I'm looking to add a half or full twist throttle. Can anyone tell me if there is an available twist throttle that has the same connector?
Otherwise, is the throttle wire on the BBS a three wire?

Its a standard 3 wire hall throttle setup so any hall throttle should be fine.
Unless you can get a matching plug, you will need cut the plug off the thumb throttle and attach to your new throttle.

Lectric Cycles have a half twist with the Bafang plugs.

So the 500W version pumps out the same power as 750W. Interesting. Can you do me a favor and measure the width across the motor/ controller housing? Just want to compare it the 750W version. I am pretty sure they will be the same but just want to be 100%. Looks like there is no real point buying the 750W version. May as well save $30 and get the 500W version.

I was thinking along the same lines today as the 750w is out of stock, but then I saw in the programming thread "amigafan2003" could not program his 500w version above 18A without getting error code 11, where as the 750w is 25A
Does this really matter? I don't know, just put me off the idea a little

I'm willing to bet that the 500W version has a different Firmware that prohibits the controller from allowing more than 18A. If everyone can post the stats of your firmware in the Programming thread, maybe we can start a crude database of versions and options. - and once the latest firmware file is released perhaps those of us with 500W units can "upgrade". 8)

The 750W version is actually set at 20A in the software. amigafan2003 is getting 1100W peaks from his 500W drive. I am getting 1050W peaks with my 750W version. It does sound like they have different firmware version though.
I wonder if the 750W version can actually be set higher then 20A. Not that i would really want to risk running above 20A anyway.
I know what you mean about being put off slightly though. If both are available, I think I would still chose the 750W version for the sake of $30 bucks.

Amigafan2003 is running 15s lipo vs your 12s lipo, I guess that's what's equaling the watts out between you,

I see. I missed that. Makes more sense now.

Another thank you Sam. Flat Foot as a descriptor makes sense to the oldsters I've tried to describe the concept to. In conversation I've used Flat Foot and Foot Forward interchangeably. Trek Pure describes their version as "Feet flat on the ground."
Regardless my next bike will be another FF. But I'm trying to sort out which have a 68mm BB. I wish more used IGH rather than cassettes. 3 spd IGH version don't have lugs for brake mounting, rather use coaster brakes. I'm hoping one bike here will work out with an Eboost. My Trek Pure does look like a spaghetti factory, but it does make me happy.

If 25 amps, the 750w should be able to put out 1350w, using a 58 top of charge v lithium battery. I mean 14s lico/limn or 16s lifepo4.
But it should be taking a pretty steep uphill start to see it, or a high gear start.
Both kinds are the same motor? Just controllers different? I know it must have been said, but 90 pages,,,,

Wattage is correct. I see ~1200W max on 12S LiPo.
The 750W and 500W versions may have a different controller or even the same controller with different firmware that limits the Amps. - It could just be Bafang's way of providing a lower spec'd motor for countries that don't allow 750W. This is my speculation, of course. Perhaps lcrewse or Cellman can confirm?
With speed delimited now, I can get my 750W motor up to 37.8mph on the downhill without pedaling. It still tops out around 31 mph on the flat without my help.

Best chain to use? I'm currently in chain land trying to understand and learn about them today.
Any suggestions on resources for learning appreciated.

I recently fitted a 250w for a customer and snapped the old chain - due to the chainline bend (had to reuse front derailleur as a chain keeper). I'd recommend fitting a new chain to any BBS install.
Also, recently had to splice in a new three wire throttle and can confirm that the wires inside follow the usual three wire colour convention (red to red pos, black to black neg, and the other colour is signal).

Not only it measures amps,volts and watts but also give you..

Top right gives u cur volt, left cur amps, bottom right cur watts and bottom left
cycle thru all other readings. I was looking for something that measures temperature
as l have already cooked my first middy motor. This watts meter came with all the
additional bonus of all the peaks and lows measurement similar to he CA but at
a fraction of the price.

Thanks, they're a PIA, no chain sizes. Is there a common link count for a ten speed chain? I'm running an IGH. 126 link if I'm getting it right.Melbourne said:

In regards to the watt meters, I watched this guy (great info every time, btw), and he's showing the difference between Turnigy, Watts Up and Precision GT meters.

Well it's been six weeks waiting for my BBS02 750W unit from aliexpress vendor NNEbikes.
No battery yet. Drive finally arrived today - after continual lies and false tracking codes, Michael Wong shipped me a 48V 500W unit and presumably hoped I wouldn't notice.
The 36v 350W unit I ordered from Greenbikekit on the same day arrived nine days later.
