E-motorbike conversion and rego issues
Has anyone got rego on a motorbike conversion recently?
Looked into the rego aspect for EV bikes a couple of years ago (I am in Qld). Seemed that there is no well defined process to get engineers approval for a modification like there is for cars (NCOP14). Basically anything you do to a bike makes it an ICV, and there are open-ended costs and time spent in getting it registered. Rego is a matter of if not when.
This put me off entirely. I'd love to hear if this situation has changed.
Converting an already registered bike is chancy (I thought of that too) If you hit anything, you have an illegally modified vehicle, and insurance won't pay.
Technical hurdles mainly revolve round space for batteries, IMHO. Nice to hear about those newer water-cooled Motenergy motors, I was looking at the double sided ME0913 (I think) at the time. Being able to have a gearbox would be nice too, but again it's the space issue.

Interesting.
Never noticed that line before in the NCOP14.

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

The WA DOT change of vehicle details form says:
DoT wrote:If the engine change is not a like-for-like replacement and the
engine configuration has changed (i.e. different number of
cylinders, power rating, engine make/model/type, engine capacity
or fuel type), then a vehicle modification approval must be sought
from DoT.
So the short answer is NO but the long answer is YES.

That does seem to be a loop hole in the paperwork at least.
As far as I know no one has a problem registering a motorbike conversion.
As for QLD I don't know.
Given how little there is for the ADR's for a motorbike I would think it's more open slather
Most of it comes down to common sense and safety.
There are DoT registered engineers for this.
But like you say it is a gamble.

The DoT website in WA was updated a year or two ago and it's very helpful for this sort of stuff.

All well and good if you live in WA... when I spoke to engineers who had approved car conversions, and also their QLD Transport counterparts, there was much head scratching. Nobody seemed to have a better answer than "build it first and we'll see what happens", which is not on when you're talking about $10-12k for a decent donor bike and decent batteries. I imagined that if you came up the same weight or lighter, and with less power, you would be OK, but my confidence was not returned.

So the "normal" process for a car conversion is to fill out an application to modify form. (Form F1854 CFD)
It is generic for "light vehicles" under 4.5T.
It doesn't say anywhere it doesn't include motorbikes.
The form is supposed to be filled out and submitted BEFORE starting.
So the risk is the donor vehicle cost.
After that ADR's apply and as a GUIDE the NCOP series of documents.
Now looking through the ADR's there is little subject matter on engine side other than emission/pollution aspect.
Like I said open slather with common sense and safety thrown in.
As for the documents I suspect that these will have to be updated to include provisions for Motorbikes.
Doesn't help you now tho...
On the plus side it usually comes down to the guy doing the inspection.
And he'll probably be pretty happy seeing something different.
So as long as it's rideable, brakes and doesn't electrocute him pretty good odds on getting it registered.

One of the NCOP suggests +/-20% power variation.
BUT it does say continuous...

Yeah pretty pointless complying to 10/20G impact load on the battery box.NCOP14 wrote:These guidelines do not apply to ADR category L-group vehicles and motor cycles.
So the battery box survives a crash but the bike and rider are now a can of baked beans.

Earl Gilcrest (0417229723) is a Brisbane engineer that has undertaken approval of several motorbike conversions in Queensland. I suggest you talk to him to find out what is required.

Excellent - someone always has the answer.
I'd be interested, as with others, what he has to say.
Even if it just general advice.

Double sided
What would be the reason for this?

It's a version of an earlier motor (can't recall the number, sorry) which has twice the number of windings, one set on each side of the rotor magnets. They are axial flux motors, so the magnets are on a disc rotor. Not sure if the later motors follow this pattern though, but judging by the low winding resistance figures, they probably do (two windings in parallel)
EDIT: the single sided version is the ME0709. You can see the parallel connection of the windings in this picture of the ME0913 motor: http://kellycontroller.com/mars-0913ete ... p-874.html

OK, I just spoke to Earl and he was very helpful.
He requires a description of the bike (model/year) and list of major components used for the conversion. Based on inspections along the way, he prepares a report for Qld Transport with photos, weights and so on. They will issue the approval in a couple of weeks from there (he can't just put a plate on like they do for a car conversion). There is no need for an application to modify a vehicle to QT first, as there was in prior years. A bike conversion is NOT an ICV (as I was advised years ago)
His advice is mechanical commonsense:
- no cutting of frames or structural bits
- no modifying of brakes, forks or suspension
- keep weight under the original, and weight distribution similar
- comply with NCOPxx requirements for electrical side of conversion
His costs run to $700-800 if all goes well.

Interesting.
Sounds promising.
Still not clear cut like a car conversion.
I guess there isn't enough of them to justify the paperwork updates.

I'm thinking an ME1616 motor (watercooled, 20kW) and 72 or 84V worth of NCM cells, if I can fit them into the frame (big if). Anyone managed to snag these recently, and at what price? I notice EVPower is advertising 72Ah versions available.

You might find smaller capacity cells are easier to work with. Sometimes you can get lucky, but often the numbers don't work out for single 25 Ah cells. It might be that 20 Ah would fit perfectly. So using multiples of 5 Ah cells is practical in that instance.

Any problems paralleling strings of cells in practice? I can imagine all sorts of problems with unbalanced strings trying to charge each other - are protection diodes or other forms of isolation used?

Not if the cells are paralleled first. And assuming your cells have been vetted for self-discharge and internal resistance, they will parallel up just fine.
