Buying a bicycle in Australia

Buying a bike, whether new from a business or second-hand from a private seller, involves more than choosing a colour. This page explains the main types of bike, sizing basics, what the national mandatory safety standard covers, what the Australian Consumer Law does and does not give you, how to reduce the risk of buying a stolen bike, how states and territories define a legal e-bike, lithium battery safety, the basic road rules, and how to avoid scams on online marketplaces, with links to official Australian sources.

The guide

From choosing a type and size, through safety standards and consumer law, to stolen-bike checks, e-bike rules, battery safety, road rules and scams.

Types of bike

Bikes are broadly grouped by where they are meant to be ridden. Road bikes are built for sealed roads; mountain bikes for unsealed trails; hybrid, commuter and city bikes sit between the two for everyday riding; and there are also folding, cargo, BMX, children's and tandem bikes. Electrically power-assisted bikes (e-bikes) exist in most of these styles and carry extra legal rules, covered below. Choosing the type that matches the riding you will actually do matters more than any single specification.

Sizing basics

Bike frames come in sizes, and a frame that is too big or too small is harder to control and less comfortable. Manufacturers publish their own size charts, and the same nominal size can differ between makers, so treat charts as a starting point only. Where you can, test ride the bike, check that you can stand over the frame comfortably and reach the brakes and handlebars without strain, and confirm the saddle and handlebars have enough adjustment for you. For children, choose a bike that fits now rather than one to "grow into".

New or second-hand

A new bike bought from a business comes with consumer guarantees under the Australian Consumer Law and, for most types of bike, must meet the national mandatory safety standard. A second-hand bike can cost less, but the mandatory standard excludes bikes with appreciable wear or that are second-hand, and if the seller is a private person rather than a business, most consumer guarantees do not apply. With any used bike, inspect it in person, check the frame, wheels, brakes, gears and chain, and confirm the bike is not stolen or subject to a recall.

The mandatory safety standard for bicycles

Product Safety Australia (the ACCC) says the bicycles mandatory standard applies to partially or fully assembled pedal bicycles with a wheelbase of 640 mm or more. It is set by Consumer Protection Notice No. 6 of 2004 and is based on sections of AS/NZS 1927:1998. Requirements include braking systems (children's bikes need at least two, one a back-pedal brake), a bell or audible warning device and reflectors on adult bikes, use and maintenance instructions, and an identification number stamped or engraved on the frame. Excluded types include e-bikes, second-hand bikes, competition, tandem, recumbent, one-off custom and most folding bikes. The ACCC is reviewing the standard: an exposure draft, the Consumer Goods (Pedal Bicycles) Safety Standard 2026, was open for consultation until 10 November 2026 and is not yet in force.

Helmets

Bicycle helmets supplied in Australia must meet the Consumer Goods (Bicycle Helmets) Safety Standard 2024. Product Safety Australia says a helmet must comply with any one of six listed standards, including AS/NZS 2063:2020 and AS/NZS 2063:2008, and must come with instructions for use, including fitting and positioning. Road rules separately require riders to wear an approved helmet; who must wear one depends on the state or territory (see Road rules). A second-hand helmet may have hidden damage, so check its history and condition carefully.

Consumer guarantees when you buy from a business

The ACCC says that when a business sells a product that does not meet the consumer guarantees, it must offer a solution: a repair, replacement or refund. For a major problem you can choose a refund or a replacement; for a minor problem the business must at least offer a free repair. These rights apply automatically, alongside any warranty. NSW Fair Trading notes that guarantees also cover second-hand products bought from businesses, taking their age and condition into account.

Private sales do not carry most guarantees

The ACCC says most consumer guarantees do not apply to one-off sales between two people where the seller is not running a business, including private sales made through online marketplaces. The only guarantees that still apply to private sales are clear title to the product, undisturbed possession, and no hidden debts or charges. Quality and fitness guarantees generally do not apply, so if a privately bought bike turns out faulty you may have no right to a refund. Product Safety Australia suggests asking whether the seller is operating as a business and checking whether the marketplace has buyer protection policies covering replacements and refunds.

