“Oosten” is Dutch for “East” and hence represents the perfect blend of vintage Dutch styling combined with the latest cycling technologies from Asia. Designed from the ground up by Bikes Online Australia, where we realised that women want and deserve both style and performance from their bike.
Enormous thought went into every detail on the bike. The result is a classic vintage bike that encapsulates modern technology combined with old days’ charisma – get ready to reset what you believed a ladies vintage bike can do.
There are cheaper vintage bikes out there, there are however few better quality than the Oosten. Cheap vintage bikes are designed to last for few months before they rust, gear shifts become vague and the weight of the bike means they are simply not used any more.
When used as a commuter in all conditions and terrain, we wanted the bike to be able to still perform and hence weight became a primary concern. Where possible, alloy components are chosen – such as the frame, bars and seat post, but it is also the small details like the mud guards and brakes that result in a super light weight ladies bike.
Typical steel framed vintage bikes are both heavy and tend to flex under pressure. This is where the Oosten excels and features a 6061 Aluminium frame, resulting in a much lighter and stiffer frame. This all becomes clear when you’re faced with a steep uphill and the only way up is to stand and pedal. Where steel frame bikes flex and wobble, the Polygon Sierra Oosten keeps its composure, thus resulting in less effort spent and better ride quality.
There have been no compromises in the drive train either – rather than a 6 or 7 speed freewheel, which is a very old and difficult to service system, the Polygon Sierra Oosten features a 8 speed freehub, not only does it provide more than 30% more additional gear range but it also is much easier to service. These gears are all selected using a high quality Shimano Altus derailleur offering dependable and effortless gear shifting performance.
Confidence whilst braking has been assured with the Oosten. The latest alloy “V brakes” are used, rather than typical cantilever style. These linear pull brakes of the Oosten, offer increased power and modulation and won’t flex and grab during steep descents.
Perhaps the feature that goes inconspicuous the most in the Oosten are the wheels. Alloy double wall rims, stainless steel spokes and Alloy hubs all help in keeping the bike light but it’s the wheel size on this bike that will make the biggest difference compared to other bikes in the market. Boosting an elegant 700c set of wheels, these roll superbly on roads and bike lanes, with the added comfort almost trumping its speed.
Rounding off the bike, the rear rack, wicker basket and comfort riveted saddle ensures the bike has oodels of style and is the perfect modern take on a classic vintage bike.
