Predominantly due to legal reasons. It will always be a risk to ride it on a public road (as it breaks all the electric bike rules in AU) and I think I might quit while I am ahead and have had my fun with it. I'm limited to where I can ride it legally.
So it got me thinking If I really want motorbike performance why not just build a bike that can be road registered.
I'm kind of drawn to the 80s bikes like the Honda CB750. Nice wide simple frame and can look kind a cool as a cafe racer. "Hey after driving the dorky Imiev around I need something with a bit of cool factor"

Anyhow I stumbled across this great example of a simple build that wasn't to exotic...(expensive) and looks like it would cover most of my needs as a bike to get around on to the local town or a lazy joy ride in the local hinterland area.
Could be handy transport On days when I don't have enough PV to charge a car but stil want to get out of the house. I'm sure I can spare enough to charge a motorbike.

I recently picked up (yet to take delivery of) 32x40Ah calb CA cells. I purchased them to use as a range extender for the Imiev but my wife wasn't to keen on the idea of heavy battery's and inverters strapped behind the back seat of the Imiev inches from our 8yo daughter in the event of serious crash. A Fare point that I couldn't live with the results if it went bad. Using them just for trips when I'm the only one in the car (not often) wasn't great value.
So considering 25 cells gave that guy in the linked example 60km range and 100kph top speed along with a significant weight reduction over the stock 750's curb weight. Then if I have 32 cells to play with I might be able to push the range out a little more running closer to 100volts still be well within or more likely under the stock weight.
Fabrication of all the parts (That for the most part looked very simple) Battery boxed, motor mounts would be in house. So really just other than the bike it's self. A motor and controller package and a few small accessory is all that would be required.
Contractors, battery's bms, Cycle analyst, shunts, fusing, cable, terminals and raw material for fabricated parts I have already.
So motor and controller suggestions (I'm still not 100% keen on brushed motors as used in the example I linked to) Perhaps even some dona bike suggestions if my ideas are not the best.
How are the rules with emotor bike conversions. Its my understanding its a lot easier than trying to get a car through all the hoops?
