BBSO3 (third generation) feature set announced yet?

I searched on BBS03 Bafang and 8Fun . I did not find much. I wonder if gear switching will be improved with a sensor?
Do motor improvements coincide with battery improvements, or are they independent of each other?
For BBS02. HPC kit has the following enhancements

max torque curve: 115Nm
[? from 0 to 580 RPM]
1.0 peak HP
[? and 60Nm @ 1175 RPM]
[? 140F temperature]

Note: I added the question marks as a placeholder until resolved

  1. Custom Single Speed 38T sprocket for nearly 25% more torque and higher efficiency (Red or Blue)
  2. We also optimize on throttle and Pedal Assist response to be more benign on chains and sprockets so you are less likely to damage gears with a smoother engagement.
  3. We have added approximately 25% more torque than the stock system, made the system run cooler/more efficient and minimized chain problems.
  4. 26A 9 FET controller that we get custom from the factory
  5. We have full access to every parameter of these motors and provide custom profiles on our 1200W+ systems in PAS 1, 2, 3 to allow them to be EU legal in PAS1, 500W legal in PAS 2 and US legal with 750W maximum output in PAS 3.
  6. We have tested these units with our dynojet dynamometer in our shop and the results were very positive! Please Look at the last picture for actual dyno of this system on one of our bikes.
  7. Compared to stock, the narrow wide chainring provides more consistant chain retention and allows the motor to be geared down for higher torque and efficiency
Since you can use all 10 speeds of the bike with your motor, your top speed can vary from 7 mph with huge torque for hill climbing to 30+ mph on the straightaways- all with one motor!

Does this help with mashing?

SRAM X1 11-Speed X-HORIZON™ Rear Derailleur

(Link Removed - No Longer Exists)

With CAGE LOCK™ technology in the rear derailleur, wheel removal and installation—as well as chain installation—becomes faster and simpler. Just pushing the cage forward to create slack and lock it into place.

ROLLER BEARING CLUTCH™ rear derailleurs deliver maximum drivetrain stability—even through the most punishing terrain. With ROLLER BEARING CLUTCH™ technology, derailleur bounce and chain slap are eliminated without sacrificing precision.

Developed specifically for SRAM 1X, X-ACTUATION keeps shifting sharp and consistent across the entire 10- to 42-tooth cassette.

The X-HORIZON™ rear derailleur’s ‘straight parallelogram’ design limits all movement to the horizontal axis, which makes ghost shifting impossible while also reducing shift force. For quicker, more exact shifting, the large upper pulley offset design maintains a constant chain gap across all gears.

SRAM X-SYNC™ 1X chain rings provide the highest level of performance and durability. The SRAM X-SYNC™ tall square teeth edges engage the chain earlier than traditional triangle shaped teeth. The sharp and narrow tooth profile, as well as rounded chamfer edges, help manage a deflected chain. To provide the best possible performance in muddy conditions, the X-SYNC™ chain rings have been designed with mud-clearing recesses for the inner chain links and rollers. Engineered in Germany, X-SYNC™ rings are an integral part of the SRAM 1X™ drivetrain.
