics |
| Upgradeable | Protected by warranty |
| Requires a compatible donor bike | Ready to go out of the box |
When Is a Conversion Worth It?
So when should you pull the trigger on a conversion? Well to clear any confusion, let's break it right down.
Conversions are worth it when:
Conversions are NOT worth it when:
- You own a high-quality bike
- You want more torque than entry-level e-bikes can offer
- You ride hills, carry cargo, or commute longer distances.
- You want tuning flexibility.
- You value performance over "plug and play".
- Your budget is tight.
- Your base bike is of low quality.
- You want zero technical involvement.
- You want simple warranty coverage.
That's really the long and short of it. If based on nothing else, you should make your decision based on whichever of those two lists most describes you and your situation.
