The Marin Fairfax SC4 Belt Drive city bike is the height of low maintenance, efficient, urban transportation.

With a combination of sophisticated tube profiles the series 3 aluminium frame and fork give the bike a refined presence. The utility of the bike has not been forgotten during the design process with the Marin Fairfax frame featuring plenty of rack and fender mounts, both front and rear, so your options to haul everything from your laptop to a change of clothes, are unlimited.

A smooth and reliable Gates Carbon belt drive is grease-free  and pants friendly, and won't wear out like a normal chain, whilst the highly engineered internal Shimano Nexus 8-speed gear hub gives you plenty gears to navigate city streets, and with much less maintenance than typical drivetrains, itll spend less time in the shop too.

Powerful, easily modulated hydraulic disc brakes give you all-weather stopping power that makes navigating traffic a breeze.

A set of Marin aluminium double wall rims are durable and can stand up to even the worst city streets and potholes, while Schwalbe Road Cruiser 700x32 tyres with puncture protection give you a cushy and comfortable ride and keep punctures to a minimum.



Your bike will arrive in a custom Bicycles Online bike guard box as described in the below video.

Just make sure you keep the box so it can be re-used to send it back. Click here for more information. 

All of our bicycles come with a Free Pro Build valued at $99. This means that your bicycle will be pre built by our professional mechanics. For your convenience, safety and comfort all our bikes are fully assembled prior to delivery. The bike is then packaged back into a box for secure shipment.


When your bike arrives, all you have to attach is the front wheel, the handlebar and pedals, everything else has been done – the headset has been adjusted, wheels trued, pedals and seat post greased, brakes and gears calibrated, and the tyres have been pumped up (please note upon arrival, in some cases you may need to add more air to tyres).

Most companies simply sell you the bike as it comes from the factory, which will require significant know-how to get your bike on the road. Currently we are the only Australian company providing this service, and have the 14 day test ride to back it up.

All tools are provided with the bike.

If you are unsure of how to assemble this bike after viewing the instruction videos above, we recommend you ask for help from someone with knowledge of how to use basic hand tools.
