In NSW it says that bicycle is something that is designed to be
propelled by human power and it can have a motor as an auxiallary
power source.

The law may be different where you are, so you might want to say where
that is.

Zebee

from AUSTRALIAN ROAD RULES - SCHEDULE 99 (as quoted in the current
NSW law via austlii.edu.au)

"" bicycle " means a vehicle with 1 or more wheels that is built to be
propelled by human power through a belt, chain or gears (whether or
not it has an auxiliary motor), and:
(a) includes a pedicab, penny-farthing, scooter, tricycle and
unicycle, but
(b) does not include a wheelchair, wheeled recreational device,
wheeled toy, or any vehicle with an auxiliary motor capable of
generating a power output over 200 watts (whether or not the motor
is operating)."

Eh? Since when does not having a speedo qualify one to break the
speed limit? We don't have indicators either, but we are still
required to indicate right (but not left).

One[1] of my motorcycles isn't required to have one either. (as it's pre
-82, I think that's the ADR that required them)

When I checked with the RTA they said that I didn't have to have a
speedo but the cops expected me to obey the speed laws.

When I honk the bent down Melville St of an evening I sometimes wonder
if they ever set up a speed trap there... Of course I'd frame the ticket!

[1] well 3, but 2 of them have speedos.

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

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

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. :-)

Who knows.

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

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.

Both motors peak at about 520W electrical input (electric motors are
rated on their continuous power output) but the K Mart bike climbs
hills much better. I measured the K Mart bike at 140W at it's top
speed on flat ground with no headwind and no pedal input. 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.

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

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

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