Unboxing the Polygon Siskiu T6E e-bike

Polygon Bikes are known to deliver some incredible value, and the bikes we have tested from Polygon sure shows that rings true. From the recent Polygon Colossus N8E eMTB, or of course a Polygon Siskiu D6, the value is there at just about any price point. Polygon Bikes are sold exclusively via Bikes Online who are, you guessed it, an online bike shop.

We've just had a Polygon Siskiu T6E all-mountain e-bike ($5499) turn up for testing. Like all bikes from Bikes Online, these come delivered by a courier company, after you have made your purchase online. This does mean you need to know what bike you want, and what size. But the Bikes Online website is really thorough, and the customer support at HQ in Sydney is top class. There's even 14 day free returns if the bike just isn't for you.

The Siskiu T6E is a 29er full-suspension bike with 150/140mm travel front and rear respectively. Suspension is taken care of by a Suntour Zeron 35 fork and an Edge Plus RC rear shock. Both have an air spring for easy adjustment, plus rebound damping. There's room below the shock for a small water bottle, and within the link there are two shock mounts; one for running a 29" rear wheel (as stock) and one to adjust the geometry for a mullet setup (27.5" rear wheel)

Shimano take care of the drivetrain with a wide range Shimano Deore group set. It's got a clutch for chain security and you can see the Polygon has some excellent frame protection to help with a quiet ride. The tyres are Schwalbe Hans Dampf with a strong Super Trail casing. 

While wheels and tyres can be a weak point on some eMTBs, that doesn't look to be the case with the Polygon Siskiu T6E. Another area that needs proper spec is brakes, and Polygon have looked to the SRAM stable for their Code R 4-piston brakes, with 203mm rotors on both ends. 

Shimano's EP6 e-bike system has 85Nm of torque and an average 250W of power across the life of the 504Wh battery. The mode selector sits neatly on the left side above the grip. It's easy to toggle and a dropper lever sits nicely with the brakes and mode selector.

The bike came together very quickly and easily, and Bikes Online include a torque wrench and pedal wrench, plus pedals, so you can get riding. There are instructions included if you're a bit stuck. I fitted my own SPD pedals. With pedals the bike clocked 24.78kg (size large) on my scales.

For $5499, this is a lot of e-bike from Polygon. It has a solid wheel and tyre spec, powerful brakes strong drivetrain and reliable eMTB system. 

This is the first time I will have ridden these two Suntour suspension items, and the Shimano EP6 system. But overall, the spec sheet looks like it has been thoroughly thought about to deliver a quality ride at a sharp price.

Our large test bike has a 485mm reach and short 105mm head tube. With a 65 degree head angle and steep 77 degree seat angle the geometry is dialled, and should encourage a very balanced position on the climbs and descents. You can get the T6E in small, medium, large and extra large.

For now, it is time to get the suspension setup and get it on the dirt. Stay tuned for a full review once I've had enough time on it – subscribe to our YouTube channel so you don't miss it. Or, subscribe to our magazine so you get lots of reviews and mountain bike stoke delivered to your door.
