Polygon Siskiu D6

Completely defective on all levels – Firstly it took over 10 days to arrive. I had to chase this up after 5 days when it said it was delivered yet hadn’t been dispatched yet. Upon arrival, packaging was notably very good and transported well. Putting this bike together was easy as this is my second purchase from bicycles online. After assembling, the problems began. Brakes very spongy and full travel will not lock. Rear shock had no air. Gears randomly change without input from lever. Finally was able to get enough air into rear shock to ride it. Lasts several hours then shock has lost all air. Today, rear axle completely worked its way loose on the trail and rear wheel twisted sideways and gouged inside of frame. Had to walk 2km back to my car to get tools to fix.

Have notified bicycles online and as I’m inside the 14 days free returns I have requested a complete refund all the while they insist I take bike to a bike shop to repair that has a three week lead time.

Do not buy from bicycles online unless your prepared ti be stuffed around and deceived

Fantastic bike for the price – Awesome mountain bike great build great ride. This was my first online bike purchase and I couldn't be more happy, prompt delivery as well. I had a ball putting it together and setting it up to how I want it. I had looked at several duel suspension bikes but nothing for the money I had. I have a done a couple of upgrades pedals and grips.

Harder than a coffin nail – Love this bike. Had it 5 months, ride it x4 per week. Love how it handles even on slippery terrain. I thrash it through the Kuitpo Forrest in SA most weekends and it's well up to the task. It fell off the back of the car at 110 kph and survived with only scrapes etc. Only thing I've noticed is the gears can sometimes fail to change without a second nudge of the lever which can be a distraction. Other than that totally love it. Will be getting a dropper post for it soon.

Awesome Bang for your Buck – Really excellent value. Solid frame with good welds. Front fork needs spacer removed to gain full 120mm of travel. This also makes travel more progressive. Parts list should make this bike much more expensive. Bike has held up to some solid hits. Needs a chainstay protector to shield frame. Would highly recommend people to try out Polygon.
