Battery – Lithium Ion (EU Certified) frame mounted *


eZee Kinetic has just released the new E-Rex fat tyre bike.  It is equipped with the latest V3 Kintic motor that just won the 7000km Sun Trip ebike race, beating the Bosch equipped competitors by two days! Our Erex has just gone across the Outback ridden by a chap with a solar trailer carrying all camping gear and power assist to the ebike. E-Rex. See http://ezeebike.com/crossing-great-australia-desert-ezee-e-rex-solar-energy/ for a report on this rider.

The Erex is a remarkable bike and a big improvement on the rear wheel powered fat tyre bikes that we have seen. Dont confuse this ebike with generic Chinese frames and components. This has German wheels, Swiss tyres, LG battery components and great mid-range Shimano drive components. The bearings are all sealed, the hardware is 95% stainless steel, and the Kinetic controller has self-diagnostic readout and thermally protected.

The frame is is made of chrome-moly (aircraft grade) steel and multi-process primed and painted. it comes in red or British racing green.  the frame size is medium large, which allows a more upright riding position for general terrain.

The dual wheel drive system on the E-Rex prevents the front wheel floating to the side over little sticks and pebbles which is a problem for fat tyre bikes and especially rear-wheel powered ones. . The enormous contact area of fat tyres can be a problem on loose surfaces, but with dual wheel drive, it floats over all kinds of sand, snow, shingle, mud, in  a remarkable way, much better than rear wheel electric assist e-bikes. In addition the front wheel drive has corrective steering, which means that it is pulling you into the steering direction you have given it. You will immediately realize this benefit if you get into sand or mud. Dual wheel drive makes it very easy to ride.

The E-Rex has name brand, non-generic components completing the bike and the electronics are a big step above what you will find in NZ today for a fat-tyre bike. You will pay a bit more for this bike, but check the details, you are getting better value, name-brand reliable components on the Erex.

Comes with our 11 amp hour (400 watt hour) frame mount, aircraft grade Sony hi-density celled,  battery.  The larger capacity 14.5 amp hour (540 watt hour) battery is also stocked for your selection.

Get ready for on/off-road riding fun with our E-Rex
