TASMANIAN designer Simon Williams has braved rain and hail, savage dogs and dangerous drivers.

But he says it was all worth it as he embarks on a brave challenge to change an Australian icon - the famous red postie bike.

The Kingston-based designer is putting the final touches on his design that he hopes will make life easier for posties worldwide.

The revolutionary three-wheeled electric bike has been created for Design Island, an annual program that showcases the state's designers.

Mr Williams' bike will not only be silent and energy efficient, it will have greater stability, is capable of reversing, can go off-road and carries larger loads safely.

He said it would also be faster and travel longer distances than its petrol-powered predecessors.

"The prototype includes technologies like regenerative braking, battery management and a reverse gear," Mr Williams said.

"The bike itself presents a possibility for change in the perceptions and awareness of many Australians.

"Most would never give a second thought to an alternative."

Mr Williams worked as a postie for 18 months to get a better understanding of what changes were needed.

The bike he has developed is expected to be on the road by the end of the month.

The current Honda CT110 is built exclusively for Australia Post making it the highest selling motorcycle in the country.

It has a 105cc four-stroke engine and a four-speed gearbox.

Arts Minister Michelle O'Byrne said this year's program featured more than 50 designers.

Why three wheels? Why reverse?

I love the idea of an electric postie bike. But as we all know, people resist change. It should probably be designed to be similar to the ct110. I've said before that converting an actual postie bike would be an interesting experiment, to gauge the reaction.

good work, though!

It's a tilting three wheeler, that you can balance without having to put your foot on the ground, and when you get off, it stands on its own. The ability to tackle tough terrain at slow speeds is excellent.

The tilting, and righting mechanisms are dead simple - and failsafe.

The prototype has two X5's in the rear wheels, controlled with two Kelly boxes....hence - regen braking and reverse built in.
As a Postie your always finding yourself backing down a driveway, or pushing backwards to get out of a tight spot, or to get back to the mail box you just missed....so reverse is essential.

There are three inbuilt luggage racks - one above each rear wheel, and theres one that pulls out from the back of the seat.

The CT110 is a beast, but not perfect - and not a purpose built mail delivery vehicle

Interesting, and a good point about reversing. I hadn't thought about that. I think as long as its performance is as good as what it replaces, it's ok by me. I think we need to try and overcome the perception that EVs are toys.

Is there a video of one working? Or a computer simulation, perhaps. I'd like to see it in action.

Interesting stuff.
Here is a fixed link:

They talk a lot about Vehicle to Grid (V2G) support where the EV supports the electrical grid during the night hours but there appears to be no discussion or projections on how that would effect battery life.

What govt department really needs an AC conversion?
Rubbish collection.

They already have a big ICE motor to run the hydraluics.
Just need the AC motor added to regen to a small pack.

So the short answer is NO but the long answer is YES.
