A stylish, well engineered and practical commuter bicycle. With its upright seating position and leather finishes the Zenith DX is super comfortable to ride. Combine that with maintenance free riding and you have the perfect bike for around town. The standout feature is the gates carbon belt drive, twice as durable as a chain and requires no lubricant. In addition, because it doesnt need oil/grease, it'll never get your hands or clothes dirty. Additionally the Shimano dynamo hub and front light, means you will never need to recharge or replace the batteries in the lights.
The 11 Speed Alfine rear hub, is different to the conventional rear derailleur in that it is totally encased in the rear hub. The hub is extremely low maintenance, and yet still offers a wide range of gearing. Finally, the hydraulic disc brakes complete the bike as they rarely require servicing and ensure that you have trouble free riding.

Free Pro Build valued at $99
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 here in our Australian warehouse. For your convenience, safety and comfort all our bikes are fully assembled and test ridden 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, handlebar and pedals, everything else has been done – the headset has been adjusted, wheels trued, pedals and seat post greased, brakes and gears calibrated, even the tyres have been pumped up to the correct pressure.
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. 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.

So Ive had some issues
Posted by Graham on 20th Apr 2013
In my previous review dated 18 December 2012 I was very happy with the bike since then I have had two issues which have taken the shine off for me. Both issues relate to the failure of the rear hub in early January, and again in April.
On both occasions something in the hub has failed causing a loss of drive. Pushing was the only option as the bike could not be pedaled at all.
On the first occasion I have to say that the response to my warranty claim was excellent. The bike was picked up by courier at no expense to myself with the exception of some of my time to wrap and fit the bike back into the shipping box.
The rear wheel was replaced and the bike returned to me by courier very quickly.
Unfortunately the replacement rear wheel has suffered the same fate which tends to suggest that this batch of bikes has a common fault.
Im already expecting the same level of service with my current warranty claim.
Im really dissapointed because when it is working as described it is an excellent commuter bike however two failures of an identical nature in such a short period of time, especially when I was not commuting on the bike for three months, has taken the shine off for me.
Great bike, but not for everyone

I was lucky enough to be given the Polygon Zenith bike as a birthday present. I'm a bicycle commuter who has done 5000km's a year for 10+ years around Sydney.
For commuting, this bike has many desirable features with the promise of low-maintenance and safe cycling. The bike is nice to ride with fantastic brakes, a comfy seat and good riding position. I enjoyed riding to work on this bike and found it to be very smooth with low rolling resistance and easy gear changing with the fantastic Affine hub.
However, there were a couple of things that needed attention.
1) The gearing is very tall and I found that I never needed gears 8, 9, 10 and 11, even pushing hard on the flat with no headwind. I found that 1st gear was not low enough for the (modest) hill on my commute route. I really needed about 3 gears lower than 1 to comfortably climb the hill. The only option I could find to remedy this would be to fit a smaller sprocket (39 teeth would be about right) on the front. To do this, a different length belt would be required and a four-spoke crankset as well, as the 39 tooth sprocket from Gate has four mount holes and the existing crankset has five. This would be an expensive exercise and there are alignment issues to deal with as well.
2) There is an eccentric bottom bracket mount to allow tensioning of the belt. A special tool is needed to turn the mount to allow the belt to be slackened to get the rear wheel off. If you want to do maintenance yourself (fitting new tires and repairing flats) you probably need this tool - not supplied with bike.
3) The mudgards are terrible and flop around on bumps. Because they have a flat profile they have very little longitudinal strength. Having said that, they will keep the spray off on a raining ride.
In the end this bike was not for me and I went and talked to the friendly staff at the North Manly shop. I was withing the 2 week trial period and there was no problem making a deal to order a different bike and get the balance of the payment back (thanks Joe and the guys).
Well equipped at an excellent price
Posted by Graham on 18th Dec 2012
With a dedicated road bike I was in the market for a dedicated commuter to replace my old Gary Fisher mountain bike I had been commuting on for a while. For the level of equipment I was after I really couldn't go past the Polygon Zenith Alfine 11.
I also was giving consideration to a Trek Soho Deluxe but for $200 more on road I was able to buy the Zenith which came with a much better level of equipment.
1. Hydraulic Discs vs the combination of roller brakes rear and mechanical disk front on the Soho.
2. An 11 speed Shimano Alfine hub vs the 8 speed on the Soho
3.Front suspension vs None on the Soho
4. An Alfine Dynamo Hub and Front light vs none on the Soho.
The Zenith did not come with a rack as standard however having to outlay extra for a rack did not take the shine off the attractive level of equipment for the price.
I visited the showroom to take a look first hand and I have to say that the level of customer service was generally excellent. One minor issue arose in the process which the owner Jonathan personally sorted out the next day.
Delivery was extremely close to the stated time frame. I cant fault this as I ordered the bike before the shipment had arrived in Australia and the clearance of containers from the wharves is beyond the control of any shop.
I was expecting to have to sign for the bike however arrived home to find it on my front porch.
There was some minor damage to the carton however the bike was well wrapped inside and no damage was apparent.
The bike comes partially assembled however the package includes all the tools you will need to attach the handlebars, the front wheel, front mudguard, rear reflector, bell and the front light. The website contains instructional videos on how to attach the handlebars and the front wheel but for people who have never done it before, an instructional video on how to attach the mudguard and light might be useful. The bell and rear reflector are self explanatory.
In my case the bell, an essential legal requirement, was missing from the box. A call to bicycles online easily fixed this issue and I am expecting one to be delivered in the near future. Until then I have cannibalised the bell from my old bike.
One minor quibble I have is that the website advertises that even the tyres will be pumped up to the correct pressure. In my case the rear was flat and the front was well below pressure. Both were easily fixed however this could have been an annoyance for someone who relies on the local service station to fill their tyres.
Riding the bike the first thing you notice is how quiet the drive line is. The belt drive combined with the Alfine hub makes for an almost silent ride with the exception of 7th gear. When you are in 7th and pedalling the rear hub makes a noise similar to a standard free wheel. This noise is not obtrusive and does not detract from the experience.
Shifting gears is smooth and easy once you work out that it is better to stop pedalling when you shift. Shifting with the power on makes for clunky shifts.
Switching on the front light gives you an acceptable level of light with very little noticeable drag from the dynamo hub. The only real disappointment with the front light is the lack of a stand light. When you stop the light goes out. A small blinking LED front light is my recommendation for the safety conscious to mark your position when stationary.
I find the saddle very comfortable and the hydraulic disc brakes work very well.
Moving over from a mountain bike I noticed the difference in ground clearance
If weight is an issue for you this may not be the bike for you. Hub gears, dynamo hubs, mudguards and racks all add weight. It is not something you notice when riding the bike and for me the extra weight did not make hill climbing any more difficult.
The very low maintenance combination of belt drive and hub gears comes with a penalty in that there is no rear wheel quick release. This is not a bike from which you can easily remove both wheels to fit it in the car.
I have only owned the bike a short time however have noted that one of the Allen key head bolts which holds on the rear mudguard has vibrated loose. Fixing this means removing the rear wheel as there is insufficient clearance between the tyre and the guard to fit an Allen key in. This is somewhat of an annoyance and could be prevented by using loctite on the threads during assembly.
Fitting the rear rack also lead to a very annoying rattle between it and the rear mudguard on anything other than perfectly smooth road. A small piece of closed cell foam between the rack and the guard appears to have fixed this problem.
Overall only a few minor things prevent this from being a five star bike outright but in the value for money stakes it is hard to beat. For those in the market for a well equipped commuter this bike is definitely worth a look.
