The new Polygon Entiat E is a rugged pedal assist trail bike that's ready to take you on off-road adventures you never thought were possible. 

The Entiat E utilises Shimano's STEPS E8020 proven performance motor. It is optimised for off road use with more torque to help you climb steeper, technical hills. The Bluetooth compact display is easy to use without needing to let go of the handlebar. Personalize your assist mode settings by choosing Dynamic, Explorer or Custom to perfectly match your riding style and intended terrain. Many brands now use the Shimano E8020 system, however, Polygon has integrated the 504 watt-hour battery into the down tube maintaining the sleek looks of a traditional mountain bike, whilst making it easy to disconnect for charging.

The Entiat E is built around Polygon's trail ready ALX Boost alloy frame, an efficient aluminium design that combines durability and performance with the new BOOST system (hub system originally developed by SRAM - 12x148mm rear, 15x110mm front). With wider Boost hub flanges, it allows the spokes on the wheelset to make a wider triangle which results in more support for the rim and a stronger overall wheel. Compared to a regular hardtail mountain bike which is normally designed for XC riding, the slacker head angle (66.5 degrees) combined with the shorter chainstays allow the bike to be ridden in more vertical environments. Along with the inherent cushion of the oversized wheels and tyres, a Rockshox Recon Silver front suspension fork with 120mm of travel and hydraulic lockout helps soak up the bumps.

The Entiat E groupset combines a 1 x 11 Shimano Deore XT drivetrain with a Shimano XT Crankset running a Narrow-Wide 32T chainring. Shifting is supported with Shimano XT triggers and Shimano's M6000 hydraulic disc brakes take care of the stopping power providing excellent modulation in all conditions.  The Entiat E rolls on a set of Entity Boost 27.5+ wheels wrapped in Schwalbe Nobby Nic 27.5" x 3.0" tyres.

The Entiat E is finished with Entity Xpert stem, saddle, and handlebar, all of which balance weight savings with the kind of durability mountain biking demands. When all is said and done, this is a fun bike. Whether you are a newcomer to mountain biking or an experienced rider looking to get more out of your ride, the Entiat E can ride faster with more control, climb steeper sections with better traction and negotiate trickier descents with more forgiveness. This is one bike to do it all and will reliably shepard you on mountain bike adventures for many years to come.

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.

Please note, that all bicycles whether purchased online or instore, are mechanical devices and need to be serviced regularly to ensure proper functioning. New gear and brake cables, will stretch during the initial bed-in period, and will need to be adjusted after approximately 150-300km.
