Re: Aussie 200 Watt Limit Thread

Re 3rd party insurance.

Different states do things very differently.

If you are driving an unregistered vehicle in nsw,you have NO 3RD party insurance.
It's the way things are here.

Re: Aussie 200 Watt Limit Thread

We don't have any bike lanes or paths here. David That's a shame for you. Just one of my local councils has over 500km of shared paths. For example, I can ride the entire 22km trip from home to work and not have to ride on one road.Sure I have to cross a few, but I'm not riding on them. Luckily, it...

Re: Aussie 200 Watt Limit Thread

I've been running a "500" watt hub motor on my trike for a few years. Never even had a second glance. Helps that it's hidden in the small rear wheel with panniers on either side. Add to that I'm not a dick where and how I ride, and I don't have any concern at all. In reality, that little hub motor c...

Re: Aussie 200 Watt Limit Thread

i have always thought that speed limits (not power limits) were the way to go. i would think 25kmh while on a shared path, and 40kmh elsewhere. then things become very simple for enforcement, and allows sensible power to be used in our bikes. 35kg limit wouldn't do for me. my trike weighs more than ...

i once had an Airzound. its an air horn that is pumped up to 80psi by bike pump, and it's super loud. 110DB i think from memory.

im planning to add another to my trike soon.

Re: "Zephyr" - Finally, the "v4" Fechter/Goodrum/Hecker BMS.

hi George. i can't help as far as interfacing the zephyr to the DC-DC converter, but as yours (and mine for that matter) is still wired to the batteries the same way as it was originally, even with the DC-DC tripped off by those two wires, there will always be a very small draw from the batteries. t...

Re: Cycle Analyst V3 preview and first beta release

speed errors are regular on my CA V3.

it's caused by contact bounce in the reed switch.
i routinely see max speeds of over 600kph :)

i think your idea that it has to be sustained for some time before being logged as a valid speed would help eliminate the error.

Re: "Zephyr" - Finally, the "v4" Fechter/Goodrum/Hecker BMS.

the little relay we used is linked above, it's working fine.

there was zero voltage on these lines with the DC-DC on.
Vincent, the installer measured this.

hi george, yep, shorting those two wires from the DC-DC converter will shut it off. it's still connected to the pack, but it's only drawing milliamps or less. just he leakage current from the large caps inside it. i have updated the thread on priuschat now and the first full charge and discharge cyc...

Re: Cycle Analyst V3 preview and first beta release

limiting by watts will have a constant power regardless of battery voltage.
limiting by amps, will reduce the power as the voltage drops.

It doesn't really look like your helmet did its job properly, it looked like it just cracked, rather than compressed. It looks like it thought 'frock it, Greg can take it' before wussing out.

200w sticker (check)

reflectors front and rear (check)
lights front and rear (check)

stealth paint (not quite !)
but the motor is well hidden under the rear pannier bags.

most people don't even realize i have a motor installed.

you might want to contact Maurice and Abraham at glowworm bicycles in Marrickville.

they can certainly help you with a kit that will do what you want.
and i too would recommend the 500W geared hub motor approach. that's what im running, and it's a fantastic climber.
