"The law simply states" .. it would be the first time.

See thie third post in this thread from myself.


You didn't quote the law. You quoted an RTA brochure.

Are you saying that the 10 year old NiCds in my electric drill aren't

Are they working like they always did?
If so, they would be the exception to the rule.
Not that I think the DIY use s really use.

I use my electric drills pretty much on a daily basis. My construction
glazier son uses the same brand of drill, Hilti, and he uses them
often enough to require two or three charges per day. He has four and
five year old drills. OTOH a replacement battery pack for one of those
is about $200, so they might just be better batteries than the ones
that come in the $25 drill kit. :-)

Toyota are claiming they have not had to replace a set of batteries
in a Prius yet. Some of those are 8 years old. What kind of batteries
do they have?

Yes, but are they working like they always did?
The promise is there, but 8 years isn't 10 years which the tech claims.

Who knows.

You think they'd get it wrong?

Anyway, what we need that we currently do not have easily available, is a
kit of left crank with cog, bolt on motor, electronic throttle and
multiple battery packs (24hr turn around for longer life) and home
recharger.

Like this one?

Convert your bike to Xtracycle, fit Stokemonkey and go!!

Brochures and guidelines = advice

Advice about how to drive/ride is not always what is legally required. Eg.
Advice "You should always ride in bright coloured clothing". Legal
requirement - nil

Maybe you need a lowrider bent(not as far to fall)
or even a trike(hard to fall off, especially at low speed)

actually I'm in a funny foreign place at the moment which has icy bits all
over the joint for 1/2 the year. I've been seriously considering a recumbent
trike for a little while now (given we have such good bicycle paths here). I'm
wondering (based on the other post) if I'd be better with an electric hub
style (cos there's not much in hills here {givaway point on location}) but
since there are some short steep ones would an electric motor with higher
torque be better (assuming I can engave / disengage upon hills).

hmmmm

Then you're more interested in torque than power. For example, my
200W electric hub motor wouldn't pull a sailor off your sister, but
with quite gentle pedal input will sail along flat ground at 30-40kph
(or about 25 without pedaling). I also have a 200W K Mart electric
bike which uses a motor with a reduction gearbox (10:1 IIRC). It has
gobs of torque, but tops out at 22kph motor assist. It's on a
freewheel, so the motor has no input over that speed.

How long ago was the Kmart elec bike on offer?
$?


You can
also get geared hub motors which will have more torque for a given
wattage than a non geared hub motor, but I've never tried them.

I've seen them around.

Current investigation is which bolt on motor (for chain drive) are
around Vs $.



Hopefully I don't need to pull either out of mothballs when I finally
do get back on a bike!

Just take it easy and listen to your body.

I like the look of tadpole trikes, though I'm sure I could still find
some way to hurt myself

Well... you can roll a trike if you go too hard into a corner and
don't lean enough.

Clearly you would have to practice fast turns to be sure you get it
right.

flyingfurniture.com.au has trikes you know....

It keeps making this "ker*lunk *clang*" sound.
