Hey Snowsurfer, yes i recall the cop sting near Urabne Cyclist. My experience back then was the cops stopped me for stopping under the red light where the stop was 20 feet back due to an uneven intersection, the white delimiter line was faded out so i couldn't see it. anyways, they let me go with a warning, all they cared about was that i had a helmet, bell and reflectors.
I agree with cops regarding bikes needing to follow road laws. You know, after that encounter with the lady cop, I now take my left turn by first crossing all the way, without turning left, then i stop, make a u turn on the shoulder and take a right turn with traffic. I do this not necessarily to be a model citizen but to keep alive on the road. :-))
rearding the disk brakes , yes I would like to have a look.. problem is my front fork doesn't accomodate disk brakes, so Urbane Cyclist says, I'd have to replace the fork $$$ .. so instead i got arch rival brakes, they do a decent job stopping me.

What capacity Ping do you have? Is it 10Ah or 15Ah?
What sort of range are you getting using full-throttle, with no pedalling whatsoever?
I figure with the 10Ah, it would be something like 36km, and with the
15Ah pack, it would be like 48km. Am I in the ball park?

15 ah capacity
ok, full throttle? hmm, well, i don't really go that fast all the time, kind of dangerous, but i can tell you that the range exceeds 36 km.
here's how you need to see it, i think. How many km per ah am I getting. That i can better answer based on my experience:
if you're gentle with the throttle and accelerate slowly etc, and still rely mostly on the motor with very minimal pedalling, like i do, then you can get 4 km per ah, which means we're talking close to 60 km. i pedal to get the bike up to speed to help in the acceleration phase, which i would say lasts about 5 seconds (let me do this in my head again, yep.. one mississipi, two mississipi, three mississipi.. i'm losing track of the esses in that word :- )
on a windy day, this goes down to 2 km per ah, 30 km.
makes sense ta ya?

Shocked at the range you were getting, then realized that you have 72V...and at 15Ah, which is a big battery pack(s). You're using about 18Wh used per kilometer, which seems good.
Assisting with accelerating definitely helps. Also, watch the headwinds. If you are getting a lot of headwinds, try to pedal as much as you can. I destroyed my booster pack when I tried to throttle it all the way.
50km/h is a really high speed, and should be used only sparingly on ebike. Generally cruising speed is probably around 32-40km/h. That about right to you?

32-40km/h is exactly right
and with a 72 volt system i can maintain that speed regardless of the conditions without taxing my battery pack
take for example a car. it can do 180 kmh, but in reality people don't usually drive at that speed. they cruise at 40-60. same idea.

I can go up to 34mph with a 48v Lifepo4 10Ah battery to work but reduce to 25mph when busy traffic on the street.

Oh yeah, and if you switched to 6" rotors, for discs, you won't notice much of a difference. Maybe a bit more stopping power, but only a tad. The difference is huge if you go to 8" rotors.
You're on a rear hub motor, so you could try putting discs up front.
There is a sale at pricepoint. But go for the 200mm+ or 8" discs, you'll thank me for it when it saves your life on your 72V/ 51.2km/h set-up.

quick update:
regarding my new immediate start controller not working: problem is with the hall circuit on the 408 motor.
controller is fine.
how did i find out? I just recently upgraded to a 5304 crystalyte motor, my 72 volt immediate start digital controller works fine on that. it's really cool finally having immediate start again (woohoo )!!
this tells my that the fault was with my 408 motor (hall wires/circuit) ...
cheers
