Probably not. Nearly half of Greater Sydney households run two or more cars, yet the second car is almost always the one doing short, local trips — the school run, the grocery dash, the station drop-off. Those are exactly the journeys a modern e-bike does more cheaply, faster through traffic, and without a $200-a-week running bill. If you’re rethinking whether you really need a second car in Sydney, the maths is increasingly on the side of two wheels.
How many Sydney households actually run two cars?
A lot of them. According to the 2021 Census, 31% of Greater Sydney households own two cars and another 15% own three or more — so close to half the city keeps at least a spare vehicle on the driveway (City of Sydney / ABS car-ownership data). Nationally, the average is about 1.8 vehicles per household.
Here’s the catch: the second car is usually the “just-in-case” car. It sits parked most of the week and comes out for quick errands measured in single-digit kilometres. You’re paying for a two-tonne machine to do a job a bicycle could handle. That’s the core of why Sydney became so car-dependent — and how e-bikes can start to fix it: we bought more cars to solve problems more cars created.
What does that second car really cost you?
Far more than the fuel. The RACV’s annual running-costs research puts even a light or small car at roughly $850–$950 a month — around $200 a week once you add registration, CTP, insurance, servicing, tyres, depreciation and fuel (RACV car running costs). Those fixed costs don’t care how little you drive — a barely-used second car still bleeds money every single week.
Zoom out and the picture is worse. The Australian Automobile Association’s Transport Affordability Index — which models a typical two-car household — found transport swallows about 15.8% of household income, and Sydney carries the highest absolute transport costs of any Australian capital. If you want the full breakdown, we’ve already crunched how much owning a car really costs in Sydney. Retiring the second car is one of the biggest single line-items a Sydney family can cut.
Can an e-bike really replace a second car?
For the second car’s trip profile — short, frequent, local — yes. In NSW you can ride a pedal-assist e-bike up to 250W with assistance cutting out at 25 km/h, with no licence, registration or insurance required. That covers the vast majority of second-car journeys without a cent of ongoing rego or CTP.
The practical question is whether one bike can carry the load, and this is where a purpose-built commuter earns its keep. The Cyberbikes Centauro runs a 250W rear hub motor and a 48V 25Ah (1,200Wh) Samsung, UL 2271-certified battery, with a rear cargo rack welded to the frame and rated to 50kg and a total rider-plus-cargo limit of 150kg. Full suspension and hydraulic brakes mean a week of groceries, two school bags or a laptop commute are all well within its remit. And on Sydney’s congested inner-west streets, a bike frequently beats a car door-to-door on trips under about 5km — then parks for free.
What would Sydney gain if households dropped the second car?
Everything that a car-lighter city gains, multiplied across a million driveways. Short car trips are the easiest journeys to shift, and every second car retired frees a parking space, a slice of road capacity and a chunk of transport emissions. Fewer idle vehicles competing for kerb space is exactly the kind of mode shift that has let cities like Paris and Amsterdam claw back their streets. Sydney doesn’t need every household to go fully car-free tomorrow — it just needs a lot of us to question the second car.
Frequently Asked Questions
Is it legal to ride an e-bike instead of driving in NSW?
Yes. In NSW a pedal-assist e-bike rated up to 250W, with the motor cutting out at 25 km/h, is treated like a normal bicycle — no licence, registration or insurance needed. That’s a large share of typical second-car trips covered with zero ongoing government charges.
Can an e-bike carry kids or groceries like a second car?
A cargo-capable commuter can. The Cyberbikes Centauro has a frame-welded rear rack rated to 50kg, a 150kg total rider-plus-load limit and an optional front basket, so a big grocery shop or a school run is well within reach.
How much can I save swapping a second car for an e-bike?
A second car costs roughly $200 a week to run (RACV). A Centauro is $3,999.99 outright, or from $99.99 a week on rent-to-own — and at the end it’s yours to keep, with no rego, CTP or fuel bills.
Curious what going car-lighter would look like for you? Swap one car trip a week for an e-bike ride and see what changes — then come talk it through with us at Cyberbikes, 281 Parramatta Road, Leichhardt. The Centauro is a good place to start, from $99.99/week rent-to-own.
