Apparently this came from a Bafang rep at Eurobike,

Here's a pic of the motor at the show, I assume with the new display (and a funky looking battery case behind I imagine).

I just had some correspondence with the guys at lectric cycles and they are recieving test units in the next few weeks. Production will begin in september with a view to start selling early november. These will be the ERAD systems and way over priced but if they are getting them i imagine so is everybody else.

Im wondering if the different sizes in bottom brackets means they fit everything inbetween for instance im looking at a scott genius that has a 92mm BB so does that mean the 100mm will fit.

Karl's thoughts. He is rather intimate with the current motor, and should be able to give details when he gets one. Maybe it shows up in November?

Aren't the nylon gears for noise reduction and durability under normal usage?Well, we don't have much data regarding the MAX drive and it's hard to compare the reliability and quality.
As for all these E-bike races, E-bike world championships, they look like joke to me. If a non-pro guy like me can do 500km/day, if we put some elite athletes on one of these machines, they can easily do 800km/day.
So, 600km/day in TEAM events is not that impressive.
But Bafang enjoys the economies of scale and they produce in millions for the Chinese market.
Here is a quick tour that Pete did early this year.
This is the new MAX drive and I wonder if they are still using the Nylon gears?
The problem as noted by Karl of Electric Fat Bike is that they are still using Nylon gears and trying to push 750W + through them.
Such Nylon gears are prone to teeth damage or what Karl says "peanut butter gear"
Great article here about the replacement of Nylon gears.
Honestly, I'm not sure if Bosch or Derby is doing any different.
Their motors are also using something similar.

So, may be Bosch and Derby has corporate leverage and vitamin-M to push their drive into EU markets while Bafang is primarily focused on Asian markets.
May be the mid-drives are still work in progress.....
ahhh, my bad.
Good on the longevity, but that's the lower power end of the scale for sure. The newest setup is putting out a LOT mroe power and thus going to probably be easier to shred those gears.

They should do well under 250W, which is the limit in EU.
I think even upto 500W, it should be alright. Panasonic and Yamaha mid drive motors have been very reliable and I hope the new batch BBSo02 with updated controllers are on par...

Invariably someone will put 72 volts and 30 or 40 amps into the HD. Wonder what will happen?
Paul at EM3ev has discussed the switch from nylon to composite on the MAC motor. He makes it clear that the nylon are somewhat short lived. I would like to know if Bafang goes with something like composite gears on the HD.

I am not sure how much this cost but it looks like the Max drive system.

I found a youtube video of an installation of a bafang. Looked like a nice and easy system to switch to. Sorry I can't share it . I'm unable to find it again. Very well documented by home cyclist. Thanks for the links to Motor pics. and specs.

From the ES forum on the BB02 and 750W:

I hope Bafang redesigns the mechanical parts of the new 1000 watt instead of just reusing the old BBS01 design. The 750 watt BBS02 uses the same mickey mouse plastic gear and clutch as the 350 watt. It left me stranded many miles out in the mountains. I chose to de tune my BBS02 to 500 watts to keep from having more problems. Doug Snyder at California e-bike has fantastic customer service. He turned my defective BBS02 around in 1 day!!
