Walk into any e-bike shop and you’ll hear two terms thrown around constantly: mid-drive and hub-drive. Both get you moving, but they do it in very different ways — and the difference matters more than most people realise when you’re deciding which e-bike to buy.
Here’s a straight-talking breakdown of how each motor type works, who each one suits, and what we recommend at Cyberbikes Leichhardt.
The short answer: a mid-drive motor is the better choice for hills, efficiency and a natural pedalling feel, while a hub-drive motor is the better choice for flat commuting on a smaller budget. A mid-drive sends power through the bike’s own gears, so it multiplies torque as you shift down on a climb. A hub motor drives the wheel directly at a fixed ratio, so it works hardest exactly when the gradient is steepest — which is why hub motors run hotter and drain more battery on hilly routes.
What Is a Hub-Drive Motor?
A hub-drive motor sits inside the wheel hub — either the front or rear. When you engage the assist, the motor directly drives the wheel. It’s a simple, proven design that’s been around since the early days of e-bikes.
Pros of hub-drive:
- Lower upfront cost — fewer moving parts means cheaper to manufacture
- Low maintenance — the drivetrain (chain, cassette, derailleur) runs independently, so motor wear doesn’t affect gears
- Quiet operation — most hub motors are smooth and unobtrusive
- Regenerative braking on some models (not common in Australia yet)
Cons of hub-drive:
- Less efficient on hills — the motor works at a fixed mechanical advantage regardless of terrain
- Can feel “pushy” or unnatural — it’s propelling the wheel directly rather than working with your pedalling
- Heavier wheel — harder to remove for puncture repairs
- Less natural riding feel, especially at low speeds
Hub-drives shine for flat terrain, casual riding, and budget-conscious buyers. If most of your riding is along Sydney’s harbour foreshore, flat commutes, or beach paths — a good hub-drive e-bike does the job well.
What Is a Mid-Drive Motor?
A mid-drive motor sits at the centre of the bike — at the bottom bracket, where the pedals attach. Instead of driving the wheel directly, it drives the chain, which means it works through your bike’s existing gears.
This is the key difference — and why mid-drive motors are generally considered the superior choice for performance and versatility.
Pros of mid-drive:
- Works through the gears — so you’re always in the optimal mechanical advantage for the terrain
- Better hill climbing — exponentially more efficient on inclines like those around Sydney’s inner west
- More natural riding feel — the motor amplifies your pedalling rather than replacing it
- Better weight distribution — centralised motor keeps the bike balanced and nimble
- Pairs well with torque sensors for ultra-responsive, natural assist
Cons of mid-drive:
- Higher upfront cost — more complex technology
- More drivetrain wear — the motor puts extra stress on your chain and cassette (especially if you’re riding hard)
- Service can be more specialised
Which One Is Right for You?
The honest answer depends on where and how you ride.
If you’re doing flat urban commuting — think Newtown to the CBD, Leichhardt along Parramatta Road, or Bondi to Randwick — a hub-drive will serve you well and save you money upfront. The terrain doesn’t demand more.
But if you’re riding in hilly terrain (hello, inner west and northern suburbs), doing longer distances, want a more natural, sporty feel, or plan to do any trail riding — a mid-drive motor is worth every extra dollar.
The Cyberbikes Centauro uses a high-torque mid-drive motor paired with a torque sensor — meaning it reads how hard you’re pedalling and scales the assist accordingly. The result? A ride that feels completely natural, not like a moped. You get genuine exercise benefits while still arriving at work sweat-free. On Sydney’s rolling streets, the difference is night and day.
The Bottom Line
Hub-drive: affordable, reliable, great for flat terrain.
Mid-drive: superior performance, better hills, more natural feel — the choice of serious riders and daily commuters who want their e-bike to last.
When you’re spending $2,000–$5,000+ on an e-bike, getting the motor right matters. Come and test ride both at Cyberbikes, 281 Parramatta Road, Leichhardt — we’ll put you on the right bike for your actual riding conditions, not just the most popular model. Open Tuesday to Saturday.

Mid-drive vs hub-drive: frequently asked questions
Is a mid-drive or hub motor better on an e-bike?
For most Sydney riders a mid-drive motor is better, because it works through the gears and keeps the motor in its efficient range on climbs. A hub motor is better if your route is mostly flat, you want the lowest purchase price, and you value a simpler drivetrain with less chain and cassette wear.
Where can I test ride a mid-drive electric bike near Randwick?
You can test ride mid-drive and hub-drive e-bikes side by side at Cyberbikes, 281 Parramatta Road, Leichhardt — an easy trip across the inner west from Randwick and Sydney’s eastern suburbs. We are open Tuesday to Saturday, and riding both motor types back to back on the same hill is the fastest way to feel the difference.
Do mid-drive e-bikes cost more to maintain?
Usually a little more. Because a mid-drive pushes its power through the chain and cassette, those parts wear faster than on a hub-drive bike and are replaced more often. The trade-off is that the motor itself runs cooler and works less hard, and drivetrain parts are cheap compared with a motor or battery.