Checking a used bike is not stolen

The mandatory standard requires new bikes to carry a frame identification number; Victoria Police says it is usually found on the frame near the pedals. Before you buy a used bike, ask to see the serial number, check it has not been filed off or altered, and be wary if the seller cannot explain where the bike came from or produce proof of purchase. There is no national compulsory bicycle register in Australia that could be verified for this page. Some state schemes exist: South Australia Police publish a Bike Passport for owners to record details, and the Australian Institute of Criminology describes Bikelinc, developed by Crime Stoppers WA, where police and the public can check whether a serial number is listed as stolen. If you suspect a bike is stolen, contact police (in SA, 131 444 for non-urgent matters) or Crime Stoppers on 1800 333 000.

E-bikes: what is legal depends on where you ride

Each state and territory sets its own e-bike rules, and they are changing. Common themes in the official pages checked: the rider must pedal, the motor only assists, assistance must cut out at 25 km/h, any throttle or walk-assist is limited to 6 km/h, and many states refer to the European standard EN 15194. Bikes that exceed the limits, run on throttle alone or have been "unlocked" may be treated as unregistered motor vehicles. Power limits and other rules differ: for example, NSW is moving to a lower limit with a transition to 1 March 2029, and Queensland introduced new rules from 1 July and 31 August 2026, including a minimum age and licence requirement. Check the transport department page for your state before buying, especially for a used or imported e-bike. E-bikes are excluded from the national bicycles mandatory standard.

E-bike lithium battery safety

Fire and Rescue NSW advises using only the charger supplied with the battery or one showing approval marks, charging in an open area such as a garage on a hard, non-flammable surface, not charging while asleep or away, disconnecting once full, and never using or charging a damaged battery. The ACCC also advises unplugging once fully charged and stopping use if a battery swells, leaks or vents gas. Queensland's electrical safety advice warns against buying a second-hand e-bike if the seller does not include the manufacturer-supplied charger. Never put batteries in household waste or recycling bins. In NSW, e-bikes, batteries and chargers sold must be tested, certified and carry a safety approval mark, and swapping the battery or charger changes the approved model.

Road rules for bike riders

Bicycles are vehicles under the road rules, and the details vary by state and territory. Official pages checked say riders need an approved helmet (in the Northern Territory this applies to riders 17 and under), at least one effective brake and a bell or other warning device, and at night a white front light and red rear light visible from 200 metres plus a red rear reflector. Footpath riding rules differ: in Victoria, adults must generally ride on the road, while some other states allow footpath riding. Check the transport department page for the state or territory where you ride.

Avoiding scams on online marketplaces

Scamwatch warns of fake classified ads, including sellers who say they are travelling and someone else will deliver, and items that never arrive. Be wary of prices much lower than elsewhere, pressure to pay quickly, and requests for payment by direct bank transfer, gift cards or cryptocurrency. Research the seller's history, inspect the bike in person before paying, and meet in a public place where possible. If you have been scammed, Scamwatch says to contact your bank or card provider immediately, tell the platform, and report the scam to Scamwatch.

Questions to ask before you buy

Plain questions worth putting to a seller, and checking against official sources, before you hand over money for a new or used bike.

Is the seller a business or a private person?

Consumer guarantees of quality and fitness apply when you buy from a business but generally not in a one-off private sale, including on online marketplaces.

Can I see the frame serial number, and is it intact?

New bikes must carry a frame identification number. A missing or altered number, or no explanation of where the bike came from, is a reason to walk away.

Is there proof of purchase or ownership?

A receipt or ownership record helps confirm the seller has the right to sell. Even in a private sale, you are entitled to clear title and undisturbed possession.

Has this model been recalled?

Search Product Safety Australia's recalls before buying, especially for a used bike or helmet, which the listing may not mention.

Does the bike fit me, and can I test ride it?

Check stand-over clearance, reach to the bars and brakes, and saddle adjustment. Size charts differ between makers.

For an e-bike: is it legal where I will ride it?

Ask for the motor's rated power, the assistance cut-out speed, any throttle function and whether it is labelled EN 15194, then compare with your state transport department's rules.

For an e-bike: is the original charger included, and is the battery undamaged?

Use only the supplied or approved charger, and never use or charge a battery that is swollen, cracked, dented, leaking or has been in water or fire.

How does the seller want to be paid?

Scamwatch warns about sellers who insist on up-front payment by bank transfer, gift cards or cryptocurrency. Inspect the bike in person before paying.
